Will Android SD card resource manager API do ? Still need to manually write ah ? ?
I want to write an SD card reader txt documents , but also can not manually enter the path ah ? ? Xiangnong a resource manager to achieve.
------ Solution ---------------------------------------- ----
android with sdcard related classes on an Environment, which did not seem to realize this API function method you say it .
------ Solution ---------------------------------------- ----
multi-level traversal to do a similar thing folder
listview loaded with record path .
Click for path then passes through the intent of what value then open

android PopupWindow how to drag
A similar effect was done right, I can now write to drag , but the second drag began to move from the original location .
following code to achieve this is PopupWindow press the button , move the movement can be achieved throughout the PopupWindow , initialized to Gravity.BOTTOM position for the first time since the window at this location , so the move is correct, but the second started , click the button to start moving the moment , it will suddenly jump to the starting position , then move
------ Solution ------------------------------------- -------
try to put int dx int dy become a member variable. It is a local variable .
------ Solution ------------------------------------ --------
debug this problem if it should be solved. Most appear in popup.update this method , you re in ontouchend method in setting its location setposition.
------ reference --------------------------------------- < br> the two values should be something to do with it, it will get moved when a new value ah
case MotionEvent.ACTION_MOVE:
int dx = (int) event.getRawX () - lastX;
int dy = (int) event.getRawY () - lastY;
popup.update (dx, -dy , -1, -1);
This place should be negative , or move up and down just reversed, do not know why

[Share] androidpn when you push the problems
If Baidu or Google Search. " android push "keyword, a considerable part of the article are said androidpn. You can also see some people say to use it, someone said Tucao instability, loss of function, maintenance workload. androidpn This paper attempts to make a pooled analysis of past lives.
Visit androidpn official site, we can understand the following basic information:
androidpn full name is Android Push Notification.
This is the Korean source on an open source project on sourceforge.net, the document is in Korean.
recent version of the update time is 2010-11-05, which is about two years ago.
visits from China, accounting for 81% of total visits. Please click on this link to look at the current statistics.
the above basic information indicates that this is not a very mature project (seemingly personal maintenance), but it does have a lot of Chinese people are interested.
I believe there are many students know why people on androidpn so interested, this is situation ah: Because Google official GCM (previously called C2DM) can not be used in the country. In addition, domestic and before that a third party is not available handy push service. So, we had to do: their practice. Start from scratch? Too much work, too uneconomical. So from the beginning of open source. And also happens to be open source project, specifically for the Android Push the afterlife, it androidpn it. mqtt There is no integrated so well you can quickly run up.
but androidpn build up, the situation? CSDN programmer on a beautiful article androidpn Push Probe is hot. Of this article raised a few questions:
androidpn server receives the message, how do you know which user you want to send?
Once the server is restarted, the client does not seem to auto-reconnect, you need to interrupt the user's own back-Service and then restart the application.
androidpn server does not save the message. It is a message that will be sent out there, even if the client did not online, it does not re-issued.
authors like that, not just settle for the environment to build up, and thinking to do for your business needs. Resolve the issues raised under her:
The first question is relatively simple, go to customize the user system, the business part of the user system needs to correspond with androidpn.
The second problem is the small detail, androidpn client does not have to do these details.
The third problem is the most important. androidpn behind Openfire , is XMPP IM server, the message content is not going to fall, that is only stored in memory about offline messages. If you want to produce with the need to consider the transformation here.
follows from androidpn technical foundation to a depth analysis.
androidpn is an integrated solution, which is based on the XMPP open source components. Based on that server Openfire , client-based Smack, XMPP open source components which two are the most common of the two. androidpn using the Spring framework to do a Web tier, the XMPP IM components integrated together to achieve Android Push functionality. Therefore, androidpn availability from the following aspects:
its dependence on XMPP IM protocols and communication mechanisms, whether it is suitable for Android Push scene.
whether it is Android Push needs to do the necessary customization.
first aspect, XMPP protocols and open source components. XMPP is a mature IM (instant messaging) protocol, based on XML text ways, flexible and powerful. Most foreign countries are based on XMPP chat services, such as: Gtalk, Facebook Chat, iMessage, etc. Because of this, so some of the open source XMPP component availability is also good, the domestic many emerging chat tool is fully based on the XMPP beginning to develop open-source components, such as rice talk.
However, the author has realized a similar experience mobile chat App speaking, XMPP open source components have their problems, needs large-scale transformation:
XMPP protocol complex redundancy, the client cost flow, costs of electricity;
open source XMPP server (androidpn chose Openfire) limited capacity of a single point, the cluster program complex, immature.
For these reasons, and taking into account a wide range of technically more uncontrollable transformation, where the team so I just started using XMPP open source program, and later completely cut to the realization of their own technical solutions on the.
The second aspect, Android Push demand scenarios, in addition to the message can be pushed to the client in a timely manner, what other basic needs it? Here cite two examples: first, to ensure that the message can reach. Whether there is a mechanism to ensure that messages are not lost, for whatever reason. Second, to specify a group of people push messages. anroidpn based XMPP IM component is not considered these, you need to do a lot of custom transformation.
To sum up, the use of androidpn can simply do: push the message to the client . However, to make it suitable for developer needs, and run in a production environment, you may need to do a lot of custom development work. From the author communicate with multiple developers get feedback, up and running in a production environment where a lot of problems.
mentioned above, there is nothing available before the domestic third-party messaging handy push service, so we have to consider their own structures. Recent domestic third-party news push service opened, it is the aurora push, ordinary developers can always sign up, download the SDK to do integration, the whole process can be completed three minutes.

Android Live chat encryption of information between user and serverprocesses
I now understand that when the user sends a login account and password . The server then verify the correct return a cookie, and a key, the user wants to save the cookie to use key encryption , use the time taken out from the database decrypted ( My purpose is to prevent others from stealing a cookie that model user action ) , there is a request to plus the cookie, the server receives the authentication cookie after aging , can accept the request
But using Ethereal tool found username, password directly exposed , and if the account password when sending the first encrypted and then decrypted server , then to the public key, if someone decompile , do not you still be able to get the public key

Android camera camera horizontally flipped
Ask a question
If the preview image when correctly photograph into a [thumbnail image flipped horizontally flipped] also, how is it?
ps: the code is qualcomm platform 2.3, rear camera, no problem, before the camera image flipped horizontally.
I read this article
http://blog.csdn.net/daisyhd/article/details/6000962 feel there should be a place to set jpeg encoding from right to left or from left to right, but did not find a specific location. Watched for several days did not get,
always see a oriention setting, but regardless of the setting into 090,180,270, there will not be flipped horizontally happen ah
------ Solution --- -----------------------------------------
was writing camera hal layer? Should be driven not supported or did not write
------ Solution ------------------------------ --------------
jpeg coding problem is not, nor is it oriention setting problem.
In fact, you said that the front camera take pictures, because the mirror effect, so the preview is correct but the photos are mirror lights, according to the text of this most obvious.
If I describe this situation, then you need to be provided by hardware manufacturer datasheet, to modify the viewfinder / camera mirror set or options. General hardware will provide such register settings.
------ Solution ---------------------------------------- ----
I do is flat, only the front camera, as it happens I am also responsible for this camera. Just can not understand what you say "stop setting mirroring register."
taking photographs Echo has about 1s preview is inverted? Your situation is very strange that I have not encountered before. If you have modified the register set, then the thumbnails of the photos should be the opposite and viewfinder, and photos as well preserved.
I can confirm that s_mount_angle not achieve the purpose of what you expect, it can only modify oriention folding dump the whole picture, which can not be obtained by the center axis mirrored screen.
For you mentioned "jpeg encoding from right to left," I really have not seen so to set the front camera, it sounds more like image processing tools will go thinking I may be out the ^ _ ^
------ Solution ------------------------------------ --------
exif information problems, exif There is a rotation field.
------ Solution ---------------------------------------- ----
absolutely impossible.
Front camera requirements: thumbnails and photos consistent, and with the viewfinder opposite. That is the moment to re-photograph will be folded once. I'm pretty sure.
just get iphone test it, as well.
------ reference --------------------------------------- < br>
Thank you moderator.
camera does have a register set up a mirror, and I was changed before the preview displays the normal, if sanpshot register again when the modification times, photographing the end of the write back to the initial value, you can also take pictures normally, but back significant is backwards. Why they suspect jpeg encoding issues.
question, camera driver probe set attributes:
s-> s_camera_type = FRONT_CAMERA_2D ;/ / BACK_CAMERA_2D
/ / s-> s_mount_angle = 90; / / 0x13
s-> s_mount_angle = 270; / / 0x10
If it is before the camera, this should be the number s_mount_angle, this value is determined by how?
------ reference --------------------------------------- < br> in the camera driver in SENSOR_PREVIEW_MODE, SENSOR_SNAPSHOT_MODE respectively set to mirror the corresponding value register
have the following two questions:
1. taking photographs Echo has about 1s preview is inverted
2. vertical screen only echo wrong, horizontal screen photo shoot is inverted. But here is the same as the setting drive.
depressed ~
When I want to keep running with this setting in the drive mirroring register, not only in the initialization settings such as mirroring register a value, first ensure that anyway preview are normal, but in the jpeg encoding settings when taking pictures from right to left, the image can not it just 'jpeg encoding from right to left' This place is not found, this idea is not it?
tone through the front of the camera's heroes take a bubble ah ~
------ reference ------------------------ ---------------
'If you have modified the register set, then the thumbnails of the photos should be the opposite and viewfinder, and photos as well preserved. '
This is wrong, right, thumbnails and viewfinder should not do the same, preview image is photographed image is the way I see are like front camera
------ reference --- ------------------------------------
At first I also suspect that this value, But jpeg photos shot using a mobile phone to read metadata via IrfanView is no such flag of
------ reference ---------------------- -----------------
Oh, thank withheld enthusiastic reply.
today camera.java indeed see explanatory notes before the camera will flip around the central axis, that is a separate app to do so.
'thumbnails and photos unanimously' front camera should be so, but before the camera viewfinder contrary requirements, so flip?
some faint, engage in a few days it is not a problem? I am now either vertical or horizontal position, and imaging are the preview thumbnails
about folding up. Compare to find the machine to see tomorrow go wrong?
------ reference --------------------------------------- < br> on the front camera and preview imaging should flip, looking for a different platform reference machines from different manufacturers, some will and some will not flip, the conclusion:
bug or feature is determined by demand!
eventually have to be changed.
------ reference --------------------------------------- < br>
Ha ha ha ...... ask customer needs it ~ ~ ~
------ reference - --------------------------------------
Oh, this should be changed according to customer requirements , not their own is how to go nuts, Oh, I also do double camera, and more exchanges
------ reference ----------------- ----------------------
"not go nuts on how", and now I can not put it how.
before the camera will shoot out horizontally flipped, luckyboy brother, do not let it know how to flip ah?
say that you want to modify the mirror register, snapshot to modify, and preview image can indeed be the same, but the echo has flipped, evil camera ah ~

In this case there is a problem, that is the side to take the phone to take pictures, thumbnails of people upside down. Edit thumbnails, so consistent with the preview, and photos On the contrary, the problem is solved.

CAMERA there is a problem when the horizontal. Whether IPHONE, Samsung's mobile phone, or something else, there will be a direction 180 degrees upside down? Online brothers said to be G-SENSOR is not sensitive to the issue, there is this BUG decoding?
If the preview image when correctly photograph into a [thumbnail image flipped horizontally flipped] also, how is it?
ps: the code is qualcomm platform 2.3, rear camera, no problem, before the camera image flipped horizontally.
I read this article
http://blog.csdn.net/daisyhd/article/details/6000962 feel there should be a place to set jpeg encoding from right to left or from left to right, but did not find a specific location. Watched for several days did not get,
always see a oriention setting, but regardless of the setting into 090,180,270, there will not be flipped horizontally happen ah
------ Solution --- -----------------------------------------
was writing camera hal layer? Should be driven not supported or did not write
------ Solution ------------------------------ --------------
jpeg coding problem is not, nor is it oriention setting problem.
In fact, you said that the front camera take pictures, because the mirror effect, so the preview is correct but the photos are mirror lights, according to the text of this most obvious.
If I describe this situation, then you need to be provided by hardware manufacturer datasheet, to modify the viewfinder / camera mirror set or options. General hardware will provide such register settings.
------ Solution ---------------------------------------- ----
I do is flat, only the front camera, as it happens I am also responsible for this camera. Just can not understand what you say "stop setting mirroring register."
taking photographs Echo has about 1s preview is inverted? Your situation is very strange that I have not encountered before. If you have modified the register set, then the thumbnails of the photos should be the opposite and viewfinder, and photos as well preserved.
I can confirm that s_mount_angle not achieve the purpose of what you expect, it can only modify oriention folding dump the whole picture, which can not be obtained by the center axis mirrored screen.
For you mentioned "jpeg encoding from right to left," I really have not seen so to set the front camera, it sounds more like image processing tools will go thinking I may be out the ^ _ ^
------ Solution ------------------------------------ --------
exif information problems, exif There is a rotation field.
------ Solution ---------------------------------------- ----
absolutely impossible.
Front camera requirements: thumbnails and photos consistent, and with the viewfinder opposite. That is the moment to re-photograph will be folded once. I'm pretty sure.
just get iphone test it, as well.
------ reference --------------------------------------- < br>
Thank you moderator.
camera does have a register set up a mirror, and I was changed before the preview displays the normal, if sanpshot register again when the modification times, photographing the end of the write back to the initial value, you can also take pictures normally, but back significant is backwards. Why they suspect jpeg encoding issues.
question, camera driver probe set attributes:
s-> s_camera_type = FRONT_CAMERA_2D ;/ / BACK_CAMERA_2D
/ / s-> s_mount_angle = 90; / / 0x13
s-> s_mount_angle = 270; / / 0x10
If it is before the camera, this should be the number s_mount_angle, this value is determined by how?
------ reference --------------------------------------- < br> in the camera driver in SENSOR_PREVIEW_MODE, SENSOR_SNAPSHOT_MODE respectively set to mirror the corresponding value register
have the following two questions:
1. taking photographs Echo has about 1s preview is inverted
2. vertical screen only echo wrong, horizontal screen photo shoot is inverted. But here is the same as the setting drive.
depressed ~
When I want to keep running with this setting in the drive mirroring register, not only in the initialization settings such as mirroring register a value, first ensure that anyway preview are normal, but in the jpeg encoding settings when taking pictures from right to left, the image can not it just 'jpeg encoding from right to left' This place is not found, this idea is not it?
tone through the front of the camera's heroes take a bubble ah ~
------ reference ------------------------ ---------------
'If you have modified the register set, then the thumbnails of the photos should be the opposite and viewfinder, and photos as well preserved. '
This is wrong, right, thumbnails and viewfinder should not do the same, preview image is photographed image is the way I see are like front camera
------ reference --- ------------------------------------
At first I also suspect that this value, But jpeg photos shot using a mobile phone to read metadata via IrfanView is no such flag of
------ reference ---------------------- -----------------
Oh, thank withheld enthusiastic reply.
today camera.java indeed see explanatory notes before the camera will flip around the central axis, that is a separate app to do so.
'thumbnails and photos unanimously' front camera should be so, but before the camera viewfinder contrary requirements, so flip?
some faint, engage in a few days it is not a problem? I am now either vertical or horizontal position, and imaging are the preview thumbnails
about folding up. Compare to find the machine to see tomorrow go wrong?
------ reference --------------------------------------- < br> on the front camera and preview imaging should flip, looking for a different platform reference machines from different manufacturers, some will and some will not flip, the conclusion:
bug or feature is determined by demand!

Android SDK SipDemo not register
I use the official SDK comes in SipDEMO, I packaged into APK, in HTCT328d models installed on the phone. Open, it will pop up directly interface allows you to fill SIP-related information, fill out, it will prompt Registered successfully! Then I can play wifi sip phone, but I installed on another phone, such as LGP880, open, no interface let me fill out the registration information, and I myself in the settings are completed, the interface did not suggest any words, notes, my two handsets are Android 4.0.3 Will, SIP Demo What is the phone requirements? I know that as long as the Android 2.3.3 system to support the above, but why is there above me tell what is going on? Great God there is to know, please tell younger, be grateful!

android under four 4-way split screen play HD h264 format rtspstreams
Display with videoview do so. Play all the way no problem at all, no card, it is real, but it can not play much, but also error. Automatically pop up a dialog box can not be played.

ah, backward incompatible! If you must compatible with 2.3, you have to replace it with something else.

compiled out of the library with a 4.0 on a 2.3, of course, there may be a problem. . .

Are you this so used inside the 4.0 platform related things? ?

path is right, why would fail to load it? ?
permissions in the application loading libraries which you need to declare? ?

identify with so library files not related error message is clearly pointed out to him you did not find the library file to manually push it, looking like the path / data / data / com.mediatek.cmmb.app / lib / libcmmbsp.so, or put here, and system / lib under all push it a try.
------ reference --------------------------------------- < br> different versions of android source code changes or big quantity, from the log can not see because of the link library function, it is best to place the library source code corresponding android projects can be seen compiled.

actually originally set, only in 4.0 platform is adopted. Why 2.3 No No load! !
------ reference --------------------------------------- < br> That is, if there is no source, and a set of so this app is not valid in 2.3, which is obsolete?
------ reference --------------------------------------- < br> I tell you,. so use it, have to take your package name, class name, method name, set with. so inside, like to use. so
------ reference ------------------------------------ ---
you can look for the original. so use it, the corresponding engineering package names, class names, method names, can only be set exactly the same with the original works, you can use this. so. What other people say is not compatible with versions compatible, completely okay, lead you astray.
------ reference --------------------------------------- < br> so to speak, and so this app was originally set, is the 4.0 runs OK, and then migrate to version 2.3 error. Because before the originally set, so the package names, class names, method names are the same, right?

Android About the handler and static variables consulting
A program written in the class, there are some time-consuming operation, use the thread + handler, the time-consuming operation into thread execution, completion handler to send the message, and then update the UI.
The question now is what I wrote in the class handler, always prompts a warning:
This Handler class should be static or leaks might occur
I searched the Internet this warning, the resulting solution is
Handler class should be static type, or they may cause leakage. In the process queued messages in the message queue maintained its target Handler class applications. If Handler is an inner class, then it will remain it in the outer class references. In order to avoid the disclosure of this external class Handler should be declared as static nested class, and use the weak application of the outer class.
about usage examples are:
assume that the handler class is B, this way, handler defined as static, in order to use the handler class defined in class A, a number of variables, these variables in class A have to be defined as static.
I would like to ask about, so a lot of static variables affect the operation of the program do? It will not be a waste of memory?
Thank you ~
------ Solution --------------------------------- -----------
Haha, it should be no problem. This is not a lot of static. .
------ Solution ---------------------------------------- ----
your thinking a little a little bit wrong
static class is to disconnect the link MyHandler and outside class, so that the inner class and outside class does not have any contact is static class purposes.
You do not need to declare a large number of the Activity by static variables to provide to the handler to use (this code is not only unsightly but the design is very unreasonable). Because you have a mActivity MyHandler weak reference so you can call mActivity any public functions and variables.
So, you just need to be defined in mAcivity public XXX getXXX () method to provide MyHandler you need a variable package together, we can be friends.
------ Solution ---------------------------------------- ----
If the handler is not static, then when after this activity destory may not be garbage collected, thus causing the so-called memory leak
------ reference ----- ----------------------------------
dozen variables did not affect me?
------ reference --------------------------------------- < br>
ah, really a awoken ah, thank you to answer, I understand ^ _ ^
------ reference -------------- -------------------------
hello, and then ask you a question, I used mActivity direct access to which it belongs Activity The variables (including private), can be accessed. No use setter and getter (found using getter and setter, then a lot of variables to be set getter and setter), I do not know my way in the design of this access whether it is reasonable?
Also please advise, thank ~

Android display word and pdf documents, how to achieve it
Hello everyone! Android
I was a novice, recent projects, of which there is a demand for Android application is to view word and pdf format documents (PS: not with intent to call third-party software to open Documentation oh ~), but Android does not directly display the word and pdf document view. So the rookie checked the Internet for a long time a very long time wow ==.
For the word, many people say is poi parsed, and then re-written in html, and finally with WebView display. So, this is the easiest way to the most common Mody? I feel very troublesome == there are other ways it?
For the pdf, also seemed to parse Apache's pdfbox pdf, do have to pay the written html? I got a MUPDF reader source, does not seem to do that. But also a lot of trouble a lot of trouble.
Well I was a novice, not to mention parse html source files and replication difficulty is that we can re-written in html, I always feel no insurance, can guarantee exactly what the source document format, Some of the content can be guaranteed not to be missed it. . . Also, some people say poi only parse. Doc then replicated html, against. Docx difficult inflicted html? But someone said poi resolution. Docx is maintained continuously updated technology, and poi parse. Doc that some components have not updated. I am even more confused, if I work hard to learn poi parse. Doc, this component sound it can be fully resolved correctly? And if. Doc parsing Well,. Docx can solve the problem poi thing?
I just do not want to waste more time detours, so here ask where the great God who csdn give suggestions and direction, okay?

android opengles phone wake graphical interface textures are gone,graphics white
When the phone from the lock screen to unlock and found a running program to draw graphics all turned white;
original graphic textures are gone;
If you exit the program and reopen it then appears normal;
I want to lock the screen, then it should go through onSurfaceChanged method; method so I suspect a problem;
below the main posting my renderer code
To be honest for some method calls are not very clear ...
Here is the draw method:
mWorldCubeList.get (i). draw (gl);
then a draw is as follows:
really do not know the screen from the lock screen to unlock the need to deal with what, how texture is gone ...
hope someone can answer!!
------ Solution ---------------------------- ----------------
detailed looked under public void onSurfaceCreated (GL10 gl, EGLConfig config)
This method, when using OpenGL ES, once stopped rendering thread, the context will be lost, the program which will be used to image resources are recycled, so you need public void onSurfaceCreated (GL10 gl, EGLConfig config) This method loads the resources in the picture
------ reference ---------------------------- -----------
I think you need to AbstractRender class which override onResume () method, using OpenGL on the picture to reload

Android2.2 JSON problem
Lane project uses json yesterday , it was found a very egg pain problems , android2.2 comes org.json.JSONArray did not actually remove method . So the Internet contains a org.json package , running up and run to remove it encounters an exception , checked the Internet is a packet collisions . Since I have not changed , changed json-lib, results and error , checked the Internet actually said google does not support json-lib, do not know is not true . So decided to rewrite JSONArray, estimate the level is not enough, re- finish or a variety of issues .
Will you next time you use android2.2 development is how to deal json, comes with egg package does not remove too much pain .

This SystemProperties.set (string name, string value) we are very familiar with it, what have encountered this problem
When the program first set SystemProperties.set ("frank", "1");
Then keep setting SystemProperties.set ("frank", "2");
String lang = SystemProperties.get ("frank"); shown as a;
SystemProperties.set ("frank", "2"); actually invalid. . . Added a while (true) {
If reading is less than 2, it has been SystemProperties.set ("frank", "2"); reading, brake;
}
can. . SystemProperties is reflective. . Oh, how could this not be a continuous, slow response Mody. .
------ Solution ------------------------------------ --------
SystemProperties permission is required by the prefix for verification.
You can set the program to UID System, and then use System permissions Properties, such as service starts with.
------ Solution ---------------------------------------- ----
SystemProperties is prop service operating it, this is not necessarily synchronized
but to prop service responds to the request, do deal with it
------ reference ----------------------- ----------------
Oh prefix validate these times spent oh. . Justified
------ reference ------------------------------------ ---
Xianxie try
------ reference ------------------------------------ ---
looked at the source ~ ~ should be, LS two expert said right. Yes, thanks, oh
------ reference ------------------------------- --------
I also encountered this problem, I told the landlord, like a dead loop. . . The result was invalid, SystemProperties.set ("persist.sys.onoffsounds", "0"); log out has always been a hit to begin setting "1", did not understand why. . . Solving

Android sqlite how to create and play a database in the specifiedpath
The default is the package / database / test.db
SQLiteDatabase db = openOrCreateDatabase ("test.db", Context.MODE_PRIVATE, null);
I want to change the path to
/ mnt / sdcard / helloworld / test.db
can do it
------ Solution -------------------------------- ------------
this hope useful to you , you can store and read directional positions
http://blog.csdn.net/zcljy0318/article/details/7299223
------ Solution ------------------- -------------------------
private File xx = new File ("/ sdcard / wwq / cs.db") ;/ / specify the database path
private SQLiteDatabase sql;
sql = SQLiteDatabase.openOrCreateDatabase (xx, null);
Cursor csxx = sql.rawQuery ("SELECT JSH, JSBH, URL FROM CSXXB", null);
------ reference -------- -------------------------------
great God to ask, he said the article "SQLiteOpenHelper.java ) this class, create a database file path is used for incoming contex of getDatabasePath , this can not be modified ( at least I did not find ) . "
If the same security in two ways , I still use the default path to good
give suggestions , thank you

[Android] ExpandableListView an incredible problem! ! !
me first say that my project scenario: I have such a requirement, slide to the right ExpandableListView the Child, Child of dynamic display [Delete] button .
This is my Child node layout code:
The first two are display data, and finally a Button is the delete button, the default is not displayed. When I was at the interface above the slide when the slide position to obtain the View, and then to get through findViewById Button, Button to display the status of the final set, the code is as follows:
then debug emulator above, the following are debugging steps:
1, which is just to run the program when the state [as shown below]:
2, I start the second set, and in the first slide trigger Delete Child above results as shown []:
As shown above, the button is displayed successfully, and the back shows the [Pos] current location, but I do not understand: why the current position of two?
3, above me in the second group, the second slide [Child above effect is as follows]:
here is normal, position 3 .
4, then, is where the title appeared, I clicked the first group, the first group is expanded, the emergence of a bizarre phenomenon:
shown: second group of second Child button in the display to the first group of a Child above, why is there such a problem?
please help out, here I have studied for a long time, after all, I do not know how it is, first thank you!
------ Solution ------------------------------------ --------
pointToPosition is AbsListView interface obtained is pure location, rather than the first of several groups of several, if you want ExpandableListView using estimated also getExpandableListPosition and getPackedPositionGroup, getPackedPositionChild used in conjunction with job.
second question, estimates and adapter in getChildView realization about, is not there like if (convertView == null) else like this, you look at the code for the button check processing is not and not only set the display settings hidden
------ reference --------------------------------- ------
For the second question, I really was just a show, not hidden, but I show the current clicked Child of Button, even though I did not hide it, but it should not be another group went off to! This is something I'm confused!
------ reference --------------------------------------- < br> My understanding is that you go through if (convertView == null) ... else ... to create a child view, could the system when calling getChildView originally belong to the second group of the second a first group of the View assigned first, the second and the second group of a re-created, resulting in a phenomenon

how not solve the second problem?

This is my Child node layout code:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal" >
<TextView
android:id="@+id/textChildTitle"
android:text="No Data"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:paddingTop="5dp"
android:paddingBottom="5dp"

android:layout_gravity="left|center_vertical" />
<TextView

</LinearLayout>
The first two are display data, and finally a Button is the delete button, the default is not displayed. When I was at the interface above the slide when the slide position to obtain the View, and then to get through findViewById Button, Button to display the status of the final set, the code is as follows:
//获取手指开始按屏幕的位置和最后抬起手指的位置
int pos1 = this.elv.pointToPosition((int)e1.getX(),(int)e1.getY());
int pos2 = this.elv.pointToPosition((int)e2.getX(),(int)e2.getY());
//先判断是否触发Child的delete事件
//如果起始位置【pos1】和结束位置【pos2】是在同一个【Child】并且这个【Child】的位置有效
//并且滑动距离大于100px，则触发Delete
if (pos1 > -1 && pos1 == pos2 && (e2.getX() - e1.getX() > 100) && (e2.getX() - e1.getX() < 200)){
//获取当前Child的【Delete】按钮
Button btnDel = (Button)elv.getChildAt(pos1).findViewById(R.id.btnDel);
if (btnDel != null){
btnDel.setVisibility(View.VISIBLE);
btnDel.setText("删除"+ pos1); //我将当前所在的位置【Pos1】写到按钮上面，方便调试
btnDel.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(MainActivity.this, "POS:" + ((TextView)((View)v.getParent()).findViewById(R.id.textChildMoney)).getText(), Toast.LENGTH_SHORT).show();
}
});
Log.i("BTN Show","SHOW:" + pos1);
//btnDel.setfo
return true;
}
}
then debug emulator above, the following are debugging steps:
1, which is just to run the program when the state [as shown below]:
2, I start the second set, and in the first slide trigger Delete Child above results as shown []:
As shown above, the button is displayed successfully, and the back shows the [Pos] current location, but I do not understand: why the current position of two?
3, above me in the second group, the second slide [Child above effect is as follows]:
here is normal, position 3 .
