This is the gallery of the item corresponding getview
public View getView (int position, View convertView, ViewGroup parent) {
ImageView image = null;
if (convertView == null) {
image = new ImageView (mContext);
} else {
image = (ImageView) convertView;
}
/ / load images using ImageLoader
imageLoader.displayImage (resourceList.get (position) getPicUrl (), image, options.);
WindowManager wm = (WindowManager) mContext.getSystemService (Context.WINDOW_SERVICE);
int screenWidth = wm.getDefaultDisplay () getWidth ().;
image.setLayoutParams (new Gallery.LayoutParams (screenWidth, screenWidth * 211/516));
return image;
}
------ Solution --------------------------- -----------------
can not get the second , it is not clear ah , have not encountered such a case, the multi- point code affixed to look at how to set the , if you do not rely Gallery , I recommend using viewpage, personal recommendations .
------ Solution ---------------------------------------- ----
about beating about the interface automatically adjusts the picture , right ? Mobile passed, and adjust to the normal position , without displaying a picture that you do not load the obvious next picture
------ Solution --------------- -----------------------------
your position is not never changed ? To share what you refer to it. Feel you can change it to complete the above problem

The above is an example of their landlord controls , pictures need Luzhu own definition ,
what is the layout file
<?xml version="1.0" encoding="utf-8"?>hoping to help you
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<!-- 定义一个ImageSwitcher组件 -->
<ImageSwitcher android:id="@+id/switcher"
android:layout_width="320dp"
android:layout_height="320dp"
/>
<!-- 定义一个Gallery组件 -->
<Gallery android:id="@+id/gallery"
android:layout_width="fill_parent"

100 points nobody either . .

what about shiver , you are referring to slide after you have a rebound effect
------ eference ------------------------------------ ---
Yes, it has been playing . . Can not get a second picture
------ eference ---------------------------------- -----
Gallery not used , try to use the next SurfaceView? Most games are made with SurfaceView, display pictures of what properly properly
------ eference ------------------------ ---------------
viewPager I used the next, not as gallery, while dragging with viewpaper, dragging down the range can not be too large, otherwise the meeting scroll . Instead of moving around .
help facie this gallery first question it.
------ eference --------------------------------------- < br> thank you brothers above reply , but their pit dug themselves buried . . . .
The reason is the use of Image-loader, then I put Image-loader memory , disk cache removed, as well. . The disadvantage is that every time from the Internet to let him fetch it.
saying that the problems with the framework really is hard to find ah. . .
options = new DisplayImageOptions.Builder ()
. showImageOnLoading (
GetItemId.getDrawableResIDByName (context, "suma_default_poster"))
. showImageForEmptyUri (
GetItemId.getDrawableResIDByName (context, "suma_default_poster"))
. showImageOnFail (GetItemId.getDrawableResIDByName (context, "suma_default_poster" ;) )
/ /. cacheInMemory (true )
/ /. cacheOnDisc (true)
