Activity data transfer between the jumps and

 

Activity phone screen can be seen as one of the pages ( personal understanding ) is often encountered in development with data from an Activity to another Activity, done Web development knows that in order to pass parameters from a html page to another page is the easiest url = "http: \ \ www.google.com.hk?parmter=xxx". Here 's a look at Android's Activity parameter passing between .

 

first create a activity_main.xml

 

         View Code   

   

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:paddingBottom="@dimen/activity_vertical_margin" 
    android:paddingLeft="@dimen/activity_horizontal_margin" 
    android:paddingRight="@dimen/activity_horizontal_margin" 
    android:paddingTop="@dimen/activity_vertical_margin" 
    tools:context=".MainActivity" > 
 
    <EditText 
        android:id="@+id/txtMsg" 
        android:layout_width="fill_parent" 
        android:layout_height="50px" 
        android:text="将要传递的内容" 
         /> 
 
    <Button 
        android:id="@+id/btnsend" 
        android:layout_width="fill_parent" 
        android:layout_height="50px" 
        android:layout_alignParentTop="true" 
        android:layout_centerHorizontal="true" 
        android:layout_marginTop="54dp" 
        android:text="跳转" /> 
 
</RelativeLayout>

  

 

 

jump in MainActivity which add logic code

 

  

    private Button btnsend; 
    private EditText txtMsg; 
 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
        super.onCreate(savedInstanceState); 
        setContentView(R.layout.activity_main); 
        txtMsg = (EditText) this.findViewById(R.id.txtMsg); //获取到文本编辑控件 
        btnsend=(Button)this.findViewById(R.id.btnsend); //获取到文本编辑控件 
        btnsend.setOnClickListener(new View.OnClickListener() {    //按钮监听事件 
            @Override 
            public void onClick(View arg0) { 
                // TODO Auto-generated method stub 
                Intent intent=new Intent(MainActivity.this,OtherOneActivity.class); 
                intent.putExtra("name",txtMsg.getText().toString()); //设置要发送的数据 
                startActivity(intent); 
            } 
        }); 
    }

 

 

finally built a OtherOneActivity inheritance Activity, used to receive data

 

  

    private TextView labmsg; 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
        super.onCreate(savedInstanceState); 
         
        labmsg=new TextView(this); 
        setContentView(labmsg); 
        Intent intent=this.getIntent(); 
        String msg=intent.getStringExtra("name"); 
        labmsg.setText(msg); 
    }

 

 

Special Note: Be sure to register in AndroidManifest.xml new Activity

 

  

 <activity android:name=".OtherOneActivity" android:label="OtherOneActivity"></activity>
