Android 在其他线程中更新UI线程的解决方法

mHandler = new Handler() { 
   @Override 
   public void handleMessage(Message msg) { 
        //操作界面 
       myText.setText( 来自网络的信息); 
      super.handleMessage(msg); 
   } 
  }; 
public class MyThread extends Thread { 
     public void run() { 
​    ​    ​    // 耗时操作 
​    ​    ​    ​loadNetWork(); 
            Message msg = new Message(); 
            mHandler.sendMessage(msg);//向Handler发送消息， 
      } 
 }

public void onClick( View v ) { 
        new Thread( new Runnable() { 
                public void run() { 
                       // 耗时操作 
​    ​    ​    ​    ​    ​      loadNetWork(); 
​                          myText.( new Runnable() { 
                                  myText.setText( 来自网络的信息); 
                          }); 
                 } 
        }).start(); 
}

//UI线程中执行 
new DownloadImageTask().execute( "www.91dota.com" ); 
private class DownloadImageTask extends AsyncTask { 
    protected String doInBackground( String... url ) { 
         return loadDataFormNetwork( url[0] );//后台耗时操作 
    } 

    protected void onPostExecute( String result ) { 
          myText.setText( result ); //得到来自网络的信息刷新页面  

   } 
}
