如何發送使用resultreceiver數據，而類是從線程

Question

延長我有我的一些數據發送給我的活動

public class baseApi extends Service { 

@Override 
     public int onStartCommand(Intent intent, int flags, int startId) { 
    //get the receiver object 
     resultReceiver = intent.getParcelableExtra("receiver"); 
} 


    private BroadcastReceiver datachanged_receiver = new BroadcastReceiver() { 

     @Override 
     public void onReceive(Context context, Intent intent) { 
       //HERE I send some data like this 
       Bundle bundle = new Bundle(); 
       bundle.putString("data", "My data goes here"); 
       resultReceiver.send(100, bundle); 
}}; 
} 

在同一個類中服務類我有一個類擴展「線程」 ，並且這個類也打算使用resultReceiver向UI發送一些數據，但它不會給出任何異常，但在UI端沒有接收到數據，而resultReceiver通過廣播接收器發送數據的效果很好。

public class baseApi extends Service { 

@Override 
     public int onStartCommand(Intent intent, int flags, int startId) { 
    //get the receiver object 
     resultReceiver = intent.getParcelableExtra("receiver"); 
} 


    private BroadcastReceiver datachanged_receiver = new BroadcastReceiver() { 

     @Override 
     public void onReceive(Context context, Intent intent) { 
       //HERE I send some data like this 
       Bundle bundle = new Bundle(); 
       bundle.putString("data", "My data goes here"); 
       resultReceiver.send(100, bundle); 
}}; 

class actionThread extends Thread{ 
    @Override 
    public void run() { 
     super.run(); 
     try{ 
         //send this data to the service   
      Bundle bundle = new Bundle(); 
      bundle.putString("data","More data goes here"); 
      resultReceiver.send(200, bundle); 
     } 
     catch(Exception ex) 
     { 

     } 
    } 

} 
}

在android中，您可以使用Handler與UI線程進行通信。改用Hanlder.Post或HandlerThread。 「
