android - Android ResultReceiver in multi threaded environment

Question

I have an activity which, essentially, starts multiple threads in order to get multiple resources from network. I update the UI after receiving the notifications from these threads using ResultReceiver mechanism. The code snippet looks like below,

public void onReceiveResult(int resultCode, Bundle resultData){

    switch(resultCode){

    case 1: updateData1();
        break;

    case 2: updateData2();
        break;

    case 3: updateData3();
        break;
}

As, its the main thread which updates the UI elements on receiving the notifications from these threads, I was thinking it will be a good idea to make method onReceiveResult synchronized. Any comments? Is there is anything else that should be taken care of in order keep it efficient and safe?

不，这无济于事，它会阻塞线程。而是在 UI 线程上运行将修改 UI 的代码，否则您将遇到问题，具体取决于调用此 onReceiveResult 的位置...

activity.runOnUiThread(new Runnable() {

           @Override
           public void run() {
               updateData1();
           }
});
