来自不同线程的处理程序未从主线程接收消息

Question

我相信我不理解Handler如何传递/接收消息。

我在另一个线程上创建了一个处理程序，然后让主线程向它发送一条消息。我是这样做的

 public void startAniHandlerThread(int timer){
    final int sleeptime = timer;
    int test2;
    Thread thread1 = new Thread(){
        public void run(){

            Looper.prepare();
            Log.v("loop","looping");
            Handler handler = new Handler(){
                @Override
                public void handleMessage(Message inputMessage) {
                    Log.v("Thread handler", "checking");
                    if(inputMessage.what == 10) {
                        if (inputMessage.arg1 == 2) {

                            Log.v("Thread handler", "stop");
                        } else if (inputMessage.arg1 == 1) {
                            Log.v("Thread handler", "continue");
                        } else{
                            Log.v("nothing", "nothing");
                        }
                    }
                }
            };

            Looper.loop();
        }
    };


    thread1.start();
}

以下是我尝试从UI线程向其发送消息的方式：

public void stopAniHandlerThread(){
    Handler newHandler = new Handler(new Handler.Callback() {
        @Override
        public boolean handleMessage(Message msg) {
            return false;
        }
    });

    Runnable newRunable = new Runnable() {
        @Override
        public void run() {
            Handler handler = new Handler();
            Message message = new Message();
            message.what = 10;
            message.arg1 = 2;
            handler.sendMessage(message);
        }
    };
    newHandler.postDelayed(newRunable, 2000);
}

这是我得到的日志（我希望这个被调用，但它没有：

 Log.v("Thread handler", "stop");
