在后台线程中运行处理程序消息

您可以简单地做到这一点：

private Handler mHandler;private HandlerThread mHandlerThread;public void startHandlerThread(){    mHandlerThread = new HandlerThread("HandlerThread");    mHandlerThread.start();    mHandler = new Handler(mHandlerThread.getLooper());}

然后调用：

mHandler.postDelayed(new Runnable() {        @Override        public void run() {          // Your task goes here        }    },1000);
