HandlerThread mHandlerThread;（全域性變數）

mHandlerThread = new HandlerThread("AdShieldStrategyThread");
mHandlerThread.start();
mMyHandler = new MyHandler(mHandlerThread.getLooper());

private class MyHandler extends Handler {
        public PollHandler(Looper looper) {
            super(looper);
        }

        @Override
        public void handleMessage(Message msg) {
          doSomething();
        }
}
 

2：可以像使用UI執行緒的handler一樣執行post,postDelay,sendEmptyMessageDelayed等方法。

3：宣告stop方法，釋放資源

mMyHandler.getLooper().quit();
mPollHandler = null; 
mHandlerThread = null;
