也許是我太不用心，每次寫延遲執行程式碼都要百度查一下，雖然是板磚的但是也太不專業了。所以寫下此篇blog熟記一下。

private final int DELAY_TIME = 1 * 60 * 1000; // 1000ms為基準，此處為1min
Runnable delayExecuteRunnable = new Runnable() {
	@Override
        public void run() {
		// execute codes.
        }
};

private Handler mHandler = new Handler(); // define handler
mHandler.postDelayed(delayExecuteRunnable, DELAY_TIME); // start execute

mHandler.removeCallbacks(delayExecuteRunnable); //cancel execute
 

不取消的話就會迴圈執行。
