android定時任務的實現

直接上代碼

        int runnableInterval= 5000;//切換間隔

private Handler handler = new Handler();  
        private Runnable runnable = new Runnable() {  

        public void run() {  

     do();//要定時執行的任務  

          handler.postDelayed(this, runnableInterval);  

          }  

       }; 

調用

handler.postDelayed(runnable, runnableInterval); 

登出

@Override
protected void onDestroy() {
// TODO Auto-generated method stub
//停止定時任務
handler.removeCallbacks(runnable);

super.onDestroy();
}
