android下實現程序不操作一段時間，執行另一個程序

粘貼項目中代碼，你應該可以看得懂的！

@Override
	public boolean dispatchTouchEvent(MotionEvent ev) {
		// TODO Auto-generated method stub
//		Toast.makeText(getApplicationContext(), "操作ing", Toast.LENGTH_SHORT)
//				.show();
//		 Log.i(TAG, "操作ing");
		 resetTime();
		return super.dispatchTouchEvent(ev);
	}
	
	private void resetTime() {
		// TODO Auto-generated method stub
		mHandler.removeMessages(SHOW_ANOTHER_ACTIVITY);//從消息隊列中移除
		Message msg = mHandler.obtainMessage(SHOW_ANOTHER_ACTIVITY);
        mHandler.sendMessageDelayed(msg, 1000*60*1);//無操作5分鐘後進入屏保
	}
    
	private Handler mHandler = new Handler()
	{
		@Override
		public void handleMessage(Message msg) {
			// TODO Auto-generated method stub
			super.handleMessage(msg);
			if(msg.what==SHOW_ANOTHER_ACTIVITY)
			{
				//跳到activity
//				 Log.i(TAG, "跳到activity");
				 Intent intent=new Intent(FaultActivity.this,ScreenSaverActivity.class);
				 startActivity(intent);
			}
		}
	};
