方式1:執行單一定時器任務

 				Timer timer = new Timer();
                    timer.schedule(new TimerTask() {

                        @Override
                        public void run() {
                            // TODO Auto-generated method stub
                            mHandler.sendEmptyMessage(CONNECT_PLATFORM_START)
 
;
                        }

                    }, 2000);

方式2:執行多個定時器任務

 		Timer timer = new Timer(); 
        
        TimerTask task = new TimerTask()
        {
    	    @Override
    	    public void run()
    	    {
    	        //TODO
    	    }
    	};

		TimerTask taskS = new TimerTask() {
			@Override
 

			public void run() {
				//TODO
			}
		};
		TimerTask taskB = new TimerTask() {
			@Override
			public void run() {
				//TODO
			}
		};
    	
    	timer.schedule(task, 0, 3000);
		timer.schedule(taskS, 200, 1000);
		timer.schedule(taskB, 200, 5000);
