定时器模板

 

定义变量：

private final int TIMEID = 1000;
private Timer m_timer = null;
private TimerTask m_timerTask = null;
private Handler m_timerHandler = new Handler()
    {
        @Override
        public void handleMessage(Message msg)
        {
            super.handleMessage(msg);
            switch(msg.what)
            {
                case TIMEID:
                    onTimer(msg.what);
                    break;
            }
            
        }
    };

 

  onTimer()就是定时去执行的函数，可直接定义；

 

 开启关闭定时器函数：

private void startMyTimer()
    {
        stopMyTimer();
        m_timerTask = new TimerTask() {  
              
            @Override  
            public void run() {  
                // 需要做的事:发送消息  
                Message message = m_timerHandler.obtainMessage(TIMEID);
                m_timerHandler.sendMessage(message);  
            }  
        }; 
        m_timer= new Timer();
        m_timer.schedule(m_timerTask,10,
                10);
        
    }
    private void stopMyTimer()
    {
        if(m_timer != null)
        {
            m_timer.cancel();
            m_timer = null;
        }
        if(m_timerTask != null)
        {
            m_timerTask.cancel();
            m_timerTask = null;
        }
    }
