 final Handler handler = new Handler(){ 
       public void handleMessage(Message msg) { 
            switch (msg.what) {     
                case 1:     
                   et.append("1");
                    break;     
               }     
               super.handleMessage(msg); 
           }   
       }; 

       TimerTask task = new TimerTask(){ 
              public void run() { 
               Message message = new Message();     
               message.what = 1;     
              handler.sendMessage(message);   
            } 
         };

 

　　　　//这里在程序中运行，比如在按与事件中或程序启动中

 　 Timer timer = new Timer(true);
     timer.schedule(task,1000, 1000); //延时1000ms
