实现的功能:在指定的时间之后执行某个操作

废话不多说，直接上代码

public class TimerTestActivity extends Activity{        @Override    public void onCreate(Bundle savedInstanceState)    {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);        Timer timer = new Timer();        timer.schedule(timerTask, 3000);// 在指定时间执行timerTask    }        TimerTask timerTask = new TimerTask()    {        @Override        public void run()        {            Message message = new Message();            message.what = 1;            handler.sendMessage(message);// 发送消息        }    };        Handler handler = new Handler()    {        public void handleMessage(Message msg)// 处理消息        {            switch (msg.what)            {                case 1:                    setTitle("Hello,I am Harvey");                    Toast.makeText(TimerTestActivity.this, "Hello,I am Harvey", Toast.LENGTH_LONG).show();                    break;                default:                    break;            }        }    };}
