直接上代码
public class MainActivity extends Activity { private int title = 0; private Handler handler = new Handler(){ public void handleMessage(Message msg) { switch (msg.what) { case 1: updateTitle(); break; } }; }; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); Timer timer =new Timer(); timer.scheduleAtFixedRate(new MyTask(), 0, 2000); } private class MyTask extends TimerTask{ @Override public void run() { Message message = new Message(); message.what = 1; handler.sendMessage(message); } } public void updateTitle(){ setTitle("Handle hello " + title); title ++; } }
