注意在 Mainfest 配置 Intent 

 

 

 

 

public class Loding extends Activity {

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

super.setContentView(R.layout.loding);

Timer timer = new Timer();

TimerTask task = new TimerTask() {

public void run() {

Intent intent = new Intent(Loding.this, MyActivityGroupDemo.class);

startActivity(intent);

Loding.this.finish();

}

};

timer.schedule(task, 1000 * 2);  （等待多少秒 跳转）

}

}
