    new Handler(new Callback() {

        @Override
        public boolean handleMessage(Message arg0) {
            // TODO Auto-generated method stub
            //做耗时操作
            startActivity(new Intent(getApplicationContext(),MainActivity.class));
            return false;
        }
    }).sendEmptyMessageDelayed(0, 3000);</code>

第二种方式：

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.welcome);
    //延时三秒进入主界面
    Timer timer = new Timer();
    timer.schedule(new Task(), 3000);
}

class Task extends TimerTask{

    @Override
    public void run() {
        // TODO Auto-generated method stub
        startActivity(new Intent(getApplicationContext(), MainActivity.class));
    }

}
