SpashActivity三秒后进入主界面的用法

<div class="iteye-blog-content-contain" style="font-size: 14px">final Intent it = new Intent(this, MainActivity.class);

// 你要转向的Activity
Timer timer = new Timer();
TimerTask task = new TimerTask() {
@Override
public void run() {
startActivity(it); // 执行
finish();
}
};
timer.schedule(task, 1000 * 3); // 1秒后
}</div>

 注意finish，关掉欢迎界面了
