我们可以看到,里面定义了接个控件和一个Animation，主要就是随机产生图片和文字,播放一段动画,挺简单的。

}

if (!isLogin()) {new WelcomeActivity.AsyncSetApprove().execute();isLogin = false;
} else {isLogin = true;
}

2.动画加载完后,发送消息给handler处理。相关代码

@Override
public void onAnimationEnd(Animation arg0) {isOK = true;//休眠1000毫秒new Thread(){public void run() {try {Thread.sleep(1000);} catch (InterruptedException e) {e.printStackTrace();}}}.start();//发送消息handler.sendEmptyMessage(2);
}

3.handler的handlerMessage中判断用户是不是第一次进入,并选择跳转界面

public void handleMessage(android.os.Message msg) {if (isLogin && isOK ) {if (isFristRun()) {// 如果是第一次启动程序则进入引导界面Intent intent = new Intent(WelcomeActivity.this,GuideActivity.class);startActivity(intent);} else {// 如果不是第一次启动则进入主页Intent intent = new Intent(WelcomeActivity.this,LodingActivity.class);startActivity(intent);}WelcomeActivity.this.finish();}}

// 判断是否是第一次启动程序private boolean isFristRun() {if (!isFirstRun) {return false;} else {editor.putBoolean("isFirstRun", false);editor.commit();return true;}}
