模拟器未切换到下一个活动

我对 Android 编程完全陌生。 我正在做一个简单的应用程序，其中显示启动屏幕，然后显示登录屏幕。问题是模拟器不会超出启动屏幕。 Android 清单：

我认为你在意图过滤器部分做错了 首先删除第二个活动中的意图过滤器代码并检查输出和评论

修改这一行

 Intent openLoginActivity = new  Intent("com.sanginfo.loginsample.LOGINACTIVITY");

as

 Intent openLoginActivity = new  Intent("Splash.this","LOGINACTIVITY.class");
