You want to start new activity. You can read more on initiating new Activities at Android documentation.
你想开始新的活动。您可以在Android 文档 中阅读有关启动新活动的更多信息。
However you might consider making a "normal" application screen and call another Activity for login purposes instead of having a login page and redirection.
但是，您可能会考虑制作一个“普通”应用程序屏幕并调用另一个 Activity 进行登录，而不是使用登录页面和重定向。
So if page/Activity_A requires user to be logged in, you call LoginActivitywith startActivityForResultand get true/false if user has properly logged in.
因此，如果 page/Activity_A 需要用户登录，您可以使用startActivityForResult调用LoginActivity并在用户正确登录时获取 true/false。

Read about Intents
阅读意图
intents are used to start new activity
意图用于开始新的活动
Activity is the super class that represents each of your view corresponding to your layout
Activity 是超类，代表您的布局对应的每个视图
in Professional Android App Dev- WROX by Retro Meier gives good examples for this in a chapter for Intents and Broadcast.
在 Retro Meier 的 Professional Android App Dev-WROX 中，在 Intents 和 Broadcast 一章中给出了很好的例子。
