4 个解决方案

You want to start new activity . 你想开始新的活动。 You can read more on initiating new Activities at Android documentation . 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，您可以考虑创建一个“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 LoginActivity with startActivityForResult and get true/false if user has properly logged in. 因此，如果page / Activity_A要求用户登录，则使用startActivityForResult调用LoginActivity ，如果用户已正确登录，则获取true / false。

create an Intent and pass the intent to startactivty method. 创建一个Intent并将intent传递给startactivty方法。 ake sure your activity should be defined in manifest file 确保您的活动应在清单文件中定义

Read about Intents 阅读Intents

intents are used to start new activity 意图用于开始新活动

Activity is the super class that represents each of your view corresponding to your layout Activity是表示与布局对应的每个视图的超类
