The application will always open the activity defined with the <category android:name="android.intent.category.LAUNCHER" /> intent-filter in the Manifest upon launch.应用程序将始终在启动时打开 Manifest 中使用<category android:name="android.intent.category.LAUNCHER" />意图过滤器定义的活动。 You'll likely want to swap your launch activity to be this new login page and implement some sort of navigation from the login to the main activity instead of vice versa.您可能希望将您的启动活动交换为这个新的登录页面，并实现从登录到主要活动的某种导航，而不是反之亦然。 While it is called the "MainActivity", the name itself doesn't carry any special privileges or functionality in the Android SDK.虽然它被称为“MainActivity”，但名称本身在 Android SDK 中没有任何特殊权限或功能。 It's just commonly associated with the launch intent filter.它通常与启动意图过滤器相关联。 Here I am assuming your login page is also an activity.在这里，我假设您的登录页面也是一项活动。 If this is not the case or you are unsure of how to navigate, I'm happy to help.如果不是这种情况，或者您不确定如何导航，我很乐意为您提供帮助。
