android - android 何时真正呈现并显示 Activity ？

Question

我试图了解 Android 操作系统在哪个阶段呈现布局，以便能够访问我的 ListView 中的 View 。谢谢

Answer 1

布局在 onCreate() 中创建:

The entire lifetime of an activity happens between the first call to onCreate(Bundle) through to a single final call to onDestroy().

Activity 从 onStart() 可见:

The visible lifetime of an activity happens between a call to onStart() until a corresponding call to onStop(). During this time the user can see the activity on-screen
