android - view android的生命周期

Question

我希望在恢复我的 Activity 后出现一些 View 动画，但我无法在所有 View 加载之后成功捕捉到时间，并且动画在所有 View 加载之前(动画转换之前)开始。我尝试使用 onDraw、onWindowFocusChange、onResume，我发现 onDraw 是 View 生命周期的最后一个方法，但我仍然看到动画在用户看到所有 View 之前开始

这是在我的设备(Sony Z1 Compact)上测试的 Android Activity 生命周期和 Android View 生命周期

Start an Activity
    Activity: onCreate
    Activity: onStart
    Activity: onResume
    View: onAttachedToWindow
    View: onWindowFocusChanged true
    # Running
    Activity: onPause
    View: onWindowFocusChanged false
    # Start to another Activity
    # Back from another Activity
    Activity: onResume
    View: onWindowFocusChanged true
    # Running
    View: onWindowFocusChanged false
    Activity: onPause
    Activity: onStop
    Activity: onDestroy
    View: onDetachedFromWindow

Turn Off Screen
    Activity: onCreate
    Activity: onStart
    Activity: onResume
    View: onAttachedToWindow
    View: onWindowFocusChanged true
    # Running
    Activity: onPause
    Activity: onStop
    View: onWindowFocusChanged false
    # Turn Off Screen
    # Turn On Screen
    Activity: onStart
    Activity: onResume
    View: onWindowFocusChanged true
    # Running
    View: onWindowFocusChanged false
    Activity: onPause
    Activity: onStop
    Activity: onDestroy
    View: onDetachedFromWindow

Switch Application
    Activity: onCreate
    Activity: onStart
    Activity: onResume
    View: onAttachedToWindow
    View: onWindowFocusChanged true
    # Running
    Activity: onPause
    View: onWindowFocusChanged false
    Activity: onStop
    # Switch to Application
    # Back from Application
    Activity: onStart
    Activity: onResume
    View: onWindowFocusChanged true
    # Running
    Activity: onPause
    View: onWindowFocusChanged false
    Activity: onStop
    Activity: onDestroy
    View: onDetachedFromWindow
