Question

我想在恢复活动后发生一些视图动画，但是在加载所有视图并且在加载所有视图之前（动画转换之前）开始动画之后，我无法捕捉时间。我试图使用onDraw，onWindowFocusChange，onResume，我发现onDraw是视图生命周期中的最后一个方法，但我仍然看到动画在用户看到所有视图之前开始

Answer 1

除非视图具有生命周期，否则请考虑使用Fragment而不是视图作为片段。生命周期与它们嵌入的活动绑定。

另请参阅：What is the benefit of using Fragments in Android, rather than Views?

尝试延迟开始动画：

new Handler().post(new Runnable() { @Override public void run() { // Start your animation here. } });

这是Android Activity生命周期＆amp;在我的设备上测试的Android View生命周期（Sony Z1 Compact）

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

Answer 3

您可以创建启动活动。在此启动活动中，您可以显示动画。

如果您需要在显示动画时计算某事，请使用线程计算并将其发送到您的主要活动
