View Android的生命周期 [英] Life cycle of view android

问题描述

我希望在恢复活动后出现一些视图动画，但是我无法成功地捕捉到所有视图加载完毕并且动画开始于所有视图加载之前的时间(在动画过渡之前). 我尝试使用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就开始了

I want some view animation to occur after resuming my activity, but I can't succeed to catch the time after all the views loaded and the animation started before all the views loaded (before the animation transition). i tried to use onDraw, onWindowFocusChange, onResume, I discovered that onDraw is the last method on the life cycle of view but I still saw that the animation start before the user see the all the views

推荐答案

这是Android Activity生命周期& Android View生命周期已在我的设备(Sony Z1 Compact)上进行了测试

Here is Android Activity lifecycle & Android View lifecycle tested on my device (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
