自定义窗口进入动画：

Animation Resources xml动画资源语法：[https://developer.android.google.cn/guide/topics/resources/animation-resource\#translate-element][https_developer.android.google.cn_guide_topics_resources_animation-resource_translate-element]

在xml中定义View animation，文件名为floating\_window\_enter.xml：

起始Y坐标为fromYDelta\*0.01\*view.mTop+view.mTop，动画结束的Y坐标为toYDelta\*0.01\*view.mTop+view.mTop

自定义style，使窗口属性指向floating\_window\_enter：

在添加窗口时加入R.style.floating\_enter:

lp.windowAnimations=R.style.floating_enter;

Animation View的语法如下：

<?xml version="1.0" encoding="utf-8"?>
    <set xmlns:android="http://schemas.android.com/apk/res/android"
        android:interpolator="@[package:]anim/interpolator_resource"
        android:shareInterpolator=["true" | "false"] >
        <alpha
            android:fromAlpha="float"
            android:toAlpha="float" />
        <scale
            android:fromXScale="float"
            android:toXScale="float"
            android:fromYScale="float"
            android:toYScale="float"
            android:pivotX="float"
            android:pivotY="float" />
        <translate
            android:fromXDelta="float"
            android:toXDelta="float"
            android:fromYDelta="float"
            android:toYDelta="float" />
        <rotate
            android:fromDegrees="float"
            android:toDegrees="float"
            android:pivotX="float"
            android:pivotY="float" />
        <set>
            ...
        </set>
    </set>

与窗口动画相关的属性如下：

<declare-styleable name="WindowAnimation">
            
            <attr name="windowEnterAnimation" format="reference" />

            <attr name="windowShowAnimation" format="reference" />
            
            <attr name="windowHideAnimation" format="reference" />
    
            
            <attr name="activityOpenEnterAnimation" format="reference" />
            
            <attr name="activityOpenExitAnimation" format="reference" />
            
            <attr name="activityCloseEnterAnimation" format="reference" />
            
            <attr name="activityCloseExitAnimation" format="reference" />

            <attr name="launchTaskBehindSourceAnimation" format="reference" />
            
            <attr name="taskCloseEnterAnimation" format="reference" />
            
            <attr name="taskCloseExitAnimation" format="reference" />
            
            <attr name="taskToFrontEnterAnimation" format="reference" />
            
            <attr name="taskToFrontExitAnimation" format="reference" />
            
            <attr name="taskToBackEnterAnimation" format="reference" />
            
            <attr name="taskToBackExitAnimation" format="reference" />

            <attr name="wallpaperOpenExitAnimation" format="reference" />
            
            <attr name="wallpaperCloseEnterAnimation" format="reference" />
            
            <attr name="wallpaperCloseExitAnimation" format="reference" />
    
            
            <attr name="wallpaperIntraOpenEnterAnimation" format="reference" />
            
            <attr name="wallpaperIntraOpenExitAnimation" format="reference" />
            
            <attr name="wallpaperIntraCloseEnterAnimation" format="reference" />
            
            <attr name="wallpaperIntraCloseExitAnimation" format="reference" />
    
            
            <attr name="activityOpenRemoteViewsEnterAnimation" format="reference" />
    
        </declare-styleable>
