我做了一个自定义动画主题（滑动向上和向下滑动）。 动画工作正常，上了年纪的Andr​​oid版本.. 然而，当我尝试它在Android 4.0（ICS）上的关闭动画不起作用。只有向上滑动动画正常工作的ICS。

I made a theme with a custom animation (slide up and slide down). The animation works fine on the older android versions.. However, when I try it out on Android 4.0 (ICS) the on close animation doesn't work. Only the slide up animation works fine on ICS.

下面是我的主题我使用的动画：

Here is my theme I use for the animation:

<style name="myTheme" parent="android:Theme.Black">
    <item name="android:windowTitleSize">45dip</item>
    <item name="android:windowTitleBackgroundStyle">@style/CustomWindowTitleBackground</item>
    <item name="android:windowAnimationStyle">@style/myTheme.Window</item>
</style>

<style name="myTheme.Window" parent="@android:style/Animation.Activity">
    <item name="android:activityOpenEnterAnimation">@anim/push_up_in_no_alpha</item>
    <item name="android:activityOpenExitAnimation">@anim/no_anim</item>
    <item name="android:activityCloseEnterAnimation">@anim/no_anim</item>
    <item name="android:activityCloseExitAnimation">@anim/push_down_out_no_alpha</item>
</style>

这里是 push_down_out_no_alpha.xml

<set xmlns:android="http://schemas.android.com/apk/res/android">
        <translate android:fromYDelta="0" android:toYDelta="100%p"
        android:duration="@android:integer/config_longAnimTime"/>
</set>

当我设置$ C $一个动画C中，它也能正常工作的ICS，但为什么不作为一个主题？

When i set a animation in code it also works fine on ICS, but why not as a theme?

 this.overridePendingTransition(R.anim.no_anim,R.anim.push_down_out_no_alpha);

有谁知道为什么它不工作在Android 4.0（ICS）？

Does anyone know why it isn't working on Android 4.0 (ICS)?

推荐答案

从清单中指定的动画似乎在ICS :-(破 覆盖动画解决方案正常工作，但你可能不希望硬$ C C动画$。这将是很好的表现让他们，你会为其他平台版本的..所以......

Specifying animations from the manifest appears to be broken in ICS :-( The override animation solution works fine, but you probably don't want to hard-code the animations. It would be nice to get them from the manifest as you would for other versions of the platform.. so....

添加几个成员字段到你的活动举行动画的ID连接到你的活动。

add a couple of member fields to your activity to hold the ids of the animations attached to your activity..

protected int activityCloseEnterAnimation;
protected int activityCloseExitAnimation;

和地方在您的onCreate ...

and somewhere in your onCreate...

// Retrieve the animations set in the theme applied to this activity in the
// manifest..
TypedArray activityStyle = getTheme().obtainStyledAttributes(new int[] {android.R.attr.windowAnimationStyle});
int windowAnimationStyleResId = activityStyle.getResourceId(0, 0);      
activityStyle.recycle();

// Now retrieve the resource ids of the actual animations used in the animation style pointed to by 
// the window animation resource id.
activityStyle = getTheme().obtainStyledAttributes(windowAnimationStyleResId, new int[] {android.R.attr.activityCloseEnterAnimation, android.R.attr.activityCloseExitAnimation});
activityCloseEnterAnimation = activityStyle.getResourceId(0, 0);
activityCloseExitAnimation = activityStyle.getResourceId(1, 0);
activityStyle.recycle();

那么无论你的活动结束/应适用的动画包括...

then wherever your activity finishes/should apply animation include...

overridePendingTransition(activityCloseEnterAnimation, activityCloseExitAnimation);

和你的活动应该正确地履行你的主题/样式连接到活动中的表现进行设置。动画

and your activities should correctly honour the animations you set in the theme/style attached to activities in your manifest.
