嗨,我将使用支持的 jar 文件在 android 中开发片段事务之间的翻转动画。因为我想为较低版本实现片段。我找到了翻转动画的 android开发者教程。但是支持的库不支持Objactor 动画。搜索互联网后我发现我需要将 objacter 动画更改为Tween 动画. .如何将这些 xml 文件更改为像下面这样的补间动画。
card_flip_left_in.xml
<!-- Before rotating, immediately set the alpha to 0. -->
<alpha
android:valueFrom="1.0"
android:valueTo="0.0"
android:propertyName="alpha"
android:duration="0" />
<!-- Rotate. -->
<rotate
android:valueFrom="-180"
android:valueTo="0"
android:propertyName="rotationY"
android:interpolator="@android:anim/accelerate_decelerate_interpolator"
android:duration="@integer/card_flip_time_full"/>
<!-- Half-way through the rotation (see startOffset), set the alpha to 1. -->
<alpha
android:valueFrom="0.0"
android:valueTo="1.0"
android:propertyName="alpha"
android:startOffset="@integer/card_flip_time_half"
android:duration="1" />
card_flip_left_out.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >
<!-- Rotate. -->
<rotate
android:duration="@integer/card_flip_time_full"
android:interpolator="@android:anim/accelerate_decelerate_interpolator"
android:propertyName="rotationY"
android:valueFrom="0"
android:valueTo="180" />
<!-- Half-way through the rotation (see startOffset), set the alpha to 0. -->
<alpha
android:duration="1"
android:propertyName="alpha"
android:startOffset="@integer/card_flip_time_half"
android:valueFrom="1.0"
android:valueTo="0.0" />
</set>
card_flip_right_in.xml
<!-- Before rotating, immediately set the alpha to 0. -->
<alpha
android:duration="0"
android:propertyName="alpha"
android:valueFrom="1.0"
android:valueTo="0.0" />
<!-- Rotate. -->
<rotate
android:duration="@integer/card_flip_time_full"
android:interpolator="@android:anim/accelerate_decelerate_interpolator"
android:propertyName="rotationY"
android:valueFrom="180"
android:valueTo="0" />
<!-- Half-way through the rotation (see startOffset), set the alpha to 1. -->
<alpha
android:duration="1"
android:propertyName="alpha"
android:startOffset="@integer/card_flip_time_half"
android:valueFrom="0.0"
android:valueTo="1.0" />
</set>
card_flip_right_out.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >
<!-- Rotate. -->
<rotate
android:duration="@integer/card_flip_time_full"
android:interpolator="@android:anim/accelerate_decelerate_interpolator"
android:propertyName="rotationY"
android:valueFrom="0"
android:valueTo="-180" />
<!-- Half-way through the rotation (see startOffset), set the alpha to 0. -->
<alpha
android:duration="1"
android:propertyName="alpha"
android:startOffset="@integer/card_flip_time_half"
android:valueFrom="1.0"
android:valueTo="0.0" />
</set>
我更改了那些 xml 文件,但它对我们不起作用..任何人都可以解释我做错了什么。请帮助我分享使用完整教程和其他资源..任何人都可以为我提供正确的补间动画对于那些 。
