Android在支持v4 jar文件的片段之间翻转动画

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。因为我想实现较低版本的片段。我找到了用于翻转动画的android。但是支持的库不支持对象动画。搜索internet后，我发现我需要将对象动画更改为。如何将这些xml文件更改为tween动画吼叫

我更改了这些xml文件，但它对我们不起作用。有人能解释一下我的错误吗？请帮助我共享完整的教程和其他资源。有人能为我提供正确的tween动画吗？

如果“Objacter Animation”是指ObjectAnimator，那么兼容性库不支持它。相反，您应该看一看NineodelDroid库，它将蜂巢+动画API引入了较旧的平台：

  <!-- 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. -->
