如何设置片段的翻译动画

Question

我正在为应用程序中的片段事务使用自定义动画，但我在 gradle 中收到一个应用程序强制关闭此错误：

幻灯片动画.xml ：

<set xmlns:android="http://schemas.android.com/apk/res/android"
    android:shareInterpolator="false">
    <translate
        android:duration="700"
        android:fromXDelta="0%"
        android:fromYDelta="-100%"
        android:toXDelta="0%"
        android:toYDelta="0%" />
</set>

和滑出动画.xml：

<set xmlns:android="http://schemas.android.com/apk/res/android"
    android:shareInterpolator="false">
    <translate
        android:duration="700"
        android:fromXDelta="0%"
        android:fromYDelta="0%"
        android:toXDelta="0%"
        android:toYDelta="-100%" />
</set>

我该如何解决这个问题？

我找到了问题的答案。 对于片段，您应该在动画 XML 文件中使用 objectAnimator，如下所示：

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >
    <objectAnimator
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:duration="500"
        android:propertyName="yFraction"
        android:valueFrom="-1000"
        android:valueTo="0" />
</set>
