Question

我在我的应用程序中为Fragments事务使用自定义动画但是我在gradle中得到了一个关闭此错误的应用程序：

slideinanimation.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 slideoutanimation.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？

我发现我的问题回答了。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>

如何为片段设置翻译动画？
