如何设置片段的翻译动画？

Question

I am using a custom animation for Fragments transactions in my application but I get an application force close with this error in gradle:

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>

and 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>

How can I fix this?

I've found my questions answer. for fragments you should use objectAnimator in animation XML file like this:

<?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>
