How to set a pivot point while doing rotate animation using object animator in xml in Android?

Question

I am using property animation to rotate a fragment when it goes off screen. Following is my animator xml code:

<set xmlns:android="http://schemas.android.com/apk/res/android" >

<objectAnimator
    android:duration="500"
    android:propertyName="rotationY"
    android:valueFrom="-70"
    android:valueTo="0" >
</objectAnimator>
<objectAnimator
    android:duration="500"
    android:propertyName="alpha"
    android:valueFrom="0"
    android:valueTo="1" >
</objectAnimator>

I want to rotate with the central point of the left edge as the pivot. How to do this?

Answer 1

You can add the:

android:transformPivotX and
android:transformPivotY 

values to the object you want to animate in the layout XML where you created the object (Eg. android:transformPivotX="0dp")

Hope this helps!
