Creating a 3D flip animation in Android using XML

Question

I have created a 3D flip of a view using this android tutorial However, I have done it programmatically and I would like to do it all in xml, if possible. I am not talking about simply shrinking a view to the middle and then back out, but an actual 3D flip.

Is this possible via xml?

Answer 1

Here is the answer, though it only works with 3.0 and above.

1) Create a new resources folder called "animator".

2) Create a new .xml file which I will call "flipping". Use the following xml code:

<?xml version="1.0" encoding="utf-8"?>
<objectAnimator xmlns:android="http://schemas.android.com/apk/res/android"
    android:valueFrom="0" android:valueTo="360" android:propertyName="rotationY" >
</objectAnimator>

No, the objectAnimator tags do not start with an uppercase "O".

3) Start the animation with the following code:

ObjectAnimator anim = (ObjectAnimator) AnimatorInflater.loadAnimator(mContext, R.animator.flipping); 
anim.setTarget(A View Object reference goes here i.e. ImageView);
anim.setDuration(3000);
anim.start();

I got all this from here.
