Repeat pulse Animation

Question

I'm trying to create a Infinite pulsing effect in a ImageView. But how is it possible to keep the offset?

<set xmlns:android="http://schemas.android.com/apk/res/android" android:shareInterpolator="false"> <scale     android:duration="700"     android:fromXScale="1"     android:fromYScale="1"     android:pivotX="50%"     android:pivotY="50%"     android:toXScale="0.5"     android:toYScale="0.5"/> <scale     android:duration="700"     android:fromXScale="1"     android:fromYScale="1"     android:pivotX="50%"     android:pivotY="50%"     android:startOffset="700"     android:toXScale="2"     android:toYScale="2"/> </set>

This will make your (Image)View pulsate up to 1.2 its size and back, repeatedly.

ImageView iv = (ImageView) findViewById(R.id.my_imageview);  ObjectAnimator scaleDown = ObjectAnimator.ofPropertyValuesHolder(                     iv,                     PropertyValuesHolder.ofFloat("scaleX", 1.2f),                     PropertyValuesHolder.ofFloat("scaleY", 1.2f)); scaleDown.setDuration(310);  scaleDown.setRepeatCount(ObjectAnimator.INFINITE); scaleDown.setRepeatMode(ObjectAnimator.REVERSE);  scaleDown.start();
