How to create bounce animation programmatically in Android

Issue #383

Right click res -> New -> Android Resource Directory, select anim and name it anim
Right click res/anim -> New -> Android Resource file, name it bounce

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate
        android:fromYDelta="0"
        android:toYDelta="-100"
        android:repeatCount="infinite" />
</set>
``` 

We have to set `repeatCount` in xml, setting in code does not work !!

```kt
val bounce = AnimationUtils.loadAnimation(context, R.anim.bounce)
bounce.repeatMode = Animation.REVERSE
bounce.duration = (1000..2000).random().toLong()

imageView.startAnimation(bounce)
