Make view bobbing like a teeter

We want a view move bobbing like a teeter.

Copy to below findViewByid.

final RotateAnimation rotate = new RotateAnimation(-10, 10, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);

rotate.setDuration(100);

rotate.setInterpolator(new LinearInterpolator());

rotate.setFillAfter(true);

rotate.setRepeatMode(Animation.REVERSE);       

rotate.setRepeatCount(Animation.INFINITE);           button.startAnimation(rotate);

If want it moving some time, change setRepeatCount to:

rotate.setRepeatCount(10);

Second way, in folder layout, create a file name bobbing.

<?xml version="1.0" encoding="utf-8"?>

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

    android:duration="100"

    android:fromDegrees="-5"

    android:pivotX="50%"

    android:pivotY="50%"

    android:repeatCount="10"

    android:repeatMode="reverse"

    android:toDegrees="5" />

In code, add this lines.

Animation bob = AnimationUtils.loadAnimation(this, R.drawable.bobbing);

image.startAnimation(bob);
