shaking / wobble view animation in android

You could try this:

shake.xml

<translate xmlns:android="http://schemas.android.com/apk/res/android" 
           android:fromXDelta="0" 
           android:toXDelta="10" 
           android:duration="1000" 
           android:interpolator="@anim/cycle_7" />

cycle_7.xml

<cycleInterpolator xmlns:android="http://schemas.android.com/apk/res/android" 
                   android:cycles="7" />

Try setting android:repeatMode="reverse". Below animation gives a very reasonable immitation on my Galaxy Nexus. Obviously you can fine tune the parameters to your own liking.

<?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="infinite"
    android:repeatMode="reverse"
    android:toDegrees="5" />

Nice shake animation;

res/anim/shake.xml

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

    <translate android:duration="150"
        android:fromXDelta="-10%"
        android:repeatCount="5"
        android:repeatMode="reverse"
        android:toXDelta="10%"/>
</set>

How to use it

final Animation animShake = AnimationUtils.loadAnimation(this, R.anim.shake);
btn_done = (Button) findViewById(R.id.btn_act_confirm_done); 
btn_done.startAnimation(animShake);

How to use it (Simpler version):

btn_done.startAnimation(AnimationUtils.loadAnimation(this,R.anim.shake));
