How To Animate a Button

We need a xml file that will define the Animation.

Create a folder named  "anim"  in res folder

Create a xml file named vanish.xml,  in this file we will define our Animation.

vanish.xml

<set xmlns:android="http://schemas.android.com/apk/res/android" >
   
<scale android:duration="300"     // duration in miliseconds
       android:fromXScale="1.0"    //  X scaling to start from
       android:fromYScale="1.0"    // Y scaling to start from
       android:toXScale="1.5"      
       android:toYScale="1.5"
       android:pivotX="40%"
       android:pivotY="40%"
       android:interpolator="@android:anim/decelerate_interpolator"/>
      

<alpha android:duration="300"
       android:fromAlpha="1.0"
       android:toAlpha="0.0"
       android:interpolator="@android:anim/decelerate_interpolator"/>
   
</set>


In your Activity class create the reference of the Button on which you want apply the animation.

Animation vanish =AnimationUtils.loadAnimation(this,R.anim.vanish);
findViewById(R.id.youButton).startAnimation(vanish).
