Simplest Blink Animation

Simplest blink animation for TextView. 
We have implemented blink animation as a result of infinitely repeated (in reverse mode) fade in animation. 
1. Create an animation resource for implementing fade-in animation.
blink_anim.xml

<?xml version="1.0" encoding="utf-8"?>
<alpha xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="200"
android:fromAlpha="0.0"
android:repeatCount="infinite"
android:repeatMode="reverse"
android:toAlpha="1.0" />

Code for setting animation to TextView in activity/fragment . Refer the TextView that need to be animated

TextView mTestTxv = (TextView) findViewById(R.id.testTxv);

Loading animation resource and setting it to the TextView

Animation mBlinkAnim = AnimationUtils.loadAnimation(this, R.anim.blink_anim);
mTestTxv.startAnimation(mBlinkAnim);
