Answer 1

You can use this:

TextView myText = (TextView) findViewById(R.id.myText );  Animation anim = new AlphaAnimation(0.0f, 1.0f); anim.setDuration(50); //You can manage the blinking time with this parameter anim.setStartOffset(20); anim.setRepeatMode(Animation.REVERSE); anim.setRepeatCount(Animation.INFINITE); myText.startAnimation(anim); 

It's the same answer I gave in this post Blinking Text in android view

Hope this helps!

Use XML Animations for this purpose :

R.anim.blink

<?xml version="1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android">     <alpha android:fromAlpha="0.0"         android:toAlpha="1.0"         android:interpolator="@android:anim/accelerate_interpolator"         android:duration="600"         android:repeatMode="reverse"         android:repeatCount="infinite"/> </set> 

Blink Activity: use it like this :-

public class BlinkActivity extends Activity implements AnimationListener {      TextView txtMessage;     Button btnStart;      // Animation     Animation animBlink;      @Override     protected void onCreate(Bundle savedInstanceState) {         // TODO Auto-generated method stub         super.onCreate(savedInstanceState);         setContentView(R.layout.activity_blink);          txtMessage = (TextView) findViewById(R.id.txtMessage);         btnStart = (Button) findViewById(R.id.btnStart);          // load the animation         animBlink = AnimationUtils.loadAnimation(this,                 R.anim.blink);          // set animation listener         animBlink.setAnimationListener(this);          // button click event         btnStart.setOnClickListener(new View.OnClickListener() {              @Override             public void onClick(View v) {                 txtMessage.setVisibility(View.VISIBLE);                  // start the animation                 txtMessage.startAnimation(animBlink);             }         });      }      @Override     public void onAnimationEnd(Animation animation) {         // Take any action after completing the animation          // check for blink animation         if (animation == animBlink) {         }      }      @Override     public void onAnimationRepeat(Animation animation) {      }      @Override     public void onAnimationStart(Animation animation) {      }  }
