How to create a blinking text in Android?

Here I am explaining two methods on how to create a blinking textview in Android.

One with the help of Animation class and other with a Logic.

package com.example.blinktext;

 

import android.app.Activity;

import android.os.Bundle;

import android.os.Handler;

import android.view.Menu;

import android.view.View;

import android.view.animation.AlphaAnimation;

import android.view.animation.Animation;

import android.widget.TextView;

 

public class MainActivity extends Activity {

 

    @Override

    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

        blinkText();

        //blinkText2();

    }

     

    private void blinkText(){

        final Handler handler = new Handler();

        new Thread(new Runnable() {

            @Override

            public void run() {

            int timeToBlink = 1000;    //in ms

            try{

                Thread.sleep(timeToBlink);

            }catch (Exception e) {

                 

            }

            handler.post(new Runnable() {

                @Override

                    public void run() {

                    TextView txt = (TextView) findViewById(R.id.tv);

                    if(txt.getVisibility() == View.VISIBLE){

                        txt.setVisibility(View.INVISIBLE);

                    }else{

                        txt.setVisibility(View.VISIBLE);

                    }

                    blinkText();

                }

                });

            }}).start();

   }

     

    public void blinkText2(){

        TextView myText = (TextView) findViewById(R.id.tv );

 

        Animation anim = new AlphaAnimation(0.0f, 1.0f);

        anim.setDuration(50); //You can manage the time of the blink with this parameter

        anim.setStartOffset(20);

        anim.setRepeatMode(Animation.REVERSE);

        anim.setRepeatCount(Animation.INFINITE);

        myText.startAnimation(anim);

    }   

 

    @Override

    public boolean onCreateOptionsMenu(Menu menu) {

        getMenuInflater().inflate(R.menu.activity_main, menu);

        return true;

    }    

}
