How to make count animation in Android TextView?

This example demonstrate about How to make count animation in Android TextView.

Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.

Step 2 − Add the following code to res/layout/activity_main.xml.

<?xml version = "1.0" encoding = "utf-8"?>
<RelativeLayout
   xmlns:android = "https://schemas.android.com/apk/res/android"
   xmlns:tools = "https://schemas.android.com/tools"
   android:layout_width = "match_parent"
   android:gravity = "center"
   android:layout_height = "match_parent">
   <TextView
      android:id = "@+id/text"
      android:textSize = "20dp"
      android:textAlignment = "center"
      android:layout_width = "match_parent"
      android:textColor = "#ff4500"
      android:layout_height = "wrap_content"
      android:singleLine = "true" />
</RelativeLayout>

In the above code, we have taken text view to show count animation from 0 to 100.

Step 3 − Add the following code to src/MainActivity.java

package com.example.andy.myapplication;
import android.animation.ValueAnimator;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.widget.TextView;

public class MainActivity extends AppCompatActivity {
   @Override
   protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
      final TextView view = findViewById(R.id.text);
      ValueAnimator animator = new ValueAnimator();
      animator.setObjectValues(0, 100);
      animator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
         public void onAnimationUpdate(ValueAnimator animation) {
            view.setText(String.valueOf(animation.getAnimatedValue()));
         }
      });
      animator.setDuration(10000); // here you set the duration of the anim
      animator.start();
   }
}

To get count animation use the following code -

ValueAnimator animator = new ValueAnimator();
animator.setObjectValues(0, 100);
animator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
   public void onAnimationUpdate(ValueAnimator animation) {
      view.setText(String.valueOf(animation.getAnimatedValue()));
   }
});
animator.setDuration(10000);
animator.start();

In the above code, it starts from 0 to 100 with 1000ms time interval.

Let's try to run your application. I assume you have connected your actual Android Mobile device with your computer. To run the app from android studio, open one of your project's activity files and click Run  icon from the toolbar. Select your mobile device as an option and then check your mobile device which will display your default screen −

In the above result, it will change the text with count animation.
