How to make Animate text from one TextView to another in Android?

This example demonstrate about How to make Animate text from one TextView to another.

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">
   <LinearLayout
      android:layout_width = "wrap_content"
      android:layout_height = "wrap_content">
      <LinearLayout
         android:id = "@+id/parent"
         android:layout_width = "wrap_content"
         android:layout_height = "wrap_content">
      <TextView
         android:id = "@+id/text"
         android:textSize = "30dp"
         android:textAlignment = "center"
         android:layout_width = "match_parent"
         android:textColor = "#ff4500"
         android:layout_height = "wrap_content"
         android:singleLine = "true" />
      </LinearLayout>
      <Button
         android:id = "@+id/animate"
         android:text = "Animated button"
         android:layout_width = "wrap_content"
         android:layout_height = "wrap_content" />
   </LinearLayout>
</RelativeLayout>

In the above code, we have taken text view and button, when user click on button, textview going to update

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

package com.example.andy.myapplication;

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.view.animation.Animation;
import android.view.animation.AnimationUtils;
import android.widget.Button;
import android.widget.LinearLayout;
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);
      final LinearLayout parent = findViewById(R.id.parent);
      view.setText("1+2");
      Button animate = findViewById(R.id.animate);
      animate.setOnClickListener(new View.OnClickListener() {
         @Override
         public void onClick(View v) {
            Animation slideUp = AnimationUtils.loadAnimation(getApplicationContext(), R.anim.slide_up);
            slideUp.setAnimationListener(new Animation.AnimationListener() {
               @Override
               public void onAnimationStart(Animation animation) {
               }
               @Override
               public void onAnimationEnd(Animation animation) {
                  view.setText("3");
               }
               @Override
               public void onAnimationRepeat(Animation animation) {
               }
            });
            parent.startAnimation(slideUp);
         }
      });
   }
}

Let's try to run your application. I assume you have connected your actual Android Mobile device with your computer.
