AndroidApps/ApplicationsMobile Development

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 = "http://schemas.android.com/apk/res/android"
   xmlns:tools = "http://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. To run the app from android studio, open one of your project's activity files and click Run   icon from the toolbar.
