How to add fading TextView animation in Android

TextView is the basic building block of user interface components. It is used to set the text and display it to the user. It is a very basic component and used a lot. A Fading TextView is a TextView that changes its content automatically every few seconds. If we want to design a beautiful interface than we can use Fading TextView. Approach:

Add this to your root build.gradle file (not your module build.gradle file):

XML

allprojects {
    repositories {
           jcenter()
    }
}

Add the support Library in your module's build.gradle file and add dependency in the dependencies section.
XML
dependencies { implementation 'com.tomer:fadingtextview:2.5' }

Now add the following code in the activity_main.xml file.

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout 

    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

    <com.tomer.fadingtextview.FadingTextView
        android:id="@+id/fadingTextView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textSize="22sp"
        android:textColor="#2AC308"
        android:textStyle="bold"
        app:timeout="500"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

</androidx.constraintlayout.widget.ConstraintLayout>

Now add the following code in the MainActivity.java file.

MainActivity.java

package org.geeksforgeeks.gfgFadingTextView;

import androidx.appcompat.app.AppCompatActivity;
import android.os.Bundle;
import com.tomer.fadingtextview.FadingTextView;

public class MainActivity extends AppCompatActivity {

    FadingTextView fadingTextView;
    String[] text
        = { "GeeksForGeeks", "A",
            "Computer", "Science", "Portal",
            "For", "Geeks" };

    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        fadingTextView
            = findViewById(R.id.fadingTextView);
        fadingTextView.setTexts(text);
    }
}
