How to add fading TextView animation in Android
  • Difficulty Level : Medium
  • Last Updated : 23 Feb, 2021

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:

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




    allprojects {
        repositories {
               jcenter()
        }
    }
  2. Add the support Library in your module’s build.gradle file and add dependency in the dependencies section.






    dependencies {
        implementation 'com.tomer:fadingtextview:2.5'
    }
  3. 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: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>

  4. 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);
        }
    }
