Android Beginner: Android Frames By Frames Animation

Step 1- Create a drawable folder.

Within it create an animation_list.xml file.
It includes :
A list of items that has the addresses of the frame images.

<?xml version="1.0" encoding="utf-8"?>

<animation-list xmlns:android="http://schemas.android.com/apk/res/android" android:oneshot="false">

<item android:drawable="@drawable/blank" android:duration="210" />

<item android:drawable="@drawable/logo" android:duration="210" />

<item android:drawable="@drawable/logo1" android:duration="210" />

<item android:drawable="@drawable/logo2" android:duration="210" />

<item android:drawable="@drawable/logo3" android:duration="210" />

<item android:drawable="@drawable/logo4" android:duration="210" />

<item android:drawable="@drawable/logo5" android:duration="210" />

<item android:drawable="@drawable/logo6" android:duration="210" />

<item android:drawable="@drawable/logofinal" android:duration="210" />

</animation-list>

Step 2- Create an activity_main.xml file

It Includes : An Image View

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

    xmlns:tools="http://schemas.android.com/tools"

    android:layout_width="match_parent"

    android:layout_height="match_parent" >

    <ImageView

        android:id="@+id/imageAnimation"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:adjustViewBounds="true" />

</RelativeLayout>

Here we are done with the xml part, see the image below for reference :-

Step 3- Outside the onCreate method :

Declare the Image View and Animation Drawable

// Declaring an Image View and an Animation Drawable

ImageView view;

AnimationDrawable frameAnimation;

Step4- Inside the OnCreate method:Typecast the Image view
Typecast the Animation Drawable
Set the drawable background on the image view

// Typecasting the Image View

view = (ImageView) findViewById(R.id.imageAnimation);

// Setting animation_list.xml as the background of the image view

view.setBackgroundResource(R.drawable.animation_list);

// Typecasting the Animation Drawable

frameAnimation = (AnimationDrawable) view.getBackground();

Step5- After the onCreate method :

The animation should only run when it is in focus that is when it is visible to the user. Hence define this method after the onCreate method.

// Called when Activity becomes visible or invisible to the user

@Override

public void onWindowFocusChanged(boolean hasFocus) {

    super.onWindowFocusChanged(hasFocus);

      if (hasFocus) {

    // Starting the animation when in Focus

    frameAnimation.start();

    } else {

        // Stoping the animation when not in Focus

    frameAnimation.stop();

      }

}

So the final result will look like this :-
