Custom Animation Dialog with full screen

1.Extends AlertDialog class like this

public class CustomAnimationDialog extends AlertDialog {

    private AnimationDrawable mAnimation;

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

    public CustomAnimationDialog(Context context) {
        super(context,android.R.style.Theme_Translucent_NoTitleBar_Fullscreen);
    }

    private void replaceAnimation(){
        replaceAnimation(this.findViewById(R.id.animation));
    }

    private void replaceAnimation(View imageView){
        if(imageView == null){
            return ;
        }
        imageView.setBackgroundResource(R.drawable.custom_animation_for_progress);
        mAnimation = (AnimationDrawable) imageView.getBackground();
    }

    public static CustomAnimationDialog show(Context context, boolean cancelable) {
        CustomAnimationDialog dialog = new CustomAnimationDialog(context);
        dialog.setCancelable(cancelable);
        dialog.show();
        return dialog;
    }

    @Override
    public void show() {
        super.show();
        if(mAnimation != null) {
            mAnimation.start();
        }
    }

    @Override
    public void dismiss() {
        super.dismiss();
        if(mAnimation != null) {
            mAnimation.stop();
        }
    }
}

2.add layout,view_custom_progress_dialog.xml

    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"
    android:gravity="center"
    android:background="@android:color/transparent"
    >
    <ImageView
        android:id="@+id/animation"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:scaleType="centerCrop"
        android:adjustViewBounds="true"
        />
</LinearLayout>

3.add drawable animation PNG ,custom_animation_for_progress.xml

<animation-list xmlns:android="http://schemas.android.com/apk/res/android" android:oneshot="false">
    <item android:drawable="@drawable/animation_01" android:duration="250" />
    <item android:drawable="@drawable/animation_01_02" android:duration="250" />
    <item android:drawable="@drawable/animation_01_03" android:duration="250" />
