Create an animation from images in expansion APK

Question

So I want to create some animating ImageViews as described in :

http://developer.android.com/reference/android/graphics/drawable/AnimationDrawable.html

However I have been searching but couldn't find anything on this subject. Is it possible to have an item in the animation-list be an image inside an expansion APK file(a zip file). I already know how to get an image out of an Expansion APK file but I want to know if I can somehow get it into the animation-list, either programmatically or just referenced somehow in the XML file.

So my question is if this is possible? And (if possible) how I would go about doing this?

Answer 1

you can use different frame of image put in the drawable folder named first.png,second.png etc for animation effect and load it after certain interval of time.

create animation_list.xml and put it.

<?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/first" android:duration="210" />
    <item android:drawable="@drawable/second" android:duration="210" />
    <item android:drawable="@drawable/third" android:duration="210" />
    <item android:drawable="@drawable/fourth" android:duration="210" />
    <item android:drawable="@drawable/fifth" android:duration="210" />
    <item android:drawable="@drawable/sixth" android:duration="210" />

</animation-list>

Then in MainActivity code is.create imageview named yourImageView in the activity_main xml

import android.os.Bundle;
import android.app.Activity;
import android.graphics.drawable.AnimationDrawable;
import android.widget.ImageView;

public class MainActivity extends Activity {

    private AnimationDrawable frameAnimation;
    private ImageView view;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

        // Type casting the Image View
        view = (ImageView) findViewById(R.id.yourImageView);

        // Setting animation_list.xml as the background of the image view
        view.setBackgroundResource(R.drawable.animation_list);

        // Type casting the Animation drawable
        frameAnimation = (AnimationDrawable) view.getBackground();
        frameAnimation.start();
    }
}
