Creating animation on ImageView while changing image resource

by

For a single imageview you can use this helper function:

public static void ImageViewAnimatedChange(Context c, final ImageView v, final Bitmap new_image) {
    final Animation anim_out = AnimationUtils.loadAnimation(c, android.R.anim.fade_out); 
    final Animation anim_in  = AnimationUtils.loadAnimation(c, android.R.anim.fade_in); 
    anim_out.setAnimationListener(new AnimationListener()
    {
        @Override public void onAnimationStart(Animation animation) {}
        @Override public void onAnimationRepeat(Animation animation) {}
        @Override public void onAnimationEnd(Animation animation)
        {
            v.setImageBitmap(new_image); 
            anim_in.setAnimationListener(new AnimationListener() {
                @Override public void onAnimationStart(Animation animation) {}
                @Override public void onAnimationRepeat(Animation animation) {}
                @Override public void onAnimationEnd(Animation animation) {}
            });
            v.startAnimation(anim_in);
        }
    });
    v.startAnimation(anim_out);
}
