Deep copy of a Drawable

android imageview drawable

I have an ImageView. In its onClick I get its Drawable:

Drawable dr = ((ImageView) v).getDrawable();

And set it to a dialog's ImageView:

zoomedImage.setImageDrawable(dr);

But when I close the dialog or the activity is resumed. The image at the original position gets stretched and is shown larger than its size, leading to only a portion of the image is visible in the ImageView.

Is this a case of deep copy or there is another problem? If it is, how can do I deep copy the original Drawable so that I could set the copy to zoomed image?

Thanks in advance.

Finally I succeed! I had similar problem, when I used color filter on my drawable it changed the drawable, its very close to the solution of the other people here, but only this worked for me:

Drawable drwNewCopy = dr.getConstantState().newDrawable().mutate();
