In xml file your image have not android:src="" and android:backgroud=""

   if(null!=imgView.getDrawable())
     {
        //imageview has image
     }else{
       //imageview has no image  
     }

Despite what the accepted answer proposes, you should do the following instead:

publie static boolean hasNullOrEmptyDrawable(ImageView iv)
{
    Drawable drawable = iv.getDrawable();
    BitmapDrawable bitmapDrawable = drawable instanceof BitmapDrawable ? (BitmapDrawable)drawable : null;

    return bitmapDrawable == null || bitmapDrawable.getBitmap() == null;
}

See explanation in my previous answer.
