android - Android how to get image resource?

Question

I want to check if an imageview is displaying a certain image, how do I do that? Or maybe just if it has an image at all?

Answer 1

我建议使用 getDrawable() 方法：

Answer 2

   if(!yourImageView.getDrawable().equals(null)){
    // the View is displaying some image
     } else {
      //no image
     }
