I think you can't, current API doesn't allow this. But if you really need this, you can do something like this:
我认为你不能,当前的 API 不允许这样做。但是如果你真的需要这个,你可以这样做:
imageButton.setImageResource(R.drawable.your_resource);
imageButton.setTag(R.drawable.your_resource);
//
// somewhere later...
//
Integer resource = (Integer)imageButton.getTag();
回答by Mokhefi Abdelkrim
You can use imageButton.getDrawable()
to get the drawable of the ImageButton object and then use setImageDrawable()
instead of setImageResource()
.
您可以使用imageButton.getDrawable()
获取 ImageButton 对象的可绘制对象,然后使用setImageDrawable()
代替setImageResource()
。

imageButton.setTag(R.drawable.your_resource);
Integer resource = (Integer) imageButton.getTag();
if(resource == R.drawable.your_resource){
// do something
}else {
