How to get textview drawable resource id

I have an UI with some TextViews and I want to test if a textView has a certain drawable resource as background. I'm using the following code, but the tag is always null. 

Object tag = textView.getTag();
int backgroundId = R.drawable.bg_image_2;
if( tag != null && ((Integer)tag).intValue() == backgroundId) {
   //...do something...
}else{
   //...do something...
}

Which method returns the R.drawable background id number of an object? What am I doing wrong?

Tag is a feature for developer to save some object with Widget, you have use setTag() to save an arbitary object with UI widget. If you didn't setTag(), then getTag() would return NULL.

If the tag is null, it's because you didn't affect an Object to it with setTag
