How to get textview drawable resource id

Issue

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?

Solution

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.
