from: https://developer.android.com/reference/android/content/res/XmlResourceParser.html
it said that: public interface XmlResourceParser implements AttributeSet XmlPullParser.
As it said, XmlResourceParser is an interface. and interface can’t implement interface imo.Only class can do that. Here the implement should be extends. is the document wrong? or i am wrong ? and where can i see the source code of XmlResourceParser?
There’s just an error in documentation. Check here for example and you’ll see that it extends AttributeSet.
