Passing data From Activity to Fragment using interface [closed]

Answer 1

Activities contain fragments, you shouldn't need to pass anything. One technique would be to store your data in the activity scope and get a reference to it with getActivity().

Best practice to reference the parent activity of a fragment?

As far as the code you posted, I don't see where you call your pass data method within the fragment. I would suggest calling it in onviewcreated().

I will attempt to provide some sample code later as doing this on my mobile device is proving difficult.

Try passdata (getActivity ().someStringVariable);
