Cool

Thanks.

It shows suggestion after second text, is there a way i can show all the results once user taps on the searchview ? In the debuggung, return new SuggestionsCursor(constraint) is not building the UI.

What is mPos in the code?

@kp96 I'm late but it's a member from AbstractCursor. I think you should use getPosition() instead.
