Hey. It's a great library but one thing. When i used Linear Layout for item_layout instead of RelativeLayout it crashed.

Am i missing something ? or the library can't use the linearlayout ?

turing-tech commented 7 years ago

What do you mean 'item_layout'?

tommygoh commented 7 years ago

@turing-tech sorry. what i mean is like this. when the recyclerview is in LinearLayout, it crashed, but when i use RelativeLayout it worked

turing-tech commented 7 years ago

That shouldn't mess it up. Anyway, this error suggests that the CustomIndicator class does not see itself as extending RelativeLayout, which its parent class does. Have you altered the library's code at all?
