Shows error when using LinearLayout instead of RelativeLayout

[tommygoh]

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 ?

What do you mean 'item_layout'?

[tommygoh]

@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]

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?
