Cannot initialize ScollBar programmatically #121

Closed Antimonit closed 5 years ago

Antimonit commented 5 years ago

Calling non-XML constructor programmatically:

DragScrollBar(context, recyclerView, lightOnTouch)

results into an exception:

 Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'boolean android.content.res.TypedArray.hasValue(int)' on a null object reference
