Update Tick Count Programatically

[raghavsatyadev]

Reference Issue : #81

Seekbar generated from XML does not accept tick count programatically.

There is a method present IndicatorSeekBar#setTickCount( count ) , but it crashes the application.

@raghavsatyadev any crash log can you provide?

I tested the code again after firstly setting tick count to XML and then programatically changing it from Java, it worked. And to provide you the crash report I removed initial tick count property from the XML and only set it through Java.
