Hello @Alexinzaz ,
because the library needs to control the view's animation, the ScaleRatingBar needs a UI handler to process it.

so maybe you can not inflate view in not UI thread, or if you know any solution, please let me know.
Thanks for your help!

The view can post a runnable directly,not need new a Handler.
like this:
postDelayed(runnable,ANIMATION_DELAY);

after use "post" method,you can get handler object by method getHandler(),if you want to remove some runnable.
