Recycler view issue in Umano AndroidSlidingPanel

Question

i am using this AndroidSlidingUpPanel .

My main content is Map and second one which slide up panel is Recyclerview . But Issue is it not coming on panel size correctly.

On Collapsed State : its coming correctly but as soon as i drag up and expanded State it shows the orange color bar like thing at end . Orange color is due to the background set in linear Layout which is the host of RcycleView . If we remove the background then also problem stays which THE BAR LIKE THING AT END OF RECYCLER VIEW LIST .

I want : Recycler view to be show as same height as Panel . No linear layout shown at end of it .

I think i did something wrong in placing views in XML . But i didn't able to understand what .

Collapsed PanelState

EXPANDED STATE
