My code is something like this

if(SlidingFragmentEN.isslidingshown){

                Log.e("isslidingshown",""+SlidingFragment.isslidingshownar);
                SlidingFragmentEN.isslidingshown =false;

// SlidingFragment.mLayout.setOverlayed(true);

                SlidingFragmentEN.mLayout.setPanelHeight(160);

                SlidingFragmentEN.mLayout.setParalaxOffset(30);
                SlidingFragmentEN.mLayout.setClipPanel(false);
            //  SlidingFragment.mLayout.setPanelState(PanelState.DRAGGING);
                SlidingFragmentEN.mLayout.setCoveredFadeColor(Color.argb(0, 0, 0, 0));
            }else{

                SlidingFragmentEN.isslidingshown =true;

                new ScaleInAnimation(categorybutton).animate();
                SlidingFragmentEN.mLayout.setParalaxOffset(0);
                SlidingFragmentEN.mLayout.setPanelHeight(0);
                SlidingFragmentEN.mLayout.setClipPanel(true);
                SlidingFragmentEN.mLayout.setCoveredFadeColor(Color.TRANSPARENT);

            }
