mainactivity.java :

if(position!=0){  linearlayout.layoutparams lp = new linearlayout.layoutparams(0,0,0);     // framelayout child of linearlayout    getsupportfragmentmanager().findfragmentbyid(r.id.frame_container_slider).getview().setlayoutparams(lp);         }

please change main activity code bellow code.

if (position != 0) {     framelayout.layoutparams lp = new framelayout.layoutparams(0,0,0);     getsupportfragmentmanager().findfragmentbyid(r.id.frame_container_slider)                                .getview()                                .setlayoutparams(lp); }
