Here is my java code

if(view==btn_search)
        {
            //mActivity.pushFragments(com.media.contractcar.base.AppConstants.TAB_HOME, new NavigationDrawer(), true, true);
            // do your stuff
            //mActivity.pushFragments(com.media.contractcar.base.AppConstants.TAB_HOME, new SlideMenu(), true, true);


            Toast.makeText(mActivity, "Click on Search Button", Toast.LENGTH_LONG).show();

            // you need to get instance of relative layout in hide it 


            //v.findViewById(R.id.)

              ArrayAdapter<String> adapter = new ArrayAdapter<String>(mActivity, android.R.layout.simple_list_item_1, data);
             final DrawerLayout drawer = (DrawerLayout)v.findViewById(R.id.drawer_layout);
             final ListView navList = (ListView) v.findViewById(R.id.drawer);
             navList.setAdapter(adapter);
             navList.setOnItemClickListener(new OnItemClickListener(){
                     @Override
                     public void onItemClick(AdapterView<?> parent, View view, final int pos,long id)
                     {
                             drawer.setDrawerListener( new DrawerLayout.SimpleDrawerListener(){
                                     @SuppressLint("NewApi")
                                    @Override
                                     public void onDrawerClosed(View drawerView)
                                     {
                                            super.onDrawerClosed(drawerView);
                                        /*   AllDeals ad=new AllDeals();
                                           mActivity.pushFragments(com.media.contractcar.base.AppConstants.TAB_HOME, ad, true, true);*/


                                     }
                             });
                             drawer.closeDrawer(navList);
                     }
             });
        }
