java - Multiple Navigation-Drawer Content onclick action -

have basic activity implemented custom toolbar&navigation drawer. had no problem until add buttons on main layout. assigned multiple drawer xml files under menu folder. problem is, when click toolbar hamburger icon, "r.menu.activity_main_drawer1" content coming correctly. when click on button on activity,, other menus comes too. problem starts there. having 2 issues on solutions. toolbar hamburger icon disappearing or menu contents not coming correctly.(when click on button first, "r.menu.activity_main_drawer2" coming right, after closing drawer, if click on toolbar menu, same "r.menu.activity_main_drawer2" appearing again.) hope explain. in advance.

public class index extends appcompatactivity implements view.onclicklistener{  protected void oncreate(bundle savedinstancestate) {      super.oncreate(savedinstancestate);     setcontentview(r.layout.index_p_activity);      button 1 = (button) findviewbyid(r.id.finans);     one.setonclicklistener(this);     button 2 = (button) findviewbyid(r.id.kayit);     two.setonclicklistener(this);      toolbar toolbar = (toolbar) findviewbyid(r.id.toolbar);     setsupportactionbar(toolbar);      drawerlayout drawer = (drawerlayout) findviewbyid(r.id.drawer_layout);      actionbardrawertoggle toggle = new actionbardrawertoggle(index_p.this, drawer, toolbar, "open", "close");     drawer.adddrawerlistener(toggle);     toggle.syncstate();       navigationview navigationview = (navigationview) findviewbyid(r.id.nav_view);     navigationview.getmenu().clear();     navigationview.inflatemenu(r.menu.activity_main_drawer1); }  @override public void onclick(view v) {      switch (v.getid()) {         case r.id.finans:     drawerlayout drawer = (drawerlayout) findviewbyid(r.id.drawer_layout);     actionbardrawertoggle toggle = new actionbardrawertoggle(index_p.this, drawer, toolbar, "open", "close");     drawer.adddrawerlistener(toggle);     toggle.syncstate();     navigationview navigationview = (navigationview) findviewbyid(r.id.nav_view);     navigationview.getmenu().clear();     navigationview.inflatemenu(r.menu.activity_main_drawer2);             break;     } }
