MenuItem 클릭에 대한 참조는 어떻게받을 수 있습니까?

Question

문제가 있습니다. 내 DrawerLayot 내 ListView 참조를 얻는 방법을 모르겠습니다.

NavigationView 및 메뉴가있는 drawerLayout이 있습니다.

내가 클릭 할 때 어떻게 레이아웃을 표시 할 수 있습니까?

navView = (NavigationView) findViewById(R.id.nav_view); 
View navHeader = navView.getHeaderView(0); 
TextView usuario_header = (TextView) navHeader.findViewById(R.id.username); 
TextView correo_header = (TextView) navHeader.findViewById(R.id.emailNavegador); 

layout del activity_principal.

<?xml version="1.0" encoding="utf-8"?> <android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:app="http://schemas.android.com/apk/res-auto"

탐색 서랍에서 메뉴 항목을 클릭의 참조를 얻으려면, 당신은이 방법

navView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() { 
      @Override 
      public boolean onNavigationItemSelected(@NonNull MenuItem item) { 
       switch(item.getItemId()){ 

        case R.id.nav_noticias: 

        Toast.makeText(getApplicationContext(),"Noticias",Toast.LENGTH_SHORT).show; 

        break; 

        case R.id. nav_sesion: 

        Toast.makeText(getApplicationContext(),"nav_sesion",Toast.LENGTH_SHORT).show; 

        break; 

        ...... 

       } 


       return false; 
      } 
     }); 

이 당신이 탐색 메뉴에서 클릭 이벤트를 달성하는 방법입니다 ..
