Android NavigationView-Schublade schließt nicht

Question

Implementierung einer NavigationView-Schublade - Ich kann die Schublade erstellen und sehen, aber nicht mit Wischen schließen. Darüber hinaus scheint der NavigationItemSelectedListener nicht korrekt eingerichtet zu sein, da ich Click-Ereignisse auf den Elementen nicht erkennen kann.

MainActivity.java

private NavigationView navigationView; 
private DrawerLayout navDrawerLayout; 
private ListView navDrawerList; 
private ArrayList<NavDrawerItem> navDrawerItemList; 
private ActionBarDrawerToggle navDrawerToggle; 

    private void setupNavDrawer() { 
    this.navigationView = (NavigationView) findViewById(R.id.navigation_view); 
    navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() { 
     @Override 
     public boolean onNavigationItemSelected(MenuItem item) { 
      Utility.showDebugToast(String.valueOf(item.getItemId())); 
      if(item.isChecked()) { 
       item.setChecked(false); 
      } else { 
       item.setChecked(true); 
      } 
      navDrawerLayout.closeDrawers(); 
      return true; 
     } 
    }); 
    this.navDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout); 
    this.navDrawerList = (ListView) findViewById(R.id.left_drawer); 
    this.navDrawerItemList = new ArrayList<>(); 
    this.navDrawerItemList.add(new NavDrawerItem("NAME", NavDrawerItemType.NAME)); 
    this.navDrawerItemList.add(new NavDrawerItem("Create Mesh", NavDrawerItemType.CREATE_MESH)); 
    this.navDrawerList.setAdapter(new NavDrawerAdapter(this, R.layout.drawer_item, R.id.drawer_tab_text, this.navDrawerItemList)); 

    this.navDrawerToggle = new ActionBarDrawerToggle(this, navDrawerLayout, R.string.accept, R.string.accept) { 

     @Override 
     public void onDrawerClosed(View view) { 
      super.onDrawerClosed(view); 
     } 
     @Override 
     public void onDrawerOpened(View view) { 
      super.onDrawerOpened(view); 
     } 
    }; 

    this.navDrawerLayout.addDrawerListener(navDrawerToggle); 
    navDrawerToggle.syncState(); 
}

Warum kann nicht verrutschen ich die Schublade in die und aus?

Answer 1

In Bezug auf das Schubladenschließverhalten erwarte ich, dass dies mit der Struktur Ihres activity.xml zu tun hat.

Per the guidance here:

Um ein DrawerLayout zu verwenden, positionieren Sie die primäre Inhaltsansicht als erstes Kind mit einer Breite und Höhe von match_parent. Fügen Sie Schubladen als untergeordnete Ansichten nach der Hauptinhaltsansicht hinzu und legen Sie layout_gravity entsprechend fest.

Das ist also sagen, dass in Ihrem Fall, in dem Sie einen Inhaltsbereich und eine Schublade haben, sollte der DrawerLayout zwei Kinder hat; zuerst der Inhalt, dann die Schublade. In Ihrem Xml hat derzeit die DrawerLayout nur ein Kind, alles ist in der CoordinatorLayout.

Versuchen Sie, Ihre NavigationView außerhalb der CoordinatorLayout so Ihre Tätigkeit sieht wie folgt aus etwas bewegen:

<DrawerLayout> 
    <CoordinatorLayout> 
     content 
    </CoordinatorLayout> 

    <NavigationView> 
     drawer stuff 
    </NavigationView> 
</DrawerLayout>
