NavigationView OnNavigationItemSelectedListener n'est pas appelé

J'essaie d'utiliser NavigationView à partir de Android Support Library de conception dans mon application. Pour une raison quelconque, OnNavigationItemSelected l'écouteur n'est pas appelé. Voici mon code

Lorsque vous faites une mise en page XML, vous devez écrire NavigationView après BaseLayout (FrameLayout, LinearLayout, etc.)

<DrawerLayout>
    <FrameLayout />
    <NavigationView />
</DrawerLayout>

Pour moi, cela a fait l'affaire!

navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.bringToFront();

La disposition principale de votre activité devrait ressembler à ceci:

<Android.support.v4.widget.DrawerLayout
    xmlns:Android="http://schemas.Android.com/apk/res/Android"
    xmlns:app="http://schemas.Android.com/apk/res-auto"
    Android:id="@+id/navigationDrawer"
    Android:layout_width="match_parent"
    Android:layout_height="match_parent">

    <include layout="@layout/activity_main_content" />

    <Android.support.design.widget.NavigationView
        Android:id="@+id/navigationView"
        style="@style/NavigationView"
        Android:layout_width="wrap_content"
        Android:layout_height="match_parent"
        Android:layout_gravity="right"
        app:headerLayout="@layout/header"
        app:menu="@menu/menu_drawer"/>

</Android.support.v4.widget.DrawerLayout>

Dans cette NavigationView j'ai lié header.xml et menu_drawer.xml (à partir du dossier menu) par exemple menu_drawer.xml:

<menu xmlns:Android="http://schemas.Android.com/apk/res/Android">
        <group Android:checkableBehavior="single">
            <item
                Android:id="@+id/nav1"
                Android:checked="true"
                Android:icon="@drawable/logo"
                Android:title="Navigation item 1"/>
            <item
                Android:id="@+id/nav2"
                Android:icon="@drawable/logo"
                Android:title="Navigation item 2"/>
        </group>
    </menu>

que votre Java:

public class ActivityMain extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener {

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        setUpToolbar();
        setUpNavDrawer();
    }

 private void setUpNavDrawer() {
        NavigationView view = (NavigationView) findViewById(R.id.navigationView);
        mDrawerLayout = (DrawerLayout) findViewById(R.id.navigationDrawer);
        view.setNavigationItemSelectedListener(this);
        mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, toolbar, R.string.drawerOpen, R.string.drawerClose);
        mDrawerLayout.addDrawerListener(mDrawerToggle);
        mDrawerToggle.syncState();
    }

Vérifiez si cela fonctionne pour vous. Dans mon projet fonctionne comme un charme.
