Android 喷气背包组件 - 在导航抽屉点击烤面包

Question

I am using navigation jetpack and have set up navigation drawer. Every thing works fine. But the problem is I want to show a toast when user clicks "nav_share" but it is not showing...

here is how i made navigation drawer

DrawerLayout drawer = findViewById(R.id.drawer_layout);
        NavigationView navigationView = findViewById(R.id.nav_view);

        navigationView.setNavigationItemSelectedListener(this);

        mAppBarConfiguration = new AppBarConfiguration.Builder(
                R.id.navigation_home, R.id.navigation_dashboard, R.id.navigation_plan, R.id.navigation_notifications)
                .setDrawerLayout(drawer)
                .build();

        NavController navController = Navigation.findNavController(this, R.id.nav_host_fragment);
        NavigationUI.setupActionBarWithNavController(this, navController, mAppBarConfiguration);
        NavigationUI.setupWithNavController(navigationView, navController);

my menu for navigation drawer is

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    tools:showIn="navigation_view">

    <group android:checkableBehavior="single">
        <item
            android:id="@+id/nav_home"
            android:icon="@drawable/ic_menu_camera"
            android:title="@string/menu_home" />
        <item
            android:id="@+id/nav_gallery"
            android:icon="@drawable/ic_menu_gallery"
            android:title="@string/menu_gallery" />
        <item
            android:id="@+id/nav_slideshow"
            android:icon="@drawable/ic_menu_slideshow"
            android:title="@string/menu_slideshow" />
        <item
            android:id="@+id/nav_tools"
            android:icon="@drawable/ic_menu_manage"
            android:title="@string/menu_tools" />
    </group>

    <item android:title="Communicate">
        <menu>
            <item
                android:id="@+id/nav_share"
                android:icon="@drawable/ic_menu_share"
                android:title="@string/menu_share" />
            <item
                android:id="@+id/nav_send"
                android:icon="@drawable/ic_menu_send"
                android:title="@string/menu_send" />
        </menu>
    </item>

</menu>

finally:

@Override
    public boolean onNavigationItemSelected(@NonNull MenuItem menuItem) {

        int id = menuItem.getItemId();

        if (id == R.id.nav_share)
            Toast.makeText(LauncherActivity.this, "Click", Toast.LENGTH_SHORT).show();

        DrawerLayout drawer = findViewById(R.id.drawer_layout);
        drawer.closeDrawer(GravityCompat.START);
        return true;
    }

I also had your problem and came up with the solution

NavController navController = Navigation.findNavController(this, R.id.nav_host_home);
    NavigationUI.setupWithNavController(navigationView, navController);

    navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
        @Override
        public boolean onNavigationItemSelected(@NonNull MenuItem menuItem) {
            int id = menuItem.getItemId();
            if (id == R.id.nav_share) {
                Toast.makeText(getApplicationContext(), "nav_share", Toast.LENGTH_SHORT).show();
            }
            NavigationUI.onNavDestinationSelected(menuItem, navController);
            drawerLayout.closeDrawer(Gravity.RIGHT);
            return true;
        }
    });
