The names of my items are quite long, so I would like to make sure that their names scroll horizontally. I have searched on several SO posts, but I have not found a solution to my problem But I can't, I tried this:

My XML Menu:

<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_welcome"
        android:icon="@drawable/ic_folder_black_24dp"
        android:title="@string/menu_welcome" />
    <item
        android:id="@+id/nav_dataset1"
        android:icon="@drawable/ic_folder_black_24dp"
        android:title="@string/menu_dataset1"/>
    <item
        android:id="@+id/nav_dataset2"
        android:icon="@drawable/ic_folder_black_24dp"
        android:title="@string/menu_dataset2" />
    <item
        android:id="@+id/nav_dataset3"
        android:icon="@drawable/ic_folder_black_24dp"
        android:title="@string/menu_dataset3" />
</group>

My java :

private AppBarConfiguration mAppBarConfiguration;
private TextView tvDataset1;
private TextView tvDataset2;
private TextView tvDataset3;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_menu_deroulant);
    Toolbar toolbar = findViewById(R.id.toolbar);
    tvDataset1 = this.findViewById(R.id.nav_dataset1);
    tvDataset1.setSelected(true);
    setSupportActionBar(toolbar);
    DrawerLayout drawer = findViewById(R.id.drawer_layout);
    NavigationView navigationView = findViewById(R.id.nav_view);
    // Passing each menu ID as a set of Ids because each
    // menu should be considered as top level destinations.
    mAppBarConfiguration = new AppBarConfiguration.Builder(
            R.id.nav_dataset1, R.id.nav_dataset2, R.id.nav_dataset3)
            .setDrawerLayout(drawer)
            .build();
    NavController navController = Navigation.findNavController(this, R.id.nav_host_fragment);
    NavigationUI.setupActionBarWithNavController(this, navController, mAppBarConfiguration);
    NavigationUI.setupWithNavController(navigationView, navController);


}

But no change, does anyone have an idea ? Please help

EDIT :

I tried to override this :

<?xml version="1.0" encoding="utf-8"?>
<merge xmlns:android="http://schemas.android.com/apk/res/android">
 <CheckedTextView
    android:id="@+id/design_menu_item_text"
    android:layout_width="0dp"
    android:layout_height="match_parent"
    android:layout_weight="1"
    android:drawablePadding="@dimen/design_navigation_icon_padding"
    android:gravity="center_vertical|start"
    android:textAppearance="@style/TextAppearance.AppCompat.Body2"
    android:ellipsize="marquee"
    android:marqueeRepeatLimit="marquee_forever"
    android:scrollHorizontally="true"
    android:focusable="true"
    android:focusableInTouchMode="true"/>
 <ViewStub
    android:id="@+id/design_menu_item_action_area_stub"
    android:inflatedId="@+id/design_menu_item_action_area"
    android:layout="@layout/design_menu_item_action_area"
    android:layout_width="wrap_content"
    android:layout_height="match_parent" />
</merge>

I have some changes : AFTER the override:
