如何在Android中保持显示底部导航菜单标题？

<!-- activity_main.xml -->
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

    <!-- 主布局内容 -->

    <include
        layout="@layout/bottom_navigation_menu"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true" />

</RelativeLayout>

<!-- bottom_navigation_menu.xml -->
<com.google.android.material.bottomnavigation.BottomNavigationView
    android:id="@+id/bottom_navigation"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    app:menu="@menu/menu_bottom_navigation" />

<!-- menu_bottom_navigation.xml -->
<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <item
        android:id="@+id/navigation_item1"
        android:title="菜单项1"
        android:icon="@drawable/ic_item1" />
    <item
        android:id="@+id/navigation_item2"
        android:title="菜单项2"
        android:icon="@drawable/ic_item2" />
    <item
        android:id="@+id/navigation_item3"
        android:title="菜单项3"
        android:icon="@drawable/ic_item3" />
</menu>

// MainActivity.java
public class MainActivity extends AppCompatActivity {
    
    private BottomNavigationView bottomNavigationView;

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

        bottomNavigationView = findViewById(R.id.bottom_navigation);
        bottomNavigationView.setOnNavigationItemSelectedListener(new BottomNavigationView.OnNavigationItemSelectedListener() {
            @Override
            public boolean onNavigationItemSelected(@NonNull MenuItem item) {
                // 根据选中的菜单项做相应的处理
                switch (item.getItemId()) {
                    case R.id.navigation_item1:
                        // 处理菜单项1的点击事件
                        break;
                    case R.id.navigation_item2:
                        // 处理菜单项2的点击事件
                        break;
                    case R.id.navigation_item3:
                        // 处理菜单项3的点击事件
                        break;
                }
                return true;
            }
        });
    }
