如何在没有ActionBar的情况下在AndroidX中设置BottomNavigationView

<FrameLayout
    android:id="@+id/bottom_nav_container"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_gravity="bottom" />

FrameLayout bottomNavContainer = findViewById(R.id.bottom_nav_container);
BottomNavigationView bottomNavigationView = new BottomNavigationView(this);

bottomNavigationView.inflateMenu(R.menu.bottom_navigation_menu);
bottomNavigationView.setOnNavigationItemSelectedListener(new BottomNavigationView.OnNavigationItemSelectedListener() {
    @Override
    public boolean onNavigationItemSelected(@NonNull MenuItem item) {
        // 处理菜单项选中事件
        return true;
    }
});

bottomNavContainer.addView(bottomNavigationView);
