如何设置从活动重定向后的特定BottomNavigation菜单片段

public class YourActivity extends AppCompatActivity {
    private BottomNavigationView bottomNavigationView;

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

        bottomNavigationView = findViewById(R.id.bottom_navigation_view);
        bottomNavigationView.setOnNavigationItemSelectedListener(new BottomNavigationView.OnNavigationItemSelectedListener() {
            @Override
            public boolean onNavigationItemSelected(@NonNull MenuItem item) {
                switch (item.getItemId()) {
                    case R.id.menu_item1:
                        // 加载并显示特定的Fragment
                        Fragment1 fragment1 = new Fragment1();
                        getSupportFragmentManager().beginTransaction()
                                .replace(R.id.fragment_container, fragment1)
                                .commit();
                        return true;
                    case R.id.menu_item2:
                        // 加载并显示特定的Fragment
                        Fragment2 fragment2 = new Fragment2();
                        getSupportFragmentManager().beginTransaction()
                                .replace(R.id.fragment_container, fragment2)
                                .commit();
                        return true;
                    // 添加其他菜单项的处理逻辑
                }
                return false;
            }
        });
    }
}
