android如何将android导航项与片段进行通信(就像菜单一样)

public interface OnNavigationItemClickListener {
    void onNavigationItemClick(int itemId);
}

public class MainActivity extends AppCompatActivity implements OnNavigationItemClickListener {

    // ...

    @Override
    public void onNavigationItemClick(int itemId) {
        // 根据itemId执行相应的操作
        // 例如切换片段
    }

    // ...
}

public class MyFragment extends Fragment {

    private OnNavigationItemClickListener mListener;

    // ...

    @Override
    public void onAttach(@NonNull Context context) {
        super.onAttach(context);
        if (context instanceof OnNavigationItemClickListener) {
            mListener = (OnNavigationItemClickListener) context;
        } else {
            throw new RuntimeException(context.toString()
                    + " must implement OnNavigationItemClickListener");
        }
    }

    // 在需要通信的地方调用接口方法
    private void someMethod() {
        // ...
        mListener.onNavigationItemClick(itemId);
        // ...
    }

    // ...
}
