android如何添加具有不同活动的相同片段

// Fragment类的定义
public class MyFragment extends Fragment {
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        // 定义片段的布局
        View view = inflater.inflate(R.layout.fragment_layout, container, false);
        // 可以在这里对布局中的控件进行操作和事件监听
        return view;
    }
}

// 活动中嵌入片段
public class MainActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // 实例化片段
        MyFragment fragment = new MyFragment();

        // 添加片段到活动
        FragmentManager fragmentManager = getSupportFragmentManager();
        FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
        fragmentTransaction.add(R.id.fragment_container, fragment);
        fragmentTransaction.commit();
    }
}
