如何在单击列表项时从一个片段切换到另一个片段？

<FrameLayout
    android:id="@+id/fragment_container"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

public class Fragment1 extends Fragment {
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment1_layout, container, false);
        // 在这里可以对布局中的控件进行操作
        return view;
    }
}

public class Fragment2 extends Fragment {
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment2_layout, container, false);
        // 在这里可以对布局中的控件进行操作
        return view;
    }
}

public class MainActivity extends AppCompatActivity {
    private FragmentManager fragmentManager;
    private Fragment1 fragment1;
    private Fragment2 fragment2;

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

        fragmentManager = getSupportFragmentManager();
        fragment1 = new Fragment1();
        fragment2 = new Fragment2();

        // 默认显示第一个Fragment
        fragmentManager.beginTransaction()
                .add(R.id.fragment_container, fragment1)
                .commit();
    }

    public void onItemClick(View view) {
        // 切换到第二个Fragment
        fragmentManager.beginTransaction()
                .replace(R.id.fragment_container, fragment2)
                .commit();
    }
}
