如何在自定义对话框片段中切换布局(Android)

public class CustomDialogFragment extends DialogFragment {
    private boolean isLayout1 = true; // 初始布局标志位

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
        // 设置对话框的样式、标题等属性
        builder.setTitle("Custom Dialog");

        // 加载初始布局
        LayoutInflater inflater = getActivity().getLayoutInflater();
        View rootView = inflater.inflate(R.layout.layout1, null);
        builder.setView(rootView);

        // 添加切换布局按钮
        builder.setPositiveButton("Switch Layout", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                switchLayout();
            }
        });

        return builder.create();
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        // 加载初始布局
        return inflater.inflate(R.layout.layout1, container, false);
    }

    private void switchLayout() {
        // 切换布局
        if (isLayout1) {
            setView(R.layout.layout2);
        } else {
            setView(R.layout.layout1);
        }
        isLayout1 = !isLayout1;
    }

    private void setView(int layoutResId) {
        // 设置对话框的新布局
        LayoutInflater inflater = getActivity().getLayoutInflater();
        View rootView = inflater.inflate(layoutResId, null);
        getDialog().setContentView(rootView);
    }
}
