无法重写androidx.fragment.app.Dialog的onCreateDialog方法

import androidx.appcompat.app.AlertDialog;
import androidx.fragment.app.DialogFragment;

public class CustomDialogFragment extends DialogFragment {

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
        builder.setTitle("Custom Dialog")
                .setMessage("This is a custom dialog.")
                .setPositiveButton("OK", new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int id) {
                        // 点击确定按钮的逻辑处理
                    }
                })
                .setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int id) {
                        // 点击取消按钮的逻辑处理
                    }
                });
        return builder.create();
    }
}

CustomDialogFragment dialogFragment = new CustomDialogFragment();
dialogFragment.show(getSupportFragmentManager(), "custom_dialog");
