</layout>

Вывод:

enter image description here

Я хочу управлять RadioButton нажатием клавиш CardView и RadioButton, я использовал следующий код:

/**
 * A simple {@link Fragment} subclass.
 */
public class FragmentListTransport extends Fragment implements View.OnClickListener {

    FragmentListOfTransportBinding mBinding;

    public FragmentListTransport() {
        // Required empty public constructor
    }


    @Override
    public View onCreateView(@NonNull LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        mBinding = DataBindingUtil.inflate(inflater, R.layout.fragment_list_of_transport, container, false);

        mBinding.parentCard1.setOnClickListener(this);
        mBinding.parentCard2.setOnClickListener(this);
        mBinding.parentCard3.setOnClickListener(this);
        mBinding.parentCard4.setOnClickListener(this);

        return mBinding.getRoot();
    }


    @Override
    public void onClick(View v) {

        switch (v.getId()) {
            case R.id.parent_card_1:
                mBinding.radioButton1.setChecked(true);
                mBinding.radioButton2.setChecked(false);
                mBinding.radioButton3.setChecked(false);
                mBinding.radioButton4.setChecked(false);
                break;
            case R.id.parent_card_2:
                mBinding.radioButton1.setChecked(false);
                mBinding.radioButton2.setChecked(true);
                mBinding.radioButton3.setChecked(false);
                mBinding.radioButton4.setChecked(false);
                break;
            case R.id.parent_card_3:
                mBinding.radioButton1.setChecked(false);
                mBinding.radioButton2.setChecked(false);
                mBinding.radioButton3.setChecked(true);
                mBinding.radioButton4.setChecked(false);
                break;
            case R.id.parent_card_4:
                mBinding.radioButton1.setChecked(false);
                mBinding.radioButton2.setChecked(false);
                mBinding.radioButton3.setChecked(false);
                mBinding.radioButton4.setChecked(true);
                break;
        }
    }
}

IsЕсть ли лучший способ справиться с этим?

У меня нет более простого пути, чем следовать (если у вас есть легкий путь, я его приму.):

/**
 * A simple {@link Fragment} subclass.
 */
public class FragmentListTransport extends Fragment implements View.OnClickListener {

    FragmentListOfTransportBinding mBinding;

    public FragmentListTransport() {
        // Required empty public constructor
    }


    @Override
    public View onCreateView(@NonNull LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        mBinding = DataBindingUtil.inflate(inflater, R.layout.fragment_list_of_transport, container, false);

        mBinding.parentCard1.setOnClickListener(this);
        mBinding.parentCard2.setOnClickListener(this);
        mBinding.parentCard3.setOnClickListener(this);
        mBinding.parentCard4.setOnClickListener(this);
        mBinding.radioButton1.setOnClickListener(this);
        mBinding.radioButton2.setOnClickListener(this);
        mBinding.radioButton3.setOnClickListener(this);
        mBinding.radioButton4.setOnClickListener(this);

        return mBinding.getRoot();
    }


    @Override
    public void onClick(View v) {

        switch (v.getId()) {
            case R.id.parent_card_1:
            case R.id.radio_button_1:
                clickedRadioButton(mBinding.radioButton1);
                break;
            case R.id.parent_card_2:
            case R.id.radio_button_2:
                clickedRadioButton(mBinding.radioButton2);
                break;
            case R.id.parent_card_3:
            case R.id.radio_button_3:
                clickedRadioButton(mBinding.radioButton3);
                break;
            case R.id.parent_card_4:
            case R.id.radio_button_4:
                clickedRadioButton(mBinding.radioButton4);
                break;
        }
    }

    private void clickedRadioButton(RadioButton radioButton) {
        mBinding.radioButton1.setChecked(false);
        mBinding.radioButton2.setChecked(false);
        mBinding.radioButton3.setChecked(false);
        mBinding.radioButton4.setChecked(false);

        radioButton.setChecked(true);
    }
}

Если у кого-то есть более простой способ, пожалуйста, оставьте ответ.Я приму.
