在没有RadioGroup的情况下管理RadioButton（单击ParentView）
我创建了一个包含4个CardView的XML，其中包含4个RadioButton和其他布局，如下所示：

输出：
我想同时点击RadioButton和CardView来管理RadioButton，我使用了以下代码：
/**
* 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;
}
}
}
是否有最佳的管理方式？

答案 0 :(得分：0)
然后，我不是最简单的方法（如果您有简单的方法，那么我会接受的。）：
/**
* 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);
}
}
如果有人最简单的方法，那么请发布答案。我会接受的。
