Recyclerview with radio group select only yes or no

Question

I have a recyclerview with two radio buttons in every row. One is for 'yes' and another for 'No'. I want to select only one radio button from each row at a time and get the value or the position of that radio button in an array list. In order to achieve single selection, I have enclosed these two radio buttons inside a Radio group. I need to set 'No' radio button in every row as active by default. Later, the user can select either 'Yes' or 'No' and the selected values should be stored in an ArrayList. How I achieve this.

here is my adapter code.

public class MyHealthInfoAdapter extends RecyclerView.Adapter<MyHealthInfoAdapter.MyHealthViewHolder> {

private Context context;
private ArrayList<DonorHealthStatusQuestionare> listQuestions;
private RadioButton lastCheckedRadioBtn = null;

private ArrayList<Integer> listYes = new ArrayList<>();
private ArrayList<Integer> listNo = new ArrayList<>();

private FloatingActionButton floatingActionButton;


public MyHealthInfoAdapter() {
}

public MyHealthInfoAdapter(Context context, ArrayList<DonorHealthStatusQuestionare> listQuestions) {
    this.context = context;
    this.listQuestions = listQuestions;
}

@Override
public MyHealthViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.rv_my_health_info, parent, false);
    return new MyHealthViewHolder(view);
}

@Override
public void onBindViewHolder(final MyHealthViewHolder holder, final int position) {

    final DonorHealthStatusQuestionare donorHealthStatusQuestionare = listQuestions.get(position);
    holder.tvQuestion.setText(donorHealthStatusQuestionare.getQuestions());

}

@Override
public int getItemCount() {
    return listQuestions.size();
}

public class MyHealthViewHolder extends RecyclerView.ViewHolder {

    CardView cvParent;
    TextView tvQuestion;
    RadioButton radioYes, radioNo;
    RadioGroup radioGroup;

    public MyHealthViewHolder(View itemView) {
        super(itemView);
        cvParent = itemView.findViewById(R.id.card_view_my_health_status_rv);
        tvQuestion = itemView.findViewById(R.id.tv_eligibility_question_my_info);
        radioYes = itemView.findViewById(R.id.radio_yes_my_health_info);
        radioNo = itemView.findViewById(R.id.radio_no_my_health_info);

        radioGroup = itemView.findViewById(R.id.my_health_status_check_group);


    }

}


}

And here is my recyclerview layout.

<android.support.v7.widget.CardView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/card_view_my_health_status_rv"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="1dp">

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:baselineAligned="false"
    android:orientation="horizontal"
    android:padding="12dp">

    <RelativeLayout
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_marginEnd="16dp"
        android:layout_marginRight="16dp"
        android:layout_weight="1">

        <TextView
            android:id="@+id/tv_eligibility_question_my_info"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" />

    </RelativeLayout>


    <RadioGroup
        android:orientation="horizontal"
        android:id="@+id/my_health_status_check_group"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_weight="0">

        <RadioButton
            android:id="@+id/radio_yes_my_health_info"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginEnd="16dp"
            android:layout_marginRight="16dp"
            android:text="@string/yes" />

        <RadioButton
            android:id="@+id/radio_no_my_health_info"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@string/no" />

    </RadioGroup>


</LinearLayout>

    radioGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
                @Override
                public void onCheckedChanged(RadioGroup group, int checkedId) {
                RadioButton rbbutton=(RadioButton)findViewByID(checkedId);
                if(rbbutton.getText().toString().equalsIgnoreCase("Yes")){
                 listYes.add(position)
                 }else{
                    listNo.add(position);
                 }
                }
            });

Code Snippet for make all unchecked :

for(int i=0;i<listQuestions.size();i++){
//do your logic here.
}

Where from this checkedId coming from. – Shibin Kalliatt Nov 25 '17 at 05:59
CheckID is id of selected radiobutton id. So, using it, you can create same radio button and access all property of that radio button. – Samir Bhatt Nov 25 '17 at 06:00
Ok got it. How to set all No as selected by default. – Shibin Kalliatt Nov 25 '17 at 06:05
add 1 for loop for list and set value – Samir Bhatt Nov 25 '17 at 06:05
Oh..I didn't get u please be specific – Shibin Kalliatt Nov 25 '17 at 06:08
Ok. Thank you so much brother. Let me implement this and update u. – Shibin Kalliatt Nov 25 '17 at 06:13
Sure let me know if you stuck anywhere – Samir Bhatt Nov 25 '17 at 06:14
