How I can select Radio button When I Long click On any place on item if I am using recyclerview

Question

I'm having trouble with select Radio button within a RecyclerView when I long click on Item

At the moment, I've set up up the RecyclerView, have a default LayoutManager, and have an adapter which displays all the data. I've just recently got the onClickListener() working (although I'm not sure if it should go in the onCreateViewHolder() or onBindViewHolder*(- not sure when onBindViewHolder() is called).

My SingelRow XML

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="80dp"

>


<ImageView
    android:id="@+id/item_icon"
    android:layout_width="64dp"
    android:layout_height="64dp"
    android:layout_alignParentLeft="true"
    android:layout_marginLeft="8dp"
    android:layout_marginRight="8dp"
    android:layout_marginTop="1dp"
    android:layout_marginBottom="1dp"
    android:contentDescription="icon"
    android:src="@drawable/ic_launcher"
    />


<TextView
    android:id="@+id/item_title"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_toRightOf="@+id/item_icon"
    android:layout_alignBaseline="@+id/item_icon"
    android:textColor="@android:color/darker_gray"
    android:layout_marginLeft="8dp"
    android:layout_marginRight="8dp"
    android:layout_marginTop="8dp"
    android:textSize="22dp" />

<RadioButton
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/radioButton"
    android:layout_centerVertical="true"
    android:layout_alignParentRight="true"
    android:layout_alignParentEnd="true" />

My Adapter with single choice mode and ViewHolder

public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> {
private static RadioButton lastChecked = null;
private static int lastCheckedPos = 0;
Context context;
private ArrayList<ItemData> itemsDatas;


public MyAdapter(ArrayList<ItemData> itemsDatas) {
    this.itemsDatas = itemsDatas;
}


@Override
public MyAdapter.ViewHolder onCreateViewHolder(ViewGroup parent,
                                               int viewType) {

    View itemLayoutView = LayoutInflater.from(parent.getContext())
            .inflate(R.layout.item_layout, null);


    ViewHolder viewHolder = new ViewHolder(itemLayoutView);
    return viewHolder;
}


@Override
public void onBindViewHolder(ViewHolder viewHolder, final int position) {


    if (position == 0 && itemsDatas.get(0).isSelected() && viewHolder.radioButton.isChecked()) {
        viewHolder.radioButton.setActivated(true);
        viewHolder.radioButton.setSelected(true);
        lastChecked = viewHolder.radioButton;
        lastCheckedPos = 0;
    }

    viewHolder.txtViewTitle.setText(itemsDatas.get(position).getTitle1());

    viewHolder.imgViewIcon.setImageResource(itemsDatas.get(position).getImageUrl());

    viewHolder.radioButton.setTag(this);
    viewHolder.radioButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            RadioButton cb = (RadioButton) v;


            if (cb.isChecked()) {
                if (lastChecked != null) {
                    lastChecked.setChecked(false);
                    itemsDatas.get(lastCheckedPos).setIsSelected(false);
                }

                lastChecked = cb;
                lastCheckedPos = position;
            } else
                lastChecked = null;

            itemsDatas.get(position).setIsSelected(cb.isChecked());
        }
    });


}


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

public static class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener, View.OnLongClickListener {

    public TextView txtViewTitle;
    public ImageView imgViewIcon;
    public RadioButton radioButton;


    public ViewHolder(View itemLayoutView) {
        super(itemLayoutView);
        itemLayoutView.setOnClickListener(this);
        itemLayoutView.setOnLongClickListener(this);
        txtViewTitle = (TextView) itemLayoutView.findViewById(R.id.item_title);
        imgViewIcon = (ImageView) itemLayoutView.findViewById(R.id.item_icon);
        radioButton = (RadioButton) itemLayoutView.findViewById(R.id.radioButton);
    }

    @Override
    public void onClick(View v) {
        Log.d("TAG", "onClick " + getPosition() + " " + txtViewTitle.getText().toString());
    }

    @Override
    public boolean onLongClick(View v) {
        Log.d("TAG", "onLongClick " + getPosition() + " " + txtViewTitle.getText().toString());
        return true;
    }
}}

I don't see where you set the long click listener for the radio button — OneCricketeer, Apr 02 '16 at 14:54

@cricket_007 you can see it in public static class ViewHolder — MAJHOOOOOL, Apr 02 '16 at 15:41
The long click that you have doesn't appear to do anything for the radio button, was what I meant to say — OneCricketeer, Apr 02 '16 at 15:44

If I mistake not you're asking to where you should set a onLongClickListener,In this case modify onCreateViewHolder method like this:

@Override
public MyAdapter.ViewHolder onCreateViewHolder(ViewGroup parent,
                                               int viewType) {

    View itemLayoutView = LayoutInflater.from(parent.getContext())
            .inflate(R.layout.item_layout, null);

   itemLayoutView.setOnLongClickListener(new View.OnLongClickListener() {
        @Override
        public boolean onLongClick(View v) {
            //do something
            return true;
        }
    });
    ViewHolder viewHolder = new ViewHolder(itemLayoutView);
    return viewHolder;
}

this is a revised version of your ViewHolder

 class ViewHolder extends RecyclerView.ViewHolder {

public TextView txtViewTitle;
public ImageView imgViewIcon;
public RadioButton radioButton;


public ViewHolder(View itemLayoutView) {
    super(itemLayoutView);

    .
    txtViewTitle = (TextView) itemLayoutView.findViewById(R.id.item_title);
    imgViewIcon = (ImageView) itemLayoutView.findViewById(R.id.item_icon);
    radioButton = (RadioButton) itemLayoutView.findViewById(R.id.radioButton);
    itemLayoutView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
        //what ever you want
        }
    });
    itemLayoutView.setOnLongClickListener(new View.OnLongClickListener() {
        @Override
        public boolean onLongClick(View v) {
            if(!radioButton.isSelected()){
                radioButton.setSelected(true);
            }else{
                radioButton.setSelected(false);
            }
            return false;
        }
    });
}
