Good day. I have a RecyclerView that lists the CardView. Each CardView consists of TextView and CheckBox. Mark CheckBox by clicking on CheckBox itself is not very convenient (because the checkbox area is small for a finger). I would like to checkmark by clicking around the whole CardView. Put RecyclerView on ClickListner:

rv.addOnItemTouchListener(new RecyclerItemClickListener(getActivity(), rv, new RecyclerItemClickListener.OnItemClickListener() { @Override public void onItemClick(View view, int position) { Toast.makeText(getActivity(), "Click" + AddFilterAdapter.getBox(), Toast.LENGTH_SHORT).show(); } }));

Further, as it seems to me, you need to determine the CardView position in the adapter and check the required CheckBox by position. But how to implement it? Tell me an example.

    You can add checkbox logic directly to the view holder, for example

     public class ViewHolder extends RecyclerView.ViewHolder{ private View itemView ; private CheckBox checkbox; public ViewHolder(View itemView){ super(itemView) this.itemView=itemView; this.checkbox =(CheckBox) itemView.findViewById(R.id.checkbox) } void bindItem(RecyclerView item, On click listener onClick) { CheckBox.isChecked(item.isChecked): itemView.setOnClickListener(onClick) ; } } public class RecyleclerItem { private <YOUR ITEM TYPE> object ; private boolean isChecked ; } onBindViewHolder(holder, position) { RecyclerView item = itemList.get(position); holder.bindItem(item, v-> { item.isChecked =! item.ischecked; notifyItemChenged(position); } }
