how to get ID of the items in recyclerview

Question

i\'m using slide to delete from recyclerview but the problem comes when getAdapterPosition() doesn\'t match with the row_id of sql table. how can i get id from the adapter a

Answer 1

Create this method in your adapter to the get id of that specific object and pass the id to the delete the fuction of DbHelper class.

int getId(int position){
    return data.get(position).ID;
}

And avoid accessing the members of a class directly. Instead of that you can use getter and setter methods.

And for updating the recyclerview after adding new data you can call notifyDataSetChanged() in the respective insert method in your adapter.

EDIT:

To add a new element into your recycler view add this method in your adapter

void addItem(Informationn infoObj){
     data.add(infoObj);
     notifyDataSetChanged();
}

Call this method using your adapter object and pass the new item as parameter and your recyclerview will be updated with the new items

Answer 2

Use the getItemId method if you have overridden it in yr adapter like so

@Override
     public long getItemId(int position) {
         return yrModel.getId();
       }

    yrViewHolder.idTv.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Long id = yrList.get(position).getId();

            Log.e(TAG, "List item ID: " + id);
        }
    });

That way u get the item position and the ID using the getItemId method
