Is it possible to make CursorAdapter be set in recycleview, just like ListView?

Question

I didn't google out a solution till now to replace listview in my project, because I need to use the cursor linked with the sqlite.

Old way as followed: listview.setAdapter(cursorAdapter) in this way, I can get the cursor to deal with data in database

but now, recycleview.setAdapter(recycleview.adapter) it doesn't recognize the adapter extending BaseAdapter

so anyone can give me a hand?

Implementing it yourself is actually quite simple:

public class CursorAdapter extends RecyclerView.Adapter<ViewHolder>{

    Cursor dataCursor;

    @Override
    public int getItemCount() {
        return (dataCursor == null) ? 0 : dataCursor.getCount();
    }


    public void changeCursor(Cursor cursor) {
        Cursor old = swapCursor(cursor);
        if (old != null) {
          old.close();
        }
      }

     public Cursor swapCursor(Cursor cursor) {
        if (dataCursor == cursor) {
          return null;
        }
        Cursor oldCursor = dataCursor;
        this.dataCursor = cursor;
        if (cursor != null) {
          this.notifyDataSetChanged();
        }
        return oldCursor;
      }

    private Object getItem(int position) {
        dataCursor.moveToPosition(position);
        // Load data from dataCursor and return it...
      }

}
