How To Get Hashmap Data In Recycle View

Post a Comment
I had seen many examples regarding Hashmap Data but I am not getting the data as required. Here is my code: public class QuickGraphAdapter extends RecyclerView.Adapter

Solution 1:

change your onBindViewHolder(); 

@Override
        public void onBindViewHolder(QuickGraphAdapter.GraphHolder holder, int position) {
            for (Map.Entry<String, ArrayList<CoinPriceGraph>> graph : GraphValue.entrySet()) {
               ArrayList<CoinPriceGraph> graphs = graph.getValue();
              Log.e(TAG, "Key Name: " + graph.getKey());
            holder.tvGraphName.setText(graph.getKey());
            }


        }
