這是我的RecyclerFrame代碼，在這裏你可以看到cPoints.add(jsonObject.getInt("charging_capacity"));我想在裏面RecyclerViewer顯示此，我現在只能顯示的名稱數組。Recyclerview不工作，應用程序崩潰
這是我的RecyclerAdapter代碼：

public RecycleAdapter(ArrayList<String> names, ArrayList<Integer> cPoints){
ArrayDataset = names;
ArrayDataset2= cPoints;
}
@Override
public RecycleAdapter.MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType){
View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.fragment_card_view, parent, false);
MyViewHolder vh = new MyViewHolder(v);
return vh;
}
@Override
public void onBindViewHolder(MyViewHolder holder, int position){
holder.mTextView.setText(ArrayDataset.get(position));
holder.mTextView2.setText(ArrayDataset2.get(position));
holder.mImageView.setImageResource(R.drawable.ic_local_parking_black_24dp);
}
@Override
public int getItemCount() { return ArrayDataset.size(); }
}
這是我做SOFAR，但是當我在我的應用程序打開的應用程序崩潰任何人都可以幫我更新後解決這個
logcat的代碼代碼
