Мое приложение должно анализировать данные JSON и отображать их в виде переработчика. Когда я запускаю приложение, оно вылетает со следующей ошибкой: 
Я повторно проверял свой код несколько раз, чтобы убедиться, что я вызываю правильные файлы ресурсов, но я все еще не могу найти источник проблемы. Logcat говорит мне, что проблема в методе onBindViewHolder в классе адаптера представления рециркулятора, но для меня все выглядит нормально. Может кто-то указать мне верное направление? Вот соответствующий код:
Адаптер Recycler View:
public class IndRvAdapter extends RecyclerView.Adapter<IndRvAdapter.MyViewHolder> {
private Context context;
private List<Ind> indList;
public IndRvAdapter(Context context, List<Ind> indList) {
this.context = context;
this.indList = indList;
}
@NonNull
@Override
public MyViewHolder onCreateViewHolder(@NonNull ViewGroup viewGroup, int i) {
View view;
LayoutInflater inflater = LayoutInflater.from(context);
view = inflater.inflate(R.layout.ind_card, viewGroup, false);
final MyViewHolder viewHolder = new MyViewHolder(view);
viewHolder.indView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Intent i = new Intent(context, SingleInd.class);
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
i.putExtra("pacshort", indList.get(viewHolder.getAdapterPosition()).getPacshort());
i.putExtra("supopp", indList.get(viewHolder.getAdapterPosition()).getSuppopp());
i.putExtra("candname", indList.get(viewHolder.getAdapterPosition()).getCandname());
i.putExtra("district", indList.get(viewHolder.getAdapterPosition()).getDistrict());
i.putExtra("amount", indList.get(viewHolder.getAdapterPosition()).getAmount());
i.putExtra("party", indList.get(viewHolder.getAdapterPosition()).getExpParty());
i.putExtra("payee", indList.get(viewHolder.getAdapterPosition()).getPayee());
i.putExtra("date", indList.get(viewHolder.getAdapterPosition()).getDate());
i.putExtra("origin", indList.get(viewHolder.getAdapterPosition()).getOrigin());
i.putExtra("source", indList.get(viewHolder.getAdapterPosition()).getSource());
context.startActivity(i);
}
});
return viewHolder;
}
@Override
public void onBindViewHolder(@NonNull MyViewHolder myViewHolder, int i) {
myViewHolder.pacshorts.setText(indList.get(i).getPacshort());
myViewHolder.supOpp.setText(indList.get(i).getSuppopp());
myViewHolder.candName.setText(indList.get(i).getCandname());
myViewHolder.district.setText(indList.get(i).getDistrict());
}
@Override
public int getItemCount() {
return indList.size();
}
public class MyViewHolder extends RecyclerView.ViewHolder{
TextView pacshorts, supOpp, candName, district;
LinearLayout indView;
public MyViewHolder(@NonNull View itemView) {
super(itemView);
pacshorts = itemView.findViewById(R.id.tv_pacshort);
supOpp = itemView.findViewById(R.id.tv_suppopp);
candName = itemView.findViewById(R.id.tv_candname);
district = itemView.findViewById(R.id.tv_district);
indView = itemView.findViewById(R.id.ind_view);
}
}
}
