Android Question

Application is crashing when I start activity from setOnClickListener of RecyclerView's adapter

I've got a RecyclerView which is loading the content of my String Arrays which works fine, however I want to open a new Activity depending on which view they have pressed.

What I have done:

public class WinnersListAdapter extends RecyclerView.Adapter<WinnersListAdapter.WinnersCardViewHolder>
{
Context context;
LayoutInflater inflater;
List<ListLottery> lotteryList;

public WinnersListAdapter(List<ListLottery> loteries,Context context){
this.context = context;
this.lotteryList = loteries;
inflater = LayoutInflater.from(context);
}

@Override
public WinnersListAdapter.WinnersCardViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View v = inflater.inflate(R.layout.prevlotterycards_layout,parent,false);

// Toast.makeText(context,"Hi",Toast.LENGTH_SHORT).show();
WinnersListAdapter.WinnersCardViewHolder viewHolder = new WinnersListAdapter.WinnersCardViewHolder(v);
return viewHolder;
}

@Override
public void onBindViewHolder(WinnersListAdapter.WinnersCardViewHolder holder, int position) {
final ListLottery lottery = lotteryList.get(position);
holder.lottery_date.setText(lottery.getLotteryDate());
holder.lottery_date.setTag(holder);
holder.itemView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(context,"clicked--"+lottery.getLotteryId(),Toast.LENGTH_SHORT).show();
Intent intent = new Intent(context,WinnerActivity.class);
intent.putExtra("lotteryId",lottery.getLotteryId());
context.startActivity(intent);
}
});
}

@Override
public int getItemCount() {
return lotteryList.size();
}

class WinnersCardViewHolder extends RecyclerView.ViewHolder {
TextView lottery_date;
CardView card_lotteryList;

public WinnersCardViewHolder(View itemView) {
super(itemView);
lottery_date = (TextView) itemView.findViewById(R.id.l_lottery_date);
card_lotteryList = (CardView) itemView.findViewById(R.id.card_lotteryList);
}
}
}


I have read many articles to resolve it and did stuff according that but could not find any solution.

Answer

Actually, I can not answer your question because you didn't post your logcat but there are few things you can to check :

1 - Check that your activity already declared in AndroidManifest.xml

2 - Check you context is the context of Activity or applicationContext ? If is't not the context of Activity so you need to add flag

Intent i = new Intent(this, WinnerActivity.class);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
