how to pass the value from one activity to another by using Context and output is to be seen in another actitvity?

Question

when i click on the text the app crashes and error appears in the line below mentioned.

public class DataHolder extends RecyclerView.ViewHolder {

    public TextView table;
    int tableData;

    public DataHolder(final View itemView) {
        super(itemView);

        table = (TextView) itemView.findViewById(R.id.table_list);

        table.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Log.d("ashu", "onClick: is called");
                tableData = Integer.parseInt(table.getText().toString());

                Context context = view.getContext();
                Intent intent = new Intent(context, RecyclerAdapterNew.class);

                intent.putExtra("transfer", tableData);
                Log.d("ashu", "last lone is to be executed");

                context.startActivity(intent);//error in this line
            }
        });



    }


}

my second class is this in which i have to pass the value through the putExtra but the app crashes in the previous Activity when i click my text

public class RecyclerAdapterNew extends RecyclerView.Adapter<DataHolderNew> {

    int tableData;


    @Override
    public DataHolderNew onCreateViewHolder(ViewGroup parent, int viewType) {

        Context context = parent.getContext();
        LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View view = inflater.inflate(R.layout.table_values, parent, false);

        Intent intent = ((Activity) context).getIntent();
        tableData = intent.getIntExtra("transfer", tableData);

        return new DataHolderNew(view);
    }


    @Override
    public void onBindViewHolder(DataHolderNew holder, int position) {

        holder.table_value.setText((position + 1) * tableData);

    }


    @Override
    public int getItemCount() {
        return 10;
    }

}

make publc Context con; and pass Context from your hosting activity to recyclerview adapter. and then use it — Divyesh Patel, Feb 09 '17 at 06:38
Pass superclass context to adapter through constructor and use that context in the adapter and viewholder. — Mayur Gangurde, Feb 09 '17 at 06:45
You have to use Activity context for first parameter of startActivity() method. You can do this in 2 ways. 1- using interface(recommend): when an item in RecyclerView clicks send data of current item to host activity by interface 2- Add an context parameter for constructor of your adapter and send host activity to this parameter then save it in a field. — hosseinAmini, Feb 09 '17 at 06:45
