 itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent=new Intent(itemView.getContext(),detail_activity.class);
                itemView.getContext().startActivity(intent);

            }
        });

Answer 1

OnClickItem

Intent intent=new Intent(itemView.getContext(),detail_activity.class);
intent.putExtra("id","ITEM_ID");
itemView.getContext().startActivity(intent);

In Activity class

String intentValue = getIntent().getStringExtra("id");

Do whatever you want by id.

Answer 2

As i recommend you to create a single Activity and pass the unique id or data from your adapter and set or get data according to this data because if recyclerView data come in large amount like 50 or 100 so its hard to create a new activity for each and every one. like pass the

Intent intent=new Intent(context,your_activity);
intent.putExtras("your_key",""+you_data);
context.startActivity(intent)

and get it into your second activity

String intentValue = getIntent().getStringExtra("id");

and after this use this id to get the your items details
