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.

我建议您创建一个单一的Activity，并从您的适配器中传递唯一的id或数据，根据这些数据设置或获取数据，因为如果RecyclerView中的数据量很大，比如50或100条，那么为每一条数据创建一个新的Activity就会很困难。像这样传递：
Intent intent = new Intent(context, your_activity);
intent.putExtra("your_key", "" + your_data);
context.startActivity(intent);
然后在您的第二个Activity中获取它：
String intentValue = getIntent().getStringExtra("your_key");
然后可以使用这个id来获取您的项目细节。

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
