recyclerview中的数据绑定通用列表

Question

I would like to reuse the same fragment (that contains a RecyclerView) to show different lists:

List<Pizze>, List<Pasta>, List<Wine>.

Let's consider that i have this 3 objects (Pizze,Pasta,Wine)and all those objects have the same fields: name and price. This RecyclerView in the fragment should show only those two fields: name and price for every list. In the layout i have to express the variable type:

variable name="items" type="List<Pizza>

How can i pass a generic list here?

Answer 1

一个对象数组怎么样，第一个是名称，第二个是价格。

Answer 2

Just use generics.

private List<T> mItems;

public void setItems(List<T> items) {
        mItems = items;
        notifyDataSetChanged();
}
