how to update view in a single item of recycler view

Question

if each item of recycler view has multiple items (Button and textview)

I have interface to handle Recycler's item click , I want upon clicking Recycler view item , be able to update text view and button but from outside of the adapter class ,

how could I achieve this ? thanks

Answer 1

call adapter.notifyItemChanged(position) on the adapter to change only a single object

EDIT: Based on your comment:

you don't need reference of textview. Just update the state of the item in the list at that position. For exmaple, take a boolean, isclicked and mark it as true for position = x

Hadle the text and UI inside the onbindviewholder only based on the isClicked = true or false.

Answer 2

您可以使用AdapterObject.NotifyDataSetChanged而不是在更新列表中的数据之后再次设置适配器。
