定制适配器类中的调用活动方法

Question

So I am currently trying to refresh a recyclerview in another activity but the problem is it doesn't like the casting or the way I am calling it.

Any ideas?

Answer 1

From the crashlog, it would appear you are passing an ApplicationContext to your recyclerview. Instead, you need to pass your activity as Context, and ensure your Activity implements the UserRView interface.

A cleaner way would be to pass a context and also pass a UserRView to your adapter, so you do not have to cast the context to UserRView, and you can continue to pass an application context if you prefer.

Edit: replace this code

adapter = new CustomRAdapter(list, getBaseContext());

with

adapter = new CustomRAdapter(list, this);
