在视图滚动条上限制OnBindViewHolder

Question

I have created a recycler view leaderboard adapter to display people names with their ranks. When I scroll down and up the serial no changes and it gets messed up. It's because the onBindViewHolder is being called again for the integer which sets the serial number.

How do I stop the method while scrolling? Is there any way?

Answer 1

Your thinking is wrong here. onBindViewHolder is expected to be called when you scroll and you shouldn't try to stop it from being called.

The problem here is that you do the counting in onBindViewHolder . This is wrong. You are only supposed to bind the data to your views here, just as the method name implies. Don't change your data in onBindViewHolder and the problem will go away. Instead, prepare the data before sending it to the adapter.
