scrollingCache?

Question

Can anybody explain the meaning of scrolling cache in Android. I stumbled upon this word, but was unable to find the explanation, either on android official web

Answer 1

I think you are talking about the following:

Imagine a list of 50 items where only 10 items are visible. Android will cache the next and previous (estimate) 5 items in a list item.

When you start scrolling through the list it will reuse the invisible item views, using the ArrayAdapter's function getView() For example if you are scrolling to the top it will take a view on the bottom and place it on top with new data.

So scrolling cache are the next and previous items above/under the visible items.
