[ListView] How to implement endless scroll from bottom & top?

[ranyefet]

Hello all,

I'm trying to implement something similar to Sunrise

Basically I have a list which I want to:

1. Load new items when scroll reach to end and add them to the end of the list onEndReached
2. Load old items when scroll reach to top and add them to the beginning of the list
3. I need to show section headers renderSectionHeader and I need to know when the current section was changed.
4. I want to jump into specific section in the list

Is it possible to implement it with ListView? If so, do you have any tips on how to do that?

Your help is appriciated,
Ran.

We just implement a waterfall listview.
checking whether the scrollview reached the bottom by RCTViewManager.measureLayout.
then fetch data for next section list and try to merge data to the dataSource of ScrollView.
As the dataSource changed by setState , the scrollView will be rerendered.

But in this case, the scrollview will be complete rerendered everytime when you merge data to dataSource.

I have no better idea to implement this
