Air mobile andriod ios paging Control

Air mobile andriod ios paging Control

Recently, I have studied how to use flex to write android and ios apps. I encountered a paging loading problem. We used flex sdk 12 and air 15 didn't find a paging component similar to android ListView, so I wrote it with my colleagues, and the effect is still acceptable. Drag and refresh up, drag and load down. If you are interested, you can take it away. If you have better notifications, post the Code directly.
