Required:
1.I want to Make a Sectioned Header Listview in Android.
2.That should be Swipe to delete a item, with Undo option like Gmail App.but Gmail App not contains Section Header.
3.My Application should be have Section Header.
i tried below mentioned link for Swipe to delete along with Undo button. its worked perfectly.
Problem:
EDIT :1(ListView)
1.i found the code for Swipe to Delete a item with Undo in Listview Link-Swipe to delete a listview item and Section Header Using Listview link-Section header in listview.
2.both are having two different Base Adapters Iam getting some Error,Please help me to merge that adapters or suggest me any new way to add section Header in Swipe to Delete a Listview items.
