必需的：
1.我想在Android中制作一个分段的标题列表视图。
2.这应该是滑动删除一个项目，像Gmail App.but Gmail App不包含Section Header的Undo选项。
3.我的应用程序应该有部分标题。
我尝试了下面提到的链接，让滑动与撤消按钮一起删除。它工作得很好。
问题：
编辑：1（列表视图）
1.我在 Listview Link-Swipe 中找到了Swipe to Delete a item with Undo 以删除 listview 项目和Section Header Using Listview link-Section header in listview 的代码。
2.两者都有两个不同的基本适配器我遇到了一些错误，请帮助我合并该适配器或建议我任何新的方法来在滑动中添加部分标题以删除列表视图项目。
