使用Realm编辑项目不存储在recyclerview中的正确位置Android

分类: 技术问答 • 2022-07-21 17:26:38
问题描述：

我正在尝试创建一个任务应用程序，我将Realm用作本地数据库。我在回收站查看这个任务。在这一刻，我可以添加一个标题，日期和时间的新任务。但是，当我尝试编辑项目时，recyclerview未更新。同样在删除一个项目后，该列表显示错误。例如，如果我单击任务1，它将显示其中的任务2，以及何时单击任务2它会在其中显示任务1。我的AddTaskActivity类是，使用Realm编辑项目不存储在recyclerview中的正确位置Android
