Question

我是Android新手，在列表视图中使用基于自定义的采用器，我的所有数据都来自数据库SQLite，数据库中的表不同。我的问题是我想从溢出菜单中的溢出菜单更改列表视图数据，但我有不同单选按钮，如果有任何用户选择了某个特定的单选按钮（如果它检查了数据列表视图），则必须更改，但是没有刷新的问题是我的代码和图片，我实际上想说什么？

如果有任何用户点击在Kings James版本上，我的数据库表名称更改为t_kjv，这存在于我的数据库用户中，单击美国标准表名称更改为t_asv 但是问题是数据库列表视图没有刷新，并且对我的列表视图没有任何作用

这是我的鳕鱼，我的默认设置是我的表名是t_kjv；活动是负载时

这是我的代码

Answer 2

这是因为您仅在onCreate处查询Cursor。

您需要从setData致电onOptionsItemSelected。另外，在适配器中交换项目之后，您可能需要调用baseAdapter.notifyDatasetChanged()。
