|
|
|

- import android.net.Uri; :引入 Uri 类,它在Android开发里常用于表示统一资源标识符,例如访问内容提供者(Content Provider)时,就需要用 Uri 来指定要操作的数据资源位置
|
|
|
|
|
- 这段代码定义了多个整型常量,作为系统文件夹的标识符:
|
|
|
|
|
- ID_ROOT_FOLDER 设为 0 ,代表默认文件夹。
|
|
|
|
|
- ID_TEMPARAY_FOLDER 设为 -1 ,用于存放那些不属于任何文件夹的笔记。
|
|
|
|
|
- ID_CALL_RECORD_FOLDER 设为 -2 ,用来存储通话记录相关的文件夹。
|
|
|
|
|
- ID_TRASH_FOLER 设为 -3 ,推测是回收站文件夹。
|
|
|
|
|
- 定义了一系列静态常量字符串,这些字符串大概率是用于在 Intent 传递额外数据时的键名,不同的键对应不同类型的数据,比如提醒日期、背景颜色ID、小组件相关ID和类型、文件夹ID、通话日期等。
|
|
|
|
|
- 又定义了几个整型常量,用于区分不同类型的小组件, TYPE_WIDGET_INVALIDE 值为 -1 表示无效小组件, TYPE_WIDGET_2X 值为 0 、 TYPE_WIDGET_4X 值为 1 可能对应不同尺寸规格的小组件。
|
|
|
|
|
- 定义了两个 Uri 常量:
|
|
|
|
|
- CONTENT_NOTE_URI :通过 Uri.parse 方法,根据之前定义的 AUTHORITY 拼接出用于查询所有笔记和文件夹的 Uri 。
|
|
|
|
|
- CONTENT_DATA_URI :同样方式拼接出用于查询数据的 Uri ,这些 Uri 在与内容提供者交互、获取数据时是关键元素。
|
|
|
|
|
- 定义了一个接口 NoteColumns ,不过目前接口内部还没有具体的方法或者常量定义,通常接口用于定义一组相关方法的签名,后续大概率会在这里添加与笔记列相关的常量定义,方便数据库操作时统一列名。
