android 修改本地日程后 修改后的数据查看 demo

您可以使用以下代码来获取修改后的日程数据：

// 获取 ContentResolver
ContentResolver cr = getContentResolver();

// 定义查询条件
Uri uri = CalendarContract.Events.CONTENT_URI;
String[] projection = new String[]{
        CalendarContract.Events._ID,
        CalendarContract.Events.TITLE,
        CalendarContract.Events.DESCRIPTION,
        CalendarContract.Events.DTSTART,
        CalendarContract.Events.DTEND
};
String selection = CalendarContract.Events.TITLE + " = ?";
String[] selectionArgs = new String[]{"My Event"};

// 查询数据
Cursor cursor = cr.query(uri, projection, selection, selectionArgs, null);

// 遍历结果集合
while (cursor.moveToNext()) {
    String eventId = cursor.getString(cursor.getColumnIndex(CalendarContract.Events._ID));
    String title = cursor.getString(cursor.getColumnIndex(CalendarContract.Events.TITLE));
    String description = cursor.getString(cursor.getColumnIndex(CalendarContract.Events.DESCRIPTION));
    long startTime = cursor.getLong(cursor.getColumnIndex(CalendarContract.Events.DTSTART));
    long endTime = cursor.getLong(cursor.getColumnIndex(CalendarContract.Events.DTEND));

    Log.d("TAG", "Event Id: " + eventId);
    Log.d("TAG", "Title: " + title);
    Log.d("TAG", "Description: " + description);
    Log.d("TAG", "Start Time: " + new Date(startTime));
    Log.d("TAG", "End Time: " + new Date(endTime));
}

// 关闭游标
cursor.close();

其中，`CalendarContract.Events.TITLE` 表示查询条件，你可以根据自己的情况修改它。注意，查询数据需要获取相应的权限。
