Android 获取本地重复日程

您好！针对您的问题，我提供以下解答：

要获取本地重复日程，您可以使用 Android 自带的日历 API。具体步骤如下：

1. 获取日历实例

Calendar calendar = Calendar.getInstance();

2. 获取日历事件实例

ContentResolver contentResolver = context.getContentResolver();
Uri uri = CalendarContract.Events.CONTENT_URI;

// 查询条件
String selection = CalendarContract.Events.DTSTART + " >= ? AND " + CalendarContract.Events.DTEND + " <= ? AND " + CalendarContract.Events.RRULE + " IS NOT NULL";
String[] selectionArgs = new String[] { String.valueOf(calendar.getTimeInMillis()), String.valueOf(calendar.getTimeInMillis()) };

// 查询日历事件
Cursor cursor = contentResolver.query(uri, null, selection, selectionArgs, null);

3. 遍历查询结果，判断是否存在重复事件

if (cursor != null && cursor.getCount() > 0) {
    while (cursor.moveToNext()) {
        // 获取事件信息
        String title = cursor.getString(cursor.getColumnIndex(CalendarContract.Events.TITLE));
        String location = cursor.getString(cursor.getColumnIndex(CalendarContract.Events.EVENT_LOCATION));
        String description = cursor.getString(cursor.getColumnIndex(CalendarContract.Events.DESCRIPTION));
        long start = cursor.getLong(cursor.getColumnIndex(CalendarContract.Events.DTSTART));
        long end = cursor.getLong(cursor.getColumnIndex(CalendarContract.Events.DTEND));
        String rrule = cursor.getString(cursor.getColumnIndex(CalendarContract.Events.RRULE));

        // 判断是否存在重复事件
        if (!TextUtils.isEmpty(rrule)) {
            // 存在重复事件
            Log.d("Calendar", "Title: " + title + ", Location: " + location + ", Description: " + description + ", Start: " + start + ", End: " + end + ", RRule: " + rrule);
        }
    }
}

// 关闭游标
if (cursor != null) {
    cursor.close();
}

注意：在使用日历 API 时，需要添加相应的权限。可以在 AndroidManifest.xml 文件中添加以下权限：

<uses-permission android:name="android.permission.READ_CALENDAR" />
