Android 获取日历本地账号的demo

以下是获取 Android 日历本地账号的示例代码：

// 获取日历账户
private String getCalendarAccount() {
    String account = "";
    Cursor cursor = null;
    try {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            cursor = getContentResolver().query(CalendarContract.Calendars.CONTENT_URI,
                    new String[]{CalendarContract.Calendars._ID, CalendarContract.Calendars.ACCOUNT_NAME},
                    CalendarContract.Calendars.ACCOUNT_TYPE + " = ? AND " + CalendarContract.Calendars.OWNER_ACCOUNT + " = ?",
                    new String[]{"com.android.exchange", "your.email@example.com"}, null);
        } else {
            cursor = getContentResolver().query(CalendarContract.Calendars.CONTENT_URI,
                    new String[]{CalendarContract.Calendars._ID, CalendarContract.Calendars.ACCOUNT_NAME},
                    CalendarContract.Calendars.ACCOUNT_TYPE + " = ?",
                    new String[]{"com.android.exchange"}, null);
        }
        if (cursor != null && cursor.moveToFirst()) {
            int accountIndex = cursor.getColumnIndex(CalendarContract.Calendars.ACCOUNT_NAME);
            account = cursor.getString(accountIndex);
        }
    } catch (Exception e) {
        e.printStackTrace();
    } finally {
        if (cursor != null) {
            cursor.close();
        }
    }
    return account;
}

其中，`CalendarContract.Calendars.CONTENT_URI` 是日历的内容 URI，`CalendarContract.Calendars._ID` 是日历 ID，`CalendarContract.Calendars.ACCOUNT_NAME` 是日历账户名称，`CalendarContract.Calendars.ACCOUNT_TYPE` 是日历账户类型，`CalendarContract.Calendars.OWNER_ACCOUNT` 是日历所有者账户。根据实际情况修改参数即可。
