Answer 1

如果用户将自己标记为不缺席并且他甚至不在学校怎么办？

你可以查看 Firebase Notifications

Firebase is a mobile and web application platform with tools and infrastructure designed to help developers build high-quality apps. Firebase is made up of complementary features that developers can mix-and-match to fit their needs.

编辑

With Firebase Notifications, you can target notifications to a single, specific device. You'll need access to the registration token for the app instance on that device, in order to provide the token when composing and sending the notification in the Notifications console.

请检查this，你会得到它！

Answer 2

使用SharedPreferences

当您登录商店时，是否是经理登录：

private final String KEY_PREF_NAME = "UserInfoSettings", 
KEY_IS_MANAGER = "KEY_IS_MANAGER";

private SharedPreferences mPref = getSharedPreferences(KEY_PREF_NAME, Context.MODE_PRIVATE);
mPref.edit()
                .putBoolean(KEY_IS_MANAGER, value)
                .commit();

值=真或假

当您收到通知时，检查登录的人是否是经理：

if(mPref.getBoolean(KEY_IS_MANAGER, false)){
//TODO show notification
}

注销时清除首选项：

mPref.edit().clear().commit();
