Java Design Pattern modeling and implementation of cainiao series (9) Appearance Pattern
Facade: Solves the dependency between classes. Like spring, you can configure the relationship between classes to the configuration file, the appearance mode is
The relationship is placed in a Facade class, which reduces the coupling between the class and the class. This mode does not involve interfaces.I. uml modeling
dependency is that a method in a class can manipulate an instance of another class. In practical programming, it is recommended to minimize the number of interdependent classes. As shown in the following:Aggregation (HAS-A)Because the order needs to indicate what book to order, this involves the book class, that is, contains the book class. The difference between aggregation and dependency is that the order class can not have all the account class objects, but must have all the book class objec

Within notification, an action is defined in a PendingIntent, which contains an intent used to start the activity in your app. To associate PendingIntent with a gesture, you need to call the appropriate icationicationcompat. Builder method.
For example, if you want to start the activity when you click the notification text, you need to call setContentIntent () of icationicationcompat. Builder to add PendingIntent. Starting an activity
