After understanding the history and classification of design patterns, how should we learn design patterns? Before learning the design pattern, readers must establish a kind of consciousness, that is, the design pattern is not only a method and technology, but also an idea and a methodology. It has nothing to do with the specific language. The main purpose of learning design patterns is to establish object-oriented ideas, program to the interface as much as possible, with low coupling and high cohesion, so that the programs you design can be reused as much as possible. "Specious. Learning design patterns can better understand object-oriented ideas. Design patterns are some design skills and tricks. Don't rise to ideas and methodologies, okay?"

The system configuration change here refers to the change of activity life cycle caused by the switching of horizontal and vertical screens, thus causing the change of resources. In Android, system configuration changes will cause activity destruction and reconstruction, such as horizontal and vertical screen switching, but the switching time difference is too small for the user's eyes to detect. When the activity is rebuilt, just before the previous activity is destroyed, the system will call onSaveInstanceState (Bundle outState) to store various states at that time. In the new activity, Android will read the data through onRestoreInstanceState (Bundle savedInstanceState) and automatically restore to the View of the previous activity. Of course, in the activity, the developer's own code logic needs to be processed by himself.
