to store activity-related information and recover the data the next time they return to activity. Through these two functions. Developers can store interface-related information in special scenarios to enhance the user experience.Basic Use Reference: Links5. Summary 1. Advantages(1) To provide users with a mechanism to restore the state, you can make it easier for users to return to a historical state.(2) To achieve the encapsulation of information, so that users do not need to care about the s
. Summary 1. Advantages(1) An abstract coupling between the observer and the observed is a response to business change.(2) Enhance the flexibility and scalability of the system.2. DisadvantagesIn the application of the observer pattern needs to consider the development efficiency and the efficiency of the problem, the program includes an observer, a number of observers, development, debugging and other content will be more complex, and in Java, the notification of messages is generally sequentia
Analysis of Android source code design patterns and practices (23rd)Chapter 2 appearance Mode The appearance mode is one of the structural design modes. It is frequently used in development and is a common method for encapsulating APIs. Third-party sdks we often use are basically used in the appearance mode, which can shield users from many implementation detai

, start service and set up wallpaper and so on. These jobs are not ContextImpl implemented in. Instead, it is handed over to the detailed subsystem for processing. Contextthis abstract class defines a set of interfaces that are ContextImpl implemented. In this way, users often do not need to understand each subsystem. This masks detailed implementation details for the user. Reduced cost of use.6. Summary 1. Strengths(1) The client program hides the details of the subsystem, thus reducing the cus
Spring is based on Rod Johnson's "Expert One-on-one development and Design". The main goal is to reduce the complexity of enterprise applications by using basic JavaBean to accomplish things that were previously only done with EJBS. This series of source learning is based on the Spring-4.3.11 version.I. The overall architecture of spring, spring can be summed up in a few parts:(1) Core ContainerThe core con

non-terminator interpreter, and when building the abstract syntax tree. It is convenient to use the new interpreter object for a detailed explanation.2. Disadvantages1. Each grammar produces a non-terminator expression, and the grammatical rules are more complex. It is possible to generate a large number of class files, which poses a lot of trouble for maintenance.2. The interpreter mode is due to the use of a large number of loops and recursion. Efficiency is a problem, especially when it come
