, finally is the introduction of these kinds of design patterns, after reading this article, you should be found in fact, Android design patterns are everywhere, not lack of design patterns, but the lack of a pair of discovered eyes.Of course, the design pattern of the proposed is to solve specific problems, when we encounter similar problems, can be from the perspective of design patterns to think and solve problems, this should be my biggest harvest

Singleton mode is the most common and simplest design pattern in design mode, which ensures that only one instance exists in the program and can be accessed globally. For example, in the Android real-world app development using the account information object management, database objects (Sqliteopenhelper), etc. will be used in the singleton

This example for you to share the Android adapter mode source code for your reference, the specific content as follows 1. Model Introduction Definition of the 1.1 pattern: The adapter pattern transforms the interface of a class into another interface that the client expects, so that two classes that cannot work together because of an interface mismatch can work together. 1.2 Usage Scenarios for

Template Method mode for Android source code analysis, android source codeMode definition Defines the framework of an algorithm in an operation, and delays some steps to the subclass.

In this article, we introduce the combination pattern (Composite pattern), which is also known as part of the overall pattern (part-whole pattern), one of the structural patterns. The combination mode is simple, it considers a set of similar objects as an object processing, and combines the objects according to a tree structure, and then provides a uniform way to access the corresponding object, ignoring the difference between the object and the objec

popular, it is no longer just used in the push mail, more in our app.When we develop the applications that need to interact with the server, we basically need to get the server-side data, such as "earthquake emergency traffic" need to get the latest seismic information on the server. There are generally two ways to get information about updates on the server that are not timed: the first is the way the client uses pull, which is to get information from the server at a time and see if there is a
