whats adapter

What is the adapter mode? In computer programming, the adapter mode (sometimes called packaging style or packaging) adapts a class interface to what the user expects. The adapter can work together classes that cannot work together because of the incompatibility of interfaces, by encapsulating their own interfaces in an existing class. How does one implement the

Android note 11. ListView + AdapterUnderstanding Adapter 1. ListViewListView is a common component in Android development. It displays data in the form of a list. Generally, a ListView consists of the following three elements:1. View: Displays the list view, which is usually specified by an xml file. As we all know, the Android interface is basically completed by the xml file, so the ListView interface should also use the xml definition. For example,

Adapter data changes the implementation principle and case of the existing View, adapterview First, let's talk about the inheritance relationship of the specific class of the Adapter, as shown in Adapte serves as a bridge between AdapterView and View. The Adapter loads View (such as the data to be displayed in ListView and girdView ). The data to be displayed i

However, the client does not want to call this class, but instead wants to invoke a specific interface such as the target interface.So if you want to call the Adaptee.methoda

Analysis from the Bluetooth Technology: 1. Distance: many sellers on the market announced support for 20 m, 30 m, 50 m, etc. In fact, this is the distance from Bluetooth support for sellers.Is there two standard classes? 1 and class? 2, class? 1 supports a standard distance of 100 m and class2 supports a distance of 10 m. In fact, the distance is notIn the case of obstacles, class? 2 can support up to 10-20 meters, class? 1 can support 80-90 meters, while some sellers advertise 30 m, 50 m, and o

2006.1.5 Li Jianzhong The concept of adaptation (conversion) is everywhere. Adaptation, that is, the original incompatible interfaces are converted into compatible interfaces without changing the original implementation. Motivation) In software systems, due to changes in the application environment, we often need to put "some existing objects" in the new environment for application, however, the interfaces required by the new environment are not met by these existing objects. How can we cope

Adapter Pattern)Before the formal start, let's first think about a few questions: if the existing new project can use a lot of legacy code in the old project, are you planning to finish the new project from the beginning or understand the module functions and interfaces of the old project? If you have learned about the legacy code and find that several important functional module interfaces are different (because they may come from multiple old projec

You want to use a class that already exists, and its interface doesn't fit your needs.Creating a class requires working with other classes to accomplish the task, requiring an adapter to transfer methods from other classes to the adapterWhat is adapter mode: There is a target client class that wants to apply an interface to an already existing class, but the interface of the existing class does not conform
