is a structural pattern, and its main function is to convert the interface of one class into another interface that the customer wants. The adapter mode makes it possible for those classes that would otherwise not work together because of incompatible interfaces to work together.For example, your phone only 2.5mm interface (seemingly on the Nokia dry out), but you can only buy 3.5mm, then you need to buy an adapte

WiFi technology has changed the use of many computer users, but over the years, in addition to the speed of the increase in coverage and increase the security, wireless technology has not been much development. Since 2002, however, Microsoft Research has been working on a virtualized WiFi adapter that receives almost all wireless signals through a single hardware. Now, this virtual WiFi technology has been

An intention
Transforms the interface of one class into another interface that the customer wants.
The adapter mode makes it possible for those classes that would otherwise be incompatible with the interface to work together.

The adapter mode can be either a class-structured pattern or an object
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.

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,
