In computer programming, adapter patterns (sometimes referred to as wrapper styles or wrappers) fit the interface of a class to what the user expects. A fitting allows a class that is usually not working together because the interface is incompatible, by wrapping its own interface in an existing class.
Basic Information
There are two types of adapter modes: Class

The adapter pattern is extremely high in our development and can be judged from the adapter that are ubiquitous in the code, from the earliest ListView, the GridView, to the current Recyclerview all need to use adapter, and the optimization problems we encounter in devel
Generally, the client class accesses the services it provides through the class interface. Sometimes, an existing class (existing class) can provide the functional requirements of the customer class, but its interfaces are not necessarily expected by the customer class. This is because the existing interface is too detailed or lacks details or the interface name is different from the one found by the customer class.
In this case, the existing interface needs to be converted to the desired interf

Introduction
In project development, there are times when you need to use "some existing objects" that were previously developed, but the interfaces required in the new environment are not satisfied by these existing objects. How do you respond to the need for such migrations? This makes it possible to reuse these objects to meet the new application environment, which is the problem that the adapter (Adapter

Speaking of adapter, it is very common in our life. For example, if you are on a business trip to Japan, you will find that the pressure of the outlets in Japan is v, our cell phone charger and laptop charger are both 220 V, so you won't be able to charge when you arrive in Japan. What should we do at this time, of course, a boost transformer is used to
Body
We know that the most important and difficult UI control in Android is the ListView list control, and you have to use the adapter adapter to use it flexibly, so I think it's necessary to learn about the adapter pattern in Java (no matter if you can use it later), After all, the Java language is a very important foundation for Android development.

As mentioned above, a user has taken the industry standard switch (a standard standardswitcher, which relies on the istandardswitchable interface to work, but currently our lamp does not support this interface) and appears in front of me, he shouted that his "Standard switch" should be able to turn on our lights. Well, this requirement is reasonable and should be supported. But the damn thing is, why didn't we know the standard as ea
