The adapter mode (Adapter pattern) is a bridge between two incompatible interfaces. This type of design pattern belongs to the structural pattern, which combines the functions of two separate interfaces.Intent: 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 othe
Why use Patterns: patterns are a way of doing things, that is, the way to achieve a goal, or technology.The purpose of the adapter model is to retain the services provided by existing classes and to provide customers with interfaces to meet customer needs. Class Adapter: The client defines the interface and implements the interface, the method in its own class library has a better implementation, but the me
Android Development, we can not leave adapter, each project has a lot of places need to adapter, then how do we let ourselves write adapter code less? That is the encapsulation adapter, let our adapter become omnipotent adapter. B
Transforms the interface of one class into another interface that the customer wants. Those classes that would otherwise not work together because of incompatible interfaces can work together.
Scenario: You want to reuse some existing classes, but the interfaces are inconsistent with the reuse environment requirements.
Pattern feature: Transforms the interface of a class into another interface that the customer wants.
Classification: Class adapters (through multiple inheritance), object adapter
Https://en.wikipedia.org/wiki/Adapter_patternIt allows the interface of an existing class to be used as another interface.It is often used to make existing classes work with others without modifying their source code.Scenario: let an existing class work correctly based on other classes, and do not need to modify their source code.Example: Notebook power Adapter (Adapter), so that the notebook (client) work

Adapter design mode, adapter ModeAdapter design mode definition:
Converts an interface of a class to another interface that the customer wants. The Adapter mode allows the classes that cannot work together due to incompatibility of interfaces to work together.
It sounds amazing. In fact, the adapter is everywhere in o
We often encounter this situation in development: there are some features that cost a great deal of their own development, but the existing third-party libraries are less mature and we can use them temporarily. However, once the need to modify the dependent library, the source code also needs to be modified on a large scale, there is no way to minimize the extent of the changes? At this point we can consider using adapter mode.First, the definitionThe
Adapter mode:An interface that transforms an interface of a class into another desired class. Adapters allow the interfaces to work with incompatible classes.interfaceofclassintointerface clients expect. Adapter lets classes work together that couldn‘t otherwise because of incompatible interfaces.Simply put, the adapter mode is to add an intermediate layer, remem
I. What is an adapter and what is the adapter for?Adapters are Adapterview views such as ListView-List View control, Gallery-thumbnail browser Control, GridView-Grid control, Spinner-drop-down list control, Autocompletetextview-Auto prompt text box, Expandablelistview-a list control that supports the expand/Shrink feature, and so on) bridges the data to process the data and bind the data to the Adapterview.
?Adapter mode: the interface of a class is transformed into another interface that the customer expects, and the adapter lets the originally incompatible classes work together seamlessly.appearance mode: provides a unified interface for accessing a group of interfaces in a subsystem. The appearance defines a high-level interface that makes the subsystem easier to use.?Object adapter:Class
Why do I need adapter? Short answer: Simplifying"Event Source" can register (addxxxlistener) Listener object and Send event objectWindowListener listener = ...; Frame.addwindowlistener (listener);Specific event corresponding to a specific listener interface (Listener interface); Public Interface windowlistener{ void windowopened (windowevent e); void windowclosing (WindowEvent e);}In order to handle a particular event, the listener implements t
On the basis of custom ViewGroup (5): http://www.jb51.net/article/100639.htm, add the use of adapter to fit the data, which is more convenient, just use the adapter adapter data and cannot be updated.
Package com.example.libingyuan.horizontallistview.ScrollViewGroup;
Import Android.content.Context;
Import Android.util.AttributeSet;
Import Android.util.Displ
(New Operationadd, A, b);
Case "Minus": Return Context.getresult (New, Operationminus, A, b);
......
}
}
private static int GetResult (Operation ins, int a, int b) {return
ins.calculateresult (a,b);
}
In this way, our client code can be changed to:
public class customer{public
static void Main (Strings args[]) {The context
ins = new context ();
int result Ins.getresult ("add", 1,2);
}
Compare the client code for the previous s
1. Effect of adapter mode assume that a developed class and its specific method exist, but there is an inconsistency between the existing interface and the reuse method, at this time, we must use a mechanism to convert existing methods into other acceptable methods. This is the adapter pattern. (adapter pattern is the simplest and most intuitive mode in all mo
[Mode overview] ---------- by xingoo Pattern intent
If there is already a type, but the interface to be called cannot be implemented through this class. Therefore, convert the existing class to a class that supports interfaces after adaptation.
In other words, it is to program one existing interface to another available interface. Mode Structure

A container is a collection of specific types of objects. The types of containers are divided into ordered containers, container adapters, and associated containers. Ordered containers aggregate a single type of elements into containers, then, these elements are stored and accessed based on their locations.

Adapter Mode definition: Jiuge two incompatible classes together, in a structured pattern, with two identities (adaptee) and adaptor (adapters).Why use Adapter modeWe often encounter the need to combine two classes that are not related to each other, the first solution is to modify the interfaces of the respective classes, but if we do not have the source code, or we do not want to modify the respective int
