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.
The day before yesterday, a netizen asked about the design mode of the adapter mode (Adapter), said not very good understanding. Can insus.net give a simple example to illustrate. The following animation is the result of insus.net:
The above demo, two lamps of the same specification, requires the input voltage of 15 volts.
LIGHT1 is used directly, while LIGHT2 is using
The examples in this article describe common adapters and custom adapter usage in Android programming. Share to everyone for your reference, specific as follows:
One, adapter.
As the name suggests, is to make some data appropriate, suitable for easy to display on the view. Can be seen as an understanding of interface data binding. The data that it manipulates is usually some more complicated data, such as
(Design mode) Adapter mode, design mode adapter ModeIn the adapter mode, similar to the remote control, other different button functions (interfaces) are combined, and the remote control is used for unified encapsulation to adapt to all buttons. Converts an interface of a class to another interface that the customer wants. The

The adapter mode is a very practical design mode. This article will introduce this design mode through examples.
The purpose of the adapter mode is to convert an interface of a class to another interface that the customer wants.

When the adapter refresh data, it must be able to refresh successfully, and ensure that each refresh changes the data source.
So I did this and wrote in the constructor of the adapter:

Adapter Pattern Definition: Use two incompatible classes Jiuge, belong to the structure mode, need to have adaptee (be fit) and adaptor (adapter) two identity.
Why use Adapter mode
We often run into a combination of two classes that don't have a relationship, the first solution is to modify the interfaces of the respective classes, but if we don't have the sour
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

Container
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.

The adapter object derives from Android.widget.Adapter, which includes constructing the list item control and binding the data item to the list item control.Common adapters are: Array adapter arrayadapter, database adapter CursorAdapter.An example of using an adapter object is as follows:Defining dataString [] data = n
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
Adapter mode (Adapter pattern)IntroducedTransforms 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.ExampleThere is a message entity class that has the insert () and get () methods for its operat
The adapter pattern is to transform the interface of one class into another interface that the client expects, so that two classes that would otherwise not work together because of an interface mismatch can work together.An example of an adapter pattern:Please do a specific class of kittie and implement methods such as Miao (), Catchrat (), run (), sleep (), and so on. To do a puppie interface, requires WAO
Today learning another design pattern, adapter (Adapter) mode, which is a common direction, but with special requirements, is applied to this design pattern. Write here, think of a long time ago, have written an article "ASP." NET Adapter design mode (Adapter) http://www.cnblogs.com/insus/archive/2013/02/04/2891426.htm
According to the msdn webcast courses)
Adaptation: basically, the original incompatible interfaces are converted into compatible interfaces without changing the original implementations.
Gof: to convert an interface of a class to another interface required by the customer, you have to work together the classes that cannot work together due to incompatibility of the original interface.

Defined:The use of two incompatible classes jiuge in a structured pattern requires two identities for adaptee (the adapter) and adaptor (adapters). why use?We 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 interfaces for an application. What to do?Using
