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
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

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.

However, as wireless Internet access technology becomes more and more popular, the "wireless Internet access" era has quietly come to our side. The desire to break through the limitations of Network cables and free Internet access anytime and anywhere has contributed to the growth of the wireless network card market. Now, whether wireless Internet access is available has become one of the main indicators for consumers to determine whether a c
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

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
?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;

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

The holes that use Holder in the Adapter, and the Adapter uses Holder
When using the GridView and ListView, Zookeeper usually uses Holder to cache each item in the Adapter to improve efficiency. However, if the Holder is not used properly, this caching mechanism will lead to many unexpected problems, I would like to sum up my experience to avoid further attacks i
