Android learning notes-Adapter basics, android-adapterThis section introduces
Starting from this section, we will talk about the UI control that deals with the Adapter. It is very important to understand and learn how to use this Adapter. The Adapter is an intermediate bridge used to help fill data, to put it simply, v
1, Overview: (1) The adapter mode of the object is the origin of the various modes:(2) adapter mode:The adapter pattern transforms the interface of a class into another interface representation that the client expects to beeliminate the compatibility problems of classes caused by interface mismatch, mainly divided into three categories:Adapter mode for the ① cl
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
1. ConceptAdapter is an adapter interface that connects back-end data to the front-end display and is an important link between data and the UI (View). In common View (Listview,gridview) and other places need to use adapter. such as the intuitive expression of data, Adapter, view the relationship between the three:All adapter
Usually we often encounter this situation, there are two of ready-made classes, there is no connection between them. But we now want to use one of the methods of the class. At the same time, you want to use a different class method. There is one solution. Changes to their respective interfaces. But this is the last thing we want to see. This time, adapter mode will come in handy.There are three ways of adapter
The function of Adapter pattern is to convert the interface without changing the function. Adapter is divided into two categories, one is Object Adapter, and the other is class Adapter. Because the implementation of class Adapter requires multiple inheritance, and Java does
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.

I haven't written any articles for more than half a month. It's mainly because there are a lot of messy things in my senior high school, hitting the wall for a job. We also blame ourselves for the poor strength, but also for the lack of practical experience, which is difficult to attract HR interest. So I am still making a small advertisement here. I hope any one of
To do the project encountered, tortured me will be nearly two days, today to share the experience, so that we can not go a little detour, good, simple to say what is the Android adapter, how to define, how to increase the reusability of the adapter, how to reduce the program's couplingAdapter as the name implies is used to do the adaptation, but he is how to adapt, the mechanism is what, the role of what, g
We often encounter this situation, there are two of ready-made classes, there is no connection between them, but we now want to use one of the methods of the class, but also want to use another class method.

Adapter mode introduction:

In computer programming, the
Adapter Mode related source code:slf4j-1.6.1, hibernate-3.6.7We all know that. Log4j is a widely used log tool, in addition to that. Sun also has its own log tool in the JDK, which is java.util.logging.Logger.There are, of course, some other logging tools.A variety of logging tools function and use similar, generally include debug, info, warn, error and other log level methods, but did not implement a common interface. This is not like JDBC. Although

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

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
