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
Today, we're going to comb the adapter pattern for Java design mode. Adapter, think of our usual use of the power adapter to know, is to put two incompatible things straightened out, can contact each other. Also in Java, is to let two need to coordinate the class, through the adapter to coordinate the line, that is,
Design Concept and Mode 2 adapter mode and thought adapter Mode1. What is the adapter mode?
The adapter mode is a transitional mode used to communicate two incompatible things and exchange information.2. Purpose of the adapter Mode

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.
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 order of elemen
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

In real life, we also often use adapters, which are similar to the commonly used computer adapters. You don't need to charge the adapters, but we found that the computer adapters are also qualified, first, you have to have electricity. If there is no electricity, there will be no Adapter. Second, you have to have
