The first few introduced the design pattern characteristics and explained in detail 4 kinds of creation pattern, the creation pattern is responsible for how to produce the object instance, next talk about the structure pattern. first, what is the structural model ? Structural pattern is the internal structure and external combination of analytic classes and objects, and solves the coupling problem between modules by optimizing the program structure. ii. types of structural patterns :

Custom ListView adapter and listview Adapter Inherit the BaseAdapter class Override the following four methods: @ Override public int getCount () {return users. size () ;}@ Override public Object getItem (int position) {return users. get (position) ;}@ Override public long getItemId (int position) {return (User) getItem (position )). getId () ;}@ Override public View getView (int position, View convertView,

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

An adapter is a bridge between data in Android and view view, which is the function of displaying data through the adapter to the corresponding view view.At work, when using a ListView to do adapter data, some people must have met, how to optimize efficiency, but also the situation of duplication of data, how to avoid duplication of data and can improve the size

PHP Tutorial Design mode builder mode and adapter (adapter mode) Adapter mode** Convert the interface of a class to another interface that the customer expects, and those classes that are not compatible to work together can work together Builder model** Separate the build of a complex object from its representation, and use the same build process to create diff

?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

of laws that can absorb the internal forces of others while not losing the internal forces of others and will absorb the skill for their own use? Oh, perhaps is looking at this article of you to invent this set of laws, will also become the same as Zhang a generation of Guru (see I said that cut ...) ）。 In fact, in software design, as in the case of this story in general, for example, there is a design of Class A (there is a method of public void Aa () {}), we need to call him in the current sy

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
