?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.

Basic of ListView-data adapter resolution and listview AdapterData adapter: Purpose: Fill in complex data (array, linked list, database, set, etc.) on the specified view interface.ArrayAdapter (array adapter): used to bind a single data formatArray Source: can be a set or ArrayArrayAdapter (context, the layout file and data source corresponding to each list item

Explain: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.Solve the problem:What is needed is, but cannot be used, and cannot be modified in a short time. That is, make a function suitable for different environments.In the development, the system data, behavior are matched, but the interface does not match, you can consider the adapter.It is desirable to r

Here is a "finger-round" example to illustrate the principle of adapter mode and simple application, this example from Java and schema. 1. Class Diagram 2.

One system wants to use another system's data source, but the data source format does not meet its own requirements, which can be used in adapter modeOne example: The data provided by the personnel system returns the map type, but the financial system needs a List type of dataData sources provided by the personnel system:1 ImportJava.util.HashMap;2 ImportJava.util.Map;3 4 Public classpeople {5 PublicMapGetorgname () {6MapNewHashmap();7Map.put (1

What I do is what I love and do what I do, in this way, both of them can be done. The following code is used: Reading: The old lady thought she was going to study. She actually went o

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

What is the role of adapter? In fact, it is a bridge between the view interface and the data. We can be seen as an understanding of interface data binding, and the data it manipulates are generally more complex data, such as arrays, lists, databases, collections, etc.The commonly used adapters are:(1) arrayadapter; array as the data source, filled with arrayadapter(2) Simpleadapter; list as a data source, populated with Simpleadapter(3) Simplecursorad

Adapter Mode: Converts the interface of a class into another interface that the customer expects. Adapters allow classes that are incompatible with the original interface to work together.Direct. The following is the class diagram for the object adapter. Because Java does not support multiple inheritance. So this is how the Java adapter is implemented.Combining H

What is adapter mode?The adapter mode makes it possible for those classes that cannot work together because of incompatible interfaces.Simply put, it is the things that need to be in front of, do not use, and short time can not transform it, so we will find a way to adapt it. The adapter pattern is primarily used in situations where you want to reuse some existin
