Java Adapter mode (Adapter Mode)Adapter mode definition: Used together two incompatible classes. It is a structural mode and requires two identities: Adaptee and Adaptor. Why do we often encounter the combination of two unrelated classes when using the adapter mode? The first solution is to modify the interfaces of the
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

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:
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.

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. Intention
Converts an interface of a class to another interface that the customer wants. The A d a p t e r mode makes those classes that cannot work together due to interface incompatibility work together.
2. Applicability
Use the d a p te r mode in the following cases
• You want to use an existing class, and its interface does not meet your needs.
• You want to create a reusable class that can work collaboratively with other unrelated classes or unforeseen classes (that is, classes that may
When we do Android list development, we sometimes encounter problems like this:Java.lang.IllegalStateException:The content of the adapter have changed but ListView do not receive a notification. Make sure the content of your adapter are not modified from a background thread, but only from the UI thread. Make sure your adapter calls notifydatasetchanged () while i

DefinedAdapter Mode (Adapter) is the transformation of an interface (a method or a property) of a Class (object) into another interface (method or property) that the customer wishes, and the adapter pattern makes it possible for those classes (objects) that would otherwise not work together because of incompatible interfaces to work. Express Wrapper (wrapper).
