Directly in the code to add menu items, to the menu item grouping, etc., this is a more traditional approach, it has some shortcomings.For example, in response to each menu item, we need to use constants to save the ID of each menu item, and so on.For this reason, Android provides a better way to define menu as the resource of the application, and the local support of the resources through Android, which ma
You may still remember that we introduced the Android ListView application in detail in the previous article, which is mainly for visual programming. Here, we will use XML for Android to introduce you to another visual programming method.

Objectivewhen learning the framework layer of Android, Android uses Xmlpullparser to parse the source of XML files. So here's a brief introduction to the use of xmlpullparser.
XmlXML (extensible Markup Language) is the Chinese name for Extensible Markup Language. Marking refers to the computer can understand the information symbols, through such a mark, the comp
In the previous section, we used the Sax method to parse the XML document, which is event-driven. Of course, the Android event mechanism is based on the callback function. In this section, we parse the XML document in another way, which is also event-driven, just like the sax way, which is the pull method. Only the pull-mode read

Android builds an XML parsing framework, androidxml
In our work, we often get data from the server and parse it. The server returns two types of data: json and xml. Json can be parsed using excellent open-source frameworks such as gson or fastjson, which saves a lot of trouble. Generally, we only need to design the bean and then call a single sentence to parse it
