High imitation Yahoo weather for Android (2) --- code structure analysis

High imitation Yahoo weather for Android (2) --- code structure analysis

 

 

In this example, six library codes and one master project code are used.

 

Shows the code of one or six databases:

Where

①. MenuDrawer, ViewPagerIndicator, ShowcaseView, and SwipeBack are all well-known open-source libraries on the sidebar menu on Github. I have not made any changes here and I will directly reference them. Thanks for the strength of open-source.

②. PullToRefresh is also a well-known pull-down refresh open-source library on Github. I made some small changes, mainly to add the Yahoo pull-down refresh effect to it. As shown in:

 

③. Weather-lib is the Xiaomi weather source I shared with you earlier. It is only added to the local cache and is not described. For details, see http://blog.csdn.net/way_ping_li/article/details/29669045.

 

2. shows the main code structure:

 

Where:

Com. way. adapter: All adapters, including ListView and ViewPager.

Com. way. beans: where all Java beans are stored.

Com. way. common. util: stores all tool classes, such as network judgment, system tools, and time tools.

Com. way. db: the database management class used in this project. It is a file CityProvider. java, I prefer to use ContentProvider. It is more convenient than directly operating the database. Besides, I can process multiple tables in a database at the same time, but the uri is different. When I switch the case, I just need to judge more.

Com. way. fragment: Fragment used in this project. There is only one file.

Com. way. ui. view: all custom views. It is worth mentioning that TouchDispatchView is the View for allocating touch events, because this Code uses scrollview as the pull-down refresh, and ListView is used to display data, therefore, both views require touch events, and a parent container is required to allocate their touch events.

Com. way. yahoo: the package of all activities.

 

Well, today is the end. We will analyze the following three aspects in detail next time:

①. The main interface is blurred and the background slides.

②. Processing of multiple types of items in ListView and GridView.

③ ViewPager uses fragment cache and optimization.

Thank you!
