Occasionally, in a QQ group, I saw a student asking about this platform, and I just logged in and looked at it. Just happened to be a bottleneck in self-learning android. I wrote a news app based on this platform. The platform is free, and the explanation is very detailed. Sometimes it is slow to open for the first time, try a few more times, etc. This is the address of the platform:
http://www.tngou.net/
The following is the interface:
http://www.tngou.net/blog/show/1296
Tribute to seniors who provide free platforms!
I have already implemented features are:
read the latest news list (the list of news recently, it seems a long time but did not update the original can be read, to learn enough.)
To read news content
to read comments relevant
account registration, Account login, personal information settings (here lazy, jump to the website directly after clicking the personal information settings ...)
This project is suitable for novice exercises, involving data interaction and data analysis with the server. The disadvantage is that the interface is more frustrating and there is no framework at all, so the more the code is written, the higher the degree of coupling, and the logic is more confusing.
Because the picture can only be 2M, so only a part was recorded.
Project structure:
Account is mainly for account login, registration, and personal information modification. The
Adapter contains two adapters, one is an adapter for comment lists, and the other is an adapter
for news lists. GetContext is used to obtain a Context object like
ImageCache. Image cache, planned to use pictures Cache to local, no need to go to the server to download pictures every time you open the app, the function has not added
JSON JSON data analysis
CommentsActivity Comment list related logic operations
ItemActivity News content interface related logic operations
MainActivity theme frame logic events and news list logic events, most of the UI refresh
RecyclerItem news category contains a piece of basic information about news
There are detailed comments in each class, not much to say. MainActivity is posted below:
