Android MVC

I thank Ben for presenting the Android listview project in such a clear an concise manner. However after introducing the concepts of MVC at the start of the unit, Ben lumped all the code together in 1 big activity plus 1 small view. I was hoping to see an app structured on the mvc pattern (using custom events & messages)... Now THAT would be a real intro to professional android development. eg:

  • Model class is observable
  • View class is observer
  • Controller class (main activity)
    • instantiates model and view
    • binds model and view
    • manages user input

<br>Just my 2cents worth ... Ron B, Australia.

Hi Ron,

I do want to create more advanced MVC apps in the future. The Crystal Ball app is meant for total beginners, though, so I don't want to overwhelm students with too many details. The MVC stuff in that project is simply a gentle introduction to the concepts. :smile:

Great feedback and advice, though. I will definitely cover more professional-grade stuff in the future!

A quick update on MVC android apps.

As an android noob but experienced mvc developer in other languages, I just had to give this a go myself. Using the Observer design pattern, I developed a MVC version of Ben's BlogReader app and it turned out to be much easier than I originally thought. Any feedback is welcome.

Here is a link to the project if anyone is interested: BlogMVC.zip Take a look how clean the controller (MainActivity.java) ended up.

Note: I do not use eclipse (ADT) but it should build OK. I'm a Linux guy and use Netbeans IDE or Geany/Gradle for android development.
