Tip Calculator - A recap

Edit

Over the course of these articles, we’ve covered the complete Tip Calc app on 5 platforms from one shared PCL code library using Mvvm.

Summary

I hope this was simple and easy to follow…

Just to recap what we did:

  • For the core PCL library, we:
  • created a Profile 259 library
  • added some MvvmCross PCL libraries
  • added our services - the Calculator
  • added our TipViewModel which exposed properties
  • added our App which wired the services together and defined an IMvxAppStart
  • For each platform, we generally went through a process like:
  • created a platform specific project
  • added some MvvmCross PCL libraries
  • added some MvvmCross platform specific libraries
  • added a Setup class which would initialise everything
  • modified the platform-specific Application to call Setup
  • created a Views folder
  • added a platform specific View
  • changed that View base class to something beginning with Mvx
  • added a public new TipViewModel ViewModel to link the View to the ViewModel
  • modified the XML for that View to add the UI fields
  • modified those UI fields to add databinding to the ViewModel properties
  • pressed ‘Run’ :)
  • considered some ways that the UI could be improved using platform-specific UI techniques

Generally, these same steps are what you’ll follow for each MvvmCross application you want to make.

We’ll cover more advanced topics in future articles.
