mvvm vs mvp

Preface descriptionIn the actual combat project and study to summarize the Android Terminal Project frameworkIncludes MVC, MVP, MVVM, primarily for mobile AndroidThis article uses the Android platform user login As an example to describe the architecture pattern in codeThe code is primarily understood, so it may not be complete, as it removes some of the streamlining and convenience instructionsDirectory1.

MVC: The user's request will first arrive at the controller, where the Controller obtains data from the model, selects the appropriate view, and presents the processing result to the view; MVP: The user's request will first arrive at the view, and the view will pass the request to the specific presenter. After the presenter obtains data from the model, it will pass the processing result to the view through the interface.

worrying about the model layer's need to change the test, or you can change the model layer implementation to another way, regardless of the view problem.While MVVM is also an improvement to MVC, which is also about view and model decoupling, but the form is different, it needs to be noted that there is a ViewModel framework to support the interaction between view and ViewModel. And the function of the ViewModel layer is the business logic, when bind

1.MVCFeatures: unidirectional　Accept the instruction: 1. Pass view, then pass to controller;2. Directly through the controller2.MVP, change controller to PresenderFeatures: bidirectional communication, presenter processing all logic, view thinning. 3.MVVMFeatures: similar to the MVP, the use of two-way binding, view changes automatically reflected in the ViewModel. 　Excerpt from: http://www.ruanyifeng.com/b

, and of course, we don't have to rely on the popular MVC framework at all. Let's look at a picture below:MVC's view works directly with the model, and the controller only acts as a "bridge", which is responsible for forwarding the view request to the model and then notifying the view of the end of the model processing message. A controller is a message dispatcher. Without passing data (business results), the controller is used to decouple the view and model, specifically to separate the UI from

Mvc: Definition of MVC:M: Business logic processing. "Business model"V: The part that handles the display of the data. "such as XML layout file"C:activity handles user interaction issues. "Activity in MVC plays the role of C." Features of MVC:① and low coupling.②, scalability is good.③ and module responsibilities are clearly divided. An example of MVC is detailed: Summarize:①, the use of MVC design patterns, so that the project has a very good scalability and maintenance.②, contro

common presentation modes: (1) MVC: Model-View-controller, which forcibly separates input, processing, and output of applications.
