##About DroidMVP is a small Android library to help you incorporate the MVP pattern along with Passive View and Presentation Model (yes, those can be combined together :) ) within your Android project.
##Explanation
Pasive View
A screen and components with all application specific behavior extracted into a controller so that the widgets have their state controlled entirely by controller. - Martin Fowler
-- Presentation Model
Represent the state and behavior of the presentation independently of the GUI controls used in the interface - Martin Fowler
--
#####Model and Presenter In our case a controller will be our presenter, which stores the view state within the Presentation Model. All the state manipulation happens within the Model class itself, but it is the Presenter who initiates those modifications.
#####View Our passive view is the activity or fragment, which will be treated as a widgets' (like TextView, ImageView etc.) container with the ability to present different states driven by the presenter. All user interaction should be routed to the presenter.
##Setup
Add it in your root build.gradle
at the end of repositories:
allprojects {
repositories {
...
maven { url "https://jitpack.io" }
}
}
Add the dependency to your app's build.gradle
dependencies {
compile 'com.github.andrzejchm:DroidMVP:0.1.1'
}
##Composition over inheritance
If by any chance you cannot extend from DroidMVPActivity
or DroidMVPFragment
you can always use the DroidMVPViewDelegate
. Just make sure to bind it with your activity's or fragment's lifecycle the same way the DroidMVPFragment
or DroidMVPActivity
does it.
##Dependency Injection
This library makes it easy to use it with dependency injection frameworks like Dagger. To see how it could be done, check out the Sample project, specifically the BaseFragment
or BaseActivity
