Installation
Step 1. Add JitPack repository to your top level build.gradle file
allprojects {
repositories {
...
maven {
url 'https://jitpack.io'
}
}
}
Step 2. Add library dependency to your module build.gradle file
dependencies {
...
compile 'com.jemshit:EliteMvp:2.0.2'
}
Structure
There are 7 base Presenter classes to extend from and 1 base View interface.
- EliteView: empty View interface. Your custom View interfaces must extend this.
- EliteCorePresenter: Presenter interface with only 2 methods (
attachView(V),detachView()). Your custom Presenter can implement this or you can use one of the ready Presenters listed below. - ElitePresenter: Simple Presenter with ready methods (
getView(),isViewAttached(),onDestroy()) for holding View reference. Your custom Presenter can extend this and add additional methods. - EliteRx1Presenter: Simple Presenter that has 2 additional methods (
addToOnAttachSubscriptions(s),addToOnCreateSubscriptions(S)) for adding RxJava 1Subscriptions intoCompositeSubscription. - EliteRx2Presenter: Simple Presenter that has 2 additional methods (
addToOnAttachDisposables(D),addToOnCreateDisposables(D)) for adding RxJava 2Disposables intoCompositeDisposable. - EliteNullViewPresenter: Presenter which returns empty View after View is detached, so no need for
view!=nullcheck. Returned empty View methods does nothing when called, read more about Null Object Pattern here. - EliteNullViewRx1Presenter: Presenter which follows Null Object Pattern and has two
CompositeSubscriptions for RxJava 1Subscriptions. - EliteNullViewRx2Presenter: Presenter which follows Null Object Pattern and has two
CompositeDisposables for RxJava 2Disposables.
