SingleActivityNavigation

A single activity application framework with straightforward navigation controls, allowing seamless movement between fragments through different containers using a single line of code.

How does it work?

Your (single) activity must extend from BaseSingleActivity and all your fragments extend from BaseSingleFragment. Then you can simply move between fragments from either activity or fragment.

// take any fragment(s) of your choosing
val myFragment = MyFragment()

// multiple ways to navigate through back stack
// notice how we can use same fragment and seamlessly put it into any container
navigateBack()
navigateBackTo("fragment name")
navigateBackToRoot()
navigateTo(myFragment)
navigateToRoot(myFragment)
navigateToBottomSheed(myFragment)
navigateToDialog(myFragment)
dismissOpenBottomSheet()
dismissOpenDialog()

Make use of many convenience methods to help you control the state of your app

getCurrentFragment()?.let {
    when (it.fragmentType) {
        // this fragment is root, came into existence with navigateToRoot() call
        FragmentType.ROOT -> TODO()
        // this fragment is default, came into existence with navigateTo() call, no special flags
        FragmentType.DEFAULT -> TODO()
        // this fragment is also default, but was flagged as modal during navigateTo() call
        FragmentType.MODAL -> TODO()
        // this fragment is a dialog, came into existence with navigateToDialog() call
        FragmentType.DIALOG -> TODO()
        // this fragment is a dialog, came into existence with navigateToBottomSheet() call
        FragmentType.BOTTOM_SHEET -> TODO()
    }
}

Let the fragment define behavioural patterns of it's own by overriding open properties:

open val isModal: Boolean
open val mustBeValidToInvokeNavigation: Boolean
open val overridesBackPress: Boolean
open val animationEnter: Int
open val animationExit: Int
open val animationPopEnter: Int
open val animationPopExit: Int

And much more:

• Master/detail implementation support.
• Safe instance state recreation.
• Custom transition animations based on fragment type.
• Make sure to check out example app to help you get started.

Nice! How do I get started?

Make sure root build.gradle repositories include JitPack

allprojects {
    repositories {
        ...
        maven { url 'https://jitpack.io' }
    }
}

And SingleActivityNavigation dependency is added to app build.gradle

dependencies {
    implementation 'com.github.mvojtkovszky:SingleActivityNavigation:$latest_version'
}
