A Fragment example, build with ReKotlin and ReKotlin-Router
- Clone this repository
- Open in android studio.
- Build & Run.
You can dispatch the actions that invoke the Fragments similar to Activity .
val routes = arrayListOf(mainActivityRoute, backStackActivityRoute, oneFragmentRoute) val action = SetRouteAction(route = routes) val actionData = SetRouteSpecificData(route= routes,data = FragmentDataValue(activity, true)) mainStore.dispatch(actionData) mainStore.dispatch(action)The function SetRouteSpecificData passes the data to Router to create the fragment.
The signature of FragmentDataValue looks like
class FragmentDataValue(val activity: WeakReference<AppCompatActivity>, val addToBackStack: Boolean)We need to pass the WeakReference of the activity.
You should override the functions to create the Fragments
override fun pushRouteSegment(routeElementIdentifier: RouteElementIdentifier, animated: Boolean, completionHandler: RoutingCompletionHandler): Routable { when (routeElementIdentifier) { oneFragmentRoute -> { return RoutableHelper.backStackFragmentRoutable(fragment = OneFragment(), tag = "OneFragment") } twoFragmentRoute -> { return RoutableHelper.backStackFragmentRoutable(fragment = TwoFragment(), tag = "TwoFragment") } } }Let's look at the function backStackFragmentRoutable
fun backStackFragmentRoutable(fragment: Fragment,tag: String): FragmentRoutable { val currentRoute = mainStore.state.navigationState.route val intentData: FragmentDataValue = mainStore.state.navigationState .getRouteSpecificState<FragmentDataValue>(currentRoute)!! val activity = intentData.activity.get()!! val addToBackStack = intentData.addToBackStack addFragment(fragment, activity, addToBackStack, tag,R.id.container_frame_back_stack) //changeFragment(fragment,activity,addToBackStack,tag,R.id.container_frame_back) return FragmentRoutable(activity.applicationContext) }It does the following
- get the current route from
navigationState - From the current route, get the fragment's
intentData - With the
intentData, get the activity from itsWeakReferenceand Boolean value whether to add to stack. - Call the function
addFragment, helper method to create the fragment.
