# Getting Directions Now we have a simple map with a floor selector where you can search for locations. When finishing this step you'll be able to create a directions between two points and change the transportation mode. ### Get Directions Between Two Locations[​](https://docs.mapsindoors.com/getting-started/android/v3/directions#get-directions-between-two-locations) After having created our list of search results, we have a good starting point for creating directions between two Locations. Since our search only supports a single search, we will hardcode a Location's coordinate into our app, and use that as the basis for our Origin. Then we'll create a route, navigate to a view of the navigation details, and show a route on the map from the Origin to the Destination. We have already created a point in the basic example, called `mUserLocation` to use as a starting point for directions on `MapsActivity` * Java * Kotlin ``` private Point mUserLocation = new Point(38.897389429704695, -77.03740973527613,0); ``` Now we will create a method that can generate a route for us with a Location (picked from the search list). Start by implementing `OnRouteResultListener` to your MapsActivity. * Java * Kotlin ``` public class MapsActivity extends FragmentActivity implements OnMapReadyCallback, OnRouteResultListener ``` Implement the `onRouteResult` method and create a method called `createRoute(MPLocation mpLocation)` on your `MapsActivity`. Use this method to query the `MPRoutingProvider`, which generates a route between two coordinates. We will use this to query a route with our hardcoded `mUserLocation` and a point from a MPLocation. To generate a route with the `MPLocation`, we start by creating an `onClickListener` on our search `ViewHolder` inside the `SearchItemAdapter`. In the method `onBindViewHolder` we will call our `createRoute` on the `MapsActivity` for our route to be generated. * Java * Kotlin [SearchItemAdapter.java](https://github.com/MapsPeople/MapsIndoors-Getting-Started-Android/blob/master/app/src/main/java/com/example/mapsindoorsgettingstarted/SearchItemAdapter.java#L37-L40) ``` public void onBindViewHolder(ViewHolder holder, int position) { ... holder.itemView.setOnClickListener(view -> { mMapActivity.createRoute(mLocations.get(position)); //Clearing map to remove the location filter from our search result mMapActivity.getMapControl().clearMap(); }); ... } ``` We start by implementing logic to our createRoute method to query a route through `MPRoutingProvider` and assign the onRouteResultListener to the activity. When we call the `createRoute` through our `onClickListener` we will receive a result through our `onRouteResult` implementation. When we receive a result on our listener, we render the route through the `MPDirectionsRenderer`. We create global variables of the `MPdirectionsRenderer` and `MPRoutingProvider` and create a getter to the `MPDirectionsRenderer` to access it from *fragments* later on. * Java * Kotlin [MapsActivity.java](https://github.com/MapsPeople/MapsIndoors-Getting-Started-Android/blob/master/app/src/main/java/com/example/mapsindoorsgettingstarted/MapsActivity.java#L218-L267) ``` void createRoute(MPLocation mpLocation) { if (mpRoutingProvider == null) { mpRoutingProvider = new MPRoutingProvider(); mpRoutingProvider.setOnRouteResultListener(this); } mpRoutingProvider.query(mUserLocation, mpLocation.getPoint()); } @Override public void onRouteResult(@Nullable Route route, @Nullable MIError miError) { ... //Create the MPDirectionsRenderer if it has not been instantiated. if (mpDirectionsRenderer == null) { mpDirectionsRenderer = new MPDirectionsRenderer(this, mMap, mMapControl, i -> { //Listener call back for when the user changes route leg. (By default is only called when a user presses the RouteLegs end marker) mpDirectionsRenderer.setRouteLegIndex(i); mMapControl.selectFloor(mpDirectionsRenderer.getCurrentFloor()); }); } //Set the route on the Directions renderer mpDirectionsRenderer.setRoute(route); //Create a new instance of the navigation fragment mNavigationFragment = NavigationFragment.newInstance(route, this); //Add the fragment to the BottomSheet addFragmentToBottomSheet(mNavigationFragment); //As camera movement is involved run this on the UIThread runOnUiThread(()-> { //Starts drawing and adjusting the map according to the route mpDirectionsRenderer.initMap(true); ... }); } ``` See the full implementation of these methods here: [MapsActivity.java](https://github.com/MapsPeople/MapsIndoors-Getting-Started-Android/blob/master/app/src/main/java/com/example/mapsindoorsgettingstarted/MapsActivity.java#L218-L267) or [MapsActivity.kt](https://github.com/MapsPeople/MapsIndoors-Getting-Started-Android-Kotlin/blob/main/app/src/main/java/com/example/mapsindoorsgettingstartedkotlin/MapsActivity.kt#L185-L225) Now we will implement logic to our `NavigationFragment` that we can put into our BottomSheet and show the steps for each route, as well as the time and distance it takes to travel the route. Here we'll use a `viewpager` to allow the user to switch between each step, as well as display a "close" button so we are able to remove the route and the bottom sheet from the activity. We will start by making a getter for our `MPDirectionsRenderer` that we store on `MapsActivity`: * Java * Kotlin [MapsActivity.java](https://github.com/MapsIndoors/MapsIndoors-Getting-Started-Android/blob/master/app/src/main/java/com/example/mapsindoorsgettingstarted/MapsActivity.java#L127-133) ``` public MPDirectionsRenderer getMpDirectionsRenderer() { return mpDirectionsRenderer; } ``` Inside the `NavigationFragment` we will implement logic to navigate through Legs of our Route. * Java * Kotlin [NavigationFragment.java](https://github.com/MapsPeople/MapsIndoors-Getting-Started-Android/blob/master/app/src/main/java/com/example/mapsindoorsgettingstarted/NavigationFragment.java) ``` public class NavigationFragment extends Fragment { private Route mRoute; private MapsActivity mMapsActivity; ... @Override public void onViewCreated(@NonNull View view, @Nullable Bundle savedInstanceState) { RouteCollectionAdapter routeCollectionAdapter = new RouteCollectionAdapter(this); ViewPager2 mViewPager = view.findViewById(R.id.view_pager); mViewPager.setAdapter(routeCollectionAdapter); mViewPager.registerOnPageChangeCallback(new ViewPager2.OnPageChangeCallback() { @Override public void onPageSelected(int position) { super.onPageSelected(position); //When a page is selected call the renderer with the index mMapsActivity.getMpDirectionsRenderer().setRouteLegIndex(position); //Update the floor on mapcontrol if the floor might have changed for the routing mMapsActivity.getMapControl().selectFloor(mMapsActivity.getMpDirectionsRenderer().getCurrentFloor()); } }); ... //Button for closing the bottom sheet. Clears the route through directionsRenderer as well, and changes map padding. closeBtn.setOnClickListener(v -> { mMapsActivity.removeFragmentFromBottomSheet(this); mMapsActivity.getMpDirectionsRenderer().clear(); }); //Next button for going through the legs of the route. nextBtn.setOnClickListener(v -> { mViewPager.setCurrentItem(mViewPager.getCurrentItem() + 1, true); }); //Back button for going through the legs of the route. backBtn.setOnClickListener(v -> { mViewPager.setCurrentItem(mViewPager.getCurrentItem() - 1, true); }); //Describing the distance in meters distanceTxtView.setText("Distance: " + mRoute.getDistance() + " m"); //Describing the time it takes for the route in minutes infoTxtView.setText("Time for route: " + TimeUnit.MINUTES.convert(mRoute.getDuration(), TimeUnit.SECONDS) + " minutes"); } public class RouteCollectionAdapter extends FragmentStateAdapter { ... } } ``` See the full implementation of `NavigationFragment` and the accompanying adapter here: [NavigationFragment.java](https://github.com/MapsPeople/MapsIndoors-Getting-Started-Android/blob/master/app/src/main/java/com/example/mapsindoorsgettingstarted/NavigationFragment.java#L31-L117) or [NavigationFragment.kt](https://github.com/MapsPeople/MapsIndoors-Getting-Started-Android-Kotlin/blob/main/app/src/main/java/com/example/mapsindoorsgettingstartedkotlin/NavigationFragment.kt#L18-L105) We will then create a simple textview to describe each step of the Route Leg in the `RouteLegFragment` for the `ViewPager`: * Java * Kotlin [RouteLegFragment.java](https://github.com/MapsPeople/MapsIndoors-Getting-Started-Android/blob/master/app/src/main/java/com/example/mapsindoorsgettingstarted/RouteLegFragment.java) ``` public class RouteLegFragment extends Fragment { private RouteLeg mRouteLeg; ... @Override public void onViewCreated(@NonNull View view, @Nullable Bundle savedInstanceState) { super.onViewCreated(view, savedInstanceState); //Assigning views TextView fromTxtView = view.findViewById(R.id.from_text_view); String stepsString = ""; //A loop to write what to do for each step of the leg. for (int i = 0; i < mRouteLeg.getSteps().size(); i++) { RouteStep routeStep = mRouteLeg.getSteps().get(i); stepsString += "Step " + (i + 1) + routeStep.getManeuver() + "\n"; } fromTxtView.setText(stepsString); } } ``` See the full implementation of the fragment here: [RouteLegFragment.java](https://github.com/MapsPeople/MapsIndoors-Getting-Started-Android/blob/master/app/src/main/java/com/example/mapsindoorsgettingstarted/RouteLegFragment.java#L23-L57) or [RouteLegFragment.kt](https://github.com/MapsPeople/MapsIndoors-Getting-Started-Android-Kotlin/blob/main/app/src/main/java/com/example/mapsindoorsgettingstartedkotlin/RouteLegFragment.kt#L12-L44) ### Change Transportation Mode[​](https://docs.mapsindoors.com/getting-started/android/v3/directions#change-transportation-mode) In MapsIndoors, the transportation mode is referred to as **travel mode**. There are four travel modes, **walking**, **bicycling**, **driving** and **transit** (public transportation). The travel modes generally applies for outdoor navigation. Indoor navigation calculations are based on **walking** travel mode. To swap Travel Modes you set the Travel Mode before making a query for the route: * Java * Kotlin ``` void createRoute(MPLocation mpLocation) { //If MPRoutingProvider has not been instantiated create it here and assign the results call back to the activity. if (mpRoutingProvider == null) { mpRoutingProvider = new MPRoutingProvider(); mpRoutingProvider.setOnRouteResultListener(this); } mpRoutingProvider.setTravelMode(TravelMode.WALKING); //Queries the MPRouting provider for a route with the hardcoded user location and the point from a location. mpRoutingProvider.query(mUserLocation, mpLocation.getPoint()); } ``` Expected result: ![An animation showing the desired behaviour of this tutorial](https://docs.mapsindoors.com/img/getting-started/android_directions_gif.gif) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
