Create a Search Experience with MapsIndoors - Part 2

This is part 2 of the tutorial of creating a simple search experience using MapsIndoors. In Part 1 we created the search Fragment. Now we will create the "main" controller displaying the map and eventually the selected location.

Start by creating a Fragment

public class SearchMapFragment extends Fragment

Add a GoogleMap and a MapControl to the class

MapControl mMapControl;
GoogleMap mGoogleMap;

Add other needed views for this example

SupportMapFragment mMapFragment;
Button searchButton;
Location locationToSelect = null;

A listener to report the click on the search Button to the activity

private OnFragmentInteractionListener mListener;

The lat lng of the Venue

static final LatLng VENUE_LAT_LNG = new LatLng( 57.05813067, 9.95058065 );

Setting the API key to the desired Solution

if( !MapsIndoors.getAPIKey().equalsIgnoreCase( getString( R.string.mi_api_key ) ) )
{
    MapsIndoors.setAPIKey( getString( R.string.mi_api_key ) );
}
if( getActivity() == null )
{
    return;
}

Instanciate the MapControl object

mMapControl = new MapControl( getActivity(), mMapFragment, mGoogleMap );

• init the MapControl object which will sync data.
• When the init is done, if the 'locationToSelect' is not null we call the 'mMapControl.selectLocation()' to select the desired location otherwise select a floor

mMapControl.init( miError -> {
    if( miError == null )
    {
        Activity context = getActivity();
        if( context != null )
        {
            context.runOnUiThread(() -> {
                mGoogleMap.animateCamera( CameraUpdateFactory.newLatLngZoom( VENUE_LAT_LNG, 20f ) );
                if( locationToSelect != null )
                {
                    mMapControl.selectLocation( locationToSelect );
                    locationToSelect = null;
                }
                else
                {
                    mMapControl.selectFloor( 1 );
                }
            });
        }
    }
});

A public method to select a location

public void selectLocation(Location loc){
    locationToSelect = loc;
}
