GDirectionsApiUtils

This project aims to simplify the usage of the Google Map Direction Rest Api This project is done to help you using the Google Rest Api Direction : http://maps.googleapis.com/maps/api/directions/json?

How it works, definitly simply. You download the jar (gdirectionsapiutils.jar under GDirectionsApiUtils\bin\ ) in the libs folder of your application (under bin) and use it:

    public class MainActivity extends ActionBarActivity implements DCACallBack{
    /**
     * Get the Google Direction between mDevice location and the touched location using the Walk
     * @param point
     */
    private void getDirections(LatLng startPoint, LatLng endPoint) {
    	GDirectionData.Builder builder = new GDirectionData.Builder(startPoint, endPoint)
    	 										.setMode(Mode.MODE_DRIVING)
    	 										.setAlternative(true)
    	 										.setAvoid(Avoid.AVOID_HIGHWAYS)
    	 										.setLanguage("fr")
    	 										.setUs(UnitSystem.US_METRIC);
    	 GDirectionData data = new GDirectionData.DepartureCreator(builder)
    	 										.setDeparture_time("now")
    	 										.build();
    	 GDirectionsApiUtils.getDirection(this, data);
    }

    /*
     * The callback
     * When the direction is built from the google server and parsed, this method is called and give you the expected direction
     */
    @Override
    public void onDirectionLoaded(List<GDirection> directions) { 
        ArrayList<GDColor> colors = new ArrayList<GDColor>();
    	colors.add(new GDColor(Color.BLACK, BitmapDescriptorFactory.HUE_VIOLET));
    	colors.add(new GDColor(Color.BLUE, BitmapDescriptorFactory.HUE_AZURE));
    	colors.add(new GDColor(Color.YELLOW, BitmapDescriptorFactory.HUE_YELLOW));
    	colors.add(new GDColor(Color.CYAN, BitmapDescriptorFactory.HUE_CYAN));
    	int MAX_COLOR = colors.size();
    	
    	
         for(int i = 0; i < directions.size(); i ++) {
        	ArrayList<GDColor> colors = new ArrayList<GDColor>();
        	colors.add(colorsDirection.get(i % MAX_COLOR));
        	
        	
        	GDirectionMapsOptions.Builder builder = new GDirectionMapsOptions.Builder()
        		.setColors(colors)
        		.setPolylineOptions(new PolylineOptions().width(10).zIndex(5));
        	
        	GDirectionMapsOptions mapOptions = builder.build();
        	
        	GDirectionsApiUtils.drawGDirection(directions.get(i), map, mapOptions);
        }
    }

Snippet

Snippet Simple

To add comment which you want in snippet, you just have to add a formatter when you build your GDirectionMapsOptions

	       GDirectionMapsOptions.Builder builder = new GDirectionMapsOptions.Builder()
        		.setColors(colors)
        		.setPolylineOptions(new PolylineOptions().width(10).zIndex(5))
        		.setFormatter(new FormatterSimple());
        	
       GDirectionMapsOptions mapOptions = builder.build();

And implements this class

	public class FormatterSimple implements IGDFormatter {

		@Override
		public String getTitle(GDPath path) {
			return "Distance :" + path.getDistance();
		}
		
		@Override
		public String getSnippet(GDPath path) {
			return Html.fromHtml(path.getHtmlText()).toString();
		}

		@Override
		public boolean isInfoWindows() {
			return false;
		}

		@Override
		public void setContents(Marker marker, GDirection direction,
				GDLegs legs, GDPath path) {
		}
	};

Custom Snippet

If you want a custom layout for snippet cause you don't like the basic, you can customize this layout by add this code when you get the map :

	map = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map))
		        .getMap();
	map.setInfoWindowAdapter(new InfoWindowAdapter() {
			
			@Override
			public View getInfoWindow(Marker marker) {
				View view = getLayoutInflater().inflate(R.layout.custom_view, null, false);
				
				// get data associate with the marker id in hash map, here a GDPath, see below
				GDPath path = hashMap.get(marker.getId());
				// TODO implement code here
				return view;
			}
			
			@Override
			public View getInfoContents(Marker marker) {
				return null;
			}
		});

Info : you can keep the bubble and replace only the info window contents inside the default info window frame (the callout bubble), return null in getInfoWindow(Marker) and override getInfoContents(Marker) instead.

And build your GDirectionMapsOptions with a new formatter

        GDirectionMapsOptions.Builder builder = new GDirectionMapsOptions.Builder()
        		.setColors(colors)
        		.setPolylineOptions(new PolylineOptions().width(10).zIndex(5).color(Color.BLUE))
        		.setFormatter(new FormatterComplex());
        	
       GDirectionMapsOptions mapOptions = builder.build();

Next implements this class

        public class FormatterComplex implements IGDFormatter {
		
		@Override
		public String getTitle(GDPath path) {
			return "Distance :" + path.getDistance();
		}
		
		@Override
		public String getSnippet(GDPath path) {
			return Html.fromHtml(path.getHtmlText()).toString();
		}

		@Override
		public boolean isInfoWindows() {
			// here the information that we want customize the layout
			return true;
		}

		@Override
		public void setContents(Marker marker, GDirection direction,
				GDLegs legs, GDPath path) {
			// put the data associate with the marker id
			hashMap.put(marker.getId(), path);
		}
	};
