Setup

1. Provide the gradle dependency

Add it in your root build.gradle at the end of repositories:

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

Add the dependency:

dependencies {
	implementation 'com.github.bkhezry:ExtraMapUtils:1.2.2'
}

2. Add your code

add MapView to UI layout

<com.google.android.gms.maps.MapView
	android:id="@+id/mapLite"
	android:name="com.google.android.gms.maps.MapFragment"
	android:layout_width="match_parent"
	android:layout_height="300dp"
	app:liteMode="true"
	app:mapType="normal" />

new ViewOptionBuilder()
	.withStyleName(ViewOption.StyleDef.RETRO)
	.withCenterCoordinates(new LatLng(35.6892, 51.3890))
	.withMarkers(AppUtils.getListExtraMarker())
	.withPolygons(
		AppUtils.getPolygon_1()
	)
	.withPolylines(
		AppUtils.getPolyline_2(),
		AppUtils.getPolyline_4()
	)
	.withForceCenterMap(false)
	.build();

after declaring the ViewOption, add this code for showing elements on the MapView

 MapUtils.showElements(viewOption, googleMap, getActivity());

ViewOption attributes

Name	Type	Default	Description
title	String	@NullAble	use in demo as CardView tile
centerLatLng	LatLng	@NullAble	center of Map
forceCenterMap	boolean	false	force map moving to centerLatLng point
mapsZoom	float	14	zoom of map when map moving to centerLatLng
markers	ExtraMarker	@NullAble	list of ExtraMarker that showing on Map
polygons	ExtraPolygon	@NullAble	list of ExtraPolygon that showing on Map
polylines	ExtraPolyline	@NullAble	list of ExtraPolyline that showing on Map
isListView	boolean	false	when using utils in ListView this parameter should be true. because fixing zoom of bounded map
styleName	StyleDef	DEFAULT	style of google map

declare ExtraMarker

new ExtraMarkerBuilder()
	.setName("Start")
	.setCenter(latLngs_3[0])
	.setIcon(icons_2[0])
	.build()

ExtraMarker attributes

Name	Type	Default	Description
name	String	@NullAble	label of Marker
center	LatLng	@NoneNull	center of Marker
icon	int	@NoneNull	icon of marker

delare ExtraPolygon

new ExtraPolygonBuilder()
	.setPoints(latLngs_1)
	.setzIndex(0)
	.setStrokeWidth(10)
	.setStrokeColor(Color.argb(100, 0, 0, 0))
	.setFillColor(Color.argb(100, 200, 200, 200))
	.build();

ExtraPolygon attributes

Name	Type	Default	Description
points	LatLang[]	@NoneNull	list of point
fillColor	int	none color	color of polygon filling
uiOptions	UiOption	@NoneNull	some parameter of polygon

declare ExtraPolyline

 new ExtraPolylineBuilder()
                .setPoints(latLngs_2)
                .setzIndex(0)
                .setStrokeWidth(10)
                .setStrokeColor(Color.argb(100, 255, 0, 0))
                .build();

ExtraPolyline attributes

Name	Type	Default	Description
points	LatLang[]	@NoneNull	list of point
uiOptions	UiOption	@NoneNull	some parameter of polyline

UiOption attributes

Name	Type	Default	Description
strokeColor	int	Color.BLACK	line color
strokeWidth	int	10	width of line
zIndex	int	0	zIndex of polyline or polygon
strokePattern	StrokePatternDef	Default	stroke pattern of line

getArea() method in ExtraPolygon return Area of polygon in square meters. getLength method in ExtraPolyline return Length of polyline in meters.

add GeoJson to ViewOption

new ViewOptionBuilder()
	    .withTitle("GeoJson")
	    .withGeoJson(context.getString(R.string.geo_json_url))
	    .withStyleName(ViewOption.StyleDef.DEFAULT)
	    .withGeoJsonEventListener(new onGeoJsonEventListener() {
		@Override
		public void onFeatureClick(Feature feature) {
		    //Do more things.
		}

		@Override
		public void onGeoJsonLoaded(GeoJsonLayer geoJsonLayer) {
		    AppUtils.addColorsToMarkers(geoJsonLayer);
		}
	    })
	    .withIsListView(true)
	    .build();

Todo

• clustering support for markers
• add GeoJson & KML layers to map
• add more demo for mixed elements.
• javadoc
