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 {
  compile 'com.github.bkhezry:ExtraMapUtils:v1.2.0' 
}

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

declare ExtraMarker

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

ExtraMarker attributes

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

declare ExtraPolyline

 new ExtraPolylineBuilder()

  .setPoints(latLngs_2)

  .setzIndex(0)

  .setStrokeWidth(10)

  .setStrokeColor(Color.argb(100, 255, 0, 0))

  .build();

ExtraPolyline attributes

UiOption attributes

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

• ...
