Mappls GeoFence View

Introduction

A ready to use UI Widget to create/edit GeoFence in an Android application.

Add the dependency

Add below dependency in app level build.gradle file

implementation 'com.mappls.sdk:geofence-ui:1.0.0'

Add GeoFence View to your application

You can add GeoFence view in two ways

  1. Using XML
  2. Using Java

Using XML

<com.mappls.sdk.geofence.ui.views.GeoFenceView  
  android:id="@+id/geo_fence_view" 
  android:layout_width="match_parent"  
  android:layout_height="match_parent" />

Callbacks getting from GeoFence View

Implement from GeoFenceViewCallback interface 1. void onGeoFenceReady(MapplsMap mapplsMap): When map is loaded successfully 2. void geoFenceType(GeoFenceType geofenceType): When toggle between geofence type 3. void onCircleRadiusChanging(int radius): When radius of the circle changes 5. void onUpdateGeoFence(GeoFence geoFence): On update geofence data 6. void hasIntersectionPoints(): When Polygon is intersecting

To change the circle Radius

On circle radius changing:

geoFenceView.onRadiusChange(progress)

On circle radius change finish

geoFenceView.radiusChangeFinish(seekBar?.progress!!)

Toggle draw polygon enable/disable

geoFenceView.enablePolygonDrawing(isChecked)

Toggle Geofence type

To draw circle Geofence

geoFenceView.drawCircleGeoFence()

To draw polygon Geofence

geoFenceView.drawPolygonGeofence()

To draw Rectangle Geofence

geoFenceView.drawQuadrilateralGeofence()

Restrict number of points in a polygon

geofenceView.setMaxAllowedEdgesInAPolygon(12);

Callback when user tries to add more than restricted points in a polygon

geoFenceView.setOnPolygonReachedMaxPointListener(new OnPolygonReachedMaxPointListener() {
            @Override
            public void onReachedMaxPoint() {
                   //show a message to the user
            }
        })

Auto correct self intersecting polygon

geofenceView.simplifyWhenIntersectingPolygonDetected(true);

Set Normal/Rectangle Polygon
