A library to simplify the work with Android Google Map

AndExMapHelper

AndExMapHelper is a library to simplify the work with Android Google Map. This library has many features such as:

• get and show current location
• add one or many markers on map
• manage markers icon with a concept called status. you can define an arbitrary count of status that each status has its own related icon. you can change status of markers which also changes the icon of marker.
• remove a marker from map
• draw circle and polygon on map
• filter markers on map by status and also distance
• ...

This library is also available at JitPack.io

this library is compatible to androidx

Setup

The simplest way to use this library is to add the library as dependency to your build.

Gradle

Step 1. Add it in your root build.gradle at the end of repositories:

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

Step 2. Add the dependency

// builde.gradle(project level)
dependencies {    
	classpath 'com.google.gms:google-services:4.2.0'
}

// builde.gradle(app level)
dependencies {    
    implementation 'com.github.salehyarahmadi:AndExAlertDialog:v1.0.1'
    implementation 'com.google.android.gms:play-services-maps:17.0.0'
    implementation 'com.google.android.gms:play-services-location:17.0.0'
}

Step 3. Add your google map api key to AndroidManifest.xml file

<meta-data
    android:name="com.google.android.geo.API_KEY"
    android:value="YOUR-GOOGLE-MAP-API-KEY" />

Usage

Permissions

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

XML

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

<fragment
    android:id="@+id/map"
    android:name="com.google.android.gms.maps.SupportMapFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity" />
    
</RelativeLayout>

Java

Note that before using this library's methods, be sure to get location permissions from the user

@Override
protected void onCreate(Bundle savedInstanceState) {
    SupportMapFragment supportMapFragment = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
    supportMapFragment.getMapAsync(this);
}

@Override
public void onMapReady(GoogleMap googleMap) {
    // initialize map
    AndExMapHelper.Init(context, googleMap,locationListener, minTimeToUpdateLocation, minDistanceToUpdateLocation);
        
    // define statuses and related marker icons for markers
    AndExMapHelper.setStatuses(new HashMap<String, Integer>(){{
        put("status_1", R.drawable.marker1);
        put("status_2", R.drawable.marker2);
        put("status_3", R.drawable.marker3);
    }});

    // get current location and move camera to it
    AndExMapHelper.animateCamera(AndExMapHelper.getCurrentLocation(),AndExMapHelper.DEFAULT_ZOOM);

    // set info windows adapter
    AndExMapHelper.setInfoWindowAdapter(new GoogleMap.InfoWindowAdapter() {
        @Override
        public View getInfoWindow(Marker marker) {
            return null;
        }

        @Override
        public View getInfoContents(Marker marker) {
            LayoutInflater inflater = (LayoutInflater) MainActivity.this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            View rowView = inflater.inflate(R.layout.item_marker_location, null);
            TextView tvTitle   = rowView.findViewById(R.id.tvMarkerTitle);
            TextView tvSnippet = rowView.findViewById(R.id.tvMarkerSnippet);
            tvTitle.setText(marker.getTitle());
            tvSnippet.setText(marker.getSnippet());
            return rowView;
        }
    });
}


@Override
public void onLocationChanged(Location location) {
    // show current location on map with arbitary title, snippet and icon
    AndExMapHelper.showCurrentLocationOnMap(this,"Title", "Snippet", R.drawable.ic_current_location);
}

Add Marker

AndExMapHelper.addMarker(context,location, title, snippet, status);

Create a location object

AndExMapHelper.locationInstance(latitude,longitude);

Get location of selected marker

AndExMapHelper.getSelectedLocation();

Change Status

AndExMapHelper.changeStatus(context, location, newStatus);

Remove marker

AndExMapHelper.removeMarker(context, location);

Draw circle

AndExMapHelper.drawCircle(centerLocation, radius, strokeWidth, strokeColor, fillColor);
AndExMapHelper.drawCircle(centerLatLng, radius, strokeWidth, strokeColor, fillColor);

Remove circle

AndExMapHelper.removeCircle(context, centerLocation);

Draw Polygon

AndExMapHelper.drawPolygon(strokeWidth, strokeColor, fillColor, LatLng... latLngs);

Filter

// filter with statues. only markers display whose its status be in statues
AndExMapHelper.filter(context, String... statuses); 

// filter with distance. only markers display whose distance to centerLocation be less than maxDistanceToCenterLocation parameter
AndExMapHelper.filter(context, centerLocation, maxDistanceToCenterLocation);

// filter with distance. only markers display whose distance to current Location be less than maxDistanceToCurrentLocation parameter
AndExMapHelper.filter(context, maxDistanceToCurrentLocation);

Refresh the map

AndExMapHelper.refreshMap(context);

Clear the map

AndExMapHelper.clearMap();
