Android Google Maps v2 not showing Compass and Location Icon

Question

I am not able to show the compass icon and the my location icon either. I have the code googleMap.getUiSettings.setMyLocationButtonEnabled(true) and googleMap.getUiSettings().setCompassEnabled(true); but it is not showing on the maps.

package com.ctc.weathermap;

import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.MapFragment;
import com.google.android.gms.maps.model.BitmapDescriptorFactory;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.MarkerOptions;

import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.os.Bundle;
import android.provider.Settings;
import android.widget.Toast;

public class WeatherMapActivity extends Activity implements LocationListener {

private GoogleMap googleMap;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.weather_maps_main);

    LocationManager lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE);

    lm.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, this);

    LocationManager service = (LocationManager) getSystemService(LOCATION_SERVICE);

    boolean enabledGPS = service.isProviderEnabled(LocationManager.GPS_PROVIDER);
    boolean enabledWiFi = service.isProviderEnabled(LocationManager.NETWORK_PROVIDER);

    if (!enabledGPS) {
        Toast.makeText(this, "GPS signal not found", Toast.LENGTH_LONG).show();
        Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
        startActivity(intent);
    }
    else if(!enabledWiFi) {
           Toast.makeText(this, "Network signal not found", Toast.LENGTH_LONG).show();
           Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
           startActivity(intent);
    }

    initializeMap();
    googleMap.getUiSettings().setMyLocationButtonEnabled(true);
    googleMap.getUiSettings().setCompassEnabled(true);
}

private void initializeMap() {
    // check if map is created
    if(googleMap == null) {
        googleMap = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap(); // creates the map

        // check if map is created successfully or not
        if (googleMap == null) {
            Toast.makeText(getApplicationContext(),
                    "Map could not be created", Toast.LENGTH_SHORT)
                    .show();
        }
    }
}

@Override
protected void onResume() {
    super.onResume();
    initializeMap();
}

@Override
public void onLocationChanged(Location location) {
    googleMap.clear();
    MarkerOptions marker = new MarkerOptions().position(new LatLng(location.getLatitude(), location.getLongitude()));
    marker.title("Current location");   
    marker.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_CYAN));   
    googleMap.addMarker(marker);
    googleMap.animateCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(location.getLatitude(), location.getLongitude()), 16));
}

@Override
public void onProviderDisabled(String arg0) {
    // TODO Auto-generated method stub

}

@Override
public void onProviderEnabled(String arg0) {
    // TODO Auto-generated method stub

}

@Override
public void onStatusChanged(String arg0, int arg1, Bundle arg2) {
    // TODO Auto-generated method stub

}

}

The rest of the code works such as markers and what not. I have tried putting the code for location and compass in initializeMap() but it still does not show up. I would appreciate any help. Thank you!

Answer 1

You havent enabled the my-location layer.Check this link for more details

So please do

googleMap.setMyLocationEnabled(true);

before

googleMap.getUiSettings().setMyLocationButtonEnabled(true);
googleMap.getUiSettings().setCompassEnabled(true);

This will make your setMyLocationButton come up..

And,the compass icon will appear only if you rotate the map to not align to north .
