How to retrieve current device location & show it on map fragment in a fragment

Issue

I'm developing a android app with google maps. Currently I'm able to view the map inside my app, but I don't know how to view the current location on the app.

Here is my code:

public class MapsFragment extends Fragment{
        MapView m;

        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container, 
                Bundle savedInstanceState) {
            // inflat and return the layout
            View v = inflater.inflate(R.layout.map_near_me, container, false);
            m = (MapView) v.findViewById(R.id.map);
            m.onCreate(savedInstanceState);
            return v;
        }
}

Edited: And the xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <com.google.android.gms.maps.MapView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/map" />

</LinearLayout>

This code works fine and I got to know 'setmylocationenabled' can help to enable in FragmentActivity, but unfortunately I have to use the type as 'Fragment'. And I'm using google api v2. Please someone help with this.

Solution

How about using the newly introduced fused location provider as referenced from: http://developer.android.com/training/location/retrieve-current.html

public static class XYZ extends Fragment
            implements
                GooglePlayServicesClient.ConnectionCallbacks,
                GooglePlayServicesClient.OnConnectionFailedListener,
                LocationListener {
        GoogleMap map;
        LatLng latlng;
        private LocationRequest lr;
        private LocationClient lc;
        MapFragment mapFragment;
        ImageView iv;
        private static View view;

        public XYZ() {
        }

        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container,
                Bundle savedInstanceState) {

            if (view != null) {
                ViewGroup parent = (ViewGroup) view.getParent();
                if (parent != null)
                    parent.removeView(view);
            }

            try {
                view = inflater.inflate(R.layout.XYZ, container,
                        false);

                mapFragment = ((MapFragment) this.getActivity()
                        .getFragmentManager().findFragmentById(R.id.map));
                iv = (ImageView) view.findViewById(R.id.iv);

                map = mapFragment.getMap();
                map.getUiSettings().setAllGesturesEnabled(false);
                map.getUiSettings().setMyLocationButtonEnabled(false);
                map.setMyLocationEnabled(true);
                map.getUiSettings().setZoomControlsEnabled(false);

                MapsInitializer.initialize(this.getActivity());
            } catch (GooglePlayServicesNotAvailableException e) {
                Toast.makeText(getActivity(), "Google Play Services missing !",
                        Toast.LENGTH_LONG).show();
            } catch (InflateException e) {
                Toast.makeText(getActivity(), "Problems inflating the view !",
                        Toast.LENGTH_LONG).show();
            } catch (NullPointerException e) {
                Toast.makeText(getActivity(), "Google Play Services missing !",
                        Toast.LENGTH_LONG).show();
            }

            return view;
        }
        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            lr = LocationRequest.create();
            lr.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
            lc = new LocationClient(this.getActivity().getApplicationContext(),
                    this, this);
            lc.connect();
        }

        @Override
        public void onLocationChanged(Location l2) {
            CameraUpdate cameraUpdate = CameraUpdateFactory.newLatLngZoom(
                    new LatLng(l2.getLatitude(), l2.getLongitude()), 15);
            map.animateCamera(cameraUpdate);
        }

        @Override
        public void onConnectionFailed(ConnectionResult arg0) {

        }

        @Override
        public void onConnected(Bundle connectionHint) {
            lc.requestLocationUpdates(lr, this);

        }

        @Override
        public void onDisconnected() {

        }
    }

With the XML as:

      <?xml version="1.0" encoding="utf-8"?>
      <RelativeLayout
                android:layout_width="match_parent"
                android:layout_height="0dp"
                android:layout_marginBottom="4dp"
                android:layout_weight="1" >

                    <fragment
                        android:id="@+id/map"
                        android:name="com.google.android.gms.maps.MapFragment"
                        android:layout_width="match_parent"
                        android:layout_height="match_parent"
                        />

                    <ImageView
                        android:id="@+id/iv"
                        android:layout_width="match_parent"
                        android:layout_height="match_parent"
                        android:background="@android:color/transparent" />

            </RelativeLayout>

You may get a blank map if you don't have all the requirements, https://developers.google.com/maps/documentation/android/start

1. Get Play services on your project by following this post https://blog-emildesign.rhcloud.com/?p=435

2. Then get an api key: https://blog-emildesign.rhcloud.com/?p=403

3. Add the permissions to you manifest,

      <uses-permission android:name="your.application.package.permission.MAPS_RECEIVE"/>
      <uses-permission android:name="android.permission.INTERNET" />
      <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
      <uses-permission    android:name="com.google.android.providers.gsf.permission.READ_GSERVICES"/>
      <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
      <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
   

4. To test the map application you need to have a real device, if not then push play services to emulator via adb, read this post to learn how to install play services via adb https://stackoverflow.com/a/13869332/826657

5. After all steps above, clean your project, uninstall the previous .apk from emulator, and run the project.
