How to get the current location of the device and show it on a map fragment in a fragment

Question

I am developing an Android application with google maps. Currently, I can view the map inside my application, but I do not know how to view the current location in the application.

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 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 found out that "setmylocationenabled" can help include in FragmentActivity, but unfortunately I have to use this type as "Fragment". And I use google api v2. Please help with this.

How to use the new embedded smooth access provider as indicated: 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 XML like:

  <?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 can get a blank card if you do not have all the requirements, https://developers.google.com/maps/documentation/android/start

• Get Play services in your project by following this entry https://blog-emildesign.rhcloud.com/?p=435

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

• Add permissions for the 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" /> 

• To test the map application, you need to have a real device, if not, then click on the game services for the emulator via adb, read this post to find out how to install the game services using adb fooobar.com/questions/24838 / ...

• After all the steps above, clear the project, delete the previous .apk from the emulator and run the project.

Answer 2

You can include your location, just add this code to your class

  GoogleMap.setMyLocationEnabled(true); 

Answer 3

Here is the link that explains everything you need

https://developers.google.com/maps/documentation/android/map

To set the location on the map, you need to use the class below

 LatLong objLatLng=new LatLong(lat,longi); yourMapObject.moveCamera(CameraUpdateFactory.newLatLngZoom(objLatLng, 20)); yourMapObject.animateCamera(CameraUpdateFactory.zoomTo(18), 2000, null); 

Hope this helps you.

Answer 4

You must create your v2 map as follows:

 m = (MapView) v.findViewById(R.id.map); GoogleMap mMap = m.getMap(); 

Now you can use mMap.setMyLocationEnabled(true);

Answer 5

 Use LocationListener: GPSTracker objGPSTracker = new GPSTracker(mContext); objGPSTracker.stopUsingGPS(); objGPSTracker.getLocation(); 

This is the class for GPSTracker.

 public class GPSTracker extends Service implements LocationListener { private final Context mContext; // flag for GPS status boolean isGPSEnabled = false; // flag for network status boolean isNetworkEnabled = false; // flag for GPS status boolean canGetLocation = false; // Location location; // location double latitude; // latitude double longitude; // longitude // The minimum distance to change Updates in meters private static final long MIN_DISTANCE_CHANGE_FOR_UPDATES = 50; // 10 meters // The minimum time between updates in milliseconds private static final long MIN_TIME_BW_UPDATES = 1000 * 60 * 1; // 1 minute // Declaring a Location Manager protected LocationManager locationManager; public GPSTracker(Context context) { this.mContext = context; //getLocation(); } public Location getLocation() { try { locationManager = (LocationManager) mContext.getSystemService(LOCATION_SERVICE); // getting GPS status isGPSEnabled = locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER); // getting network status isNetworkEnabled = locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER); if (!isGPSEnabled && !isNetworkEnabled) { // no network provider is enabled } else { this.canGetLocation = true; if (isNetworkEnabled) { locationManager.requestLocationUpdates( LocationManager.NETWORK_PROVIDER, MIN_TIME_BW_UPDATES, MIN_DISTANCE_CHANGE_FOR_UPDATES, this); Log.d("Network", "Network"); if (locationManager != null) { location = locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER); if (location != null) { Constant.mLocation = location; latitude = location.getLatitude(); longitude = location.getLongitude(); } } } // if GPS Enabled get lat/long using GPS Services if (isGPSEnabled) { if (location == null) { locationManager.requestLocationUpdates( LocationManager.GPS_PROVIDER, MIN_TIME_BW_UPDATES, MIN_DISTANCE_CHANGE_FOR_UPDATES, this); Log.d("GPS Enabled", "GPS Enabled"); if (locationManager != null) { location = locationManager .getLastKnownLocation(LocationManager.GPS_PROVIDER); Constant.mLocation = location; if (location != null) { latitude = location.getLatitude(); longitude = location.getLongitude(); } } } } } } catch (Exception e) { e.printStackTrace(); } return location; } /** * Stop using GPS listener Calling this function will stop using GPS in your * app * */ public void stopUsingGPS() { if (locationManager != null) { locationManager.removeUpdates(GPSTracker.this); } } /** * Function to get latitude * */ public double getLatitude() { if (location != null) { latitude = location.getLatitude(); } // return latitude return latitude; } /** * Function to get longitude * */ public double getLongitude() { if (location != null) { longitude = location.getLongitude(); } // return longitude return longitude; } /** * Function to check GPS/wifi enabled * * @return boolean * */ public boolean canGetLocation() { return this.canGetLocation; } /** * Function to show settings alert dialog On pressing Settings button will * lauch Settings Options * */ public void showSettingsAlert() { AlertDialog.Builder alertDialog = new AlertDialog.Builder(mContext); // Setting Dialog Title alertDialog.setTitle("GPS settings"); // Setting Dialog Message alertDialog .setMessage("GPS is not enabled. Do you want to go to settings menu?"); // On pressing Settings button alertDialog.setPositiveButton("Settings", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int which) { Intent intent = new Intent( Settings.ACTION_LOCATION_SOURCE_SETTINGS); mContext.startActivity(intent); } }); // on pressing cancel button alertDialog.setNegativeButton("Cancel", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int which) { dialog.cancel(); } }); // Showing Alert Message alertDialog.show(); } public void onLocationChanged(Location location) { Constant.mLocation = location; } public void onProviderDisabled(String provider) { } public void onProviderEnabled(String provider) { } public void onStatusChanged(String provider, int status, Bundle extras) { } @Override public IBinder onBind(Intent arg0) { return null; } }
