Zoom to the current location not working with navigation drawer

Question

I'm developing an Android Application which is consists of a Navigation drawer and a Google Map. I have successfully developed my Navigation Drawer and connect my Map into it. The thing is I need my Map to Zoom to the current location.

Here is the code I used in MapsActivity.java .

 protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_maps);
    setUpMapIfNeeded();

    mMap.setMyLocationEnabled(true); // Identify the current location of the device
    mMap.setOnMyLocationChangeListener(this); // change the place when the device is moving

    Location currentLocation = getMyLocation(); // Calling the getMyLocation method
    if(currentLocation!=null){
        LatLng currentCoordinates = new LatLng(
                currentLocation.getLatitude(),
                currentLocation.getLongitude());
        mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(currentCoordinates, 13.0f));
    }

}

Here I implemented getMyLocation() method.

//Zoom to the current location
private Location getMyLocation() {
    LocationManager lm = (LocationManager)getSystemService(Context.LOCATION_SERVICE); // Get location from GPS if it's available
    Location myLocation = lm.getLastKnownLocation(LocationManager.GPS_PROVIDER);
    // Location wasn't found, check the next most accurate place for the current location
    if (myLocation == null) {
        Criteria criteria = new Criteria();
        criteria.setAccuracy(Criteria.ACCURACY_COARSE);
        // Finds a provider that matches the criteria
        String provider = lm.getBestProvider(criteria, true);
        // Use the provider to get the last known location
        myLocation = lm.getLastKnownLocation(provider);
    }
    return myLocation;
}

Here is How I gave MapsFragment in to NavigatioDrawerActivity.

fragment = new MapFragment();

When I run this alone (Insert intent filter to MapsActivity in Manifest) it works perfect. But, when I'm running the Nvigation Drawer as MainActivity this function is not working. Only the default Map is loading.

What should I do?

-edit-

private void setUpMapIfNeeded() {
        // Do a null check to confirm that we have not already instantiated the map.
        if (mMap == null) {
            // Try to obtain the map from the SupportMapFragment.
            mMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map))
                    .getMap();
            // Check if we were successful in obtaining the map.
            if (mMap != null) {
                setUpMap();
            }
        }
    }

My Maps.xml is like this.

<fragment xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/map" 
tools:context=".MapsActivity"
android:name="com.google.android.gms.maps.SupportMapFragment" />

My whole MapsActivity.java

public class MapsActivity extends FragmentActivity implements GoogleMap.OnMyLocationChangeListener {

    private GoogleMap mMap; // Might be null if Google Play services APK is not available.
    private MapView mapView;

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

        mMap.setMyLocationEnabled(true); // Identify the current location of the device
        mMap.setOnMyLocationChangeListener(this); // change the place when the device is moving


        initializaMap(rootView, savedInstanceState);

    }

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

    private void setUpMapIfNeeded() {
        // Do a null check to confirm that we have not already instantiated the map.
        if (mMap == null) {
            // Try to obtain the map from the SupportMapFragment.
            mMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map))
                    .getMap();
            // Check if we were successful in obtaining the map.
            if (mMap != null) {
                setUpMap();
            }
        }
    }

    private void initializaMap(View rootView, Bundle savedInstanceState){
        MapsInitializer.initialize(MapsActivity.this);
        switch (GooglePlayServicesUtil.isGooglePlayServicesAvailable(MapsActivity.this)) {
            case ConnectionResult.SUCCESS:
                mapView = (MapView) rootView.findViewById(R.id.mapView);
                mapView.onCreate(savedInstanceState);

                if (mapView != null) {
                    mMap = mapView.getMap();
                    mMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
                    UiSettings mUiSettings = mMap.getUiSettings();
                    mMap.setMyLocationEnabled(true);
                    mMap.animateCamera(CameraUpdateFactory.zoomTo(15.0f));
                    mUiSettings.setCompassEnabled(true);
                    mUiSettings.setMyLocationButtonEnabled(false);

                    mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(6.9270786, 79.861243), 13));
                }
                break;

Answer 1

try this ..

   map.animateCamera(CameraUpdateFactory.newLatLngZoom((sydney), 13.0f));

you have not given by in float. so its not working.. try this..

Answer 2

try this

map.moveCamera(CameraUpdateFactory.newLatLngZoom(currentCoordinates, 13));

In XML

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

In JAVA Activity

private void initializaMap(Bundle savedInstanceState){
    MapsInitializer.initialize(MainActivity.this);
    switch (GooglePlayServicesUtil.isGooglePlayServicesAvailable(getActivity())) {
    case ConnectionResult.SUCCESS:
        mapView = (MapView) findViewById(R.id.mapView);
        mapView.onCreate(savedInstanceState);

        if (mapView != null) {
            mMap = mapView.getMap();
            mMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
            UiSettings mUiSettings = mMap.getUiSettings();
            mMap.setMyLocationEnabled(true);
            mMap.animateCamera(CameraUpdateFactory.zoomTo(15.0f));
            mUiSettings.setCompassEnabled(true);    
            mUiSettings.setMyLocationButtonEnabled(false);

            mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(mLatitude, mLongitude), 13));
        }
        break;
    case ConnectionResult.SERVICE_MISSING:
        break;
    case ConnectionResult.SERVICE_VERSION_UPDATE_REQUIRED:
        break;
    default:
    }
}

call like this

initializaMap(savedInstanceState);

Answer 3

it will not work because the navigation drawer takes a fragment and you are initializing :

fragment = new MapFragment();  

so it takes the MapFragment default layout .

you must to change the updateDisplay to takes an activity not a fragment . In another words change the navigation drawer to activities instead of fragments
