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"

try this ..
map.animateCamera(CameraUpdateFactory.newLatLngZoom((sydney), 13.0f));
you have not given by in float. so its not working.. try this..
try this
map.moveCamera(CameraUpdateFactory.newLatLngZoom(currentCoordinates, 13));

}
call like this
initializaMap(savedInstanceState);
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

I have the following code and, when I press a menu button I would like to reposition the same marker and the camera but I do not have idea how to do it, I've read oficial documentation but I haven't found info. I'm using repositionMarker() method to do it, but Im not sure what to do. Thanks

Calling setLocation on the Marker should work, for changing its location. What seems to be your problem is that you are actually removing the marker right before you set the new location.
I am having trouble laying a fragment on top of my existing activity. What I am attempting to accomplish is as follows: Open app -> mapView is created -> navigation drawer is created -> button on navigation drawer opens new fragment laying on top on mapView (while mapView not being visible).

If I understand correctly, what is happening is that the white spaces of your top most Fragment are not capturing click events. To solve this, you need to make the root ViewGroup of the top most Fragment clickable. If the secondFragmentto be added takes up the whole or most of the screen, it is better to call remove() instead of add() in your FragmentTransaction to avoid this issue completely.
I'm trying to applicate drawernavigation (my first fragment is a map & the others are just some fragments with simple layouts).So it runs fine & I can navigate between my fragments but when I return to the first fragment which is a map I got a crash

I think that the problem is located in onResume & onCreateView methods!!
Hope that you'll help me
thanks.
use this
<fragment
android:id="#+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:clickable="true"
/>
and override method onDestroyView() and Just put this code in onDestroyView()
public void onDestroyView()
{
super.onDestroyView();
Fragment fragment = (getFragmentManager().findFragmentById(R.id.map));
FragmentTransaction ft = getActivity().getSupportFragmentManager().beginTransaction();
ft.remove(fragment);
ft.commit();
}
Try to reuse/recycle your layout.
I am running into "duplicate id" when using a map fragment.
So in onCreateView instead of
final View rootView = inflater.inflate(R.layout.fragment_profile, container, false);
i am using
public class YourFragment extends Fragment {
public YourFragment(){}
...
private static View rootView;
...
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
//View rootView = inflater.inflate(R.layout.fragment_layout, container, false);
if (rootView != null) {
ViewGroup parent = (ViewGroup) rootView.getParent();
if (parent != null)
parent.removeView(rootView);
}
try {
rootView = inflater.inflate(R.layout.fragment_layout, container, false);
} catch (InflateException e) {
/* map is already there, just return view as it is */
}
I think you have to try to retrieve old Fragments instance instead of recreating it each time a drawer item is selected. In your displayView method of LoginScreen Activity, you have to do something like that in the switch:
Fragment fragment = null;
String title = getResources().getString(SOME_FRAGMENT_TITLE);
switch (position) {
case 1:
fragment = (YourFragment) fm.findFragmentByTag(title);
if (fragment == null) fragment = new YourFragment();
break;
}
below is my code which display map of all world i want when application start is show specific city not world map i follow this tutorial http://android-er.blogspot.com/2013/01/google-maps-android-api-v2-example-draw.html every thing work fine but i want when app start first time is display specific city map not all global map i dont want show globap map like this image http://1.bp.blogspot.com/-dwjqTWCdONg/UObUk1syAFI/AAAAAAAAGy8/S43YMKuXZRc/s1600/screen_MapsAPIv2_Polygon.png on app start i want specific city map like newyork for example.

add this code to your onCreate:
#Override
protected void onCreate(Bundle savedInstanceState) {
.
.
.
// define point to center on
LatLng origin = new LatLng(40.67, -73.94);
CameraUpdate panToOrigin = CameraUpdateFactory.newLatLng(origin);
myMap.moveCamera(panToOrigin);
// set zoom level with animation
myMap.animateCamera(CameraUpdateFactory.zoomTo(14), 400, null);
}
After the onClikListener are setted (into onCreate), put this code
LatLng NewYork= new LatLng(40.714623,-74.006605);
CameraPosition camPos = new CameraPosition.Builder().target(NewYork).zoom(14).build();
CameraUpdate cam = CameraUpdateFactory.newCameraPosition(camPos);
myMap.animateCamera(cam);
It will animate your map and move the camera to NY
