When opening my SupportMapFragment (Android maps v2) for a second time (calling setContentView) I get the following error:

this.map = ((SupportMapFragment) activity.getSupportFragmentManager()
.findFragmentById(R.id.hits_map)).getMap();
}
}
I have no idea what this error means. Can someone explain this?
回答1:
Instead of declaring de SupportMapFragment in layout, do it programatically and be sure you use getChildFragmentMananger instead of the classic getFragmentManager() to create the fragment.
mMapFragment = SupportMapFragment.newInstance();
FragmentTransaction fragmentTransaction =
mMapFragment.getChildFragmentManager().beginTransaction();
fragmentTransaction.add(R.id.map_root, mMapFragment);
fragmentTransaction.commit();
Keep this SupportMapFragment mMapFragment as you will need it to retrieve the GoogleMap object:
GoogleMap map = mMapFragment.getMap();
回答2:
Update:
As an alternative solution (which I think is much better) you can use a MapView which is described: here
I ran across a similar problem while working with a tabs implementation. With Google Maps V2, you are stuck with the SupportMapFragment, so using the MapView isn\'t an option. Between juanmeanwhile\'s post and comment #1 found here (https://code.google.com/p/gmaps-api-issues/issues/detail?id=5064#c1), I managed to figure out what I was doing wrong.
So, for anyone else getting the Duplicate id error, make sure you declare the fragment programatically, not in XML. This probably means nesting layouts.
<?xml version=\"1.0\" encoding=\"utf-8\"?>
<RelativeLayout xmlns:android=\"http://schemas.android.com/apk/res/android\"
xmlns:map=\"http://schemas.android.com/apk/res-auto\"
android:layout_width=\"match_parent\"
android:layout_height=\"match_parent\" >
<!-- Lots of fancy layout -->
<RelativeLayout
android:id=\"@+id/map\"
android:layout_width=\"match_parent\"
android:layout_height=\"wrap_content\">
</RelativeLayout>
</RelativeLayout>
Then you need to create your fragment programatically, but it needs to be done carefully with consideration for the Fragments lifecycle (http://developer.android.com/reference/android/app/Fragment.html#getChildFragmentManager()). To ensure everything is created at the right time, your code should look like this (taken from comment #1).
public class MyFragment extends Fragment {
private SupportMapFragment fragment;
private GoogleMap map;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
return inflater.inflate(R.layout.layout_with_map, container, false);
}
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
FragmentManager fm = getChildFragmentManager();
fragment = (SupportMapFragment) fm.findFragmentById(R.id.map);
if (fragment == null) {
fragment = SupportMapFragment.newInstance();
fm.beginTransaction().replace(R.id.map, fragment).commit();
}
}
@Override
public void onResume() {
super.onResume();
if (map == null) {
map = fragment.getMap();
map.addMarker(new MarkerOptions().position(new LatLng(0, 0)));
}
}
}
Hopefully this saves some time.

I\'ve spend a half day resolving this trouble and only found a workaround. Override your onCreate
method in YourFragment
class:
public void onCreate(Bundle savedInstanceState) {
setRetainInstance(true);
super.onCreate(savedInstanceState);
}
And override your onDestroy
method:
@Override
public void onDestroyView() {
super.onDestroyView();
try {
SupportMapFragment fragment = (SupportMapFragment) getActivity()
.getSupportFragmentManager().findFragmentById(
R.id.multi_inns_on_map);
if (fragment != null) getFragmentManager().beginTransaction().remove(fragment).commit();
} catch (IllegalStateException e) {
//handle this situation because you are necessary will get
//an exception here :-(
}
}

I had passed all this day looking for the solution to this problem, reading all the workaroung here, and I found this way to solve the problems. I will post all the code, because this question lacks a complete answer, just some tiny snippet that does match a full scenario and does help anybody.
public class LocationFragment extends Fragment implements View.OnClickListener {
private GoogleMap googleMap;
private static View rootView;
private SupportMapFragment supportMapFragment;
public LocationFragment() {
}
@Override
public void onDestroyView() {
super.onDestroyView();
}
@Override
public void onCreate(Bundle savedInstanceState) {
setRetainInstance(true);
super.onCreate(savedInstanceState);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
if(savedInstanceState == null) {
if (rootView != null) {
ViewGroup parent = (ViewGroup) rootView.getParent();
if (parent != null)
parent.removeView(rootView);
}
try{
if(rootView == null)
{
rootView = inflater.inflate(R.layout.fragment_location, container, false);
}
supportMapFragment = (SupportMapFragment) getFragmentManager().findFragmentById(R.id.map);
LocationUtility locationUtility = LocationUtility.getInstance(context);
GoogleMap googleMap = locationUtility.initilizeMap(supportMapFragment);
//More code
} catch (Exception e)
{
e.printStackTrace();
}
}
return rootView;
}
}
By debugging this, you will notice that it does not matter how the fragment operates, you dont need botter for the onDestroyMethod, etc, since the validation of null, just operates with the current instance of the object.
Enjoy! ;)

I ran into this issue and found in my android logs that my hardware acceleration was not turned on. After I turned it on in my AndroidManifest I was displaying the maps multiple times was no longer an issue. I was using an x86 emulator.

My Xml file looks like this:-
<?xml version=\"1.0\" encoding=\"utf-8\"?>
<fragment xmlns:android=\"http://schemas.android.com/apk/res/android\"

android:name=\"com.google.android.gms.maps.MapFragment\"
android:layout_width=\"match_parent\"
android:layout_height=\"match_parent\" />
Most Important thing to note is that DO Not Mix app.Fragment with v4.Fragments else app will crash badly.
As you can see I have used app.Fragment to attach and remove my MapView Fragment
Hope it will help Somebody
回答7:
I tried various solutions proposed here, and the best one IMHO is the MapView. Anyway, I found another solution that could suit your needs (or maybe not).
I had my SupportMapFragment
inside a ViewPager+FragmentPagerAdapter
with 3 tabs. So I just configured the ViewPager in a way that it never destroys the tab where the SupportMapFragment
is.
viewPager.setOffScreenPageLimit(2);
viewPager.setAdapter(...);
With this call, the ViewPager will always maintain two pages after, and two pages before the current one, so none of my three tabs is never destroyed/recreated.
Problem solved :)
Note that memory consumption will increase

回答10:
I have the same issue and solved by creating google map dynamically. What you have to do is making a class which is extending SupportMapFragment class.
This methods works on gingerbread to lollipop and on nested fragments because it will create the map dynamically so don\'t have to worry about removing the fragment or anything like that.
Step1:
public class DynamicMapFragment extends SupportMapFragment {
public GoogleMap googleMap;
public View mOriginalContentView;
public static int statusGooglePlayService;
@Override
public void onCreate(Bundle arg0) {
super.onCreate(arg0);
}
@Override
public View onCreateView(LayoutInflater mInflater, ViewGroup parent,
Bundle arg2) {
mOriginalContentView = super.onCreateView(mInflater, parent, arg2);
//this is for getting height of the phone screen
DisplayMetrics displaymetrics = new DisplayMetrics();
getActivity().getWindowManager().getDefaultDisplay()
.getMetrics(displaymetrics);
int height = displaymetrics.heightPixels;
//Here you can define the height of the map as you desire
FrameLayout.LayoutParams parentLayout = new FrameLayout.LayoutParams(
FrameLayout.LayoutParams.MATCH_PARENT, height / 3);
mOriginalContentView.setLayoutParams(parentLayout);
return mOriginalContentView;
}
@Override
public View getView() {
return mOriginalContentView;
}
@Override
public void onInflate(Activity arg0, AttributeSet arg1, Bundle arg2) {
super.onInflate(arg0, arg1, arg2);
}
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
googleMap = getMap();
statusGooglePlayService = GooglePlayServicesUtil
.isGooglePlayServicesAvailable(getActivity());
if (statusGooglePlayService == ConnectionResult.SUCCESS) {
if (googleMap != null) {
// do whatever you want to do with map
}
} else {
Dialog dialog = GooglePlayServicesUtil.getErrorDialog(
statusGooglePlayService, getActivity(), -1);
dialog.show();
}
}
}
Then call the above created class from Activity, Fragment like this:
Step2:
//Calling the method from a fragment
private void createMap(View rootView) {
FrameLayout mapLayout = (FrameLayout)rootView.findViewById(R.id.location_map);
FragmentTransaction mTransaction = getActivity()
.getSupportFragmentManager().beginTransaction();
SupportMapFragment mFRaFragment = new DynamicMapFragment();
mTransaction.add(mapLayout.getId(), mFRaFragment);
mTransaction.commit();
try {
MapsInitializer.initialize(activity);
} catch (Exception e) {
e.printStackTrace();
}
}
XML layout for fragment where you have to add Framelayout instead
of a fragment for map
Step3:
<?xml version=\"1.0\" encoding=\"utf-8\"?>
<LinearLayout xmlns:android=\"http://schemas.android.com/apk/res/android\"
android:layout_width=\"match_parent\"
android:layout_height=\"match_parent\"
android:orientation=\"vertical\" >
<FrameLayout
android:id=\"@+id/location_map\"
android:layout_width=\"match_parent\"
android:layout_height=\"250dp\"
android:layout_weight=\"0\" />
<!-- You can add any other view also whatever you want to add
<Button
android:layout_width=\"match_parent\"
android:layout_height=\"\"wrap_content\"\"
android:layout_weight=\"0\" /> -->
</LinearLayout>

just put on onCreateView
