سؤال
I need your help... I work on it until 3 days. My app is working with fragments. One of these fragments has to display a map from the Google Maps V2 api for Android.
Currently, I'm using a MapFragment, but no surprise, a fragment in a fragment is not a good idea, but it works, the map is displaying, i can edit it but when I switch of main fragment and return on it.
Caused by: java.lang.IllegalArgumentException: Binary XML file line #59: Duplicate id 0x7f070041, tag null, or parent id 0x7f070040 with another fragment for com.google.android.gms.maps.MapFragment
at android.app.Activity.onCreateView(Activity.java:4252)
at android.view.LayoutInflater.createViewFromTag(LayoutInflater.java:673)
This is the cause when I go on another fragment and return to the one which contains the map. I'm searching until 3 days to fix this but no great results.
To resume for you, I've an Activity which calls a fragment which contains a MapFragment in the layout file. If you need more, just ask :)
Thanks
Edit : Here is the code to change Fragment in the main Activity

Use MapView instead of MapFragment in your Fragment's layout. Remember to call MapView's lifecycle methods:
as described here.
Btw. you shouldn't be using MapFragment, only SupportMapFragment and support library.
Edit:
If you switch to support library, you can use code from comment #1 here: http://code.google.com/p/gmaps-api-issues/issues/detail?id=5064#c1

Use SupportMapFragment to overcome this error:
In fragment layout
<fragment
android:id="@+id/googleMap"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent" />
In Your Fragment onCreateView
SupportMapFragment mapFragment = (SupportMapFragment) getChildFragmentManager().findFragmentById(R.id.googleMap);
if (mapFragment != null) {
mapFragment.getMapAsync(this);
}
Since your layout is in the Fragment's layout, therefore the SupportMapFragment is the child layout of your fragment. Hence use getChildFragmentManager() which is Fragment's FragmentManager
To display MapFragment inside the fragment(NestedFragment): At this point I believe you have
where.xml
<LinearLayout
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"
android:gravity="center"
android:orientation="vertical" >
<FrameLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1.03"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:id="@+id/mapwhere" />
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
</LinearLayout>
class:
public class WhereFragment extends SupportMapFragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
super.onCreateView(inflater, container, savedInstanceState);
View root = inflater.inflate(R.layout.where, null, false);
initilizeMap();
return root;
}
private void initilizeMap()
{
mSupportMapFragment = (SupportMapFragment) getFragmentManager().findFragmentById(R.id.mapwhere);
if (mSupportMapFragment == null) {
FragmentManager fragmentManager = getFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
mSupportMapFragment = SupportMapFragment.newInstance();
fragmentTransaction.replace(R.id.mapwhere, mSupportMapFragment).commit();
}
if (mSupportMapFragment != null)
{
googleMap = mSupportMapFragment.getMap();
if (googleMap != null)
googleMap.setOnMapClickListener(new OnMapClickListener()
{
@Override
public void onMapClick(LatLng point)
{
//TODO: your onclick stuffs
}
});
}
}
}
Documentation:
Nested Fragments You can now embed fragments inside fragments. This is useful for a variety of situations in which you want to place dynamic and re-usable UI components into a UI component that is itself dynamic and re-usable. For example, if you use ViewPager to create fragments that swipe left and right and consume a majority of the screen space, you can now insert fragments into each fragment page.
To nest a fragment, simply call getChildFragmentManager() on the Fragment in which you want to add a fragment. This returns a FragmentManager that you can use like you normally do from the top-level activity to create fragment transactions. For example, here’s some code that adds a fragment from within an existing Fragment class:
Fragment videoFragment = new VideoPlayerFragment(); FragmentTransaction transaction = getChildFragmentManager().beginTransaction(); transaction.add(R.id.video_fragment, videoFragment).commit(); From within a nested fragment, you can get a reference to the parent fragment by calling getParentFragment().
The Android Support Library also now supports nested fragments, so you can implement nested fragment designs on Android 1.6 and higher.
Note: You cannot inflate a layout into a fragment when that layout includes a . Nested fragments are only supported when added to a fragment dynamically.

In your layout file
<fragment
android:id="@+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
In your fragment onCreate(), reference the map fragment in your fragment layout file using childFragmentManager
// Obtain the SupportMapFragment and get notified when the map is ready to be used.
val mapFragment: SupportMapFragment = childFragmentManager.findFragmentById(R.id.map) as SupportMapFragment
// Set callback on the fragment
mapFragment.getMapAsync(this)

And result looks like this :-
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
You can try adding the MapFragment inside of a FragmentContainerView from androidx Fragment package:
implementation "androidx.fragment:fragment:$1.2.4" <fragment
android:layout_width="match_parent"
android:layout_height="match_parent"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:id="@+id/location_map"
android:layout_above="@id/atmLocation_recyclerView"
/>
View root= inflater.inflate(R.layout.fragment_a_t_m_locations, container, false);
SupportMapFragment mapFragment = (SupportMapFragment) getChildFragmentManager().findFragmentById(R.id.location_map);
mapFragment.getMapAsync(googleMap -> {
mMap=googleMap;
if(mMap!=null){
mMap.setMapType(GoogleMap.MAP_TYPE_HYBRID);
}
});
