SupportMapFragment XML error

Question

Hy guys,

I am trying to use SupportMapFragment to load the Google Maps API into my application. What happens is i try to use a specific layout, not the simple map taking up the whole screen.

Here is the XML:

<?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"
    android:id="@+id/location_stuff" >

    <RelativeLayout
        android:id="@+id/location_header"
        android:layout_width="match_parent"

            <ImageView
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                android:layout_gravity="center"
                android:layout_weight="1"
                android:contentDescription="@string/hello_world"
                android:paddingLeft="10dp"
                android:paddingRight="10dp"
                android:src="@drawable/input_map_white" />
        </LinearLayout>
    </RelativeLayout>

</LinearLayout>

I have created my specific SupportMapFragment class by extension like this:

import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

import com.example.captoom.R;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.SupportMapFragment;

public class LocationFragment extends SupportMapFragment {

    private GoogleMap map=null;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
        Bundle savedInstanceState) {
        View v = inflater.inflate(R.layout.preview_location, container, false);

        SupportMapFragment fragment = (SupportMapFragment) getFragmentManager().findFragmentById(R.id.mapview);
        setMapp(fragment.getMap());
        return v;
    }

    public GoogleMap getMapp() {
        return map;
    }

    public void setMapp(GoogleMap map) {
        this.map = map;
    }
}

When i try to add the fragment to my current activity i get an XML inflating error.

I try to add the fragment like this:

LocationFragment mMapFragment = new LocationFragment();
FragmentTransaction fragmentTransaction = getSupportFragmentManager().beginTransaction();
fragmentTransaction.add(mMapFragment,null);
fragmentTransaction.commit();

Here is the error log:

Any kind of help highly appreciated.

Thanks!

Answer 1

You can fix this, if you delete all nested fragments in onDestroyView().

 public void onDestroyView() {
        super.onDestroyView(); 
        Fragment fragment = (getFragmentManager().findFragmentById(R.id.map));  
        FragmentTransaction ft = getActivity().getSupportFragmentManager().beginTransaction();
        ft.remove(fragment);
        ft.commit();
}

And inflating them as usual in onCreateView()

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    return inflater.inflate(R.layout.map, container, false);
}
