У меня есть этот макет активности, которая держит фрагмент в нем:активности с грохотом карты фрагмента
<RelativeLayout 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" >
...
<fragment
android:id="@+id/HomeActivity_container_fragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:layout_below="@+id/HomeActivity_navigation_LinearLayout" />
</RelativeLayout>
А вот активность:
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.home_activity); //crashes here
init();
changeFragment(R.id.HomeActivity_container_fragment, new MapFragment());
}
Вот changeFragment функции:
protected void changeFragment(int fragmentContainer, Fragment newFragment)
{
FragmentTransaction transaction = getFragmentManager().beginTransaction();
transaction.replace(fragmentContainer, newFragment);
transaction.addToBackStack(null);
transaction.commit();
}
и вот макет фрагмента карты:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<fragment
android:id="@+id/MapFragment_map_Fragment"
class="com.google.android.gms.maps.MapFragment"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true" />
</RelativeLayout>
и здесь класс карты фрагмент:
public class MapFragment extends Fragment
{
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
View rootView = inflater.inflate(R.layout.map_fragment, container, false);
return rootView;
}
}
Nore: это не проблема с проверкой карты Google, потому что если я ставлю в моей деятельности фрагмент контейнера карты она работает.
Вот исключение, которое я получаю от LogCat:
