DialogFragment上的SupportMapFragment

Question

我需要嵌入SupportMapFragment一个Dialog.这是我能想到的最好的:

public class SupportMapFragmentDialog extends DialogFragment {

    private final SupportMapFragment fragment;

    public SupportMapFragmentDialog() {
        fragment = new SupportMapFragment();
        setTargetFragment(fragment, 1);
    }

    @Override
    public View onCreateView(final LayoutInflater inflater,
            final ViewGroup container, final Bundle savedInstanceState) {
        return fragment.onCreateView(inflater, container, savedInstanceState);
    }

    public SupportMapFragment getFragment() {
        return fragment;
    }

}

但是,当我这样称呼时:

final SupportMapFragmentDialog dialog = new SupportMapFragmentDialog();
dialog.show(getSupportFragmentManager(), "Historico");

我明白了:

如何在Dialog上查看地图？

该应用程序有另一个SupportMapFragment工作奇迹,所以它与配置没有任何关系.

您可以在对话框中显示地图片段

public class DialogMapFragment extends DialogFragment {

    private SupportMapFragment fragment;

    public DialogMapFragment() {
        fragment = new SupportMapFragment();
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.mapdialog, container, false);
        getDialog().setTitle("");
        FragmentTransaction transaction = getChildFragmentManager().beginTransaction();
        transaction.add(R.id.mapView, fragment).commit();

        return view;
    }



    public SupportMapFragment getFragment() {
        return fragment;
    }
}

R.layout.mapdialog:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:padding="0dp" >

    <FrameLayout
        android:id="@+id/mapView"
        android:layout_width="match_parent"
        android:layout_height="match_parent" >
    </FrameLayout>

</RelativeLayout>
