DialogFragment上的SupportMapFragment

Question

我需要在Dialog中嵌入一个SupportMapFragment。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，当我调用它时：

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

我明白了：

如何才能在对话框中查看地图？

这个应用程序还有另一个SupportMapFragment正在创造奇迹，所以它与配置没有任何关系。

最后，我最终在常规Dialog中使用了MapView，而不是SupportMapFragment

这是我的代码：

final Historico h = adapter.getItem(arg2 - 1);
if (mv.getParent() != null) {
    ((ViewGroup) mv.getParent()).removeView(mv);
}
final Dialog d = new Dialog(HistorialScreen.this);
d.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);
d.requestWindowFeature(Window.FEATURE_NO_TITLE);
d.setContentView(mv);
mv.getMap().clear();
mv.getMap().moveCamera(CameraUpdateFactory.newLatLngZoom(h.getPosicion(), 17));
final MarkerOptions options = new MarkerOptions();
options.icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_CYAN));
options.position(h.getPosicion());
mv.getMap().addMarker(options);
d.show();

并且它的工作方式与预期的一样。

您可以通过以下方式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>
