我有以下代码：

public View onCreateView（LayoutInflater inflater，ViewGroup container，Bundle savedInstanceState）{

ViewGroup view = (ViewGroup) inflater.inflate(R.layout.fragment_left, null);

    // test

    SupportMapFragment fragment = new SupportMapFragment();
    FragmentManager fm = getActivity().getSupportFragmentManager();
    FragmentTransaction ft = fm.beginTransaction();
    ft.replace(R.id.map, fragment).commit();

    GoogleMap googleMap = fragment.getMap();

    if(getCameraPosition() == null) { // first time in app
        setCameraPosition(new CameraPosition(getYourLatLng(), 12, 0 ,0));
    }
    googleMap.moveCamera(CameraUpdateFactory.newCameraPosition(getCameraPosition()));       

    googleMap.addMarker(new MarkerOptions()
    .title("Your Position")
    .snippet("This is where your smartphone is located.")
    .position(getYourLatLng()));

    return view;
}

这是我试图在xml文件中替换的内容：

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

怎么了？无论如何要更新ID？
