MyFragment.java

public class MyFragment extends Fragment{

    protected MapView map;
    AnnotationView annotation;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.fragment, container,false);
        map = (MapView) rootView.findViewById(R.id.map);
        map.getController().setZoom(10);
        map.getController().setCenter(new GeoPoint(12.918609,77.668912));
        map.setBuiltInZoomControls(true);

        // initialize the annotation to be shown later 
        annotation = new AnnotationView(map);

        //addPolyOverlay();
        // addLineOverlay();

        return rootView;
    }

    @Override
    public void onStart() {
        // TODO Auto-generated method stub
        super.onStart();


        addPoiOverlay();
    }


    // add an itemized overlay to map 
    private void addPoiOverlay() {

        // use a custom POI marker by referencing the bitmap file directly,
        // using the filename as the resource ID 
        Drawable icon = getResources().getDrawable(R.drawable.distance_icon_large);
        final DefaultItemizedOverlay poiOverlay = new DefaultItemizedOverlay(icon);

        // set GeoPoints and title/snippet to be used in the annotation view 
        OverlayItem poi1 = new OverlayItem(new GeoPoint (12.918609,77.668912), "Denver, Colorado", "MapQuest Headquarters");
        poiOverlay.addItem(poi1);
        OverlayItem poi2 = new OverlayItem(new GeoPoint (12.956868,77.701148), "Palo Alto, California", "AOL Offices");
        poiOverlay.addItem(poi2);

        // add a tap listener for the POI overlay 
        poiOverlay.setTapListener(new ItemizedOverlay.OverlayTapListener() {
            @Override
            public void onTap(GeoPoint pt, MapView mapView) {
                // when tapped, show the annotation for the overlayItem 
                int lastTouchedIndex = poiOverlay.getLastFocusedIndex();
                if(lastTouchedIndex>-1){
                    OverlayItem tapped = poiOverlay.getItem(lastTouchedIndex);
                    annotation.showAnnotationView(tapped);
                }
            }
        });



        map.getOverlays().add(poiOverlay);

Answer 1

您可能需要覆盖scrollview中的touchlistener，然后将这些事件转发到mapview（如果适用）。问题是，scrollview正在接管触摸侦听器，而没有正确地将其转发出去。

滚动视图里面的mapview看起来很麻烦......

缩放不在android中的scrollview内的地图中工作
