ItemizedOverlay OnTap()未触发

我已经定义了地图叠加层,我可以毫无问题地显示标记。我现在正试图在点击一个时发生一些事情,但事件似乎永远不会发生。我确定我错过了一些明显的东西......

public class MapBlobCollection extends ItemizedOverlay<OverlayItem> {

        @SuppressWarnings("serial")
        public class ItemTappedEvent extends EventObject
        {
            public ItemTappedEvent(int itemIndex) {
                super(itemIndex);
            }
        }

        private ArrayList<OverlayItem> myOverlays ;

        public MapBlobCollection(Drawable defaultMarker) {
            super(boundCenterBottom(defaultMarker));
            myOverlays = new ArrayList<OverlayItem>();
            populate();
        }

        public void addOverlay(OverlayItem overlay){
            myOverlays.add(overlay);
            populate();
        }

        @Override
        protected OverlayItem createItem(int i) {
            return myOverlays.get(i);
        }

        // Removes overlay item i
        public void removeItem(int i){
            myOverlays.remove(i);
            populate();
        }

        // Returns present number of items in list
        @Override
        public int size() {
            return myOverlays.size();
        }


        public void addOverlayItem(OverlayItem overlayItem) {
            myOverlays.add(overlayItem);
            populate();
        }


        public void addOverlayItem(int lat, int lon, String title) {
            try {
                GeoPoint point = new GeoPoint(lat, lon);
                OverlayItem overlayItem = new OverlayItem(point, title, null);
                addOverlayItem(overlayItem);    
            } catch (Exception e) {
                // TODO: handle exception
                e.printStackTrace();
            }
        }

        @Override
        protected boolean onTap(int index) {
            super.onTap(index);
            Log.d("TESTING","Triggering tap event on " + Integer.toString(index));
            EventManager.triggerEvent(this, new ItemTappedEvent(index));
            return true;
        }
}

基本上,不会写入调试日志条目,并且不会触发事件。

另外,我的mapview本身并没有平移(应该没有任何额外的代码吗?),尽管设置了setBuitInZoomControls(true),但这些也没有出现......所以也许mapview本身就是有错?

mapview在布局中定义为:

<com.google.android.maps.MapView
android:id="@+id/indexMapView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:apiKey="@string/mapskey_release"/>

我并没有压倒任何抽奖活动或任何事情......

我相信你需要添加

android:clickable="true"

到你的mapview

尝试将超级功能移到最后:

   @Override
     protected boolean onTap(int index) {
         Log.d("TESTING","Triggering tap event on " + Integer.toString(index));
         EventManager.triggerEvent(this, new ItemTappedEvent(index));
         return super.onTap(index);
     }
