Android 带有自定义标记的地图+；查看所有标记

嗨，伙计们，我公开了我的问题，但在我向你们展示我创建的代码之前，我将提供更多细节：

        @Override
    public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState, R.layout.activity_map);

            GoogleMap map = ((SupportMapFragment) getSupportFragmentManager()
                            .findFragmentById(R.id.map)).getMap();

            if (map != null) {
                    // Ciclo un mio ArrayList contenente contenuti con relative Latitudine e Longitudine
                    for (int i = 0; i < Contenuti.size(); i++) {
                            double lat = Double.parseDouble(Contenuti.get(i)
                                            .getLatitude());
                            double lng = Double.parseDouble(Contenuti.get(i)
                                            .getLongitude());

                            LatLng PUNTI = new LatLng(lat, lng);
                            String title = Contenuti.get(i).getName();

                            map.addMarker(new MarkerOptions()
                                            .position(POI_POINT).title(title));
                    }

                    map.moveCamera(CameraUpdateFactory.newLatLngZoom(STARTING_POINT, 5));
                    map.animateCamera(CameraUpdateFactory.zoomTo(15), 2000, null);

            }

    }

我使用外部库universalimageloader来显示图像。它是有效的。。。但这不是我想要的，因为它们是应该产生这种效果的标记

提前感谢您的合作

我等待你的建议

private class CustomInfoWindowAdapter implements InfoWindowAdapter {

            private View view;

            }

            @Override
            public View getInfoContents(Marker marker) {
                    if (MapActivity.this.marker != null
                                    && MapActivity.this.marker.isInfoWindowShown()) {
                            MapActivity.this.marker.hideInfoWindow();
                            MapActivity.this.marker.showInfoWindow();

                    MapActivity.this.marker = marker;

                    String url = null;

                    if (marker.getId() != null && markers != null && markers.size() > 0) {
                            if (markers.get(marker.getId()) != null
                                            && markers.get(marker.getId()) != null) {
                                    url = markers.get(marker.getId());

                                    && !url.equalsIgnoreCase("")) {
                            ImageLoader.getInstance().displayImage(url, image);
                    } else {
                            image.setImageResource(R.drawable.ic_launcher);
                    }

                    return view;
            }

    }

    private void initWidget() {
            txtHeader = (TextView) findViewById(id.txtHeaderMenu);

            if (Commons.categoriesList != null) {
                    txtHeader.setText(Commons.categoriesList.get(Commons.cat_id)
                                    .getName());
            }

    }
