Google Maps自定义标记未加载Firebase图片

Question

我正在使用Java开发Android Studio应用。我的应用程序允许用户登录并使用自定义标记在地图上查看自定义标记。当用户点击自定义标记时，他们将进入另一项活动。

我的问题是，通过自定义标记访问此活动时，该应用程序不会加载存储在Firebase中的图像。

关于可能是什么问题的任何建议？谢谢。

map activity that deals with the markers:

mMap.setOnMarkerClickListener
(new GoogleMap.OnMarkerClickListener() {
        @Override
        public boolean onMarkerClick(Marker marker) {
            if (marker.getTitle().equals("Mario's Italian"))
                startActivity(new Intent(MapView.this, 
                ItalianMenu.class));
            if (marker.getTitle().equals("Bamboo Tandoori"))
                startActivity(new Intent(MapView.this, 
                IndianMenu.class));
            if (marker.getTitle().equals("King Chinese 
            Takeaway"))
                startActivity(new Intent(MapView.this, 
                ChineseMenu.class));
            return false;
        }
    });
