大家好我在我的应用程序片段中有一张地图,我想打印Infowindows的旅行时间,但它需要几秒钟才能显示,因为该应用程序向Google地图发出HTTP请求并接收时间,所以怎么能你认为我打开更快的infowindows?谢谢。

这是我的代码:

map.setInfoWindowAdapter(new InfoWindowAdapter() {

                    @Override
                    public View getInfoWindow(Marker arg0) {
                        return null;
                    }

                    @Override
                    public View getInfoContents(Marker marker) {

                        /* Distanza a piedi e macchina sulla nuvoletta */

查看您的代码似乎时间仅根据地理位置计算,没有任何外部帮助。通过向国家,城市和邮政编码询问当前位置,可能涉及网络请求。 (不能100%肯定,因为它不清楚GPSTracker类中的内容)因为你目前没有使用这些变量,你应该删除它们,你的infowindow会更快出现。
