获取并在Marker信息窗口中显示JSON数据，提取当前位置的位置类型

Question

我有两个自动完成来寻找我完成的路线。现在我有两个地点的路线。我有起点和终点标记。在那个里，我设置了信息窗口来显示纬度，经度，地区，子地区，管理区域。我已经成功地展示了lat和lan。现在我获取Json数据并显示在该信息窗口中。我已经解析了数据，但不知道如何在信息窗口中显示。建议一些解决方案。。

    googleMap.setInfoWindowAdapter(new GoogleMap.InfoWindowAdapter() {
        // Use default InfoWindow frame
        public View getInfoWindow(Marker arg0) {
            return null;
        }
        // Defines the contents of the InfoWindow
        public View getInfoContents(Marker arg0) {
            // Getting view from the layout file info_window_layout
            View v = getLayoutInflater().inflate(R.layout.info_window, null);
            // Getting the position from the marker
            LatLng latLng = arg0.getPosition();

            // Getting reference to the TextView to set latitude
            TextView tvLat = (TextView) v.findViewById(R.id.tv_lat);
            // Getting reference to the TextView to set longitude

您可以使用https://developers.google.com/maps/documentation/android-api/infowindows

或者http://androidfreakers.blogspot.in/2013/08/display-custom-info-window-with.html达到要求。你需要为它创建自定义布局，并从适配器中设置信息。
