Question

我需要能够在我的应用中获取附近地点的列表。我希望它也在NavigationDrawer中。就像Google Now的邻近地方卡一样：

Google Now card

虽然我希望将它包装在NavigationDrawer中。有什么办法吗？

感谢。

Google Places API是一种基于网络的服务，因此您需要向

发送请求

https://maps.googleapis.com/maps/api/place/search/json
  ?location=COORDINATES_IN_LAT_LONG
  &radius=DISTANCE_IN_METERS
  &key=YOUR_API_KEY

您将获得的结果将是JSON，使用GSON非常容易解析：

{
   "html_attributions" : [],
   "results" : [
      {
         "geometry" : {
            "location" : {

               "lng" : -122.40000320
            },
            "viewport" : {
               "northeast" : {

如果您愿意，可以将其传递给导航栏的适配器。如果您想在离线模式下在导航栏中显示此数据，请将此数据缓存在txt文件中，并在启动应用程序时将其读取。这还具有通过仅在用户选择时刷新该数据来节省带宽的附加优点。

如果您想要按距离排名的地点，请将&rankby=distance添加到您的请求网址。
