java - Android - 获取附近地点的列表

Question

我需要能够在我的应用程序中获取附近地点的列表。我也希望它位于 NavigationDrawer 内。就像 Google Now 的附近地点卡一样:

虽然我希望将其包装在 NavigationDrawer 中。有办法做到这一点吗？

谢谢。

Google Places API 是一项基于网络的服务，因此您需要将请求发送至:

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

您将返回的结果将采用 JSON 格式，使用 GSON 可以轻松解析该结果。 :

{
   "html_attributions" : [],
   "results" : [
      {
         "geometry" : {
            "location" : {
               "lat" : 37.79593620000001,
               "lng" : -122.40000320
            },
            "viewport" : {
               "northeast" : {

然后，如果您愿意，可以将其传递到抽屉导航的适配器。如果即使在离线模式下您也想在抽屉导航中显示此数据，请将此数据缓存在 txt 文件中，并在启动应用程序时读取它。这还有一个额外的优点，即仅在用户选择时才刷新此数据，从而节省带宽。

如果您希望地点按距离排名，请将 &rankby=distance 添加到您的请求网址。
