我发现 Google Places API 的 Android 库中的 Place 类遗漏了 Web-Service API 中可用的大量数据。
Android 类： https://developers.google.com/android/reference/com/google/android/gms/location/places/Place
网络服务回复： https://developers.google.com/places/web-service/details?hl=en
例如，课程定义与评论或开放时间无关。为什么会这样？是否可以在不将所有应用程序转换为 Web 服务 API 调用和 json 解析的情况下修复它？也许可以将 Place 对象转换为其原始 JSON 形式以查找一些额外的数据？

Android 中的 Places api 仅返回一些详细信息，例如地名、纬度、经度等。如果您需要更多详细信息，则必须调用 webservice api。这是网址
https://maps.googleapis.com/maps/api/place/details/json?key={API_KEY}&placeid={PLACE_ID}
这里的 PLACE_ID 将从 Android Places Api 中的 Place Object 获取

String postalCode="";
String city="";
String state="";
String address="";
JSONObject jsonObj=new JSONObject(rs);
JSONArray addressComponents = jsonObj.getJSONObject("result").getJSONArray("address_components");
