我发现来自Android库的Google Places API的Place类错过了Web-Service API中提供的大量数据。
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，类定义与评论或营业时间无关。为什么会这样？是否有可能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？也许有能力将Place对象转换为原始JSON格式以找到一些额外的数据？
答案 0 :(得分：0)
在Android中的地方api只返回一些细节，如地名，纬度，经度等。如果你想要更多细节，你必须调用webservice api。这是URl
https://maps.googleapis.com/maps/api/place/details/json?key={API_KEY}&placeid={PLACE_ID}
此处PLACE_ID将来自Android Places Api中的Place Object

Android中的JSON解析示例
String postalCode="";
String city="";
String state="";
String address="";
JSONObject jsonObj=new JSONObject(rs);
JSONArray addressComponents = jsonObj.getJSONObject("result").getJSONArray("address_components");
for(int i = 0; i < addressComponents.length(); i++) {
JSONArray typesArray = addressComponents.getJSONObject(i).getJSONArray("types");
for (int j = 0; j < typesArray.length(); j++) {
if (typesArray.get(j).toString().equalsIgnoreCase("postal_code")) {
postalCode = addressComponents.getJSONObject(i).getString("long_name");
}else if (typesArray.get(j).toString().equalsIgnoreCase("locality")) {
city = addressComponents.getJSONObject(i).getString("long_name");
}else if (typesArray.get(j).toString().equalsIgnoreCase("administrative_area_level_1")) {
state = addressComponents.getJSONObject(i).getString("long_name");

String types=typesArray.get(j).toString();
if(types.equalsIgnoreCase("street_number")
