我在这里遇到问题。在我的android应用程序中,我有这个地方的位置,所以我相对想得到这个地方所属的类型。所以我找到了解决方案,"types" : [ "restaurant", "food", "establishment" ]
但问题是我不知道如何从这个 JSONObject 中提取每种类型。这是一个类似于我想要的东西的例子。
URL googlePlaces = new URL(
"https://maps.googleapis.com/maps/api/place/autocomplete/json?input=" +URLEncoder.encode(args[0], "UTF-8")+"&sensor=true&key=key");
URLConnection tc = googlePlaces.openConnection();
BufferedReader in = new BufferedReader(new InputStreamReader(
tc.getInputStream()));
String line;
StringBuffer sb = new StringBuffer();
//take Google's legible JSON and turn it into one big string.
while ((line = in.readLine()) != null) {
sb.append(line);
}
JSONObject predictions = new JSONObject(sb.toString());
JSONArray ja = new JSONArray(predictions.getString("predictions"));
for (int i = 0; i < ja.length(); i++) {
JSONObject jo = (JSONObject) ja.get(i);
predictionsArr.add(jo.getString("description"));
}
}
