我需要解析它并得到lat和long值
我已经像这样分配了它
JSONArray JA=new JSONArray(result);
JSONObject json= null;
结果包含Web服务响应。如何解析它并获得所需的值？
答案 0 :(得分：2)
尝试此代码。您将获得lat和lng值：
if (jsonStr != null) {
try {
JSONObject jsonObj = new JSONObject(jsonStr);
// Getting JSON Array node
results = jsonObj.getJSONArray("result");
// looping through All Contacts
for (int i = 0; i < contacts.length(); i++) {
JSONObject c = contacts.getJSONObject(i);
JSONObject geo = c.getJSONObject("geomatrics");
JSONObject place = geo.getJSONObject("location");
String id = place.getString(lat);
String name = place.getString(lng);
}}}

仅供参考，响应JSON是一个Object，而不是一个Array。
results JSON数组geometry子对象。请不要问代码，因为网上有很多JSON教程，但您可以使用以下方法进行解析：
答案 2 :(得分：1)
JSON中有多个位置，因此您需要ArrayList来存储所有这些位置。
我建议使用ArrayList<HashMap<String,Double>>
假设您将结果作为String对象命名为result：
ArrayList<HashMap<String, Double>> list = new ArrayList<HashMap<String,Double>>();
JSONObject jsonObj= new JSONObject(result);
JSONArray results = jsonObj.getJSONArray("results");
for(int i=0;i<results.length();i++){
JSONObject temp = results.getJSONObject(i).getJSONObject("geometry").getJSONObject("location");
Double lat = temp.getDouble("lat");
Double lng = temp.getDouble("lng");
HashMap map = new HashMap<String, Double>();
map.put("lat",lat);
map.put("lng",lng);
list.add(map);
}
现在您可以使用
来检索任何位置Double lat=list.get(4).get("lat");
Double lng=list.get(4).get("lng");
希望它有所帮助。干杯：）
答案 3 :(得分：0)
像这样
将响应转换为JsonObjectJSONObject jsonObj = new JSONObject(result);// where result is the response you got
获取这样的结果数组
JSONArray results = jsonObj.getJSONArray("results"); // where results is the tag in resposne
现在你有了整个数组的结果 for循环整个东西
for(int i=0;i<results.length();i++)
{
JSONObject location = results.getJSONObject(i).getJSONObject("geometry").getJSONObject("location");;
String lat = location.optString("lat");
String lng = location.optString("lng");
}
如果您需要数组中的lat和long，请将它们添加到数组中。
