我是android开发新手，在我的应用程序中，我使用google place api从地址中获取lat和long，但是我一直在解析json，因为我不知道如何解析这种json。

我试过的密码。
jsonObject = new JSONObject(response);
if (jsonObject.get("results") instanceof JSONObject) {
} else if (jsonObject.get("results") instanceof JSONArray) {
jsonArray = jsonObject.getJSONArray("results");
for (int j = 0; j < jsonArray.length(); j++) {
jsonObject = jsonArray.getJSONObject(i);
latitude = jsonObject.getJSONObject("location").getDouble("lat");
}
}
} catch (JSONException f) {
Log.e("Json exception", f.getMessage());
}
例外
No value for location
请帮助我解析这个json，谢谢
最佳答案
你忘了几何
jsonArray = jsonObject.getJSONArray("results");
for (int j = 0; j < jsonArray.length(); j++) {
jsonObject = jsonArray.getJSONObject(i);
latitude=jsonObject.getJSONObject("geometry").getJSONObject("location").getDouble("lat");
}
