无法解析谷歌的地方JSON响应 - org.json.JSONException
问题描述:
我收到来自谷歌API的JSON响应,我试图解析。但我得到org.json.JSONException。无法解析谷歌的地方JSON响应 - org.json.JSONException
这是我的JSON响应。
我使用下面的代码来检索格式的地址。
try {
Log.e("test-ttt", jsonResults.toString());
// Create a JSON object hierarchy from the results
JSONObject jsonObj = new JSONObject(jsonResults.toString());
JSONObject placeDetailsJsonArray = jsonObj.getJSONObject("result");
// Extract the Place descriptions from the results
placeDetails = "NAME: " + placeDetailsJsonArray.getJSONObject("name").toString();
placeDetails += "ADDRESS: " + placeDetailsJsonArray.getJSONObject("formatted_address").toString();
} catch (JSONException e) {
Log.e(TAG, "Cannot process JSON results", e);
}
这是logcat的例外,我得到:
org.json.JSONException: Value South Point School at name of type java.lang.String cannot be converted to JSONObject
at org.json.JSON.typeMismatch(JSON.java:100)
at org.json.JSONObject.getJSONObject(JSONObject.java:578)

placeDetails = "NAME: " + placeDetailsJsonArray.getJSONObject("name").toString();
placeDetails += "ADDRESS: " + placeDetailsJsonArray.getJSONObject("formatted_address").toString();
什么我错在这里做什么?
答
您将“name”和“formatted_address”视为JSONObject而不是普通的键/值对。
试试这个:
JSONObject placeDetailsJsonArray = jsonObj.getJSONObject("result");
String name = placeDetailsJsonArray.getString("name");
答
我不知道什么是jsonResults
,但最有可能做jsonResults.toString()
这里:
JSONObject jsonObj = new JSONObject(jsonResults.toString());
不给有效的JSON字符串。你应该检查你正在处理的是什么(做Log.d("X", jsonResults.toString());
),而不是显示什么远程API产生。
答
名称和的formatted_address是在JSON字符串都,但你正在试图获得它的JSONObject。相反使用类似
placeDetails = "NAME: " + placeDetailsJsonArray.get("name").getAsString();
placeDetails += "ADDRESS: " + placeDetailsJsonArray.get("formatted_address").getAsString();
