我有这段代码并尝试运行，但它给了我“org.json.JSONException：Java.lang.String 类型的值 < 无法转换为 JSONObject”的异常。任何帮助都会得到帮助。
代码：
private class MyTask extends AsyncTask<String, Integer, String> {
@Override
protected void onPostExecute(String result) {
CreateAndAppendListLayout();
super.onPostExecute(result);
}
@Override
protected void onPreExecute() {
// TODO Auto-generated method stub
super.onPreExecute();
}
@Override
protected void onProgressUpdate(Integer... values) {
// TODO Auto-generated method stub
super.onProgressUpdate(values);
}
@Override
protected String doInBackground(String... params) {
String myRespone = null;
String url = params[0];
HttpClient client = new DefaultHttpClient();
HttpGet Get = new HttpGet(url);
try {
HttpResponse response = client.execute(Get);
HttpEntity entity = response.getEntity();
myRespone = EntityUtils.toString(entity);
} catch (ClientProtocolException e) {
e.printStackTrace();
Log.e("My webservice Response", "ClientProtocolException");
} catch (IOException e) {
Log.e("My webservice Response", "IOException");
e.printStackTrace();
}
JSONObject jsonObj;
if (myRespone != null) {
try {
jsonObj = new JSONObject(myRespone);
JSONArray jsonArray = jsonObj.getJSONArray("Results");
for (int i = 0; i <= jsonArray.length() - 1; i++) {
myList.add(jsonArray.getJSONObject(i));
}
} catch (Exception e) {
e.printStackTrace();
}
} else {
// do nothing
}
return null;
}
}
我在服务器上的 JSON：
{
"Results": [
{
"id": "10",
"CID": "60607",
"userName": "Jones",
"userr": "hard work",
"st": "4"
},
{
"id": "8",
"CID": "60807",
"userName": "Aaali",
"userr": "Good Service ",
"st": "5"
},
{
"id": "9",
"CID": "65507",
"userName": "Jan",
"userr": "Happy, Cost effective ",
"st": "5"
}
]
}
