答案 0 :(得分：0)
将字符串转换为JsonObject
JSONObject jObj = null;
jObj = new JSONObject(json);
System.out.print(jObj.toString());
然后，您可以在JSONObject上使用.get方法来检索像
这样的对象值jObj.get('nameofyourvariable');
P.S。 json应该是string，一个json字符串。
答案 1 :(得分：0)
您的字符串是JSONOBject。
protected void onPostExecute(String result) {
try {
JSONObject jsonObject = new JSONObject(result);
// Log.i("JSON", "Number of surveys in feed: " + jsonArray.length());
JSONArray ja = jsonObject.getJSONArray("customers");
// Toast.makeText(MainActivity.this, jsonArray.toString(), Toast.LENGTH_SHORT).show();
// ---print out the content of the json feed---
for (int i = 0; i < ja.length(); i++) {
JSONObject jb = ja.getJSONObject(i);
String s = jb.getString("id");
Log.i("ID is ",s);
String nam = jb.getString("nam");
Log.i("Nam is",nam);
String add = jb.getString("add");
Log.i("Add is",add);
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
您的doInbackground。将String _response声明为类变量。
protected String doInBackground(String... urls) {
HttpClient client = new DefaultHttpClient();
HttpGet httpGet = new HttpGet(urls[0]);
try {
HttpResponse response = client.execute(httpGet);
StatusLine statusLine = response.getStatusLine();
int statusCode = statusLine.getStatusCode();
if (statusCode == 200) {
HttpEntity entity = response.getEntity();
_response=EntityUtils.toString(entity);
}
}
catch (Exception e) {
e.printStackTrace();
}
return _response;
}
编辑：
{表示json对象节点
[表示json数组节点。
{ // your string is a json object
"customers": [ // json array of customers
{ // json object
"id": "C0000002" // json id is string
我刚试了一下。这就是我得到的。
