Here I am posting the Json Response:
{
"ResultSet": {
"Result": [{
"Phone": "(650) 473-9999",
"Distance": "2.59",
"MapUrl": "http://maps.yahoo.com/maps_result?q1=441+Emerson+St+Palo+Alto+CAgid1=28734629",
"Categories": {
"Category": [{
"content": "Salad Restaurants",
"id": "96926225"
}, {
"content": "Vegetarian Restaurants",
"id": "96926239"
}, {
"content": "Pizza",
"id": "96926243"
}, {
"content": "Wine",
"id": "96926864"
}, {
"content": "Alcoholic Beverages",
"id": "96929810"
}]
},
Now I just want to parse the data
{
"content": "Salad Restaurants",
"id": "96926225"
}, {
"content": "Vegetarian Restaurants",
"id": "96926239"
}, {
"content": "Pizza",
"id": "96926243"
}, {
"c开发者_如何学Content": "Wine",
"id": "96926864"
}, {
"content": "Alcoholic Beverages",
"id": "96929810"
}
from the Category Tag. Can anybody please help me, I am able to parse from the Result Tag. Here is my code :
private String connect(String url) {
// Create the httpclient
HttpClient httpclient = new DefaultHttpClient();
//Prepare a request Object
HttpGet httpget = new HttpGet(url);
//Response Declaration
HttpResponse response;
//Return String Declaration
String returnString = null;
try {
// Open the webpage.
response = httpclient.execute(httpget);
if (response.getStatusLine().getStatusCode() == 200) {
// Connection was established. Get the content.
HttpEntity entity = response.getEntity();
// If the response does not enclose an entity, there is no need
// to worry about connection release
if (entity != null) {
// A Simple JSON Response Read
InputStream instream = entity.getContent();
// Load the requested page converted to a string into a JSONObject.
JSONObject myAwway = new JSONObject(convertStreamToString(instream));
Log.e(DATA, "myData");
System.out.println("Response : - - " + myAwway);
// Get the query value'
// String phone = myAwway.getString("Phone");
/* String resultset = myAwway.getString("ResultSet");
JSONObject temp = new JSONObject(resultset);
String string = temp.getString("Result");
JSONArray result = new JSONArray(string);
*/
String resultset = myAwway.getString("ResultSet");
JSONObject temp = new JSONObject(resultset);
String string = temp.getString("Category");
JSONArray result = new JSONArray(string);
/* JSONObject temp1 = new JSONObject(string);
String string1 = temp1.getString("Category");
JSONArray result1 = new JSONArray(string1);
*/
//JSONArray result = myAwway.getJSONArray("Result").getString(resultset);
// JSONArray result = myAwway.getJSONArray("Result");
// Build the return string.
returnString = "DataFound: " + result.length();
for (int i = 0; i < result.length(); i++) {
//returnString += "\n\t" + result.getString(i);
returnString += "\n\t" + result.getJSONObject(i).getString("Phone");
returnString += "\n\t" + result.getJSONObject(i).getString("Distance");
returnString += "\n\t" + result.getJSONObject(i).getString("BusinessUrl");
returnString += "\n\t" + result.getJSONObject(i).getString("Rating");
/*for (int j = 0; j < result1.length(); j++)
{
returnString += "\n\t" + result1.getJSONObject(j).getString("Category");
} */
System.out.println("JsonOutPut:---" + result);
}
// Close the stream.
instream.close();
}
} else {
// code here for a response other than 200. A response 200 means the webpage was ok
// Other codes include 404 - not found, 301 - redirect etc...
// Display the response line.
returnString = "Unable to load page - " + response.getStatusLine();
}
} catch (IOException ex) {
// thrown by line 80 - getContent();
// Connection was not established
returnString = "Connection failed; " + ex.getMessage();
} catch (JSONException ex) {
// JSON errors
returnString = "JSON failed; " + ex.getMessage();
}
return returnString;
}
This is the site that ought to help you :-)
