I have a main activity which onclick sends an url to another activity
My JSON URL is http://54.218.73.244:7002/
structure response ::
{
"restaurants": [
{
"restaurantID": 1,
"restaurantNAME": "CopperChimney",
"url": "http://54.218.73.244:7002/CopperChimney"
},
{
"restaurantID": 2,
"restaurantNAME": "Aroy",
"url": "http://54.218.73.244:7002/Aroy"
},
{
"restaurantID": 3,
"restaurantNAME": "MarkBoulevard",
"url": "http://54.218.73.244:7002/MarkBoulevard"
},
{
"restaurantID": 4,
"restaurantNAME": "Indian",
"url": "http://54.218.73.244:7002/Indian"
}
],
"RestaurantTimings": [
{
"_id": 1,
"RestaurantTime": "8pm to 11pm"
},
{
"_id": 2,

{
"_id": 3,
"RestaurantTime": "11pm to 9pm"
},
{
"_id": 4,
"RestaurantTime": "10pm to 5pm"
}
]

How to add condition such that on click of a perticular row i could send a
perticular url parsed from the JSON
MainActivity.java
public class MainActivity extends Activity {
// url to make request

httpclient.getParams().setParameter(CoreProtocolPNames.PROTOCOL_VERSION,
HttpVersion.HTTP_1_1);
HttpGet request = new HttpGet(url);
HttpResponse response = httpclient.execute(request);
HttpEntity resEntity = response.getEntity();
_response =EntityUtils.toString(resEntity);
JSONObject jsonObject = new JSONObject(_response);
JSONArray first_array = jsonObject.getJSONArray("restaurants");
JSONArray second_array =
jsonObject.getJSONArray("RestaurantTimings");
for(int i=0;i<first_array.length();i++)
{
JSONObject c = second_array.getJSONObject(i);
Item item = new Item();
// Storing each json item in variable
int id = c.getInt("_id");
String TIME = c.getString("RestaurantTime");
item.setTime(TIME);
c = first_array.getJSONObject(i);
String NAME=c.getString("restaurantNAME");
item.setName(NAME);
String URL=c.getString("url");
item.setUrl(URL);
yourData.add(item);
}
} catch (JSONException e) {
// TODO Auto-generated catch block

} catch (ClientProtocolException e) {
// TODO Auto-generated catch block

} catch (IOException e) {
// TODO Auto-generated catch block

}
return null;
}
@Override
protected void onPostExecute(Void result) {
// TODO Auto-generated method stub
super.onPostExecute(result);
progressDialog.dismiss();
//TextView timedisplay=(TextView)
findViewById(R.id.RestaurantTimeID);
ListView yourListView = (ListView) findViewById(R.id.listViewID);
ListAdapter customAdapter = new ListAdapter(MainActivity.this,
R.layout.itemlistrow, yourData);
yourListView.setAdapter(customAdapter);
yourListView.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
Intent i = new Intent(MainActivity.this,
RestaurantDesc.class);
i.putExtra("key",
"http://54.218.73.244:7002/CopperChimney");
startActivity(i);
}
});
}
}
}
Item.java
public class Item{
private String Name;
private String Time;
private String Url;
public String getName() {
return Name;
}
public void setName(String name) {
Name = name;
}
public String getTime() {
return Time;
}
public void setTime(String time) {
Time = time;
}
public String getUrl() {
return Url;
}
public void setUrl(String url) {
Url = url;
}
}
[EDIT]
I tried using
i.putExtra("key", yourData.get(position).getUrl());
i can get the successfull data onfirst onclick of listview but on second ,
third ,..... i get below error
