Question

What I’m trying to do

---

Hello Guys, I’m creating an App for a friend of mine, i simply show his Channel in my App. I get the Data of the Videos over JSON.

Now I found a Problem. When I filled the data into my ListView over the SimpleListAdapter and try to get it over an OnItemClickListner and retrieve them over lv.getItemAtPosition(position); I get all data which is stored in the specific row. But I only need the Link/Url I saved in that field.

Question

Like you read I got more than one information in my ListView to be exactly there are four Strings (Thumb,Title, Content, Link). But I only need to get the String of the Link, how can I do this, down here you find the Code.

 final ListView lv = getListView();
            lv.setOnItemClickListener(new OnItemClickListener(){
                public void onItemClick(AdapterView<?> parent, View v, int position, long id) {

                   Map<String, String> map = mylist.get(position);
                   String link = map.get("Link");


                }
            });
