[android help] JSONArray in a ListView with Android

no. runOnUiThread() is necessary because you want to call setListAdapter.

again. - move these two lines

ListAdapter adapter = new SimpleAdapter(Utenti.this, mylist , R.layout.utentii,new String[] { "name" },new int[] { 1});
setListAdapter(adapter);

right after the for(){} loop in the onClick() method.

if you are sure that your mylist list is populated with data in your json call.

basically something like this as a sample:

replace your xml file contents with the following:

    android:id="@android:id/list"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" /> 

then the onCreate():

  @Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

   setContentView(R.layout. utentii);    
    StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();

      StrictMode.setThreadPolicy(policy);
      lv = getListView();
      lv.setTextFilterEnabled(true);

 populateListView(); ///populate list first time  


 //then onClick() event
lv.setOnItemClickListener(new OnItemClickListener() {
    public void onItemClick(AdapterView parent, View view, int position, long id) {

                  populateListView();    
             }
        });

}

  private void populateListView(){

    Thread t = new Thread(new Runnable (){

        public void run() {
            //Looper.prepare();
            JSONObject json =conn("ketut.php");

            try {
                //Get the element that holds the earthquakes ( JSONArray )
                JSONArray  ute = json.getJSONArray("success");
               final List> mylist = 
                       new ArrayList>();

                   for(int i=0;i < ute.length();i++){

                    JSONObject e = ute.getJSONObject(i);
                     System.out.println(e.getString("user"));

                    mylist.put("name",e.getString("user"));
                }

                runOnUiThread(new Runnable() {


                   public void run() {

                    ListAdapter adapter = new SimpleAdapter(Utenti.this, mylist , R.layout.utentii,new String[] { "name" },new int[] { 1});
                    Utenti.this.setListAdapter(adapter);
                    }

                });

            } catch (JSONException e) {
                System.out.println("4");
                e.printStackTrace();
            }

        }
    });
            t.start();

}

hope this helps abit.
