How to get selected item of ListView when data comes from the sever in JSON format

The loop for filling data:

while (count<jsonArray.length())
{
    JSONObject jo=jsonArray.getJSONObject(count);
    my_number=(jo.getString("PhoneNumber"));

    steal_number=" My Steal EMG Number is :"+jo.getString("Steal_emg_number");
    fire_number=" My Fire Emg Number is :"+jo.getString("Fire_emg_number");
    child_number=" My Chiledren EMG Number is :"+jo.getString("Children_emg_number");
    trust_con1=" My Trust  Number 1 is :"+jo.getString("trust_nuber1");
    trust_con2=" My Trust Number 2 is :"+jo.getString("trust_nuber2");

    UserInformations userInformations = new UserInformations(my_number, steal_number, fire_number, child_number, trust_con1, trust_con2);
        information_adapter.add(userInformations);
        count++;
    }
}
catch (JSONException e) {
    e.printStackTrace();
}

listView = (ListView) findViewById(R.id.list_view_contacts);

This toast does not return the select item , how can I get the value form the object?

listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        String item = parent.getItemAtPosition(position).toString();     
        Toast.makeText(Steal_Mode.this,item,Toast.LENGTH_LONG).show();
    }
});

Result :
