Here is the exmaple

private Handler handler = new Handler(){

    @Override
    public void handleMessage(Message msg) {
        switch(msg.what){
            case 1:{
                showList();
            }break;
        }
    }

};

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState)
{
    /*
    Your initialization code here
    */

    new Thread(){

        @Override
        public void run() {
            String resp = loadURLData(JSON_URL);

            MainActivity.this.items = new ArrayList<Item>();

            try{
                JSONArray items = new JSONArray(resp);

                for(int i = 0; i < items.length(); i++){
                    JSONObject item = items.getJSONObject(i);

                    String title = item.getString("title");
                    String notice = item.getString("notice");

                    Item it = new Item(title, notice);
                }

                handler.sendEmptyMessage(1);
            }catch(JSONException jSONEx){
            }
        }

    }.start();
}

private void showList(){
    ListAdapter adapter = new MyAdapter(this, items);
    listView.setAdapter(adapter);
}

private static String loadURLData(String msgsUrl){
    try{
        URL url = new URL(msgsUrl); 
        URLConnection conn = url.openConnection();
        InputStreamReader streamReader = new InputStreamReader(conn.getInputStream());

        BufferedReader br = new BufferedReader(streamReader);
        StringBuilder sb = new StringBuilder();
        String line = null;
        while((line = br.readLine()) != null) {
            sb.append(line);sb.append("
");
        }
        br.close();
        String resp = sb.toString();

        return resp;
    }catch(IOException iOEx){
        return "";
    }
}
