kailangan ng tulong sa android

Ang kakanyahan ng problema ay mayroong isang layout kung saan ang SAX parser ay tumatakbo at kumukuha ng mga exchange rate na ito mula sa Internet. kapag idinagdag ko ito sa ListView ang programa ay hindi nagsisimula, ngunit kapag na-output ko ito sa console mayroong data, mangyaring tulungan akong mahanap kung saan ang error. (Ginawa ng XML sample para sa ListView itong my_list_items_currensy)

 public class ShowAllActivity extends AppCompatActivity { private ArrayList
  finalList; protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.list_layout); SAXParserFactory saxParserFactory = SAXParserFactory.newInstance(); try { URL url = new URL("http://resources.finance.ua/ua/public/currency-cash.xml"); InputStream stream = url.openStream(); SAXParser saxParser = saxParserFactory.newSAXParser(); // creating a SAX parser Handler handler = new Handler(); saxParser.parse(stream,handler); // here we parse our resource finalList = handler.getListOfAllCurrencies(); } catch (ParserConfigurationException e) { e.printStackTrace(); } catch (SAXException e) { e.printStackTrace(); } catch (MalformedURLException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } adapterList(); } public void adapterList(){ ArrayAdapter
  
   arrayAdapter = new ListOfAllCurrency(); ListView listView=(ListView)findViewById(R.id.c_list); listView.setAdapter(arrayAdapter); } public class ListOfAllCurrency extends ArrayAdapter
   
    { public ListOfAllCurrency() { super(ShowAllActivity.this,R.layout.my_list_items_currensy,finalList); } @Override public View getView(int position, View convertView, ViewGroup parent) { View view = convertView; if( view==null){ view = getLayoutInflater().inflate(R.layout.my_list_items_currensy,parent,false); } TextView bankName = (TextView)view.findViewById(R.id.bankName); TextView currency = (TextView)view.findViewById(R.id.currency); TextView bay = (TextView)view.findViewById(R.id.bay); TextView sell = (TextView)view.findViewById(R.id.sell); bankName.setText(finalList.get(position).getBankName()); StringBuilder itemsString = new StringBuilder(); int lengthListOfCurrency = finalList.get(position).getList().size(); for(int i=0;i
