need help with android

The essence of the problem is that there is a layout in which the SAX parser runs and pulls these exchange rates from the Internet. when I add it to the ListView the program does not start, but when I output it to the console there is data, please help me find where the error is. (XML sample for ListView created this 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
