Inti masalahnya adalah adanya tata letak di mana parser SAX berjalan dan mengambil nilai tukar ini dari Internet. ketika saya menambahkannya ke ListView program tidak dimulai, tetapi ketika saya mengeluarkannya ke konsol ada data, tolong bantu saya menemukan di mana kesalahannya. (Contoh XML untuk ListView membuat my_list_items_currensy ini)
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
