Я работаю над этой проблемой с 6 часов и просто не могу ее исправить, кто-нибудь видит ошибку?Пользовательский массив ArrayAdapter не работает. Что бы я ни попробовал, он запрашивает идентификатор ресурса для TextView
revelant часть моего MainActivity Код:
private void showAllListEntries() {
ArrayAdapter<Schulden> adapter = new schuldenArrayAdapter(this, 0, schuldenList);
ListView schuldenListView = (ListView) findViewById(R.id.schuldenListView);
schuldenListView.setAdapter(adapter);
}
Мой заказ массив адаптер:
public class schuldenArrayAdapter extends ArrayAdapter<Schulden> {
Context context;
private ArrayList<Schulden> schuldenList;
public schuldenArrayAdapter(Context context, int resource, ArrayList<Schulden> schuldens) {
super(context, resource, schuldens);
this.context = context;
this.schuldenList = schuldens;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
Schulden schulden = schuldenList.get(position);
LayoutInflater inflater = (LayoutInflater) context.getSystemService(MainActivity.LAYOUT_INFLATER_SERVICE);
View view = inflater.inflate(R.layout.listlayout, null);
TextView betragView = (TextView) view.findViewById(R.id.betragtextview);
TextView nameView = (TextView) view.findViewById(R.id.nametextview);
TextView datumView = (TextView) view.findViewById(R.id.datumtextview);
String completeBetrag = schulden.getBetrag() + "€";
betragView.setText(completeBetrag);
nameView.setText(schulden.getName());
SimpleDateFormat datenbankdatumformat = new SimpleDateFormat("yyyy-MM-dd");
SimpleDateFormat ausgabedatumformat = new SimpleDateFormat("dd.MM.yyyy");
Date datumdatenbankformat = datenbankdatumformat.parse(schulden.getDatum(), null);
String datumausgabedatumformat = ausgabedatumformat.format(datumdatenbankformat);
datumView.setText(datumausgabedatumformat);
return view;
}
}
В моей listlayout.xml я только три TextViews, которые я работаю с, используя Адаптер массива.

Я был бы очень рад о решении: D
BTW, классы Java всегда должны начать с большой буквы. –
'context.getSystemService (MainActivity.LAYOUT_INFLATER_SERVICE)' почему вы ссылаетесь на «MainActivity» здесь? Или это просто опечатка? – fluffyBatman
