Custom ArrayAdapter fails. Whatever I try it asks for a resource ID for a TextView

Question

I'm working on that Problem since 6 hours and just can't fix it, anyone sees the mistake?

The revelant part of my MainActivity Code:

private void showAllListEntries() {

    ArrayAdapter<Schulden> adapter = new schuldenArrayAdapter(this, 0, schuldenList);

    ListView schuldenListView = (ListView) findViewById(R.id.schuldenListView);
    schuldenListView.setAdapter(adapter);
}

My Custom Array Adapter:

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;
    }
}

In my listlayout.xml I just have three TextViews which I'm working with by using the Array Adapter.

The Run feed:

I would be very happy about a solution :D

BTW, Java classes should always start with a capital letter. — Doron Yakovlev Golani, Oct 25 '16 at 15:38
`context.getSystemService(MainActivity.LAYOUT_INFLATER_SERVICE)` why do you referring `MainActivity` here? Or is it just a typo? — fluffyBatman, Oct 25 '16 at 15:48

Try replacing your adapter to extend BaseAdapter instead of ArrayAdapter. You will need to implement a few more basic functions, but you have more control and won't hit the problem you are having.

Update: After having an extra look at your code and the stack trace, I am pretty sure that it is not this adapter that is throwing the exception. Are you using any other adapters? This line means that your adapter is not used (as it is not your getView() which is being called): android.widget.ArrayAdapter.getView(ArrayAdapter.java:369)

Thanks for helping. The problem was that the system gave out the failure even if I deleted the adapter. I completley rewrote it the same way and now it works. – Prince1706z Oct 26 '16 at 08:33

Custom ArrayAdapter fails. Whatever I try it asks for a resource ID for a TextView
