Question

I have an ArrayAdapter with ArrayList filled. Each time I click on any of its item I re-fill the ArrayList and send notifyOnDataSetChange() to the adapter. But for unknown for me reason it goes out of ArrayList bounds in it’s getView() method where it populates its items. I don’t understand why this happens. Can you guys explain the theory of getView() invokation so I understand why this going on. Thanks in advance!

Here it is:

class MAdapter extends ArrayAdapter<String> {
    public MAdapter(Context context, int textViewResourceId, List<String> objects) {
        super(context, textViewResourceId, objects);
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    View v = convertView;
    if (v == null) {
        LayoutInflater vi = (LayoutInflater) getActivity().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        v = vi.inflate(R.layout.file_explorer_row, null);
    } else {

    }

        String txt = itemsList.get(position); // Out of bounds happens here
        if (!txt.equals("")) {
            TextView tt = (TextView) v.findViewById(R.id.file_explorer_tv_filename);
            tt.setText(txt);
        }

    return v;
}

itemsList is declared in Outer Class.

Though i am not getting a clear view of what you are asking..i am assuming that , you are refilling the entire ArrayAdapter again….

So try this………

Use removeView() on ListView before setting the adapter to it…

Eg:

ListView.removeView(); 
ListView.setAdapter(yourAdapter);
