Question

I am running the software but when i scroll with the listview, its showing ok, but after a while i get this error message:

I am trying to display a cursor to a listview.

My Adapter class:

  private class DBAdapter extends SimpleCursorAdapter {
        private LayoutInflater mInflater;
        private Cursor c;
        private Context context;

My Constructor

        public DBAdapter(Context context, int layout, Cursor c, String[] from, int[] to) {
            super(context, layout, c, from, to);
            this.c = c;
            this.context = context;
            mInflater = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        }

getView Method

        @Override
        public View getView(int position, View convertView, ViewGroup parent) {
            ViewHolder holder = null; 
            if (convertView == null) {
                holder = new ViewHolder();
                convertView = mInflater.inflate(R.layout.match_item, null);
                holder.tvHome = (TextView)convertView.findViewById(R.id.ll_home);
                convertView.setTag(holder);
            } else {
                holder = (ViewHolder)convertView.getTag();
            }
                holder.tvHome.setText(c.getString(3)+"("+c.getString(6)+")");
                c.moveToNext();
                return convertView; 
        }
    }

Simple View Holder

    public static class ViewHolder {
        public TextView tvHome;
    }
}

Adapter init

Cursor cur = dh.getAll();
    startManagingCursor(cur);

    String[] from = new String[] { "home" };
    int[] to = new int[] { R.id.ll_home};

    // Now create an array adapter and set it to display using our row
    DBAdapter matches = new DBAdapter(this,R.layout.match_item, cur, from, to);
    setListAdapter(matches);

Can anyone help me to solve this problem?I’ve searched everywhere but i could not find any solution

Best regards,

you’re supposed to override newView and bindView when implementing your own cursor adapter, not getView. i found this: Trying to override getView in a SimpleCursorAdapter gives NullPointerExceptio
