Problems With Listview Adapter

I have an app which uses a Listview to display Lectures. The Lectures are colour coded according to their type. I used a custom adapter to control the different colours of each lec

Solution 1:

The problem is that your code in getView() gets its data from the class variable mycursor, but when you call changeCursor, the mycursor variable is not getting updated, so you still see the original list. Rather than using mycursor, you should call getCursor() instead.

Solution 2:

Have you tried calling adapter.notifyDataSetChanged() after you call the changeCursor? That should force your menuList to be updated.

Solution 3:

Instead of using getView, you may want to use newView and bindView methods instead...here's an example from some code I've written.

private static class ViewHolder {
    HistoryRowView rowvw;
}

class ReportHistoryAdapter extends CursorAdapter {
    ViewHolder _holder;

    private static final String INFLATER_SVC = Context.LAYOUT_INFLATER_SERVICE;
    private LayoutInflater _inflater;

    public PostureReportAdapter( Context context, Cursor cursor ) {
        super( context, cursor );
        _inflater = (LayoutInflater) context.getSystemService(INFLATER_SVC);

    }

    @Override
    public View newView(Context context, Cursor cursor, ViewGroup parent) {
        View vw = _inflater.inflate( R.layout.reports_history_view, null );
        _holder = new ViewHolder();
        _holder.rowvw = (HistoryRowView)vw.findViewById( R.id.rhv_history_row_vw );
        vw.setTag( _holder );
        return vw;
    }

    @Override
    public void bindView(View vw, Context context, Cursor cursor) {
        _holder = (ViewHolder)vw.getTag();

        int poor = cursor.getInt( 0 );
        int fair = cursor.getInt( 1 );
        int good = cursor.getInt( 2 );
        int date = cursor.getInt( 3 );

        _holder.rowvw.setData( poor, fair, good, date );
    }
}
