Ok nevermind what I just said. I now understand what you are talking
about.
Thank you very much!!! I have been banging my head on this for several
days now and this fixes it!
For other people with this problem this is what I did:
SimpleCursorAdapter List=
new SimpleCursorAdapter(this, R.layout.check_row_cursor,
m_Cursor,
new
String[]{DBStorage.DATABASE_TITLE,
DBStorage.DATABASE_CHECKED,
DBStorage.DATABASE_STUFF},
new int[]{ R.id.IsChecked,
R.id.IsChecked,
R.id.stuff});
List.setViewBinder( new SimpleCursorAdapter.ViewBinder()
{
public boolean setViewValue(View view, Cursor cursor,
int
columnIndex)
{
int nCheckedIndex =
cursor.getColumnIndex(DBStorage.DATABASE_CHECKED);
if(columnIndex == nCheckedIndex )
{
CheckBox cb = (CheckBox) view;
boolean bChecked =
(cursor.getInt(nCheckedIndex ) != 0);
cb.setChecked(bChecked );
return true;
}
return false;
}
});
I really appreciate this!! Thanks Hielko !!!
