How is this done? I am not having any problems setting String and
integer data through the SimpleCursorAdapter constructor at onCreate
but I can't figure out how to bind the check state of the checkbox
with this method, it always wants to bind to the text field of the
checkbox.
Here is how I am setting up my SimpleCursorAdapter:
SimpleCursorAdapter tasks =
new SimpleCursorAdapter(this, R.layout.check_row_cursor,
m_Cursor,
new String[]{DBStorage.DATABASE_TITLE,
DBStorage.DATABASE_STUFF},
new int[]{ R.id.IsChecked,
R.id.stuff});
The From[] and To[] fields are similar to a ViewBind are they not? I
guess I don't understand how to bind to the isChecked() method of the
CheckBox.
