Um, sorry, in attempting to simplify the example that I presented to
you I didn't manage a full text search and replace.
The text for #bindView should have read (and does in the running code)
@Override
public void bindView(View view, Context context, Cursor cursor) {
final CheckedTextView checkedText = (CheckedTextView) view;
final MyCursor myCursor = (MyCursor) cursor;
final Long rowId = myCursor.getRowId();
checkedText.setChecked(rowModel.isSelected(rowId));
checkedText.setText(myCursor.getDescription());
checkedText.setTag(rowId);
Log.v(TAG, "rowId=" + rowId + " settingChecked=" +
rowModel.isSelected(rowId));
}
