Specifies a comma-delimited list of primary fields for the cursor or CursorAdapter object. When working with this property for regular cursors, use the CURSORSETPROP( ) and CURSORGETPROP( ) functions. Read/write.
Setting KeyFieldList for CursorAdapter objects overrides the property setting of a cursor when attached to a CursorAdapter object. That is, changing the settings on the cursor using CURSORSETPROP( ) has no effect.
