This method is called when the buffer is going to replace the
range
dstart … dend
of
dest
with the new text from the range
start … end
of
source
. Return the CharSequence that you would
like to have placed there instead, including an empty string
if appropriate, or
null
to accept the original
replacement. Be careful to not to reject 0-length replacements,
as this is what happens when you delete text. Also beware that
you should not attempt to make any changes to
dest
from this method; you may only examine it for context.
Note: If
source
is an instance of
Spanned
or
Spannable
, the span objects in the
source
should be
copied into the filtered result (i.e. the non-null return value).
copySpansFrom(Spanned, int, int, Class, Spannable, int)
can be used for convenience.
