CharSequence
filter(CharSequence source, int start, int end, Spanned dest, int dstart, int dend)
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
. Returns the CharSequence that we want
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.
