public CharSequence filter(CharSequence source, int start, int end, Editable 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. 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.
