"I don't like that glass either." is the correct phrase. In English we avoid duplicating negative words. "I do not like that glass neither," has two negative words in it and confuses English speakers. Think of it in mathematical terms. If I multiply two negative numbers the result is a positive (-2 x -2 = +4). Because I want to maintain the negative, "I do not like that glass," I can't use the negative form of either (neither). It makes my listener wonder if I in fact do like that glass. You can say in reply to the statement, "I don't like that glass." "Really? Neither do I." The only negative word is neither here, so your meaning in clearly indicated.
The first one
In English you can not have a double negative.
Examples:
I don't like either of those two glasses. One negative OK
I like neither of those two glasss. One negative OK
I don't like neither of those two glasses. Two negatives NOT OK.
I like neither this one nor that one. One negative OK
Also remember
either - or
and
neither - nor.
The first one: either.
You could say: I like neither this glass, nor the other. Neither is used in comparisons, it goes with nor..
Neither Ian nor I know everything, but either way, we give good advice for free.
Anyway, in straightforward sentences, go for either.
