1- I don't like listening to music, and (I) also don't like watching Tv.
2- I don't like listening to music, and (I) don't like watching Tv as well.
Is it possible to use 'also, as well' in negative sentences as it mentioned above or must I use 'either' or 'neither' instead of them?
You can use it but it makes for a rather unnatural sentence because it means you end up repeating the "don't like" part. Sentence 1 is OK. Sentence 2 is not.
I don't like listening to music or watching TV.
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
