Vanligvis vi bruker adjektiv etter 有点. Og vi bruker 一点+ noen. For eksempel 今天(i dag (er det))有点冷(kaldt). 我喝(jeg drikker)一点水(vann).

the key to different with two term is got to know the morphology of "有点儿" in fact, it comes from "有+ 一点儿". before the " 一' normally can be missed when used with verb or adj. together, so it will appear as " 有点儿“ for example. 我有一点儿饿 = 我有点儿饿。（ i feel a little bit hungry.) 我想喝一点儿水 = 我想喝点儿水 （ i'd like drink a little bit water.) when it comes to " 一点儿”， is just used to talk about the quantity or some level. can be used exculsively. compare the two dialoge and help can make u feel more clear about their difference. - 你会说中文吗？（ can you speak chinese?） - 一点儿。or 会说一点儿。（ i can speak a little bit. ） - 你饿了吗？ （ are you hungry? ) - 有点儿。or 我有点儿饿。 （i feel hungey a little bit)

I think "有点儿" = "is kind of" or "there is a few" For example, "它有点儿奇怪"means"it is kind of weird" "一点儿“ is an adjective or adverb, means "a few, a little bit". You can also say "它有一点儿奇怪", which has the same meaning. "快一点儿" means "hurry up"
