In an adverbial phrase it is introduced by "from".
It is very difficult to work with people who have a different point of view. NGOs tend to look at things from a different point of view from private firms. (Note that the second "from" here goes with "different"; American English would say "than".) Once you look at it from John's point of view, you will understand his action. From an architect's point of view, this house has not been designed for a tropical climate.
Someone's "view" is their opinion about a particular topic. It is followed by the prepositions "on" or "about".
In my view, Mary should never wear green. People can be friends even though they have different views on politics or religion. (One has one view; another has another.)
You will often see "views" in the plural meaning a coherent philosophy on a subject.
My husband is very supportive of my views on a healthy diet.
"Opinion" can also be used in this context.
I'm sorry, I can't give my views/opinion on this: I haven't thought about it properly yet. What is your opinion/are your views about the case?
"In my opinion", "in their view" etc is often used to imply or admit that what is thought may not be strictly true. No plural here!
In Nancy's view, animals were born to suffer. (I disagree with her.) In my opinion, the above explanation should be enough to clear up any confusion. (The police may think otherwise.)
