Map view everytime for show item details

How to map view for selected item details everytime ? Like , i have a list of item in a view . When user select a item , it will show details in other activity . How i will update my View everytime for different different item selection ?

I’m unclear what you mean. Can you give more details?

Like, i need to search user based on user mobile number . User type a mobile number , i need to search that mobile number . I want to create view every time based on user mobile number .

You just need one view. A view is like an index. Create a view that emits the mobile-number property of every user document, then query that view with the key equal to the number you’re looking for.
