I have mutli obserables of type Observable I want to put them all in one Obseravble and observe this one only.

CodePudding user response：

If you want each Observable to be done and then going to the next Observable (In Sequence) then you can use:

Obserable.concat(Obseravble<T>, Obserable<T>, Obserable<T>)

If you don't care about their sequence you can use:

Obserable.merge(Obseravble<T>, Obserable<T>, Obserable<T>)

Note: You can observe them both in the normal way.
