Send data from Activity to Fragment already created

I only have found information about how to create a Fragment sending some data to it, but only in its instantiation with the constructor.

But I want to know if it is possible to send some data (for instance, two Double objects) to a Fragment from an Activity without having to create a new instance of the Fragment.

A Fragment that has been previously created.

Solution

  • Just add a method in Fragment which you want to receive arguments, then invoke the method in Activity.
