How to open or launch a Fragment from another Activity?

Question

from the adapter of a RecyclerView which is contained in an Activity, i\'m trying to launch a fragment when an element of the RecyclerView is pressed, this is my code right

Answer 1

You can not start a Fragment using Intents. Intents provide a communication between activities.

If you want to launch a Fragment from other Fragment you have two options.

1- You can replace or add a new fragment.

FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction
                .replace( R.id.content_frame, fragment )
                .addToBackStack( null )
                .commit();

In this case The activity has two fragments.

2- You can launch a new Activity that contains a Fragment.
