Hey guys please need help. A problem with the switch from an activity to fragment in Android Studio.

What I have tried:

So I have used this code: FragmentManager fm = getSupportFragmentManager();
MainFragment fragment = new MainFragment();
fm.beginTransaction().add(R.id.add_activity,fragment).commit();
But it opens a fragment in the same activity while I want the fragment to be opened separately

That is what Android fragment [^] is for,

Quote:
A fragment must always be embedded in an activity and the fragment's lifecycle is directly affected by the host activity's lifecycle.

Otherwise, you have to create a new Activity.

So, you mean there should be a medium activity between the fragment and that activity from which I want to switch to the fragment?

No. If you want a standalone view, you have to use another Activity. Fragment is out of question. Follow this https://developer.android.com/training/basics/firstapp/starting-activity.html to find out how to start another activity.
