    }
};

You are creating the fragment in the activity right ? Why dont you create an object in the activity and call the setter method in the fragment to pass values between activity and fragment. — jgm, Nov 28 '16 at 09:31
You can use simplier approach to send data between fragments and activities — Anton Kazakov, Nov 28 '16 at 09:32

To send data from activity to fragment simply create a Bundle and put required params in that and set that bundle in fragment.setArguments() when you are attaching or replacing that fragment.

Here is an example:

Bundle bundle = new Bundle();
bundle.putInt("Key", 2);
Fragment frag = new YourFragment();
frag.setArguments(bundle);
--> then add or replace fragment as you want.

Update: in the onCreate () method of your fragment put below code:

Bundle bundle = getArguments (); int i = bundle.getInt ("key");

Still not clear then comment below.
