Keep Fragments Synconized - Fragment Android

Question

I have an Android App using Fragments to create a sliding view. I have 5 "Buttons" represented by FrameLayouts with content in them in Fragment A and Fragment B.

When clicking a Layout it turn green for a few seconds, and the others don't in that space of time:

c05.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                if (Storage.isWaiting)
                    return;

                Storage.isWaiting = true;
                Toast.makeText(getActivity().getApplicationContext(), "Text abc 123", Toast.LENGTH_LONG).show();
                c05.setBackgroundColor(Color.parseColor("#ff408c3a"));

                Handler handler = new Handler();
                handler.postDelayed(new Runnable() {
                    @Override
                    public void run() {
                        c05.setBackgroundColor(Color.parseColor("#393939"));
                        Storage.isWaiting = false;
                    }
                }, 3000);
            }
        });

I now need the to fragments to "syncronize" in a way that when i press button c01 in Fragment A c01 in Fragment B becomes green as well.

Do you have any Ideas how to do that?

From what i can understand you basically want to communicate between two fragments. The basic rule is to communicate via the container activity and if possible by using interfaces.
