Passing integer between fragments

Question

I have an application with a couple of fragments. I would like a variable that I can edit from each fragment. I mean my main activity shows the first fragment at start. This first fragment has the following code:

button_1.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            FragmentManager fragmentManager = getFragmentManager ();
            FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction ();

            fragmentTransaction.setCustomAnimations(R.anim.enter_from_right, R.anim.exit_to_left).replace(R.id.content_frame, new Fragment_2());
            fragmentTransaction.commit ();


        }});

So this button opens the second fragment, but before that I would like to add 1 to that integer on button click. Then the second fragment has a similar button that should do the same. How can I do that?

make a global variable in calling activity or you can use preferences — UMESH0492, Feb 20 '16 at 11:31

Fragment fragment= new Fragment_2();
Bundle bdl=new Bundle();
bdl.putInt("a",1);
fragment.setArguments(bdl);

 FragmentManager fragmentManager = getFragmentManager ();
            FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction ();

            fragmentTransaction.setCustomAnimations(R.anim.enter_from_right, R.anim.exit_to_left).replace(R.id.content_frame,fragment);
            fragmentTransaction.commit ();

In your second fragment,

int a=getArguments().getInt("a");
