Information from one fragment is not sending to another

Question

I have a main Activity which contains two Fragments (Each in it's own activity) as ActionTabListener

Everytime I hit the Calculate button I want the information to append on top of what's already under Display Result activity textbox and not overwrite. I tried SharedPreference, but it only works to setText() but .append() doesn't work.

The TextBox is initialized under the Display Trip as

private EditText showLog;

Should I change it to private ?

How do I transfer information between the two activities without losing them within the duration of the application in the memory?

Answer 1

Try this,

 Practice2 newFragment = new Practice2();

                bundle.putString("id", "Information");
                newFragment.setArguments(bundle);

                android.support.v4.app.FragmentManager fragmentManager = getFragmentManager();
                android.support.v4.app.FragmentTransaction transaction = fragmentManager
                        .beginTransaction();

                transaction.replace(R.id.llhome, newFragment);

                // Commit the transaction
                transaction.commit();

and replace the current version of display result with it's self but with the information and if you want you can attach multiple bundles for each string you want to show.
