I have two tabbed activity,I need a program to execute a code snippet whenever a button is clicked on another tab, but this excerpt cannot be Static! How do I do it? Here is the code that has to be executed when the button is clicked on the other tab:
caldroidFragment = new CaldroidFragment();
cyan = new ColorDrawable(Caldroid_fragment.this.getResources().getColor(R.color.Cyan));
white = new ColorDrawable(Caldroid_fragment.this.getResources().getColor(R.color.white));
addToCalendar();
Bundle args = new Bundle();
args.putInt(CaldroidFragment.START_DAY_OF_WEEK, CaldroidFragment.MONDAY);
caldroidFragment.setArguments(args);
java.util.Calendar cal = Calendar.getInstance();
args.putInt(CaldroidFragment.MONTH, cal.get(Calendar.MONTH) + 1);
args.putInt(CaldroidFragment.YEAR, cal.get(Calendar.YEAR));
caldroidFragment.setArguments(args);
caldroidFragment.setCaldroidListener(listener);
FragmentTransaction t = getChildFragmentManager().beginTransaction();
t.replace(R.id.caldroidCal, caldroidFragment);
t.commit();
Parent activity :

Body of tabs 1 and 2 , now , this method is executable in tab 2 , at the click of a tab 1 button:

The method I want to be executable by clicking the add_test button.
There is too much information to provide an answer, but one of the possible methodologies will be to keep a reference to both tab Activity in the parent so that tab Activity A can call a parent Activity method whose code calls the Activity B tab method that performs the code you mention. This is however very inefficient, and should consider tabbed Fragments and learning the Pattern Modelviewpresenter. https://antonioleiva.com/mvp-android/ If you want a response, you must include the activitiys Skeleton and tabbed Activity Adapter.

Have you ever thought of creating a
Base Fragment? She will extend theFragmentand in it you place the functions that you want to execute. As your Tab Fragments will extend from it, it will be visible to both.– LMaker
But this is just a very superficial idea, I think the ideal is to use MVP

I believe that an Eventbus with Subscribe in another Eventbus can solve the problem.
