Answer 1

In Activity use something like this where you load your fragment:

FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
transaction.replace(container, fragment);

transaction.addToBackStack(null); // if you want to store transaction        
transaction.commit();
currentFragment = fragment; // currentFragment is global Fragment variable

Use following line where you want to call fragment's method

currentFragment.setItemFromDrawer("sourceTag","destTag");
