Parent Fragment---->(Contains)View Pager------>(Contains)Child Fragment. Child Fragment wants to use Parent Fragment multiple views. Please suggest any solution regarding the same.

Thanks in advance.

Answer 1

in your child fragment use:

ParentFragment frag = ((ParentFragment)this.getParentFragment());

and in your parent fragment you can store the references of your required views and use getter setter to access them, another solution is creating a listener interface. follow below link to find out how to implement:

Answer 2

Inside Parent Fragment

     ViewPagerAdapter adapter = new ViewPagerAdapter(getChildFragmentManager())

make sure it is getChildFragmentManager()

and inside the child fragment, to access anything from parent fragment

     ((ParentFragment)this.getParentFragment()).any_thing_inside_parent_fragment;

Answer 3

You can use the below code.

        FloatingActionButton fab =  getParentFragment().getView().findViewById(R.id.menu_item);
