How to add functionality in fragment java file to share button I created in home fragment?

Question

I have added a floating share button in home_fragment.xml. But I don't know where to start on how to add functionality to that share button. Please help.

This is the code of fragment java file, I have tried do coding but I failed, I'll be glad if anyone can help.

public class HomeFragment extends Fragment {
    @Nullable
    @Override
    public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        return inflater.inflate(R.layout.fragment_home, null);
    }
}

public class HomeFragment extends Fragment {
            Button share_bt;

    @Nullable
    @Override
    public View onCreateView(@NonNull LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View rootView= inflater.inflate(fragment_home, container, false);

        FloatingActionButton share_bt= rootView.findViewById(R.id.share_bt);
        share_bt.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {

                Intent myIntent = new Intent(Intent.ACTION_SEND);
                myIntent.setType("text/plain");
                String shareBody = "hu" ;
                String shareSub = "mk";
                myIntent.putExtra(Intent.EXTRA_SUBJECT,shareBody);
                myIntent.putExtra(Intent.EXTRA_TEXT,shareSub);
                startActivity(Intent.createChooser(myIntent, "Share Using"));
            }
        });
        return rootView;
    }
}
