Answer 1

To reference your Button within your fragment you want to do it in onCreateView:
public View onCreateView(#NonNull LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_more, container,false);
btn_share = (Button) rootView.findViewById(R.id.btn_share);
btn_share.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View _view) {
a = textview6.getText().toString();
b = textview6.getText().toString();
Intent i = new Intent(android.content.Intent.ACTION_SEND); i.setType("text/plain"); i.putExtra(android.content.Intent.EXTRA_SUBJECT, a); i.putExtra(android.content.Intent.EXTRA_TEXT, b); startActivity(Intent.createChooser(i,"Share using"));
}
});
return rootView;
}
