    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

        View rootView=inflater.inflate(R.layout.activity_choix_formulaire,container,false);

        return rootView;

"Cannot resolve constructor 'Intent(com.appli.cci.ports2a.Recherches.ChoixFormulaire, java.lang.Class<com.appli.cci.ports2a.Recherches.RecherchesJournalier>)'

Answer 1

Intents need to be created with the parent activity or the application context.So You need to use your Fragment's Parent Activity Context

Intent intent = new Intent(getActivity(),MyClass.class);

you need you pass array from first activity like this :-

Bundle bundle=new Bundle();
bundle.putStringArray(key, new String[]{value1, value2});
Intent i=new Intent(context, Class);
i.putExtras(bundle);

you can get array from other activity like this

Bundle bundle=this.getIntent().getExtras();
String[] array=bundle.getStringArray(key);

Answer 2

you are not using context properly check this.

 public void formJ(View v){
            Intent i = new Intent(getActivity(),RechercheJournalier.class);
            startActivity(i);
        }
