Activity向fragment传值

fragment中：

public static TypeFragment newInstance(String Type){    Bundle bundle=new Bundle();    bundle.putSerializable("id",  Type);    TypeFragment fragment=new TypeFragment();    fragment.setArguments(bundle);    return fragment;}

    @Override    public void onCreate(@Nullable Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        Bundle bundle = this.getArguments();        if(bundle != null){            type = bundle.getString("id");        }    }

Activity：

fram1=new TypeFragment().newInstance(id);                fragmentlist.add(fram1);
