    arrStudent=filterStudent;
    notifyDataSetChanged();

MainActivity.java

RecyclerViewAdapter.filterdList(filterStudent);

Answer 1

而不是RecyclerViewAdapter，您必须使用RecyclerViewAdapter的对象。

RecyclerViewAdapter recyclerViewAdapter = new RecyclerViewAdapter();
recyclerViewAdapter.filterdList(filterStudent);
