尝试搜索数据

Question

我正在尝试为我的应用实现搜索栏，我在empList.setAdapter(adapter)下收到此错误 错误是error: cannot find symbol method setAdapter(ArrayAdapter<String>) 为什么会发生此错误，这就是方法的外观

 public boolean onCreateOptionMenu(Menu menu){
        MenuInflater menuInflater = getMenuInflater();
        menuInflater.inflate(R.menu.menu, menu);

        MenuItem menuItem = menu.findItem(R.id.search);
        SearchView searchView = (SearchView) MenuItemCompat.getActionView(menuItem);

        searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener(){
            @Override
            public boolean onQueryTextSubmit(String query) {
                return false;
            }

            @Override
            public boolean onQueryTextChange(String newText) {
                ArrayList<String> empList = new ArrayList<>();

                for (String emp : list){
                    if (emp.toLowerCase().contains(newText.toLowerCase())){
                        empList.add(emp);
                    }
                }


                ArrayAdapter<String> adapter = new ArrayAdapter<String>(ViewEmployee.this, android.R.layout.simple_list_item_1, empList);
                empList.setAdapter(adapter);

                return true;
            }
        });


        return super.onCreateOptionsMenu(menu);
    }
