I have an error when creating a search and list view for my app

Question

My app is linked to a microsoft server which has tables with employee names that need displayed on the app when searched. I also want whenever a letter is typed in the search bar for names to appear that start with that typed letter, I am very close to this but im getting one error that is telling me to create a constructor in two different lines where it says getApplicationContext.

private void initSearchWidgets() {
    SearchView searchView = (SearchView) findViewById(R.id.searchView);

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

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

            MyAppAdapter adapter = new MyAppAdapter(getApplicationContext(), 0, filteredNames);
            listView.setAdapter(adapter);

            return false;
        }
    });
}

private void setUpList() {
    listView = (ListView) findViewById(R.id.searchView);

    MyAppAdapter adapter;
    adapter = new MyAppAdapter(getApplicationContext(), 0, itemsArrayList);
    listView.setAdapter(adapter);
}
