java.lang.String不能铸造

当我单击自动完成建议的项目时，我正在尝试获取firebase数据库值。下面的代码是我尝试实施它的方式。但是，我似乎在此行上遇到了java.lang.String cannot be cast to SearchInformation错误：

sInfo = (SearchInformation) adapterView.getAdapter().getItem(i);

我遵循此示例的第一个答案。

注意：我不知道这是否是使用AutoComplete从Firebase数据库中检索信息的正确方法，但是要找出答案，我需要先解决此信息。

代码：

public class Hot extends Fragment {
    private SearchInformation sInfo;
    private DatabaseReference database;

    public Hot() {
        // Required empty public constructor
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.fragment_hot, container, false);
        database = FirebaseDatabase.getInstance().getReference();
        final ArrayAdapter<String> autoComplete = new ArrayAdapter<>(getContext(), android.R.layout.simple_list_item_1);
        database.child("AutoCompleteOptions").addValueEventListener(new ValueEventListener() {
            @Override
            public void onDataChange(DataSnapshot dataSnapshot) {
                for (DataSnapshot suggestionSnapshot : dataSnapshot.getChildren()){
                    sInfo = suggestionSnapshot.getValue(SearchInformation.class);
                    autoComplete.add(sInfo.getEatery_name());
                }
            }
            @Override
            public void onCancelled(DatabaseError databaseError) {
            }
        });
        AutoCompleteTextView ACTV= rootView.findViewById(R.id.actv);
        ACTV.setAdapter(autoComplete);
        ACTV.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
                sInfo = (SearchInformation) adapterView.getAdapter().getItem(i); // ** ERROR HERE **
                String anID = sInfo.getEatery_id(); 
                Log.i("ID is", anID);
            }
        });
        return rootView;
    }
}

数据模型：

public class SearchInformation {
    private String eatery_name;
    private String eatery_id;
    public SearchInformation() {
    }
    public SearchInformation(String eatery_name, String eatery_id) {
        this.eatery_name = eatery_name;
        this.eatery_id = eatery_id;
    }
    public String getEatery_name() {
        return eatery_name;
    }
    public void setEatery_name(String eatery_name) {
        this.eatery_name = eatery_name;
    }
    public String getEatery_id() {
        return eatery_id;
    }
    public void setEatery_id(String eatery_id) {
        this.eatery_id = eatery_id;
    }
}
