在Android中将SearchableSpinner与自定义适配器一起使用

Question

我在Android项目中使用‍‍SearchableSpinner，在SearchableSpinner中使用了两个textview，因此制作了一个自定义适配器。当我单击SearchableSpinner时，数据无法正确显示。

这是我的自定义适配器代码。我在自定义适配器中使用getView和getDropDownview。

private ArrayList<University> universityList;
private Activity context;

public UniversityListAdapterForUploadPage(ArrayList<University> universityList, Activity context){
    super(context,R.layout.university_list_row_for_spinner,universityList);
    this.universityList = universityList;
    this.context = context;
}

@NonNull
@Override
public View getView(int position, @Nullable View convertView, @NonNull ViewGroup parent) {

    LayoutInflater layoutInflater = context.getLayoutInflater();
    View customView = layoutInflater.inflate(R.layout.university_list_row_for_spinner,null,true);

    TextView universityIDText  = customView.findViewById(R.id.universityID_textView_for_spinner);
    TextView universityNameText = customView.findViewById(R.id.university_name_textView_for_spinner);

    University university = universityList.get(position);

    universityIDText.setText(university.getUniversityID()+"");
    universityNameText.setText(university.getUniversityName());

    return customView;
}

@Override
public View getDropDownView(int position, @Nullable View convertView, @NonNull ViewGroup parent) {
    LayoutInflater layoutInflater = context.getLayoutInflater();
    View customView = layoutInflater.inflate(R.layout.university_list_row_for_spinner,null,true);

    TextView universityIDText  = customView.findViewById(R.id.universityID_textView_for_spinner);
    TextView universityNameText = customView.findViewById(R.id.university_name_textView_for_spinner);

    University university = universityList.get(position);

    universityIDText.setText(university.getUniversityID()+"");
    universityNameText.setText(university.getUniversityName());

    return customView;
}

我需要帮助。

Answer 1

universityIDText.setText(university.getUniversityID()+"");
universityNameText.setText(university.getUniversityName());

您没有通过这两个电话传递String。您正在传递一个Java对象ID
