在 Android 中使用带有自定义适配器的 SearchableSpinner

Question

我在我的 Android 项目和 SearchableSpinner 中使用 ‍‍SearchableSpinner，我使用了两个 textview，所以我制作了一个自定义适配器。 当我单击 SearchableSpinner 时，数据显示不正确。

这是我的自定义适配器代码。 我在我的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());

您没有通过这两个调用传递String 。 您正在传递一个 java 对象 ID

Answer 2

@Override toString() 在您的模型中将此添加到您的模型类中.. 希望它会有所帮助..

public String toString(){
    return universityName;
}
