java - AutoCompleteTextView - 选择名称时获取 Id

Question

我从 api 获取值(我存储在模型中的带有 Id 的名称列表)- 如何将此名称设置为自动完成并在下拉选择中同时获取名称和 Id。这将在自动完成中设置名称并在 onItemClick 处获取名称，但如何获取 ID？

模型类

public class MeetingContactModel implements Serializable {

        private String id;
        private String text;

        public String getId() {
            return id;
        }

        public void setId(String id) {
            this.id = id;
        }

        public String getText() {
            return text;
        }

        public void setText(String text) {
            this.text = text;
        }
}

MyActivity 类创建时:调用自动完成适配器

setMeetingContactAuto(autoContact, contactList);

autoContact.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                strContact =(String) parent.getItemAtPosition(position);
//                strContactCode = code.get(position);
            }
        });

private void setMeetingContactAuto(AutoCompleteTextView autoContact, final ArrayList<MeetingContactModel> xcontactList) {

        List<String> names = new AbstractList<String>() {
            @Override
            public int size() { return xcontactList.size(); }

            @Override
            public String get(int i) {
                code.clear();
                code.add(xcontactList.get(i).getText());
                return xcontactList.get(i).getText();
            }
        };
        autoContact.setThreshold(1);
        autoContact.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, names));
    }

无法获取 ID - 请让我知道以获取它

Answer 1

在模型类中实现 toString() 方法

 public class MeetingContactModel implements Serializable {

    private String id;
    private String text;

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public String getText() {
        return text;
    }

    public void setText(String text) {
        this.text = text;
    }

    @Override
    public String toString() {
        return text;
    }

}


 // Fetch your selected model
 autoContact.setAdapter(new ArrayAdapter<>(requireContext(),  R.layout.spinner_item_ranking, contactList));
 autoContact.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
             MeetingContactModel m=(MeetingContactModel) parent.getItem(position);
             String name=m.getText();
             String id=m.getId();
            }
        });
