Question

用户在自动填充文本框中键入2个字母
这两个字母被保存并用于Web服务方法中检索以这两个字母开头的所有用户
返回XML结果，并进行解析，然后检索用户名+ id和将每个保存在不同的ArrayList
来自名字arraylist get的结果放入一个下拉列表（自动完成列表）
用户从下拉列表项

- 我需要在下拉列表中显示名称，但是，当用户选择名称时，应选择该用户ID并将其另存为String以便用于其他查询。

问题是：如何显示名称，但选择该名称的ID

    AutoCompleteTextView assigneeInput;
    assigneeInput=(AutoCompleteTextView)

    findViewById(id.editassignee);

    assigneeInput.addTextChangedListener(new

    TextWatcher() {

        @Override
        public void onTextChanged (CharSequence s,int start, int before, int count){
            getContactsForAssignee();
        }
        @Override
        public void beforeTextChanged (CharSequence s,int start, int count, int after){
        }
        @Override
        public void afterTextChanged (Editable s){
        }
    }

    );
    //Textwatcher for assignee input -end

}

    //Method to get Contacts for the assignee autocomplete - Start
    public void getContactsForAssignee() {
        //webservice call method

    }
//Method to get Contacts for the assignee autocomplete - End

    public void receiveResults10(String result10) {

        try {

            //Dom parsing set up

            List<String> valSetOne = new ArrayList<String>();
            List<String> valSetTwo = new ArrayList<String>();
            ArrayList<HashMap<String, String>> menuItems = new ArrayList<HashMap<String, String>>();


            for (int i = 0; i < nodesUDSObjectList.getLength(); i++) {
                Element elementUDSObject = (Element) nodesUDSObjectList.item(i);
                NodeList nodesAttributeList = elementUDSObject.getElementsByTagName("Attribute");

                HashMap<String, String> mapp = new HashMap<String, String>();


                for (int iA = 0; iA < nodesAttributeList.getLength(); iA++) {
                    Element elementAttribute = (Element) nodesAttributeList.item(iA);
                    //You have attribute(iA)


                    NodeList AttrNameElementList = (NodeList) elementAttribute.getElementsByTagName("AttrName");
                    String nameValue = getCharacterDataFromElement((Element) (AttrNameElementList.item(0)));

                    System.out.println("name" + nameValue);

                    NodeList AttrValueElementList = (NodeList) elementAttribute.getElementsByTagName("AttrValue");
                    String valueValue = getCharacterDataFromElement((Element) (AttrValueElementList.item(0)));

                    if (nameValue.equals("name")) {
                        valSetOne.add(valueValue);
                        mapp.put(COMBO_NAME, valueValue);
                    }
                    if (nameValue.equals("id")) {
                        valSetTwo.add(valueValue);
                        mapp.put(PERSISTENT_ID, valueValue);
                    }
                }
                menuItems.add(mapp);
            }
            AutoCompleteTextView editAssignee;
            ArrayAdapter<String> adapter;

            adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, valSetOne);
            editAssignee = (AutoCompleteTextView) findViewById(R.id.editassignee);
            editAssignee.setAdapter(adapter);

        } catch (Exception e) {

            e.printStackTrace();


        }

    }

    public static String getCharacterDataFromElement(Element e) {

    }

    //Beginning of method to actually save the ticket executed on click of the "save" button
    public void SaveThisIncident(View v) {
        AutoCompleteTextView editAssigneeInput = (AutoCompleteTextView) findViewById(R.id.editassignee); //receiving the users input for assignee
        String thisIsAssignee = editAssigneeInput.getText().toString();
    }

Answer 1

您需要为AutoCompleteTextView editAssignee设置itemclicklistner＆amp;使用BaseAdapter代替ArrayAdapter。

传递自定义对象的ArrayList，其中包含id＆amp;字符串值到baseadapter。

自定义对象可以是

public class item{
String id;
String value;
}

现在onClickItem你可以同时获得id＆amp;来自你的Arraylist的价值

显示值，但从下拉列表中选择一个id
