Question

我正在构建一个应用程序，我希望能够通过AutoCompleteTextView输入联系人的姓名，然后在选择联系人后，我希望能够将该联系人添加到ListView 。到目前为止，我已经能够通过以下代码通过自动完成功能接收联系人姓名，电话号码和类型：

public class UserContactActivity extends Activity {

    private ArrayList<Map<String, String>> mPeopleList;

    private SimpleAdapter mAdapter;
    private AutoCompleteTextView mTxtPhoneNo;

    /** Called when the activity is first created. */

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_user_contacts);

        mPeopleList = new ArrayList<Map<String, String>>();
        PopulatePeopleList();
        mTxtPhoneNo = (AutoCompleteTextView) findViewById(R.id.mmWhoNo);

        mAdapter = new SimpleAdapter(this, mPeopleList, R.layout.custcontview ,new String[] { "Name", "Phone" , "Type" }, new int[] { R.id.ccontName, R.id.ccontNo, R.id.ccontType });

        mTxtPhoneNo.setAdapter(mAdapter);

        // This is the button that updates the user's list of emergency contacts
        //Button btnSimple = (button) findViewById(R.id.btnSimple);

        //btnSimple.setOnClickListener(new OnClickListener() {
            //public void onClick(View v) (
                // adds contact
                //.notifyDataSetChanged();

    }

    //}

    public void PopulatePeopleList()
    {

        mPeopleList.clear();

        Cursor people = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);

        while (people.moveToNext())
        {
            String contactName = people.getString(people.getColumnIndex(
            ContactsContract.Contacts.DISPLAY_NAME));

            String contactId = people.getString(people.getColumnIndex(
              ContactsContract.Contacts._ID));
            String hasPhone = people.getString(people.getColumnIndex(
              ContactsContract.Contacts.HAS_PHONE_NUMBER));

            if ((Integer.parseInt(hasPhone) > 0))
            {

                 // You know have the number so now query it like this
                Cursor phones = getContentResolver().query(
                  ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
                  null,
                  ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ contactId,
                  null, null);
                while (phones.moveToNext()) {

                    //store numbers and display a dialog letting the user select which.
                    String phoneNumber = phones.getString(
                    phones.getColumnIndex(
                      ContactsContract.CommonDataKinds.Phone.NUMBER));

                    String numberType = phones.getString(phones.getColumnIndex(
                      ContactsContract.CommonDataKinds.Phone.TYPE));

                    Map<String, String> NamePhoneType = new HashMap<String, String>();

                    NamePhoneType.put("Name", contactName);
                    NamePhoneType.put("Phone", phoneNumber);

                    if(numberType.equals("0"))
                        NamePhoneType.put("Type", "Work");
                    else
                        if(numberType.equals("1"))
                            NamePhoneType.put("Type", "Home");
                        else if(numberType.equals("2"))
                            NamePhoneType.put("Type",  "Mobile");
                        else
                            NamePhoneType.put("Type", "Other");

                    //Then add this map to the list.
                    mPeopleList.add(NamePhoneType);
                }
                phones.close();
            }
        }
        people.close();

现在我希望能够将所选联系人添加到列表视图中，只显示他们的姓名和号码。这是我当前的java文件，其中包含arrayadapter和list：

public class MainActivity extends Activity {

    final ArrayList<String> phoneList = new ArrayList<String>();

        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);

            ListView myListView = (ListView)findViewById(R.id.myListView);
            final EditText myEditText = (EditText)findViewById(R.id.myEditText);
            final ArrayList<String> phoneList = new ArrayList<String>();
            final ArrayAdapter<String> aa;

            aa=new ArrayAdapter<String>(this, R.layout.custom_list_item, R.id.phoneName, phoneList);
            myListView.setAdapter(aa);

            Button btnSimple = (Button) findViewById(R.id.btnSimple);
            btnSimple.setOnClickListener(new OnClickListener() {
                public void onClick(View v) {
                    //adds contact
                    phoneList.add(0, myEditText.getText().toString());
                    //update the view
                    aa.notifyDataSetChanged();
                    //erases text to add phone
                    myEditText.setText("");
                }
            });
        }
    }

很抱歉，这是一个简单的问题。我是Android的编程新手，但一直试图让它工作好几天。非常感谢任何帮助，谢谢你们。

而不是使用ArrayAdapter，您可以使用BaseAdapter并传递自定义Listview单元格布局。或者将ArrayAdapter扩展到您自己的cudtom类。并夸大你的布局。
