Android MultiAutoCompleteTextView检索多个联系人

Question

我想修改一个代码，我已经看到了一个AutoCompleteTextView的stackoverflow，以便我会返回MultiAutoCompleteTextView多联系人。

但是，当我将其加载到我的Android手机上时，我再也看不到任何可供选择的建议。我感觉问题在于ArrayAdapter初始化，但我无法弄清楚它有什么问题。

在此先感谢您的帮助。

我有以下代码为我multiautocompletetextview：

<MultiAutoCompleteTextView 
    android:id="@+id/mmWhoNo" 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:textColor="#0000A0" 
    android:hint="Choose your Contacts" /> 

最后，我有以下阅读我的接触，我已采取从selecting contact from autocomplete textview与修改一点点。

private ArrayList<Map<String, String>> mPeopleList; 
private ArrayAdapter mAdapter; 
private MultiAutoCompleteTextView mTxtPhoneNo; 

     mPeopleList = new ArrayList<Map<String, String>>(); 
     PopulatePeopleList(); 
    mTxtPhoneNo = (MultiAutoCompleteTextView) findViewById(R.id.mmWhoNo); 
    mTxtPhoneNo.setTokenizer(new MultiAutoCompleteTextView.CommaTokenizer()); 
    mTxtPhoneNo.setThreshold(1); 

      //just to check to see that mPeopleList is being populated 
    Log.i("Multiplecontacts",mPeopleList.get(0).toString()); 


    mAdapter = new ArrayAdapter<ArrayList<Map<String,String>>>(this, android.R.layout.simple_dropdown_item_1line); 
    mAdapter.add(mPeopleList); 

    mTxtPhoneNo.setAdapter(mAdapter); 

    mTxtPhoneNo 
      .setOnItemClickListener(new OnItemClickListener() { 

       @Override 
       public void onItemClick(AdapterView<?> av, View arg1, 
         int index, long arg3) { 
        // TODO Auto-generated method stub 
        Map<String, String> map = (Map<String, String>) av 
          .getItemAtPosition(index); 

        String name = map.get("Name"); 
        String number = map.get("Phone"); 
        mTxtPhoneNo.setText("" + name + "<" + number + ">,"); 

       } 


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(); 
    startManagingCursor(people); 
} 

      });

您所遇到的问题是因为您使用的是ArrayAdaptor。您正在给它一张选择地图的列表，但没有关于如何过滤或比较地图对象与输入文本的数据。我用一个SimpleAdapter来代替，它工作正常。

mTxtPhoneNo = (MultiAutoCompleteTextView) findViewById(R.id.multiAutoCompleteTextViewContactsNames); 
mAdapter = new SimpleAdapter(this, mPeopleList, R.layout.costom_contact_view, new String[] { "Name", "Phone", "Type" }, new int[] { 
          R.id.ccontName, R.id.ccontNo, R.id.ccontType }); 
mTxtPhoneNo.setThreshold(1); 
mTxtPhoneNo.setAdapter(mAdapter); 
mTxtPhoneNo.setTokenizer(new MultiAutoCompleteTextView.CommaTokenizer()); 
mTxtPhoneNo.setOnItemClickListener(multiAutoContactNamesListener); 

此外，在你的OnClickListener一定要连接的联系人的名字。 变化：

mTxtPhoneNo.setText("" + name + "<" + number + ">,"); 

要：

mTxtPhoneNo.append(", " + name + " <" + number + ">"); 

希望这有助于。

我所做的是，而不是使用我的ArrayAdapter类型ArrayList<Map<String, String>>，我创建了一个名为ContactsInfo类，然后创建ArrayAdapter<ContactsInfo>。

而且同样我把我的ArrayList<Map<String, String>>更改为ArrayList<ContactsInfo>，它工作。

此外，您还必须覆盖ContactsInfo类中的toString方法。
