我想做一个MultiAutoCompleteTextView这样的：

我可以检索数组中的联系人号码和数组中的姓名。我该怎么做MultiAutoCompleteTextView？例如，在图片中，如果你输入ca有一个建议，如果你输入22，有相同的建议，它们在另一个之下。我有两个数组numbers[]和names[]一个MultiAutoCompleteTextView。

这是我的代码：

Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,null,null, null);
ArrayList<String> numbers = new ArrayList<String>();
ArrayList<String> names = new ArrayList<String>();

while (phones.moveToNext())
{
     names.add(phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME)));
     numbers.add(phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)));
}
phones.close();
String[] numbersArray = new String[numbers.size()];
String[] namesArray = new String[names.size()];
numbers.toArray(numbersArray);
names.toArray(namesArray);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
         android.R.layout.simple_dropdown_item_1line, namesArray);
MultiAutoCompleteTextView textView = (MultiAutoCompleteTextView)findViewById(R.id.edt_numara);

textView.setTokenizer(new MultiAutoCompleteTextView.CommaTokenizer());
textView.setAdapter(adapter);

但它仅适用于名称和数字未显示。

步骤 1. 在 xml 文件中创建自动完成功能，如下所示

<AutoCompleteTextView android:paddingTop="15dp"
android:id="@+id/txtPhoneNo"
android:focusableInTouchMode="true"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:imeOptions="actionDone"/>

步骤 2. 在您的 Android Mainfeast 文件中添加以下权限以访问联系人

<uses-permission android:name="android.permission.READ_CONTACTS" />

步骤 3. 创建一个 Activity 并在您的 Java 代码中映射 autocompletetextview 组件

public class MyContacts extends Activity {

AutoCompleteTextView txtPhoneNo;


public ArrayList<String> c_Name = new ArrayList<String>();
public ArrayList<String> c_Number = new ArrayList<String>();
String[] name_Val=null;
String[] phone_Val=null;

@Override
public void onCreate(Bundle icicle)
{
super.onCreate(icicle);
txtPhoneNo = (AutoCompleteTextView) findViewById(R.id.txtPhoneNo);

}

第 4 步：使用 ContentReslover 获取联系人，如果您在 Android 1.6 或之前的版本中运行它，请使用人员类获取联系人并将联系人添加到数组列表中，如下所示

ContentResolver cr1 = getContentResolver();

String[] projection = new String[] { People._ID,People.NAME,People.NUMBER };

Uri phone_contacts = People.CONTENT_URI;

Cursor managedCursor = cr1.query(phone_contacts, projection, null, null, People.NAME + " ASC");

if (managedCursor.moveToFirst()) {

String contactname;
String cphoneNumber;
int nameColumn = managedCursor.getColumnIndex(People.NAME);
int phoneColumn = managedCursor.getColumnIndex(People.NUMBER);
Log.d("int Name",Integer.toString(nameColumn));
Log.d("int Number",Integer.toString(phoneColumn));


do {
// Get the field values
contactname = managedCursor.getString(nameColumn);
cphoneNumber = managedCursor.getString(phoneColumn);
if((contactname != " " || contactname != null) && (cphoneNumber!= " " ||cphoneNumber!= null))
{

c_Name.add(contactname);
c_Number.add(cphoneNumber);
}


} while (managedCursor.moveToNext());

}


// Donot use People class if your using android1.6 above

Uri contacts = Uri.parse("content://icc/adn");

Cursor managedCursor1 =cr.query(contacts, null, null, null, null);

if (managedCursor1.moveToFirst()) {

String contactname;
String cphoneNumber;

int nameColumn = managedCursor1.getColumnIndex("name");
int phoneColumn = managedCursor1.getColumnIndex("number");

Log.d("int Name",Integer.toString(nameColumn));
Log.d("int Number",Integer.toString(phoneColumn));


do {
// Get the field values
contactname = managedCursor1.getString(nameColumn);
cphoneNumber = managedCursor1.getString(phoneColumn);
if((contactname != " " || contactname != null) && (cphoneNumber!= " " ||cphoneNumber!= null))
{

c_Name.add(contactname);
c_Number.add(cphoneNumber);
}

} while (managedCursor1.moveToNext());

}

第 5 步：现在将 ArrayList 转换为 Array 并将该 Array 设置为 AutoComplete，如下所示

name_Val = (String[]) c_Name.toArray(new String[c_Name.size()]);
phone_Val= (String[]) c_Number.toArray(new String[c_Name.size()]); ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,android.R.layout.simple_dropdown_item_1line, name_Val);
txtPhoneNo.setAdapter(adapter);
