gmail-> send letter-> tp와 같은 AutocompleteTextView 만들기

Question

gmail -> send letter-> TO와 같이 AutocomplteTextView를 만드는 방법을 말할 수 있습니까? 나는 내 애플 리케이션에서 그것을 만들려고 노력하지만 7 안드로이드에서 매우 나쁜 작품. 내 UI 소스 코드 :

<android.support.design.widget.TextInputLayout 
    style="@style/ABM.TextInputLayout" 
    android:id="@+id/til_receiverName" 
    android:layout_height="wrap_content" 
    android:layout_marginLeft="8dp" 
    android:layout_marginRight="8dp" 
    android:layout_width="match_parent" 
    android:visibility="visible"> 

    <EditText 
     style="@style/EditText.DarkIndigo" 
     android:dropDownAnchor="@id/til_receiverName" 
     android:dropDownHeight="@dimen/auto_complete_text_view_list_size" 
     android:hint="@string/receiver_name" 
     android:id="@+id/receiver_name" 
     android:imeOptions="flagNoExtractUi|actionDone" 
     android:layout_height="wrap_content" 
     android:layout_width="match_parent" 
     android:maxLength="160" 
     android:popupBackground="@android:color/white" 
     android:popupElevation="0dp" /> 
</android.support.design.widget.TextInputLayout>
