In order for AutoCompleteTextView to rise up

<android.support.design.widget.TextInputLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    >

    <AutoCompleteTextView
        android:id="@+id/auto_text"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:enabled="false"
        android:hint="Текст"

        android:singleLine="true"/>

</android.support.design.widget.TextInputLayout>
