在MultiAutoCompleteTextView上应用样式

Question

我试图在MultiAutocompleteTextView上应用样式，但该样式似乎未应用。

在风格上。我有以下xml（仅显示一部分）：

<style name="AppTheme" parent="android:Theme.Light">
    <item name="android:buttonStyle">@style/Button</item>
    <item name="android:imageButtonStyle">@style/ImageButton</item>
    <item name="android:editTextStyle">@style/Edit</item>
    <item name="android:autoCompleteTextViewStyle">@style/AutoCompleteTextView</item>
    <!-- In the line above I tried to set "android:multiAutoCompleteTextViewStyle" but that doesn't seem to work. My guess is that it is because MultiAutoCompleteTextView is a subclass of AutoCompleteTextView -->
</style>

...

<style name="AutoCompleteTextView" parent="@android:style/Widget.AutoCompleteTextView">
    <item name="android:completionHintView">@layout/completion_hint</item>
    <item name="android:background">@drawable/edit</item>
    <item name="android:layout_width">fill_parent</item>
    <item name="android:layout_height">wrap_content</item>
    <item name="android:layout_marginBottom">5dp</item>
    <item name="android:layout_marginLeft">5dp</item>
    <item name="android:layout_marginRight">5dp</item>
    <item name="android:layout_marginTop">5dp</item>
    <item name="android:ems">10</item>
    <item name="android:gravity">top</item>
    <item name="android:lines">1</item>
    <item name="android:singleLine">true</item>
    <item name="android:textColor">@color/black</item>
</style>`

在我的布局文件中，我有以下内容：

<MultiAutoCompleteTextView
    android:id="@+id/multiAutoCompleteTextView1"
    android:visibility="gone" />

因为主题应用于整个应用程序，所以它也应该应用于MultiAutocompleteTextView。但当我尝试执行应用程序时，会出现以下错误：

12-03 02:00:34.398: E/AndroidRuntime(591): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.myapp/com.example.myapp.MyActivity}: java.lang.RuntimeException: Binary XML file line #37: You must supply a layout_width attribute.

重写主题或样式时，只能重写样式声明的指定属性。布局属性未在小部件中声明。AutoCompleteTextView，您应该为指定视图放置布局
