android - 删除选择的 native ActionBar 突出显示

Question

我想删除 Android ActionBar 中项目选择的默认突出显示，我正在使用 AppCompat

我尝试通过设置颜色、透明形状或事件可绘制透明 png 将 android:selectableItemBackground 设置为透明，但没有成功

<style name="NActionBar" parent="@android:style/Widget.Holo.Light.ActionBar">
    <item name="android:displayOptions">showHome|homeAsUp|showTitle</item>
    <item name="displayOptions">showHome|homeAsUp|showTitle</item>
    <item name="android:icon">@android:color/transparent</item>
    <item name="android:titleTextStyle">@android:color/white</item>
    <item name="android:selectableItemBackground">@android:color/transparent</item>
    <item name="android:background">@drawable/ab_transparent_example</item>
</style>

Answer 1

actionBarItemBackground 主题属性将允许您更改操作项选择器。

如果您将它与 ActionBarSherlock 或 ActionBarCompat 一起使用，请务必提供带有或不带 android: 前缀的条目。

在您的风格中，您可以使用以下几行:

<item name="android:actionBarItemBackground">@drawable/my_drawable</item>
<item name="actionBarItemBackground">@drawable/my_drawable</item>

希望对你有帮助
