ActionBar text color
ActionBar background image
我想自定义的最后一块是后退按钮图像.默认情况下它是灰色的，我希望它是白色的.更改颜色、指定可绘制对象或简单地使其透明(并将 V 形添加到我的自定义徽标图像)都可以.我该怎么做?
The last piece I want to customize is the back button image. It's grey by default and I would like it to be white. Either changing the color, specifying a drawable or simply making it transparent (and adding the chevron to my customized logo image) would work. How do I go about that?
推荐答案
向上"可见性指示器由主题的 homeAsUpIndicator 属性中指定的可绘制对象提供.要使用您自己的自定义版本覆盖它，它将是这样的:
The "up" affordance indicator is provided by a drawable specified in the homeAsUpIndicator attribute of the theme. To override it with your own custom version it would be something like this:
<style name="Theme.MyFancyTheme" parent="android:Theme.Holo">
<item name="android:homeAsUpIndicator">@drawable/my_fancy_up_indicator</item>
</style>
如果您的应用程序支持 3.0 之前的版本，请确保将此版本的自定义主题放在 values-v11 或类似文件中.
If you are supporting pre-3.0 with your application be sure you put this version of the custom theme in values-v11 or similar.
