动作条的文字颜色

动作条的背景图片

我想自定义的最后一块是后退按钮图像。这是灰色默认情况下，我想它是白色的。要么改变颜色，指定绘制或者干脆使其透明（并加入了雪佛龙到我的自定义徽标图像）会工作。我怎么去的？提前致谢！

The last piece I want to customize is the backbutton 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? Thanks in advance!

推荐答案

向上的启示指标是由主题的 homeAsUpIndicator 属性指定的绘制提供。要使用自己的自定义的版本覆盖它会是这样的：

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>

如果您是支持pre-3.0与您的应用程序可以肯定你把这个版本的自定义主题的值-V11 或类似的。

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.
