我想用一个选择自定义我的动作栏项目的背景下，以覆盖显示什么时候按钮pssed $ P $。 这是pretty的易于使用的菜单键（例如，溢图标），你可以用 actionBarItemBackground 他们的风格。

I'm trying to customize the background of my action bar items with a selector, to override what is shown when the button is pressed. This was pretty easy with menu buttons (e.g., overflow icon), as you can style them with actionBarItemBackground .

可悲的是，这并不适用于向上/家庭/左指标。我已经试过失败，在我的styles.xml：

Sadly this does not apply for the up/home/left indicator. I have unsuccessfully tried, in my styles.xml:

＆LT;项目名称=actionButtonStyle＆GT; ;

＆LT;项目名称=actionBarStyle＆GT; ;

＆LT;项目名称=toolbarStyle＆GT; ;

没有的嵌套属性似乎作用于首页图标的背景。我还搜查了android.R.attr，给了一看这个。有什么办法？

None of the nested attributes seem to act on the home icon background. I also searched over android.R.attr and gave a look at this. Is there any way?

我想留在向上的指标，没有膨胀的自定义视图。在这种情况下，我也有夸大的标题以及自定义视图自然地出现在标题末尾。我会失去汉堡到箭头动画，我会好好关心利润和设计指南（现在 AppCompat 管理​​），以及其他一些不好的事情上的方式。

I would like to stay with the "up" indicator, without inflating a custom view. In that case, I would also have to inflate the title as well as custom views naturally appear at the end of the title. AND I would lose the burger-to-arrow animation, AND I would have to take care about margins and design guidelines (now managed by AppCompat), and some other bad thing on the way.

我想过设置标志，但会有一定的并发症，以及，我不认为我可以无论如何改变背景。

I thought about setting a Logo, but that would have some complications as well and I don't think I could change the background anyway.

我想到了工具栏是一个布局，所以我可以从XML把自定义视图在里面。如果我没有错，他们的标题后出现，所以这也不是一个好主意。

I thought about Toolbar being a Layout, so I could put custom views in it from XML. If I'm not wrong they appear after the title, so neither this is a good idea.

我该怎么办？
