我有一个问题在我的行动吧，我在试图建立一个搜索视图就可以了为了获得AA搜索栏扩展。

I have a problem on my Action bar, I tried to setup a search view on it in order to get a a search bar expandable.

这是沃金也只是一个事实，我不得不将所有的选项 ifRoom 其他菜单项，以便让搜索领域采取所有房间的时候，搜索图标点击。

This is woking well except the fact that I had to set all the other menu items with the option ifRoom in order to let the search field take all the room when the search icon is clicked.

这部分还运作良好，除了一个事实，即过多的菜单项得到了推入菜单溢出，只有2个图标仍然是垂直屏幕上（包括搜索栏）。

This part also worked well except the fact that too many menu items got pushed into the menu overflow, only 2 icons remained on the vertical screen (including the search bar).

我做了另一项活动有5菜单项，另一项测试：

I did another test on another activity having 5 menu items:

下面是结果：

案例1：

案例2：

为什么，如果我使用 ifRoom ，只显示2个图标，而实际上5可以随便填的地方？

Why if I use ifRoom, only 2 icons are displayed while actually 5 could easily fill the place?

这一点，因为，我有我的搜索视图项旁边只提供一个菜单项...

Because of this, I have only one menu item available beside my search view item...

谢谢！

看起来像它的设计决定：

Looks like its a design decision:

杰克沃顿说：

当包含在操作栏中有一个有限的最多   基于设备的密度无关宽度操作项。该   操作项也不能覆盖的动作一半以上的宽度   吧。

When contained within the action bar there is a finite maximum of action items based on the device's density-independent width. The action items can also not cover more than half the width of the action bar.
