Android的菜单项切换按钮 [英] Android MenuItem Toggle Button
问题描述
在我的Android应用程序，我想设置为可切换的，在它的菜单，如拨号应用程序做的扬声器和静音。你可以看到下面的图片：
In my Android application, I want a setting to be toggleable in it's menu like the Dialer app does for speaker and mute. You can see a picture below:
您看到的扬声器，静音和保持选项切换按钮 - 您可以再次点击他们，他们将切换绿的颜色。他们可以这样做，在一个自定义的方式，但我怀疑它是一个选项（我尝试设置可检查的属性）。
You see how the Speaker, Mute and Hold options are toggle buttons - you can tap them again and they will toggle the green color. They may do this in a custom way, but I suspect it is a option (I tried setting the Checkable attribute).
推荐答案
这看起来是这样的菜单项实现自定义视图。
It's looks like this menu item is implemented as a custom view.
在Android源$ C $ C，你可以看看<一href="http://grep$c$c.com/file/repository.grep$c$c.com/java/ext/com.google.android/android-apps/2.0_r1/com/android/phone/InCallMenuView.java"相对=nofollow> com.android.phone.InCallMenuView.java 来看看这是如何实现的。
In the android source code you can take a look at com.android.phone.InCallMenuView.java to see how this is implemented.
它看起来并不像它的公共API的一部分，但它看起来pretty的自足。如果你的项目有一个兼容的许可，您可以在您认为合适将它复制到你的项目和使用和修改它。
It doesn't look like it is part of the public API, but it looks pretty self-contained. If your project has a compatible license, you may be able to copy it into your project and use and modify it as you see fit.
