推荐答案

我知道如何可以做到这一点。在你的Andr​​oidManifest.xml中，需要指定类似如下：

I figured out how this can be done. In your AndroidManifest.xml, you need to specify something like the following:

<uses-sdk android:minSdkVersion="8"
          android:targetSdkVersion="14" />

基本上，的minSdkVersion 是最小的Andr​​oid SDK版本，您的应用程序支持（在我的情况下，2.2）和 targetSdkVersion 为你打靶的版本（即你的preferred的版本 - 在我的情况，这是4.0）

Basically, minSdkVersion is the minimum Android SDK version that you application supports (in my case, 2.2) and targetSdkVersion is the version you're "targetting" (i.e. your "preferred" version - in my case, that's 4.0)

在默认情况下， targetSdkVersion 是一样的的minSdkVersion ，如果你离开了pre-蜂窝，你基本上是告诉机器人，你的应用程序是遗产，它会始终显示菜单按钮。

By default, targetSdkVersion is the same as minSdkVersion, and if you leave that pre-Honeycomb, you're basically telling Android that your app is "legacy" and it'll always show the menu button.

如果你让 targetSdkVersion 后蜂窝，然后选择菜单按钮才会显示，如果你确实有菜单项中定义。

If you make targetSdkVersion post-Honeycomb, then the menu button will only be shown if you actually have menu items defined.
