我应用了一个程序,它从 2.1 和 。但我的应用程序有退出应用程序的菜单功能。我安装了冰红三明治(ICS, 4. 0 版本)设备,操作正常。但是, ICS 没有菜单按钮 - 而不是这个按钮。 我对这个概念很新。 我想将它融入我的应用程序。 我尝试过,但我没有成功。

android:targetSdkVersion="11" in the Android manifest.android:showAsAction="ifRoom|withText" --> add to menu.xml (which is in the menu folder) but I get the following error:找不到用于 属性显示显示的资源标识符。 As As As Action in pack and mid

设置 目标SdkVersion :
打开您的工程属性, 选择 Android, 并选择一个 Android SDK 来连接您的工程。 对于工程属性和您的 < a href=> http:// developmenter.android.com/ guide/ optics/ fundamentals.html# Manifest" rel = “ nofollow norefererr” >Android宣言 targetSdkVersion , 我建议使用最新的 SDK 。

minSdkVersion 定义了该应用程序将运行的最低版本的Android 。 targetSdkVersion 定义了该应用程序所知道的最高版本的Android, 该应用程序何时构建 -- -- 哪些类别和方法可供使用,哪些常数可定义,等等。 它可能在更新版本中运行, 但不会知道在 targetSdkVersion 之后添加的任何特性 。
如果您想要在 Android & lt; 3. 0 上显示一个动作栏, 请在 < a href=" http:// actionbarsherlock.com/" rel=" no follown norefreerr" > Action Bar Sherlock 或 < a href=" "http:// developer.android.com/resources/samples/ ActionBarCompat/index. html" rel= "nofollown noreferr" > > Action Bar Complitibility SDK的样本上显示一个工程。 但是在您对您的动作栏在 & gt; = 3. 0 中感到舒适之前, 不要尝试它 。
