我会通过谷歌提供了与它的SDK此示例包。我试图改变API级至7指出，有项目许多悬而未决的错误。

I was going through this sample package which Google has provided with it's sdk. I tried changing the api level to 7 and observed that there were many unresolved errors in the project.

我列出了几个位置：

在ICE_CREAM_SANDWICH不能得到解决或不是场（ActionBarActivity.java） 研究不能被解析为一个变量（这可能是由于这样的事实，我的XML也包含错误） 在SHOW_AS_ACTION_IF_ROOM不能得到解决或不是场（ActionBarHelperBase.java） 的方法setActionView（视图）是未定义的类型菜单项（ActionBarHelperHoneycomb.java） 的方法getActionBar（）是未定义的类型的活动（ActionBarHelperICS.java） 进口android.view.ActionProvider不能被解析（SimpleMenuItem.java） 在RES /值-V13 / styles.xml - 错误：错误检索父项：未发现的资源匹配给定名称机器人：款式/ TextAppearance.Holo.Widget.ActionBar.Title。 错误：错误：未发现的资源匹配给定名称：ATTR机器人：actionBarStyle。 （在RES /值-V11 / styles.xml） ICE_CREAM_SANDWICH cannot be resolved or is not a field (ActionBarActivity.java) R cannot be resolved to a variable (This is probably due to the fact my xml also contains errors) SHOW_AS_ACTION_IF_ROOM cannot be resolved or is not a field (ActionBarHelperBase.java) The method setActionView(View) is undefined for the type MenuItem (ActionBarHelperHoneycomb.java) The method getActionBar() is undefined for the type Activity (ActionBarHelperICS.java) The import android.view.ActionProvider cannot be resolved (SimpleMenuItem.java) in res/values-v13/styles.xml - error: Error retrieving parent for item: No resource found that matches the given name 'android:style/ TextAppearance.Holo.Widget.ActionBar.Title'. error: Error: No resource found that matches the given name: attr 'android:actionBarStyle'. (in res/values-v11/styles.xml)

不知道如何摆脱这些错误的？基本上，我针对Android设备2.x及更高版本。是否使用actionbarsherlock是另一种选择？我在这里读了一些关于后2.x的Andr​​oid设备的操作栏兼容包工程为好。

Any idea how to get rid of these errors? Basically I'm targeting android devices 2.x and later. Does using actionbarsherlock is another alternative? I read here on some post that action bar compatibility package works on 2.x android devices as well.

推荐答案

您不应该改变的API版本。该清单声明最小的SDK版本为4，这意味着它将工作在2.x的设备。尝试在模拟器上加载它，使用API​​版本14编译。

You shouldn't change the api version. The manifest declares min-sdk-version as 4, which means it will work on 2.x devices. Try loading it on the emulator, using api version 14 to compile.
