android - 在 2.2 错误上运行 fragment - 找不到类

Question

我正在尝试使我的应用向后兼容 Android 2.2。

我有 Fragments、ListFragments、FragmentPagerAdapter 和 ActionBarSherlock 都在发生。

我已经包含了 android 支持库，并且构建在我的 android 4.1 设备上完美运行，但在 2.2 设备上，我得到以下信息:

我已经研究了好几个小时了，但我就是不知道该尝试什么。任何建议表示赞赏。如果您需要查看一些代码，请告诉我。

谢谢。

Answer 1

我在阅读自己的 SO 问题后意识到，我没有正确解释以下内容:

09-21 00:10:32.867: I/dalvikvm(1229): Failed resolving Lanother/music/player/AlbumListFragment; interface 521 'Landroid/widget/SearchView$OnQueryTextListener;

ActionBarSherlock 似乎不支持 onQueryTextListener 和其他一些元素。反正我不需要这些方法，所以我把它们从ativity中去掉，问题就解决了。

我想 4.1 设备原生支持 onQueryTextChange，但在 2.2 设备上(ActionBarsherlock 支持 actionBar)，这些方法不受支持。
