運行在2.2錯誤的片段 - 找不到類

我想讓我的應用向後兼容到Android 2.2。運行在2.2錯誤的片段 - 找不到類

我已經有碎片，ListFragments，FragmentPagerAdapter和ActionBarSherlock都發生了。

我已經得到了包括Android的支持庫，並構建完美的作品在我的Android 4.1設備上，但在2.2設備上，我得到如下：

我一直在玩弄這幾個小時，但我只是不知道該怎麼嘗試。任何建議表示讚賞。如果您需要查看一些代碼，請告訴我。

謝謝。

如果沒有看到代碼，我們所能做的只是猜測......您是使用'getSupportFragmentManager'還是'getFragmentManager'？對於使用支持庫，您應該使用前者...以及「FragmentActivity」而不是簡單的「Activity」。 – Barak

我正在使用getSupportFragmentManager。我很抱歉在所有這段時間試圖解決這個問題後，在這裏查看堆棧跟蹤給了我一些額外的提示 - 我剛剛解決了這個問題..我非常確定ActionBarSherlock不支持SearchView $ OnQueryTextListener，所以我把它拿出來，現在它工作正常。我明天會給出正確的答案 - 我必須睡覺！ –

我讀我自己的SO問題後意識到，我並沒有解釋corrsctly如下：

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

看來，ActionBarSherlock不支持onQueryTextListener，以及其他一些因素。無論如何，我並不需要這些方法，所以我將它們從禮拜中刪除，問題就解決了。

我想在4.1設備本身支持onQueryTextChange，但在2.2設備（ActionBar由ActionBarsherlock支持），這些方法不受支持。
