我的应用程序使用应用内搜索，动态建立每个请求的搜索建议，将它们放入MatrixCursor并返回要显示的建议。在这里搜索建议信息：
http://developer.android.com/guide/topics/search/adding-custom-suggestions.html搜索建议失败2.2
这个工作在2.1 UPDATE1完全正常，但是当我装好了一个2.2的手机上，我得到一个致命的错误，当我尝试搜索。下面是相关的日志：

其中“我的字符串信息”是第一个（在这种情况下，仅）行的SUGGEST_COLUMN_TEXT_1字段的值将被返回作为光标的建议。堆栈跟踪根本不触碰我的代码，并且在调试器中跟踪它，显示在我的搜索建议内容提供程序中返回建议光标后的一段时间内发生错误。
为什么他们的适配器突然尝试将字符串解释为长整型？有人遇到过这种情况么？
谢谢！
这是问题所在。当我得到的代码有一个字符串（与text1相同的字符串）进入ID，但它并不重要，并在2.1它工作，所以我刚刚离开它。显然在2.2上，它被强制执行为一个Long。 – 2010-07-23 21:01:23
我也面临同样的问题在android 2.2，请提供一些更多的信息来解决这个问题。请 – 2010-10-22 15:30:38
