setFastScrollEnabled在Honeycomb平板电脑上适用于我所有的手机和崩溃

我最近得到了一个Xoom，我目前正致力于改进我的HoneyComb平板电脑的应用程序。一切都很好，我最后一个问题涉及到一个带FastScroll的ListView到TabActavity。setFastScrollEnabled在Honeycomb平板电脑上适用于我所有的手机和崩溃

this.setListAdapter(mIndexAdapter); 
ListView lv = getListView(); 
lv.setTextFilterEnabled(true); 
//lv.setFastScrollEnabled(true);

此代码在所有手机上工作良好，因为2年，我现在有setFastScrollEnabled的问题！正如你可以看到我的片段，我不得不删除这条线或我得到这个例外（见下文）

任何想法是什么问题？我发现的唯一的解决方法是：

if(android.os.Build.VERSION.SDK_INT<11) 
     lv.setFastScrollEnabled(true);

我可以张贴我的适配器，但我真的不认为这有关。

我见过的错误报道多次在Android 3.1以及3.0.1（在FastScroller.java:609）东西，具有快速滚轮工作之前是不会了。

我看到这个，如果我从getSections（）方法返回null。改变它返回一个空数组，而不是工作（新的字符串[0]）。但是，快速滚动在这种情况下不起作用，就像它在手机上一样。
