推荐答案
要实现指数的滚动,你必须调用 setFastScrollEnabled(真)
您的ListView。此外,您的适配器必须实现<一个href="http://developer.android.com/reference/android/widget/SectionIndexer.html"><$c$c>SectionIndexer$c$c>接口。
To implement index scrolling, you have to call setFastScrollEnabled(true)
on your ListView. In addition, your adapter has to implement the SectionIndexer
interface.
您可以在这里找到一个例子:<一href="http://spinettaro.blogspot.de/2011/11/android-snippet-$c$c-android-listview.html">http://spinettaro.blogspot.de/2011/11/android-snippet-$c$c-android-listview.html
You can find an example here: http://spinettaro.blogspot.de/2011/11/android-snippet-code-android-listview.html
这应该与所有的子类浏览 AbsListView
。
This should work with all Views that are a subclass of AbsListView
.
