如何文本过滤由 SimpleCursorAdapter 支持的 Android ListView? [英] How to text filter an Android ListView backed by a SimpleCursorAdapter?
问题描述
我有一个由 SimpleCursorAdapter 支持的 ListView.
I have a ListView that is backed by a SimpleCursorAdapter.
我希望能够像过滤联系人列表一样过滤列表，只需输入即可，然后我遇到了 textFilterEnabled()
I'd like to be able to filter the list like you would a contacts list, just by typing, and I came across the textFilterEnabled()
问题是，我不知道如何让它与 SimpleCursorAdapter 一起工作.
Problem is, I couldn't see how to get it to work with a SimpleCursorAdapter.
这甚至可能吗?
如果有，是怎么做的?
Is this even possible?
If so, how is it done?

setTextFilterEnabled() 方法不会自动实现过滤，因为它不知道什么在您的 Cursor 中，应过滤文本.
The setTextFilterEnabled() method doesn't automatically implement filtering, as it doesn't know what in your Cursor the text should be filtered against.
