推荐答案

我的微调器中有很多物品

I have a spinner with huge amount of items

这是您的问题的一部分. :)认为微调器类似于桌面或Web UI中的下拉框.没有用户愿意使用它来搜索大量项目".那不是他们的目的.

This is part of your problem. :) Think of Spinners as being similar to dropdown boxes in desktop or web UIs. No user wants to use one to search through "a huge amount of items." That's not what they're for.

考虑将这个特定的选择过程分解为自己的对话框，甚至可能分解为自己的活动.从那里，您可以提供一个更丰富的界面来进行此选择，其中可能包括启用了快速滚动的ListView(如果适配器实现

Consider breaking out this particular selection process into its own Dialog or possibly even its own Activity. From there you can offer a much richer interface for making this choice, which might include a ListView with fast scrolling enabled, (if the adapter implements SectionIndexer then fast scrolling will let the user jump between sections easily,) and maybe a permanent text field so that the user can live-filter content down to something more manageable.
