如何强制AutoCompleteTextView更新下拉的高度？ [英] How to force AutoCompleteTextView to update height of drop-down?

问题描述

我在我的应用程序连接到远程站点获取建议有一个 AutoCompleteTextView 。虽然建议是牵强我展现一个项目说搜索，请稍候的列表。请求完成后，我更新的建议列表适配器，并调用 notifyDataSetChanged 。

I have an AutoCompleteTextView in my app that connects to a remote site to fetch suggestions. While suggestions are fetched I show a list of one item saying "searching, please wait". After the request completes, I update the suggestion list adapter and call notifyDataSetChanged.

然后列表内容变为新的建议（如预期），但不知何故列表保持在高度1细胞，因此，只有顶部的建议是可见的。如何强制视图重新计算下拉高度？

Then the list contents changes to new suggestions (as expected), but somehow the list remains 1 cell in height, so that only the top suggestion is visible. How to force the view to re-calculate the dropdown height?

推荐答案

似乎 showDropDown（）势力重新评估推荐列表的高度。不幸的是，它也迫使它来展示，但对于我而言这是可以接受的。

It seems that showDropDown() forces re-evaluation of the suggestion list height. Unfortunately, it also forces it to show, but for my purposes it was acceptable.
