AutoCompleteTextView 搜索单词的一部分而不是完整的单词 [英] AutoCompleteTextView search part of word instead of full word

问题描述

我有一个 AutoCompleteTextView，它运行良好，直到我在输入中添加一个空格.如果我有很多历史事件的清单(不列颠之战(1940 年)、突出部战役(1944 年)、[插入许多战斗]、拿破仑的致命行军(1812 年)、[插入许多其他历史事件]).

I have an AutoCompleteTextView, and it works nicely, until I add a space to my input. If I had, say, a list of many historical events (Battle of Britain (1940), Battle of the Bulge (1944), [insert lots of battles], Napoleon's fatal march (1812), [insert lots other historical events]).

当我输入Battle"或battle"时，我会得到所有战斗的列表(虽然似乎有一个最大值)，当我输入"britain"，结果中出现不列颠之战(1940)".

When I enter "Battle" or "battle", I get a list of all battles (although it seems there is a max), and when I enter "britain", the "Battle of Britain (1940)" appears in the results.

然而，当我输入 "1940" 时，该列表是空的，原因与当我输入 "itain" 时我没有得到任何点击的原因相同.我猜这个空间是某种分隔符或锚点.如果我将 1940 放在字符串前面(例如 "1940 - Battle of British")并输入19"，我do得到所有结果以19"开头.

However, when I enter "1940", the list is empty, for the same reason that when I enter "itain" I don't get any hits. I guess the space is some sort of separator or anchor. If I put 1940 in front of the String (like "1940 - Battle of Britain") and enter "19", I do get all the results starting with "19".

是否可以让 AutoCompleteTextView 自动完成，即使搜索的单词/短语/部分前面有一个字符?(所以当我输入1940"时，结果中会出现不列颠之战(1940)"?)

Is it possible to have the AutoCompleteTextView autocomplete even when there's a character in front of the searched word/phrase/part? (So when I enter "1940", "Battle of Britain (1940)" will be amongst the results?)

推荐答案

使用实现 Filterable，在 getFilter() 方法中.使用 String.contains() 满足您的要求

Use a custom Adapter which implements Filterable, in the getFilter() method . Use String.contains() for your requirement
