如何将可搜索项的EditText中的文本小写? [英] How to lowercase the text in the EditText of the searchable item?

问题描述

我在Android项目中使用带有建议的可搜索项目.它本质上是一个EditText

I'm using a searchable item with suggestion in my Android project. It is essentially an EditText

<searchable xmlns:android="http://schemas.android.com/apk/res/android"
    android:label="@string/app_name"
    android:hint="@string/search.hint" 
    android:includeInGlobalSearch="true"
    android:searchSettingsDescription="@string/search.hint"
    android:searchSuggestAuthority="com.xxx.android.provider.SearchSuggestionsProvider"
    android:searchSuggestSelection=" ?"
    android:inputType="text"
    android:imeOptions="actionSearch">
</searchable>

当我开始键入时，它显示为首字母大写.为什么?我希望它以小写开头.有可能吗?

When I start typing it shows as first letter uppercase. Why? I would like it to start lowercase. Is it possible?

推荐答案

我很惊讶还没有一个好的答案.也许是我找不到另一个问题.

I'm surprised there isn't a good answer for this yet. Or maybe it's on another question that I couldn't find.

这是我的解决方法.

editText.setFilters(new InputFilter[] {
    new InputFilter.AllCaps() {
        @Override
        public CharSequence filter(CharSequence source, int start, int end, Spanned dest, int dstart, int dend) {
            return String.valueOf(source).toLowerCase();
        }
    }
});

无论如何， editText 中的所有文本均为小写.

All text in editText will be lowercase, no matter what.

您可以根据需要修改字符串.
例如:您希望所有文本都小写并且不允许使用空格(假设这是电子邮件输入字段)

You can modify the string however you like.
For example: you want all text to be lowercase AND no spaces allowed (let's say it's an email input field)

您可以这样替换 return ... :

return String.valueOf(source).toLowerCase().replace(" ", "");

以相同的方式允许或拒绝单个字符.
本示例将所有 e 或 E 替换为 3 .

The same way you can allow or reject individual characters.
This example replaces all e or E with 3.

return String.valueOf(source).replace("e", "3").replace("E", "3");

以此类推.

我希望这对某人有帮助.
