android - 错误 : inner element must either be a resource reference or empty?

Question

最近我将我的项目升级到 Android Studio 3.2.1、Gradel 4.6、Gradle Plugin 4.6 和 tagetSDKVersion 28。

但是我在合并的 values.xml 文件中遇到以下错误 -

error: <item> inner element must either be a resource reference or empty.

导致问题的合并 values.xml 中的行 -

<item name="date_picker_day" type="id">false</item>
<item name="date_picker_header" type="id">false</item>
<item name="date_picker_month" type="id">false</item>
<item name="date_picker_month_and_day" type="id">false</item>
<item name="date_picker_year" type="id">false</item>
<item name="day_picker_selected_date_layout" type="id">false</item>
<item name="done" type="id">false</item>
<item name="month_text_view" type="id">false</item>
<item name="animator" type="id">false</item>

我确定这些不是来 self 的值(value)观，其中大部分来自 com.android.datetimepicker.date.DatePickerDialog 类，我不知道如何解决这些问题来自图书馆而不是我的项目。

解决方法是:在 res/values 文件夹中创建一个名为 ids.xml 的文件并将此内容放入:

`<?xml version="1.0" encoding="utf-8"?>
<resources>
<item name="sos_key_shift_state" type="id"/>
<item name="cc_card" type="id" />
<item name="cc_ccv" type="id" />
<item name="cc_entry" type="id" />
<item name="cc_entry_internal" type="id" />
<item name="cc_exp" type="id" />
<item name="cc_form_layout" type="id" />
<item name="cc_four_digits" type="id" />
<item name="cc_zip" type="id" />
<item name="text_helper" type="id" />
</resources>`

这解决了我的问题...
