BottomNavigationView 膨胀错误。资源 $NotFoundException：资源 ID #0x0
BottomNavigationView inflating error. Resources$NotFoundException: Resource ID #0x0
我在使用设计支持库中的 BottomNavigationView 时遇到一些问题。
我在 activity_main.xml:
中使用它
<android.support.design.widget.BottomNavigationView
android:id="@+id/navigation"
app:itemIconSize="16dp"
app:labelVisibilityMode="labeled"
app:itemTextColor="@color/white"
app:itemIconTint="@color/white"
app:itemBackground="@color/medium_purple"
app:menu="@menu/main"
android:layout_alignParentBottom="true"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
应用程序在给 xml 充气时崩溃。异常的完整堆栈跟踪如下：

所有支持库版本和compileSdk版本相同。我真的不明白那是什么鬼。有人可以解释一下吗？
谢谢
问题在你的问题标题中
Caused by: android.content.res.Resources$NotFoundException: Resource ID #0x0
这意味着您正在使用不存在的资源。我不知道它是哪个，但这是你将如何修复。转到文件 @menu/main 并删除图标的所有属性。你可以留下文字。一个一个添加，看看是哪一个出了问题。很可能是您的图标被错误地放置在文件夹 drawable-24 而不是 drawable 或比您正在测试的文件夹更高的 android API 文件夹中。有时我们会犯这些错误。
另请注意，某些属性仅适用于从某个 android API 开始。考虑检查以 app.
开头的属性
app:itemTextColor="@color/white"
app:itemIconTint="@color/white"
app:itemBackground="@color/medium_purple"
我遇到了这个问题，它困扰了我一天左右。基本上，BottomNav 需要在您的主题中为 textColorSecondary 定义的颜色状态列表，而不是纯色。所以我从：
<style name="MTheme" parent="Theme.MaterialComponents.Light.Bridge">
...
<item name="android:textColorSecondary">#295055</item>
到
<style name="MTheme" parent="Theme.MaterialComponents.Light.Bridge">
...
<item name="android:textColorSecondary">@color/secondary_textcolor</item>
其中 secondary_textcolor 等于
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_enabled="true" android:color="#295055"/>
<item android:state_enabled="false" android:color="@color/disabled"/>
</selector>
我浪费了很多时间来添加和删除依赖项来寻找这个解决方案。
