BottomNavigationView 上的错误膨胀类和此组件上的样式要求您的应用程序主题为 Theme.AppCompat

Question

我遇到两个错误，可能与我的MainActivity 中的BottomNavigationView 有关。这只发生在部分用户而不是所有用户身上。

Fatal Exception: java.lang.RuntimeException: Unable to start activity ComponentInfo{com.MyProject.MainActivity}: android.view.InflateException: Binary XML file line #41 in com.MyProject:layout/activity_main: Binary XML file line #41 in com.MyProject:layout/activity_main: Error inflating class com.google.android.material.bottomnavigation.BottomNavigationView

这是我的BottomNavigationView 详细信息：

    <com.google.android.material.bottomnavigation.BottomNavigationView
        android:id="@+id/bottom_navigation_view"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginStart="0dp"
        android:layout_marginEnd="0dp"
        android:background="@color/nav_bar"
        app:labelVisibilityMode="labeled"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:menu="@menu/navigation"
        app:itemIconTint="@drawable/bottom_nav_colours"
        app:itemTextColor="@drawable/bottom_nav_colours" />

错误中的第 41 行指向app:itemTextColor。这是我为@drawable/bottom_nav_colours 绘制的。

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_checked="true"
        android:color="@color/black"/>
    <item android:color="@color/grey"/>
</selector>

我的应用程序主题继承自 "Theme.MaterialComponents.Light.NoActionBar.Bridge"。

首先，我的bottom_nav_colours 位于drawable 文件夹中，对于某些用户来说它会崩溃。尝试在现有的 drawable-any-dpi-v24 文件夹中复制它，但它仍然崩溃。

不知道在这里做什么。我认为问题与BottomNavigationView 中的app:itemTextColor 有关。

尝试在底部导航视图中添加主题。它在 TabsLayout 上对我有用 - android:theme="@style/Theme.MaterialComponents"

com.google.android.material.tabs.TabLayout
    android:id="@+id/tabLayout"
    style="@style/MyCustomTabLayout"
    android:theme="@style/Theme.MaterialComponents"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:visibility="visible"
