如何解决无法在导航视图中使用颜色状态列表 Android kotlin
我有两个项目，一个是在 NavigationView 中使用颜色状态列表选择器在不同交互状态下更改 Navigation Drawer 中项目的背景颜色。
<com.google.android.material.navigation.NavigationView
android:id="@+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:fitsSystemWindows="true"
app:itemBackground="@color/nav_bgstate_list" <------
app:itemIconTint="@color/nav_state_list" <------
app:itemTextColor="@color/nav_state_list" <------
app:headerLayout="@layout/nav_header_main"
app:menu="@menu/activity_main_drawer" />
These three lines causes error but when I remove them,it works fine.
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- Item checked -->
<item android:color="@color/brand" android:state_checked="true" />
<!-- Item pressed -->
<item android:color="@color/black" android:state_pressed="true" />
<!-- Item default -->
<item android:color="@color/brand70" />
</selector>
我将相同的代码复制到另一个项目中，但它开始抛出一堆错误。日志如下

我检查了 minSdk 版本、编译后的 sdk 版本、主题、gradle 版本、与其版本的依赖关系等，一切都一样，没有什么不同。我知道我应该使用可绘制状态而不是颜色状态，但我不明白为什么它在其他项目中工作，而在另一个项目中工作。

我发现崩溃是因为我使用颜色状态选择器设置了 itembackground。 itemIconTint 和 itemTextColor 适用于颜色状态选择器。每当我尝试在那里设置状态选择器时，只有 itemBackground 崩溃，所以我找到了一个提到 here 的解决方案，基本上我需要添加已检查的 android:checkable="true" 但即使在添加它之后它也崩溃了。我不知道为什么。

所以我意识到颜色状态选择器适用于较新版本的 android > 10，但不适用于旧版本的 android。
