错误信息 #

1. Failed to find style with 2131032999（找不到ID为2131032999的样式资源）
2. Style ResourceReference{namespace=apk/res-auto, type=attr, name=textAppearanceButton} is not of type STYLE (instead attr)（apk/res-auto命名空间下的textAppearanceButton属性被当作样式引用，但它实际是attr类型）
3. 空指针异常堆栈：

解决建议 #

1. 修正主题中textAppearanceButton的配置 #

错误核心是主题里把textAppearanceButton指向了attr而非具体样式。打开styles.xml或themes.xml，找到当前应用主题，将错误的配置替换为Material Components的默认样式：

<style name="AppTheme" parent="Theme.MaterialComponents.DayNight.DarkActionBar">
    <!-- 错误示例：<item name="textAppearanceButton">?attr/someAttr</item> -->
    <item name="textAppearanceButton">@style/TextAppearance.MaterialComponents.Button</item>
</style>

2. 定位并修复缺失的样式资源 #

针对Failed to find style with 2131032999错误：

• 通过Android Studio的Find in Path功能搜索2131032999，找到对应的资源名称；
• 确认该样式是否被误删，或是依赖库未正确引入；
• 检查Material Components库与AndroidX版本是否兼容，尝试升级或降级到匹配版本（比如使用com.google.android.material:material:1.9.0）。

3. 清理缓存并重建项目 #

• 菜单栏选择File > Invalidate Caches...，点击Invalidate and Restart重启Studio；
• 执行Build > Clean Project，再执行Build > Rebuild Project；
• 点击工具栏的Sync Project with Gradle Files同步配置。

4. 检查TabLayout布局代码 #

确保布局中TabLayout的样式引用正确，避免错误的属性赋值：

<com.google.android.material.tabs.TabLayout
    android:id="@+id/tabLayout"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:tabTextAppearance="@style/TextAppearance.MaterialComponents.Tab"
    app:tabIndicatorColor="@color/design_default_color_primary" />
