这是我的v31/values-v31

当我尝试构建这个项目时。我经常收到这个错误（

错误：C:\Users\Dell.gradle\caches\transforms-2\files-2.1\66e9dd10963e7a2704a4a2116f19e6fb\material-1.5.0-alpha03\res\values-v31\values-v31.xml:3:5- 94：AAPT：错误：资源 android:color/system_neutral1_1000 未找到。）

我尝试过的解决方案重建项目，清理项目，使缓存无效并重新启动，enter code here 并删除并重新创建该模拟器，但对我没有任何效果

标签： android kotlin android-recyclerview material-components-android multiview

【解决方案1】：

如release notes中所述：

1.5.0-alpha03 版本引入了新的Material 3 themes 和

使用此版本的库时，请务必将您应用的 compileSdkVersion 更新为 31。

【讨论】：

【解决方案2】：

简答：

要修复编译错误，请确保在使用时将应用的 compileSdkVersion 更新为 31 新版本的材料组件库。

或者，您可以将 Material Components 库降级为 1.4.0 或 1.5.0-alpha02。

说明：

从版本 1.5.0-alpha03 开始，材料组件库需要编译 SDK 版本 31（在提交 40509dc 时提出）。
见release notes on GitHub。

这是必需的，因为新的 Material 3 themes 支持 dynamic colors。
从 Android S (API 31) 开始，该框架能够根据用户在设备上的壁纸或颜色选择在您的 UI 中支持动态颜色。

阅读更多关于“Material You”壁纸主题系统“Monet”的信息，该系统是该功能的基础：

【讨论】：

这是正确答案

【解决方案3】：

问题出在下面一行：

implementation 'com.google.android.material:material:1.5.0-alpha03'

我使用了这个并且得到了同样的错误。用以下行替换它可以解决问题：

implementation 'com.google.android.material:material:1.5.0-alpha02')

【讨论】：

这似乎也为我解决了；谢谢。
不，这不是真正的解决方案。
但这是降级依赖...

【解决方案4】：

我遇到了这个错误，它已经解决了。更改或降级您的依赖项应该可以解决此问题。如果您在此link 中遇到此错误，我建议您应该同时更改这两个，来自：

implementation 'androidx.appcompat:appcompat:1.4.0'
implementation 'com.google.android.material:material:1.5.0'

到：

implementation 'androidx.appcompat:appcompat:1.3.0'
implementation 'com.google.android.material:material:1.4.0'

然后，再次运行您的应用程序。我认为这种方法有效。如果您创建新项目，但在尝试运行应用时没有注意到此错误，通常会发生这种情况。

【讨论】：

谢谢，成功了。
解决了我的问题

【解决方案5】：

在 Java 项目中尝试以 API 30 为目标时，我也遇到了这个错误。我曾尝试仅降级 appcompat 依赖项，并收到此错误。事实证明，您还需要关闭 material 依赖项。

要针对 API 30，您需要将 androidx.appcompat:appcompat 和 com.google.android.material:material 都降级到旧版本。

从以下位置更改版本：

implementation 'androidx.appcompat:appcompat:1.4.1'
implementation 'com.google.android.material:material:1.5.0'

收件人：

implementation 'androidx.appcompat:appcompat:1.3.1'
implementation 'com.google.android.material:material:1.4.0'
