这是我的v31/values-v31

在尝试构建这个项目时，我经常会遇到这个错误（

ERROR: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: error: resource android:color/system_neutral1_1000 not found.)

我尝试的解决方案有重新构建项目、清除项目、使缓存无效并重启、输入代码以及删除并重新创建模拟器，但都没有起作用。

Answer 1

如在发布说明中所述：

版本1.5.0-alpha03引入了新的Material 3主题，并且

使用该库的这个版本时，请确保将应用程序的compileSdkVersion更新至31。

- Gabriele Mariotti

Answer 2

简短回答：

如果使用最新版本的Material Components library，为了解决编译错误，请确保将您的应用程序的compileSdkVersion更新为31。

或者您可以将Material Components library降级为1.4.0或1.5.0-alpha02。

解释：

从版本1.5.0-alpha03开始，Material Components library需要compile SDK版本31（在提交40509dc 时提高）。
请参见GitHub上的发布说明。

这是因为新的Material 3主题支持动态颜色。
从Android S（API 31）开始，框架提供了根据用户壁纸或设备上的颜色选择支持UI中的动态颜色的能力。

关于基于壁纸的主题化系统“Monet”和这项功能的更多信息，请参阅以下链接：

这是正确的答案。 - Sadique Khan

这并没有帮助。 - AlexS

Answer 3

问题出现在以下一行：

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

我使用了这个并且得到了相同的错误。用以下行替换它解决了这个问题：

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

- Omur Gun

那似乎也解决了我的问题；谢谢你。 - Edward Falk

不，这不是真正的解决方案。 - Gabriele Mariotti

但这会降级一个依赖项... - Fran Marzoa

Answer 4

我遇到了这个错误，并且已经解决了。更改或降级你的依赖项应该可以解决这个问题。如果你从这个链接遇到了这个错误，我建议你应该同时更改这两个依赖项，从：

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

收件人：

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

然后，再次运行你的应用程序。我认为这种方法有效。如果你创建了新项目但没有注意到此错误，在尝试运行应用程序时通常会发生这种情况。

- Mr Alexander Ws

谢谢，它起作用了。 - Atif AbbAsi

解决了我的问题。 - FreddicMatters

Answer 5

我也遇到了这个错误，当我试图在一个Java项目中针对API 30时。我曾尝试只降级 appcompat 依赖项并得到了这些错误。结果是你需要同时降级 material 依赖项。

要针对 API 30，你需要将 androidx.appcompat:appcompat 和 com.google.android.material:material 两者都降级到较旧的版本。

将版本从：

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'

- Paul Smith

Answer 6

我不确定这是否是解决方案（对我有效），但将 compileSdk 和 targerSdk 更新到31 并更新这些库解决了我的错误：

implementation 'androidx.core:core-ktx:1.7.0'
implementation 'androidx.constraintlayout:constraintlayout:2.1.3'
implementation 'com.google.android.material:material:1.5.0'

- BMU

Answer 7

请按照以下步骤操作：

在 build.gradle（模块）中

        apply plugin: 'com.android.application'
        apply plugin: 'com.google.gms.google-services'
        
        
        android {
            compileSdkVersion 30
            buildToolsVersion '30.0.2'
        
            defaultConfig {
                applicationId "your package name"
                minSdkVersion 21
                targetSdkVersion 30
                versionCode 1
                versionName "1.0"
        
                testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
            }
        
            buildTypes {
                release {
                    minifyEnabled false
                    proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
                }
            }
            compileOptions {
                sourceCompatibility JavaVersion.VERSION_1_8
                targetCompatibility JavaVersion.VERSION_1_8
            }
        
        }
        
        dependencies {
        
            implementation fileTree(dir: 'libs', include: ['*.jar'])
            implementation 'androidx.appcompat:appcompat:1.3.0'
            implementation 'com.google.android.material:material:1.4.0'
            implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
            testImplementation 'junit:junit:4.12'
            androidTestImplementation 'androidx.test.ext:junit:1.1.1'
            androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
        }
    
    

在 build.gradle (project) 中 输入代码

    // Top-level build file where you can add configuration options common to all sub-projects/modules.
    buildscript {
        repositories {
            google()
            jcenter()
        }
        dependencies {
