错误：未找到资源样式/Animation.AppCompat.Dialog（又名com.example.myapplication:style/Animation.AppCompat.Dialog）

Question

我是Android的新手，正在尝试使用Android Studio 3.3.2版本开发Hello应用程序。我正在尝试创建默认导航活动项目，但在构建过程中出现如下错误。

我有一个像下面这样的项目 gradle 文件：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.example.myapplication"
        minSdkVersion 15
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support:design:28.0.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}

我能够导入并运行其他项目，但这个项目却出现了上述错误。

你能看一下这篇帖子并检查一下是否相关吗：https://dev59.com/sVUM5IYBdhLWcg3wMeAk - Hermueller

请添加以下代码到res/values/styles.xml文件中： - YuvrajsinhJadeja

Answer 1

AppCompat是一个库项目。您需要在Android项目中引用该库项目。

1. 在项目的build.gradle文件中包含Google的Maven仓库

   allprojects { repositories { google() 如果您使用低于4.1版本的Gradle，您必须 使用以下内容： maven { url 'https://maven.google.com' } } }

2. 对于每个要使用Support Library的模块，请将库添加到模块的build.gradle文件的dependencies块中。例如，要添加v7核心工具库，请添加以下内容：

implementation "com.android.support:support-core-utils:28.0.0"

Answer 2

试试这个

文件->导入 (android-sdk\extras\android\support\v7)。选择 "AppCompat" 项目->属性->Android。在库部分添加并选择 "AppCompat"

如果上述方法不起作用，请尝试以下另一种选项

首先检查您是否正在使用 Androidx，然后执行以下操作

移除

implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support:design:28.0.0'

添加这个

implementation 'androidx.appcompat:appcompat:1.0.2'
implementation 'com.google.android.material:material:1.1.0-alpha08'

请检查您的gradle.properties文件，确保已添加以下两行代码，如果未添加，请添加：

android.useAndroidX=true
android.enableJetifier=true

然后一次清理和重建项目。
