我有如下的项目 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'
}

我可以导入并运行另一个项目，但这会给我上面的错误。

Answer 1

AppCompat 是一个库项目。你需要在你的android项目中引用库项目

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

   所有项目{ 存储库{ 谷歌() 如果您使用的 Gradle 版本低于 4.1，则必须 而是使用: 行家{ 网址 ' https://maven.google.com ' } }

2. 对于要在其中使用支持库的每个模块，将库添加到模块的 build.gradle 文件的依赖项 block 中。例如，要添加 v7 core-utils 库，请添加以下内容:

实现“com.android.support:support-core-utils:28.0.0”
