gradle文件中的“com.android.support:appcompat-v7.27.1.1”问题

这是我的依赖项文件,在编译“ com.android.support:appcompat-v7.27.1.1”上有带下划线的红色文本.

apply plugin: 'com.android.application'
 android {
compileSdkVersion 27
defaultConfig {
    applicationId "com.abc.mcaproject"
    minSdkVersion 21
    targetSdkVersion 27
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
}

dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])


compile 'com.android.support:appcompat-v7.27.1.1'
implementation 'com.android.support.constraint:constraint-layout:1.1.0'
implementation 'com.google.firebase:firebase-database:11.6.0'
implementation 'com.google.firebase:firebase-messaging:11.6.0'
implementation 'com.google.firebase:firebase-auth:11.6.0'
implementation 'com.google.firebase:firebase-storage:11.6.0'
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'
}

apply plugin: 'com.google.gms.google-services'

因此,我在更改styles.xml中的主题时遇到问题

最佳答案
当您将鼠标悬停在红线上时,可能会向您显示以下图像,我将其附加在下面.Click to see the image

它告诉您的是某些库中存在版本冲突,因此建议我们添加这些库.对于我来说,首先显示为CardView,然后显示为Design.所以我加了.下面是它的代码.

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:27.1.1'
    implementation 'com.android.support.constraint:constraint-layout:1.1.0'
    implementation 'com.payumoney.sdkui:plug-n-play:1.2.0'
    implementation 'com.android.support:cardview-v7:27.1.1'
    implementation 'com.android.support:design:27.1.1'

    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'
}

因此,请将其添加为2或更多.
希望能有所帮助.
