检索项目的父项时出错：找不到与给定名称相匹配的资源 'android:Widget.Material.Spinner.Underlined'

Question

我是初学者我想制作一个使用 compileSdkVersion 17 的项目但是当运行 project 在上面给我这个错误这是我 gradle

的代码

android {
compileSdkVersion 17
buildToolsVersion '25.0.0'
 defaultConfig {
    applicationId "com.sadeem.vl2player"
    minSdkVersion 14
    targetSdkVersion 26
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}



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

androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
    exclude group: 'com.android.support', module: 'support-annotations'
})
compile 'com.android.support:appcompat-v7:26.+'
compile 'com.android.support.constraint:constraint-layout:1.0.2'
testCompile 'junit:junit:4.12'

}

Answer 1

因为您使用的是支持库 v26

compile 'com.android.support:appcompat-v7:26.+'

你必须使用

compileSdkVersion 26
