Android Studio cannot resolve symbol 'TabLayout'

標籤：

出現這個問題一般是因為未引用庫，解決方案如下：

1、在app/build.gradle下

 

dependencies {    compile fileTree(dir: ‘libs‘, include: [‘*.jar‘])    compile ‘com.android.support:appcompat-v7:your_api_version_number.0.0‘//相應版本    compile ‘com.android.support:design:+‘//相應版本}

 

然後Build->Clean Project 

2、在項目根build.gradle下

ext {    compileSdkVersion = 23    buildToolsVersion = "23.0.1"//相應版本    supportLibVersion = "23.0.1"//相應版本}

然後：工具列中sync project with gralde file
