Question

我尝试使用RecyclerView版本24.2.1进行编译，但我总是遇到build.gradle错误无法解决：com.android.support:RecyclerView- ... 。我也试过不同的版本，但总是有同样的失败。

我的build.gradle有以下形式：

android {
  compileSdkVersion 24
  buildToolsVersion "24.0.1"
  .....
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-v7:24.2.1'
  compile 'com.android.support:design:24.2.1'
  compile 'com.android.support:cardview-v7:24.2.1'
  compile 'com.android.support:RecyclerView-v7:24.2.1'
  compile 'org.greenrobot:eventbus:3.0.0'
  compile 'org.nanohttpd:nanohttpd:2.2.0'
  testCompile 'junit:junit:4.12'
}

通过我安装的SDK-Manager：

Android SDK工具25.2.5
Android SDK Platform-tools 25.0.3
Android SDK Build-tools 24.0.1
API 25
API 24
Android支持存储库第42版
Google Repository Rev 42

我该如何解决这个失败？提前致谢
