我正在将ViewPager添加到Android Studio中的应用程序中，但是当我尝试运行它时，它将抛出ClassNotFoundException重新分类为“ android.support.v4.view.ViewPager”。

做了大量的谷歌搜索，并尝试更改build.gradle中的依赖项，但没有任何改变可以改变我所看到的错误。

以下是Logcat的相关错误行：

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.android.playmusic/com.example.android.playmusic.MainActivity}: android.view.InflateException: Binary XML file line #60: Binary XML file line #60: Error inflating class android.support.v4.view.ViewPager
...

这是main_activity.xml布局：
