android - NoSuchMethodError : No virtual method removeOnPageChangeListener 错误

Question

我正在使用 ongakuer/CircleIndicator用于添加 viewpager 指标的库。除了更改一个小的 code 之外，我按原样使用了示例代码。从 customViewpager.addOnPageChangeListener 到 customViewpager.setOnPageChangeListener 因为它显示编译错误。之后没有编译错误。

当我运行该 Activity 时，我立即收到以下错误:

java.lang.NoSuchMethodError: No virtual method removeOnPageChangeListener(Landroid/support/v4/view/ViewPager$OnPageChangeListener;)V in class Landroid/support/v4/view/ViewPager; or its super classes (declaration of 'android.support.v4.view.ViewPager' appears in /data/app/com.app.app-2/base.apk)

遇到与 RecyclerView.Adapter 类似的问题-

java.lang.NoSuchMethodError: No virtual method setAdapterCount ...

使缓存无效然后重新启动 Android Studio 解决了我的错误。 You can find directions to invalidate caches in IntelliJ (the software Android Studio is built upon) at this link .
