android – 如何正确扩展WebView？

我正在使用 Scroll webview horizontally inside a ViewPager的解决方案

它看起来非常有用,我在xml中引用了ExtendedWebView,

<ExtendedWebView
    android:id="@+id/webview"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
/>

.class中的实例ExtendedWebView,

LayoutInflater mInflater =  (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
layout  = mInflater.inflate(R.layout.lay1, null);
ExtendedWebView webView = (ExtendedWebView)layout.findViewById(R.id.webview);

但我得到’错误膨胀类ExtendedWebView’,所以任何人都可以帮助我给我一些想法,感谢您的时间和经验！

继承人是整个堆栈跟踪,

如果使用WebView而不是ExtendedWebView,我的代码工作正常:)

您需要提供该类的完整参考,包括包.

例如,

<org.example.myapp.ExtendedWebView
    android:id="@+id/webview"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
 />
