代码示例来源：origin: yll2wcf/book

void webViewMethod() {
  webView.goBack();//后退
  webView.goForward();//前进
  //以当前的index为起始点前进或者后退到历史记录中指定的steps， 如果steps为负数则为后退，正数则为前进
  // webView.goBackOrForward(intsteps);
  webView.canGoForward();//判断是否可以前进
  webView.canGoBack(); //判断是否可以后退
  webView.clearCache(true);//清除网页访问留下的缓存，由于内核缓存是全局的因此这个方法不仅仅针对webview而是针对整个应用程序.
  webView.clearHistory();//清除当前webview访问的历史记录，只会webview访问历史记录里的所有记录除了当前访问记录.
  webView.clearFormData();//这个api仅仅清除自动完成填充的表单数据，并不会清除WebView存储到本地的数据。
  webView.onResume(); //激活WebView为活跃状态，能正常执行网页的响应
  webView.onPause();//当页面被失去焦点被切换到后台不可见状态，需要执行onPause动过， onPause动作通知内核暂停所有的动作，比如DOM的解析、plugin的执行、JavaScript执行。
  webView.pauseTimers();//当应用程序被切换到后台我们使用了webview， 这个方法不仅仅针对当前的webview而是全局的全应用程序的webview，它会暂停所有webview的layout，parsing，javascripttimer。降低CPU功耗。
  webView.resumeTimers();//恢复pauseTimers时的动作。
  webView.destroy();//销毁，关闭了Activity时，音乐或视频，还在播放。就必须销毁
}
//按键事件
