1.3 翻页、滚动及滚动条样式

1. 包括快速向上、向下翻页

/**

• Scrolls the contents of this WebView down by half the page size.
• @param bottom true to jump to bottom of page
• @return true if the page was scrolled
  **/
  mWebView. pageDown(boolean bottom)

/**

• Scrolls the contents of this WebView up by half the view size.
• @param top true to jump to the top of the page
• @return true if the page was scrolled
  /
  mWebView. pageUp(boolean top)
  //滚动：
  mWebview.getView().scrollTo(x,y)
  /
• 设置滚动条样式
  */
  //竖直快速滑块，设置null可去除
  mWebview.getX5WebViewExtension().setVerticalTrackDrawable (Drawable drawable)
  //判断水平滚动条是否启动
  mWebview.getX5WebViewExtension().isHorizontalScrollBarEnabled ()
  //启用或禁用水平滚动条
  mWebview.getX5WebViewExtension().setHorizontalScrollBarEnabled (boolean enabled)
  //判断竖直滚动条是否启动
  mWebview.getX5WebViewExtension().isVerticalScrollBarEnabled ()
  //启用或禁用竖直滚动条
  mWebview.getX5WebViewExtension().setVerticalScrollBarEnabled (boolean enabled)
  //设置滚动条渐隐消失的时间段
  mWebview.getX5WebViewExtension().setScrollBarFadeDuration(int duration)
  //设置滚动条多久开始渐隐消失
  mWebview.getX5WebViewExtension().setScrollBarDefaultDelayBeforeFade (int delay)
