使用腾讯内核 implementation 'com.tencent.tbs.tbssdk:sdk:43903'

。使用x5内核的webview，我这里自定义了一个

}

，最后使用

url="https://view.officeapps.live.com/op/view.aspx?src="+url;

wwebview.loadUrl(url);

我的使用dialog的

  try {AlertDialog.Builder alterDiaglog = new AlertDialog.Builder(context);alterDiaglog.setIcon(R.mipmap.ispm);//图标MyX5WebView wb_view= (MyX5WebView) LayoutInflater.from(context).inflate(R.layout.item_webview,null);url="https://view.officeapps.live.com/op/view.aspx?src="+url;// webview必须设置支持Javascript才可打开wb_view.getSettings().setJavaScriptEnabled(true);// 设置此属性,可任意比例缩放wb_view.getSettings().setUseWideViewPort(true);wb_view.loadUrl(url);//通过在线预览office文档的地址加载alterDiaglog.setView(wb_view);
//            alterDiaglog.setView(remotePDFViewPager);alterDiaglog.show();} catch (Exception e) {e.printStackTrace();}

https://view.officeapps.live.com/op/view.aspx?src=这个前缀好像只是展示docx 其他文件浏览服务器去找，谷歌肯定是不能用了
