//加载需要显示的网页

//获取Title

//调用js

String call = "javascript:方法名()";

wvShowProduce.loadUrl(call);

//js 调用android

wvShowProduce.addJavascriptInterface(new OCModel(), "OCModel");

 public class OCModel {
        //  分享到对话
        @JavascriptInterface
        public void ShareWithContent(String temp, final String data) {
}
