有关安卓webview模式下拉刷新只能拉一半（盖住提示文本）问题解决

类似这个问题http://ask.dcloud.net.cn/question/27036
方法就是在根页面创建子webview的时候要隐藏的子webview延时10ms隐藏就可以了

        <nav class="mui-bar mui-bar-tab">  
            <a id="defaultTab" class="mui-tab-item mui-active" href="first_index.html">  
                <span class="mui-icon iconfont icon-home"></span>  
                <span class="mui-tab-label">首页</span>  
            </a>  
            <a class="mui-tab-item" href="circle_index.html">  
                <span class="mui-icon iconfont icon-circle"></span>  
                <span class="mui-tab-label">圈</span>  
            </a>  
            <a class="mui-tab-item" href="user_index.html">  
                <span class="mui-icon iconfont icon-shouye"></span>  
                <span class="mui-tab-label">我</span>
