底部tab切换闪烁问题

mui.init();

        var index = 0;            
        var subviews = ["adviserHtml/index.html","interactiveHtml/index.html","interactiveHtml/chat.html","NewsHtml/index.html","MyCenterHtml/index.html"];  

        mui.plusReady(function () {  
            var self = plus.webview.currentWebview();  

            for(var i = 0; i<4; i++){  
                var subwebview = plus.webview.create(subviews[i],subviews[i],{  
                    "top":0,  
                    "bottom":"57px"  
                });  
                if(i!==0){  
                    subwebview.hide();  
                }  

                self.append(subwebview);  
            }  

            var activeTab = subviews[index];  

            mui("#bar").on("tap","a.mui-tab-item",function(e){  

                var currentLink = this.getAttribute("href");  
                if(currentLink == activeTab){                         
                    return;  
                }                     
                plus.webview.show(currentLink);  
                plus.webview.hide(activeTab);                     
                activeTab = currentLink;  
            });  

        });  

按照教程，做的底部切换效果。
在第一次切换的时候，页面会发生闪烁。
后面再点击则不会， 求解。
