Android---WebView设定支持缩放

对WebView和WebSettings做一下设定

webview.setVerticalScrollbarOverlay(true); //指定的垂直滚动条有叠加样式

WebSettings settings = webview.getSettings();

settings.setUseWideViewPort(true);//设定支持viewport

settings.setLoadWithOverviewMode(true);

settings.setBuiltInZoomControls(true);

settings.setSupportZoom(true);//设定支持缩放   

html界面meta标签

<metaname="viewport"content="height= [pixel_value| "device-height"] ,width= [pixel_value| "device-width"] ,initial-scale=float_value,//初始缩放minimum-scale=float_value,//最小maximum-scale=float_value,//最大user-scalable= ["yes" | "no"]//是否允许用户对页面缩放          "/>

例如：<meta name="viewport" content="width=device-width,user-scalable=yes  initial-scale=1.0, maximum-scale=2.0">-->设定支持缩放，最大两倍缩放
