android中svg文件的使用

时间:2022-11-20 18:04:57

一些矢量图在android中无法进行展示,这时我们需要通过哦其他的提劲进行处理。

如在资源文件中放入html,使用html对矢量图进行包装,,在应用页面使用webview进行引入。


<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">


<META HTTP-EQUIV="imagetoolbar" CONTENT="no">
<style type="text/css">
body { font-family: "Verdana", "Arial", "Helvetica", "sans-serif"; font-size: 12px; line-height: 180%; }


</style>
<SCRIPT language=JavaScript>
drag = 0
move = 0


var ie=document.all;
var nn6=document.getElementById&&!document.all;
var isdrag=false;
var y,x;
var oDragObj;


function moveMouse(e) {
 if (isdrag) {
 oDragObj.style.top  =  (nn6 ? nTY + e.clientY - y : nTY + event.clientY - y)+"px";
 oDragObj.style.left  =  (nn6 ? nTX + e.clientX - x : nTX + event.clientX - x)+"px";
 return false;
 }
}


function initDrag(e) {
 var oDragHandle = nn6 ? e.target : event.srcElement;
 var topElement = "HTML";
 while (oDragHandle.tagName != topElement && oDragHandle.className != "dragAble") {
 oDragHandle = nn6 ? oDragHandle.parentNode : oDragHandle.parentElement;
 }
 if (oDragHandle.className=="dragAble") {
 isdrag = true;
 oDragObj = oDragHandle;
 nTY = parseInt(oDragObj.style.top+0);
 y = nn6 ? e.clientY : event.clientY;
 nTX = parseInt(oDragObj.style.left+0);
 x = nn6 ? e.clientX : event.clientX;
 document.onmousemove=moveMouse;
 return false;
 }
}
document.onmousedown=initDrag;
document.onmouseup=new Function("isdrag=false");


</SCRIPT>
<script language="JavaScript" type="text/JavaScript">


  var   count   =   10;  
  function   Picture()  
  {  
  count   =   Counting(count);  
  Resize(count);  
  return   false;  
  }  
  function   Counting(count){  
  if (event.wheelDelta   >=   120)  {
if(count<21){count++;}
  }
  else if(event.wheelDelta   <=   -120) {
if(count>4){count--;}
  }
  return   count;  
  }  
  function   Resize(count){  
  oImage.style.zoom   =   count   +   '0%';  
  }  


</script>


</head>
<body style="overflow-y:hidden;overflow-x:hidden;">


<div id='block1' onmouseout='drag=0' onmouseover='dragObj=block1; drag=1;' style='z-index:10; height: 0; width: 0; position: absolute; top: 0px;left: 0px; ' class="dragAble"> 
<img id="oImage" name='images1' src='roadgrid.svg' border='0' style="cursor:crosshair;"  onmousewheel="Picture()">
</div>
</body>
</html>


android代码如下:

area_road_network_web_view.loadUrl("file:///android_asset/www/luwang.html");
