沒有捷徑可以這樣做。你需要通過代碼來完成。

public static InputStream getInputStream(String url) 
{ 
    InputStream inputStream = null; 
    HttpConnection httpConnection = null; 
    try 
    {       
     httpConnection = (HttpConnection)Connector.open(url+connectiontype)); 
     httpConnection.setRequestMethod(HttpConnection.POST); 
     final int r=httpConnection.getResponseCode(); 
     if(r==200) 
      inputStream = httpConnection.openDataInputStream(); 
    } 
    catch(final Exception e) 
    { 
     System.out.println("Error is "+e.getMessage()); 
    } 
    return inputStream; 
}

，並使用getInputStream()這樣的：

InputStream is=getInputStream(s1); 
int length=is.available(); 
//System.out.print("length ==========="+length);   
byte[] data=new byte[length]; 

data = IOUtilities.streamToBytes(is); 

// code to save image in sd card 
saveFile.create(); 
OutputStream outStream = saveFile.openOutputStream(); 
outStream.write(data); 
outStream.close(); 
saveFile.close(); 
is.close();

此代碼將保存從URL的形象。
