使用此方法并传递下载URL。
private Image getImage(String url) throws IOException
{
ContentConnection connection = (ContentConnection) Connector.open(url);
DataInputStream iStrm = connection.openDataInputStream();
ByteArrayOutputStream bStrm = null;
Image im = null;
try
{
byte imageData[];
int length = (int) connection.getLength();
if (length != -1)
{
imageData = new byte[length];
iStrm.readFully(imageData);
} else {
bStrm = new ByteArrayOutputStream();
int ch;
while ((ch = iStrm.read()) != -1)
bStrm.write(ch);
imageData = bStrm.toByteArray();
bStrm.close();
}
im = Image.createImage(imageData, 0, imageData.length);
}
finally
{
// Clean up
if (iStrm != null)
iStrm.close();
if (connection != null)
connection.close();
if (bStrm != null)
bStrm.close();
}
return (im == null ? null : im);
}
