我想将包含CSS样式表的HTML页面发送到电子邮件帐户.问题是CSS样式表根本不可见.我是否必须内联每个CSS样式？这似乎是非常低效的方法.还有其他想法吗？
以下是发送电子邮件的PHP代码:
<?php
$to = "myaccount@gmail.com";
// subject
$subject = "Test mail";
// message
$message = file_get_contents("index.html");
// from
$from = "myaccount@gmail.com";
// To send HTML mail, the Content-type header must be set
$headers = 'MIME-Version: 1.0' . "\r\n";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
// Additional headers
$headers .= "From:" . $from;
// Mail it
mail($to,$subject,$message,$headers);
echo "Mail Sent.";
?>
非常感谢你的帮助.提前致谢.
I'm getting this error when I receive only one single item in a list. I'm using Jersey in the server side REST Web service, I only get the error when the List returned one single element and when it has 0 elements I get java.lang.NullPointerException But when it has more than one it works perfectly, and this is how I'm doing it :
@GET
@Path("getproject")
@Produces(MediaType.APPLICATION_JSON)
public List<Project> getPagedProjects(
@QueryParam("offset") int offset,
@QueryParam("limit") int limit,
@QueryParam("searchKey") String searchKey) throws Exception …我正在尝试在listView为空时设置空视图.这是我的完整XML布局:

我将图像转换为字节数组,如下所示:
public static byte[] convertToByteArray(String path) {
byte[] imageInByte = null;
try{
BufferedImage originalImage =
ImageIO.read(new File(path));
ByteArrayOutputStream baos = new ByteArrayOutputStream();
ImageIO.write( originalImage, "png", baos );
baos.flush();
imageInByte = baos.toByteArray();
baos.close();
}catch(IOException e){
System.out.println(e.getMessage());
}
return imageInByte; …我想将"icon"的字符串转换为字节数组,然后将其转换为Bitmap.问题是模拟器中的图像没有显示.我想我做得不对,但我知道为什么.非常感谢你的帮助.提前致谢

我这样做了,但它不起作用:
// convert String to byte[]
String stringToConvert = project.getIcon();
byte[] theByteArray = stringToConvert.getBytes();
// convert Byte[] to Bitmap
Bitmap bm = BitmapFactory.decodeByteArray(theByteArray,
0, theByteArray.length);
DisplayMetrics dm = new DisplayMetrics();
holder.imageIcon.setMinimumHeight(dm.heightPixels);
holder.imageIcon.setMinimumWidth(dm.widthPixels);
holder.imageIcon.setImageBitmap(bm);
