在Android中以精美的形式发送电子邮件

在本文中,我们将发送一封电子邮件,其中包含精心设计的表单以显示与邮件一起发送的数据。
众所周知,对我们所有人来说,使用电子邮件已经变得十分必要和重要。有各种电子邮件服务提供商,例如Yahoo,Outlook,iCloud和Gmail等。这些技术巨头为每个用户提供免费的电子邮件服务。如果您使用互联网,则无法忽略它,因为每当您访问任何网站/应用程序以在线购买/销售产品时,都可以。首先,您必须在这些网站/应用程序上注册才能证明您在现实世界中的身份。
在本文中,我们将学习如何使用JavaMail API将Gmail收件箱中的电子邮件发送到指定的电子邮件地址。我们将发送常见的用户数据,例如用户名,电子邮件地址,手机号码。等等
因此,让我们开始吧。
步骤1
- 首先,创建空的android项目,并在根目录中创建名称为MailSender.java和JSSEProvider.java的Java类。
- 现在,我们需要将Java Mail API jar文件导入到我们的项目中。从此处下载jar文件,解压缩并将其粘贴到libs文件夹中。
- 如果您的项目无法识别您的库,请重新启动Android Studio。
- 右键单击app-> New-> Folder-> Assets Folder,创建资产文件夹。我们将HTML文件放在此处,以在Gmail上显示数据。
- 要发送电子邮件,您的应用将需要互联网连接,因此请在AndroidManifest.xml文件中声明此权限。
<uses-permission android:name="android.permission.INTERNET"/>
第2步
- 在MailSender.java类中创建一些实例变量
// change this host name accordingly
private String mailhost = "webmail.xyz.in";
private String user;
private String password;
private Session session;
Context context;
private Multipart _multipart = new MimeMultipart();
- 现在,在MailSender.java文件中创建静态块以调用JSSEProvider.java类。JSSEProvider用于链接SSLContext,X509的KeyManagerFactory,X509的TrustManagerFactory和AndroidCAstore的修改版本。
static {
Security.addProvider(new JSSEProvider());
}
- 创建参数化的构造函数(传递上下文,“发件人电子邮件ID”和“密码”等)以初始化实例变量,并创建Properties类的对象以在构造函数内设置属性。在其中传递上下文,用户电子邮件ID和密码。看一下构造函数代码。
public MailSender(Context context,String user, String password) {
this.user = user;
this.password = password;
this.context = context;
Properties props = new Properties();
props.setProperty("mail.transport.protocol", "smtp");
props.setProperty("mail.host", mailhost);
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.port", "465");
props.put("mail.smtp.socketFactory.port", "465");
props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory");
props.put("mail.smtp.socketFactory.fallback", "false");
props.setProperty("mail.smtp.quitwait", "false");
session = Session.getDefaultInstance(props, this);
}
- 创建密码验证器方法以验证您的帐户。
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(user, password);
}
- 最后,创建用户定义的方法sendUserDetailWithImage()以将数据发送到邮件。下面的代码从assets文件夹中提取user_profile.html,将其转换为缓冲区,然后从缓冲区中读取它,最后将其转换为字符串对象,用实际的用户名替换关键字“ ”等等。请参阅完整的sendUserDetailWithImage()代码。
public synchronized void sendUserDetailWithImage(String subject, String body,
String sender, String recipients,String username,String email,String mobile,String dob,String age,String address,String profilePic ) throws Exception {
MimeMessage message = new MimeMessage(session);
DataHandler handler = new DataHandler(new ByteArrayDataSource(body.getBytes(), "text/plain"));
message.setFrom(new InternetAddress("no-reply@astromyntra.in"));
message.setSender(new InternetAddress(sender));
message.setSubject(subject);
message.setDataHandler(handler);
BodyPart messageBodyPart = new MimeBodyPart();
InputStream is = context.getAssets().open("user_profile.html");
int size = is.available();
byte[] buffer = new byte[size];
is.read(buffer);
is.close();
String str = new String(buffer);
str =str.replace("$$headermessage$$","You have got a new user.");
str=str.replace("$$username$$", username);
str=str.replace("$$email$$", email);
str=str.replace("$$mobile$$", mobile);
str=str.replace("$$dob$$",dob);
str=str.replace("$$age$$",age);
str=str.replace("$$address$$", address);
messageBodyPart.setContent(str,"text/html; charset=utf-8");
_multipart.addBodyPart(messageBodyPart);
// Put parts in message
message.setContent(_multipart);
if (recipients.indexOf(',') > 0)
message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(recipients));
else
message.setRecipient(Message.RecipientType.TO, new InternetAddress(recipients));
Transport.send(message);
}

第三步
要在表单中显示数据,请在assets文件夹内创建名为user_profile.html的HTML文件,然后粘贴以下代码。
