有关Android发送E-mail

传递信息的Action是Intent.ACTION_SEND。

代码如下：

Intent sendEmailIntent = new Intent(Intent.ACTION_SEND);

String subject = "subject ";
String body = "body ";
String[] extra = new String[] {"[e-mail]","[e-mail]","[e-mail]"};

sendEmailIntent .putExtra(Intent.EXTRA_EMAIL, extra[0]);//发送目标
sendEmailIntent .putExtra(Intent.EXTRA_CC, extra[1]); //抄送
sendEmailIntent .putExtra(Intent.EXTRA_BCC, extra[2]); //暗送
sendEmailIntent .putExtra(Intent.EXTRA_SUBJECT, subject);//标题
sendEmailIntent .putExtra(Intent.EXTRA_TEXT, body);//内容

sendEmailIntent .setType("text/plain");//指定内容是纯文本
//sendEmailIntent .setType("image/png");//指定内容是图片

startActivity(sendEmailIntent);
//也可自定义选择器
//startActivity(Intent.createChooser(sendEmailIntent, "请选择发送软件"));

Intent sendEmailIntent = new Intent(Intent.ACTION_SEND); String subject = "subject "; String body = "body "; String[] extra = new String[] {"[e-mail]","[e-mail]","[e-mail]"}; sendEmailIntent .putExtra(Intent.EXTRA_EMAIL, extra[0]);//发送目标 sendEmailIntent .putExtra(Intent.EXTRA_CC, extra[1]); //抄送 sendEmailIntent .putExtra(Intent.EXTRA_BCC, extra[2]); //暗送 sendEmailIntent .putExtra(Intent.EXTRA_SUBJECT, subject);//标题 sendEmailIntent .putExtra(Intent.EXTRA_TEXT, body);//内容 sendEmailIntent .setType("text/plain");//指定内容是纯文本 //sendEmailIntent .setType("image/png");//指定内容是图片 startActivity(sendEmailIntent); //也可自定义选择器 //startActivity(Intent.createChooser(sendEmailIntent, "请选择发送软件"));

写成方法：

private static void sendEmail(Context context, String[] to, String subject,
String body) {

Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);

if (to != null) {
email.putExtra(android.content.Intent.EXTRA_EMAIL, to);
}
if (subject != null) {
email.putExtra(android.content.Intent.EXTRA_SUBJECT, subject);
}
if (body != null) {
email.putExtra(android.content.Intent.EXTRA_TEXT, body);
}

email.setType("text/plain");

context.startActivity(Intent.createChooser(emailIntent , "请选择发送软件"));

}

private static void sendEmail(Context context, String[] to, String subject, String body) { Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND); if (to != null) { email.putExtra(android.content.Intent.EXTRA_EMAIL, to); } if (subject != null) { email.putExtra(android.content.Intent.EXTRA_SUBJECT, subject); } if (body != null) { email.putExtra(android.content.Intent.EXTRA_TEXT, body); } email.setType("text/plain"); context.startActivity(Intent.createChooser(emailIntent , "请选择发送软件")); }
