发送附件的六种方法：
第一种方法:
Uri uri = Uri.parse("mailto:sxh@oppo.com");
Intent it = new Intent(Intent.ACTION_SENDTO, uri);
startActivity(it);
第二种方法:
String[] toemail={"sxh@oppo.com", "mailtesst@163.com"};
String[] ccemail={"sxh@oppo.com", "mailtesst@163.com"};
String[] bccemail={"sxh@oppo.com", "mailtesst@163.com"};
Intent it = new Intent(Intent.ACTION_SEND);
it.putExtra(Intent.EXTRA_EMAIL, toemail);
it.putExtra(Intent.EXTRA_CC, ccemail);
it.putExtra(Intent.EXTRA_BCC, bccemail);
it.putExtra(Intent.EXTRA_SUBJECT, "I love you baby!");
it.putExtra(Intent.EXTRA_TEXT, "The email body text");
it.setType("text/plain");
startActivity(it);
startActivity(Intent.createChooser(it, "请选择Email客户端软件"));
第三种方法:
Intent it = new Intent(Intent.ACTION_SEND);
it.putExtra(Intent.EXTRA_EMAIL, "sxh@oppo.com");
it.putExtra(Intent.EXTRA_TEXT, "The email body text");
it.setType("text/plain");
startActivity(Intent.createChooser(it, "请选择Email客户端软件"));
第四种方法:
Intent it = new Intent(Intent.ACTION_SEND);
it.putExtra(Intent.EXTRA_EMAIL, "sxh@oppo.com");
it.putExtra(Intent.EXTRA_SUBJECT, "html test");
it.putExtra(Intent.EXTRA_TEXT, http://www.android100.org/);
it.setType("text/html");
startActivity(Intent.createChooser(it, "请选择Email客户端软件"));
第五种方法:
//实现多个附件的添加，这种方式不是标准的做法，没有标准的做法，所以第三方软件不会支持
Intent it = new Intent(Intent.ACTION_SEND);
it.putExtra(Intent.EXTRA_SUBJECT, "The email subject text");
//添加格式，前面字符串为附件的URI写法，后面表示此附件的类型；不能搞错，不能缺少
String szSelectedFiles[]={"file:///sdcard/ebook/CityCodes.xml", "text/xml","file:///sdcard/ebook/PhoneBookU.txt", "text/plain", "file:///sdcard/windy.gif", "image/gif"};
it.putExtra(Intent.EXTRA_STREAM, szSelectedFiles);
//以下这一句照抄，无论你的附件是什么类型的
it.setType("audio/mp3");
startActivity(Intent.createChooser(it, "请选择Email客户端软件"));
第六种方法:
//实现单个附件的添加
Uri uri = Uri.parse("file:///sdcard/mysong.mp3");
Intent it = new Intent(Intent.ACTION_SEND);
it.putExtra(Intent.EXTRA_STREAM, uri);
it.putExtra(Intent.EXTRA_SUBJECT, "The email subject text");
it.setType("audio/mp3");
startActivity(Intent.createChooser(it, "请选择Email客户端软件"));
