如何在android中将所有联系人信息导出为VCF文件

使用此代码我可以导出我设置的任何值，但除此之外我想保存图像，生日，关系，assistnat，注释，标签，网站。

如何设置这个值来生成vcf文件？

Person p = getPerson();

File vcfFile = new File(this.getExternalFilesDir(null), "generated.vcf");
FileWriter fw = new FileWriter(vcfFile);
fw.write("BEGIN:VCARD\r\n");
fw.write("VERSION:3.0\r\n");
fw.write("N:" + p.getSurname() + ";" + p.getFirstName() + "\r\n");
fw.write("FN:" + p.getFirstName() + " " + p.getSurname() + "\r\n");
fw.write("ORG:" + p.getCompanyName() + "\r\n");
fw.write("TITLE:" + p.getTitle() + "\r\n");
fw.write("TEL;TYPE=WORK,VOICE:" + p.getWorkPhone() + "\r\n");
fw.write("TEL;TYPE=HOME,VOICE:" + p.getHomePhone() + "\r\n");
fw.write("ADR;TYPE=WORK:;;" + p.getStreet() + ";" + p.getCity() + ";" + p.getState() + ";" + p.getPostcode() + ";" + p.getCountry() + "\r\n");
fw.write("EMAIL;TYPE=PREF,INTERNET:" + p.getEmailAddress() + "\r\n");
fw.write("END:VCARD\r\n");
fw.close();

Intent i = new Intent();
i.setAction(android.content.Intent.ACTION_VIEW);
i.setDataAndType(Uri.fromFile(vcfFile), "text/x-vcard");
startActivity(i);

这是旧的胎面，但我希望它有帮助

我建议您阅读 vCard 的文档：https://www.rfc-editor.org/rfc/rfc2426 https://www.rfc-editor.org/rfc/rfc2426

对于图像：

fw.write("PHOTO;VALUE=uri:www.abc.net/pub/logos/abccorp.jpg\r\n");

or

fw.write("PHOTO;ENCODING=b;TYPE=JPEG:MIICajCCAdOgAwIBAgICBEUwDQYJKoZIhvcN
         AQEEBQAwdzELMAkGA1UEBhMCVVMxLDAqBgNVBAoTI05ldHNjYXBlIENvbW11bm
         ljYXRpb25zIENvcnBvcmF0aW9uMRwwGgYDVQQLExNJbmZvcm1hdGlvbiBTeXN0\r\n");
         //<...the remainder of "B" encoded binary data...>

生日：

fw.write("BDAY:1996-04-15\r\n");

为了关系

fw.write("ROLE:Programmer\r\n");

助理用

fw.write("AGENT:BEGIN:VCARD\nFN:Susan Thomas\nTEL:+1-919-555-
         1234\nEMAIL\;INTERNET:[email protected] /cdn-cgi/l/email-protection\nEND:VCARD\n\r\n");

对于笔记

fw.write("NOTE:This fax number is operational 0800 to 1715
          EST\, Mon-Fri.\r\n");

对于标签：

fw.write("LABEL;TYPE=dom,home,postal,parcel:Mr.John Q. Public\, Esq.\n
         Mail Drop: TNE QB\n123 Main Street\nAny Town\, CA  91921-1234
         \nU.S.A.\r\n");
