Question

我想在邮件中附上.vcf文件并通过邮件发送。但邮件是在没有附件的地址上收到的。我使用了下面的代码，但代码是这个，我不知道我错在哪里。

try {      
  String filelocation="/mnt/sdcard/contacts_sid.vcf";      
  Intent intent = new Intent(Intent.ACTION_SENDTO);    
  intent.setType("text/plain");      
  intent.putExtra(Intent.EXTRA_SUBJECT, "");      
  intent.putExtra(Intent.EXTRA_STREAM, Uri.parse( "file://"+filelocation));      
  intent.putExtra(Intent.EXTRA_TEXT, message);         
  intent.setData(Uri.parse("mailto:"));         
  intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 

  activity.startActivity(intent);
  activity.finish();
  } catch(Exception e)  {
     System.out.println("is exception raises during sending mail"+e);
}

使用以下代码在电子邮件中发送文件。

String filename="contacts_sid.vcf"; 
File filelocation = new File(Environment.getExternalStorageDirectory().getAbsolutePath(), filename);
Uri path = Uri.fromFile(filelocation); 
Intent emailIntent = new Intent(Intent.ACTION_SEND);
// set the type to 'email'
emailIntent .setType("vnd.android.cursor.dir/email");
String to[] = {"asd@gmail.com"};
emailIntent .putExtra(Intent.EXTRA_EMAIL, to);
// the attachment
emailIntent .putExtra(Intent.EXTRA_STREAM, path);
// the mail subject
emailIntent .putExtra(Intent.EXTRA_SUBJECT, "Subject");
startActivity(Intent.createChooser(emailIntent , "Send email..."));

Folder_name是手机内部存储中的文件名。（实际上是EXTERNAL_STORAGE）。 file_name是您要发送的文件的名称。

private void ShareViaEmail(String folder_name, String file_name) {
    try {
        File Root= Environment.getExternalStorageDirectory();
        String filelocation=Root.getAbsolutePath() + folder_name + "/" + file_name;
        Intent intent = new Intent(Intent.ACTION_SENDTO);
        intent.setType("text/plain");
        String message="File to be shared is " + file_name + ".";
        intent.putExtra(Intent.EXTRA_SUBJECT, "Subject");
        intent.putExtra(Intent.EXTRA_STREAM, Uri.parse( "file://"+filelocation));
        intent.putExtra(Intent.EXTRA_TEXT, message);
        intent.setData(Uri.parse("mailto:xyz@gmail.com"));
        intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

        startActivity(intent);
    } catch(Exception e)  {
        System.out.println("is exception raises during sending mail"+e);
    }
}

官方Android site上的例子为我工作。所有需要它添加

startActivity(Intent.createChooser(emailIntent , "Send email..."));

像在Agarwal的回答中所做的那样

SENDTO不支持附件。我已使用Provider添加了我的答案来读取文件信息。它在Kotlin。

fun shareFile(context: Context, filePath: File?, fileShareInfo: FileShareInfo) {

    val intentFileShare = Intent(Intent.ACTION_SEND)

    if (filePath!!.exists()) {
        intentFileShare.type = fileShareInfo.fileType
        val uri = FileProvider.getUriForFile(context, BuildConfig.APPLICATION_ID + ".provider", filePath)
        intentFileShare.putExtra(Intent.EXTRA_STREAM, uri)
        fileShareInfo.recipients?.let {
            intentFileShare.putExtra(Intent.EXTRA_EMAIL, fileShareInfo.recipients)
        }
        intentFileShare.putExtra(Intent.EXTRA_SUBJECT, fileShareInfo.shareSubjectText)
        fileShareInfo.shareExtraText?.let {
            intentFileShare.putExtra(Intent.EXTRA_TEXT, AppViewUtil.fromHtml(fileShareInfo.shareExtraText!!))
        }
        try {
            ContextCompat.startActivity(context, Intent.createChooser(intentFileShare, fileShareInfo.shareTitle), null)
        } catch (e: ActivityNotFoundException) {
            Toast.makeText(context, context.getString(R.string.sharing_no_app_found), Toast.LENGTH_LONG).show()
        }

    }
}

我在Kotlin中编写了一个扩展程序，用于发送带有多个附件的电子邮件。我希望它对某人有用。

fun AppCompatActivity.sendEmail(subject: String, content: String, email: String, fileAttachments: List<String> = emptyList()) {

    val emailIntent = Intent(Intent.ACTION_SEND_MULTIPLE).apply {
        type = "text/html"
        putExtra(Intent.EXTRA_SUBJECT, subject)
        addFlags(Intent.FLAG_ACTIVITY_NEW_TASK)
        putExtra(Intent.EXTRA_TEXT, content)
        putExtra(Intent.EXTRA_EMAIL, arrayOf(email))

        // Configure attachments
        val attachments = fileAttachments.map { File(it) }.filter { it.exists() && !it.isDirectory }.map {
            FileProvider.getUriForFile(baseContext, "${BuildConfig.APPLICATION_ID}.fileprovider", it)
        }.toList()

        if(attachments.isNotEmpty())
            putParcelableArrayListExtra(Intent.EXTRA_STREAM, ArrayList(attachments))
    }

    if (emailIntent.resolveActivity(packageManager) != null)
        startActivity(Intent.createChooser(emailIntent, "Chooser Mail Client"))
}
