android - Intent 中的附件问题

Question

我一直在开发 Android 程序，使用 Intent 发送带有附件(文本/纯文本)的电子邮件与 Intent.ACTION_SEND我用了Intent.putParcelableArrayListExtra(android.content.Intent.EXTRA_STREAM, uri)但是，当我尝试通过调用 Intent.putExtra(android.content.Intent.EXTRA_STREAM, uri) 将多个文件附加到同一封邮件时多次，它没有工作。电子邮件中未显示任何附件。提前致谢

      final Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
      System.out.println(emailText+emailTo);
      emailIntent.setType("text/plain");
      emailIntent.putExtra(android.content.Intent.EXTRA_TEXT,emailText);
      emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, subject);
      emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL,new String[]{emailTo});

      //has to be an ArrayList
      ArrayList<Uri> uris = new ArrayList<Uri>();

      //convert from paths to Android friendly Parcelable Uri's
      try
      {
            for (String file : filePaths)
            {
                File fileIn = new File(context.getFilesDir(),file);
                System.out.println(fileIn+"yes");
                Uri u =  Uri.fromFile(fileIn);
                uris.add(u);
                System.out.println(u);
            }
      emailIntent.putParcelableArrayListExtra(Intent.EXTRA_STREAM,uris);
      context.startActivity(Intent.createChooser(emailIntent, "Send mail..."));
      }

使用 ACTION_SEND_MUTIPLE 而不是 ACTION_SEND

http://developer.android.com/reference/android/content/Intent.html#ACTION_SEND_MULTIPLE

final Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND_MULTIPLE);
