【问题描述】：

我一直在尝试发送带有附件的电子邮件。 也只寻找电子邮件客户回复。

我已关注此链接Send Email Intent。

下面是我的代码

Intent intent = new Intent(Intent.ACTION_SENDTO);
// Set MIME type to email message to avoid other non-email applications showing up

        intent.setData(Uri.parse("mailto:"));
        intent.putExtra(Intent.EXTRA_EMAIL, to);
        intent.putExtra(Intent.EXTRA_SUBJECT, subject);
        intent.putExtra(Intent.EXTRA_TEXT, body);
        intent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, attachments);

这样做，我在选择器对话框中获得了 gmail 和 android 电子邮件客户端。 当我点击 gmail 客户端时，出现以下错误。同样适用于 android 电子邮件客户端。

干杯， 索拉夫

【问题讨论】：

添加intent.setType("text/plain");

嗨，Shayan 感谢您的投入。我添加了 intent.setType("message/rfc822") 但仍然得到相同的异常

你的链接上看到doreamon的回答了吗？

我什至试过这个。我没工作。意图 emailIntent = new Intent(Intent.ACTION_SENDTO, Uri.fromParts("mailto", "", null)); emailIntent.putExtra（Intent.EXTRA_SUBJECT，主题）； emailIntent.putExtra（Intent.EXTRA_TEXT，正文）； emailIntent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, attachments);

您是否记录了所有值，例如 to 和 subject 和 .. ？因为可能是其中之一

【参考方案1】：

请看一下

    final Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
                      emailIntent.setType("plain/text");
                      emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, new String[]"[e-mail]");
                     // emailIntent.putExtra(android.content.Intent.EXTRA_BCC, new String[]etEmail.getText().toString());
                      emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, getResources().getString(R.string.feedback_for)+"an interesting place");
                      emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, etComment.getText().toString()+"\n\n"+getResources().getString(R.string.rating)+rbRating.getRating()+"\n"+getResources().getString(R.string.my_contact_number)+etPhoneNumber.getText().toString());
                      startActivity(Intent.createChooser(emailIntent, getResources

().getString(R.string.chooser_send_feedback)));

【讨论】：

但据我了解，“plain/text”类型的 action_send 将列出所有其他响应这种意图的应用程序

是的，它可以，所以我会找到另一个解决方案，如果我能得到并且会通知你

感谢 Jitesh...抱歉，如果我最初的问题不清楚...已更新
