java - Android Studio mailto Intent 不显示主题和邮件正文

Question

我正在尝试从我的 Android 应用程序发送电子邮件。单击按钮后，gmail 应会打开并显示一封新电子邮件，其中包含我之前定义的收件人、主题和电子邮件正文。到目前为止，我已经尝试发送 Intent.ACTION_VIEW 和 Intent.ACTION_SENDTO。两者都只向收件人显示我的草稿。主题和信息都受到压迫。奇怪的是，当使用模拟器时，它工作得很好。还试图锁定 android 错误日志。好像我没有权限。这真的是权限问题还是其他问题？我真的很感激任何帮助干杯

这是我的代码:

• 通过 ACTION_VIEW 发送电子邮件

Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("mailto:" + to));
intent.putExtra(intent.EXTRA_SUBJECT, subject);
intent.putExtra(intent.EXTRA_TEXT, message);
mainActivity.startActivity(intent);

• 通过 ACTION_SENDTO 发送电子邮件

Intent email = new Intent(Intent.ACTION_SENDTO);
email.setType("message/rfc822");
email.putExtra(Intent.EXTRA_EMAIL, new String[]{to});
email.putExtra(Intent.EXTRA_SUBJECT, subject);
email.putExtra(Intent.EXTRA_TEXT, message);
mainActivity.startActivity(Intent.createChooser(email, "Choose an Email client :"));

• 来自 logcat 的错误消息

Answer 1

我想我们遇到了同样的问题。 Android API 29 引入了一些关于向其他应用程序发送数据的改进。在此处查看更多详细信息:Sending simple data to other apps

这是适合我的解决方案。

Intent selectorIntent = new Intent(Intent.ACTION_SENDTO);
selectorIntent.setData(Uri.parse("mailto:"));

final Intent emailIntent = new Intent(Intent.ACTION_SEND);
emailIntent.putExtra(Intent.EXTRA_EMAIL, new String[]{"address@mail.com"});
emailIntent.putExtra(Intent.EXTRA_SUBJECT, "The subject");
emailIntent.putExtra(Intent.EXTRA_TEXT, "The email body");
emailIntent.setSelector( selectorIntent );

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

简而言之，您要求使用 Android 标准应用程序选择器，此外，您指定要发送电子邮件。因此，结果只会出现电子邮件客户端。如果用户只安装了一个电子邮件客户端， Intent 将立即重定向到它。

希望这对你也有帮助。
