如何创建启动任何电子邮件应用程序的意图？

我在这里和其他地方找到了有关创建发送电子邮件意图的各种主题，这似乎非常简单。我正在寻找启动用户可能拥有的任何电子邮件客户端的意图。

这是我见过的用于发送电子邮件的代码（发布仅供参考，这不能满足我的需求，因为我不想发送新消息）：

Intent i = new Intent(Intent.ACTION_SEND); 
i.setType("text/plain"); 
i.putExtra(Intent.EXTRA_EMAIL  , new String[]{"[email protected]"}); 
i.putExtra(Intent.EXTRA_SUBJECT, "Subject of the message"); 
i.putExtra(Intent.EXTRA_TEXT   , "Body of the message");

这是我专门按包名称启动 Gmail 客户端的代码：

PackageManager pm = getPackageManager();
Intent intent = pm.getLaunchIntentForPackage("com.google.android.gm");
startActivity(intent);

上面的代码可以工作，但不灵活，因为用户可能不使用 Gmail，而是使用其他内置电子邮件应用程序或第 3 方电子邮件应用程序。我正在寻找一种意图，在这种情况下可以调出选择器，以便用户可以决定启动哪个应用程序来阅读电子邮件。

有谁知道如何做到这一点？

I have found various topics here and elsewhere on creating an intent for sending e-mail and that seems to be pretty straightforward. I'm looking for an intent to just launch any e-mail client the user might have.

Here is the code I've seen for sending an e-mail (posted just for reference, this doesn't serve my needs as I don't want to send a new message):

Intent i = new Intent(Intent.ACTION_SEND); 
i.setType("text/plain"); 
i.putExtra(Intent.EXTRA_EMAIL  , new String[]{"[email protected]"}); 
i.putExtra(Intent.EXTRA_SUBJECT, "Subject of the message"); 
i.putExtra(Intent.EXTRA_TEXT   , "Body of the message");

Here is the code I put together for specifically launching the Gmail client by package name:

PackageManager pm = getPackageManager();
Intent intent = pm.getLaunchIntentForPackage("com.google.android.gm");
startActivity(intent);

The code above works but isn't flexible in that a user might not be using Gmail but the other built-in e-mail application or a 3rd party e-mail app. I'm looking for an intent that would bring up the chooser in this case so the user can decide which app to launch to read e-mail.

Does anyone know how to accomplish this?

能否以某种方式使用 mailto URL 来实现此目的？
- 编辑 -
我能够使用以下代码示例来完成此任务：

mt = MailTo.parse("mailto:[email protected]");
sendIntent = new Intent(Intent.ACTION_SEND);
sendIntent.putExtra(Intent.EXTRA_EMAIL, new String[]{mt.getTo()});
sendIntent.putExtra(Intent.EXTRA_TEXT, "");
sendIntent.putExtra(Intent.EXTRA_SUBJECT, "Enter a subject");
sendIntent.setType("message/rfc822");
startActivity(Intent.createChooser(sendIntent, "Send a Message:"));

Can a mailto URL be used in some fashion to accomplish this?
--Edit--
I was able to accomplish this using the following code sample:

mt = MailTo.parse("mailto:[email protected]");
sendIntent = new Intent(Intent.ACTION_SEND);
sendIntent.putExtra(Intent.EXTRA_EMAIL, new String[]{mt.getTo()});
sendIntent.putExtra(Intent.EXTRA_TEXT, "");
sendIntent.putExtra(Intent.EXTRA_SUBJECT, "Enter a subject");
sendIntent.setType("message/rfc822");
startActivity(Intent.createChooser(sendIntent, "Send a Message:"));
