我发现了一种使用意图发送纯文本电子邮件：

i found a way to send plain text email using intent:

final Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
emailIntent.setType("text/plain"); 
emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, new     
String[]{"example@mail.com"}); 
emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "Subject"); 
emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, "Test");

但我需要发送HTML格式的文本。 尝试的setType（text / html的）不工作。

But I need to send HTML formatted text. Trying to setType("text/html") doesn't work.

推荐答案

您可以通过跨区在额外的文本。为确保意图解析才活动处理电子邮件（如Gmail和电子邮件应用程序），你可以使用 ACTION_SENDTO 用开放的开头mailto方案。这也将工作，如果你不知道收件人事先：

You can pass Spanned text in your extra. To ensure that the intent resolves only to activities that handle email (e.g. Gmail and Email apps), you can use ACTION_SENDTO with a Uri beginning with the mailto scheme. This will also work if you don't know the recipient beforehand:

final Intent shareIntent = new Intent(Intent.ACTION_SENDTO, Uri.parse("mailto:"));
shareIntent.putExtra(Intent.EXTRA_SUBJECT, "The Subject");
shareIntent.putExtra(
Intent.EXTRA_TEXT,
Html.fromHtml(new StringBuilder()
    .append("<p><b>Some Content</b></p>")
    .append("<small><p>More content</p></small>")
    .toString())
);
