使Java中的电子邮件正文文本变为粗体，斜体和更大 [英] Make text bold, italic, and bigger for email body in java

问题描述

我发送一封电子邮件，其中包含在整个应用程序中检索到的数据，例如：

I send an E-mail with data retrieved throughout my application like such:

String body = formatEmailBody();

Intent i = new Intent(Intent.ACTION_SEND);
i.setType("message/rfc822");
i.putExtra(Intent.EXTRA_EMAIL  , new String[]{"[e-mail]"}); // Set receipient here
i.putExtra(Intent.EXTRA_SUBJECT, "Subject");
i.putExtra(Intent.EXTRA_TEXT   , body);
try {
    startActivity(Intent.createChooser(i, "Send mail..."));
} catch (android.content.ActivityNotFoundException ex) {
    Toast.makeText(MainActivity.this, "There are no email clients installed.", Toast.LENGTH_SHORT).show();
}

其中 formatEmailBody 创建一个 String 作为邮件正文发送。

Where formatEmailBody simply creates a String to be send as body of my email.

但是一个简单的字符串很无聊，我怎么可能

But a simple string is boring, how may I add bold / italic / bigger text?

我尝试了以下操作但没有成功：

I have tried the following to no success:

Html.fromHtml(new StringBuilder()
            .append("<p><b>Some Content</b></p>")
            .append("<small><p>More content</p></small>")
            .toString()));

推荐答案

您是否看过意图，尤其是常量部分，您会在其中看到：

Have you taken a look into Intent, especially the section "Constants", where you see :

EXTRA_HTML_TEXT：
与Intent关联的常量字符串，与ACTION_SEND一起使用，以HTML格式的文本形式替代EXTRA_TEXT。

EXTRA_HTML_TEXT : A constant String that is associated with the Intent, used with ACTION_SEND to supply an alternative to EXTRA_TEXT as HTML formatted text.

但请注意此处：

与Intent关联的常量字符串，用于ACTION_SEND以提供替代EXTRA_TEXT作为HTML格式的文本。请注意，您还必须提供EXTRA_TEXT。

A constant String that is associated with the Intent, used with ACTION_SEND to supply an alternative to EXTRA_TEXT as HTML formatted text. Note that you must also supply EXTRA_TEXT.

因此，类似下面的内容可以提高html内容正确显示的几率：-

So something like the below should improve the odds of the html content being displayed correctly :-

i.setType("text/html");
i.putExtra(Intent.EXTRA_HTML_TEXT, htmlText);
i.putExtra(Intent.EXTRA_TEXT, Html.fromHtml(htmlText));
