电子邮件意图 邮件选择器

Question

我在使用应用程序时遇到了一个问题。这个应用程序的目的是收集数据并使用javamail将数据表单提交到指定的电子邮件地址。当用户单击按钮时，他们应该收到一个提示选择电子邮件客户端，但是当我测试它时，我没有得到这个提示。有人能告诉我我漏掉了什么吗？

嗨，我是Imran，这两行代码怎么样？emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, new String[] {"[e-mail]"});emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, emailaddress); - ρяσѕρєя K

将此emailIntent.setType("plain/text")替换为emailIntent.setType("text/plain")。 - ρяσѕρєя K

请参考此链接，它可能会对您有所帮助：http://www.vidyut.com/sunit/android/android_sendmail.html - Aerrow

请查看这个 Kotlin 回答：如果您只需要显示电子邮件应用程序，然后要打开收件箱（而不是打开新的电子邮件编写），则只需使用下面的函数。 - jamescodingnow

如果您只想从设备中安装的电子邮件客户端中进行选择，可以使用ACTION_SENTTO选项

String mailTo="[e-mail]";
Intent email_intent = new Intent(Intent.ACTION_SENDTO, Uri.fromParts("mailto",mailTo, null)); 
email_intent.putExtra(android.content.Intent.EXTRA_SUBJECT, "Subject text here"); 
email_intent.putExtra(android.content.Intent.EXTRA_TEXT,"Body text here"); 

startActivity(Intent.createChooser(email_intent, "Send email..."));

在真实设备上尝试使用此电子邮件意图...模拟器可能无法给出结果。

祝你好运。

谢谢，我在我的设备上尝试了这个，但它仍然无法显示电子邮件选择器；非常奇怪。这个意图应该在清单中触发吗？ - MADPADGE

一个建议是确保您在真实设备上安装了不止一个电子邮件客户端... - Kri

你也可以尝试使用 setType(message/rfc822)；这样可能只会显示安装在你设备上的邮件客户端... - Kri

谢谢，我找到了问题所在。是“getAdapter”导致的。一旦我将其注释掉并删除变量，它就完美地工作了。感谢您的帮助。 - MADPADGE

仅供记录：

一些电子邮件应用程序（例如 Gmail）期望在 extras 中使用 String[]，例如 EXTRA_EMAIL 和 EXTRA_CC，请使用 putExtra(String, String[]) 将其添加到您的意图中。

Android 开发者页面

val sendIntent: Intent = Intent().apply {
            action = Intent.ACTION_SEND
            putExtra(Intent.EXTRA_EMAIL, arrayOf("[e-mail]"))
            putExtra(Intent.EXTRA_SUBJECT, "subject")
            putExtra(Intent.EXTRA_TEXT, "content")
            type = "text/plain"
}

startActivity(Intent.createChooser(sendIntent, "Send mail"))
