Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("text/html");
intent.putExtra(Intent.EXTRA_EMAIL, "emailaddress@emailaddress.com");
intent.putExtra(Intent.EXTRA_SUBJECT, "Subject");
intent.putExtra(Intent.EXTRA_TEXT, "I'm email body.");
startActivity(Intent.createChooser(intent, "Send Email"));

上面的代码打开一个对话框,显示以下应用程序:-蓝牙,谷歌文档,雅虎邮件,Gmail, Orkut, Skype等。

实际上,我想过滤这些列表选项。我只想显示电子邮件相关的应用程序,如Gmail和雅虎邮件。怎么做呢?

我曾在Android Market应用中看到过这样的例子。

打开Android Market应用程序 打开任何开发者指定了他/她的电子邮件地址的应用程序。(如果你找不到这样的应用程序,请打开我的应用程序:- market://details?id=com.becomputer06.vehicle.diary.free,或通过“车辆日记”搜索) 向下滚动到“开发者” 点击“发送电子邮件”

对话框只显示电子邮件应用程序,如Gmail,雅虎邮件等。它不显示蓝牙,Orkut等。什么样的代码产生这样的对话?

这段代码在我的设备中工作

Intent mIntent = new Intent(Intent.ACTION_SENDTO);
mIntent.setData(Uri.parse("mailto:"));
mIntent.putExtra(Intent.EXTRA_EMAIL  , new String[] {"mahendrarajdhami@gmail.com"});
mIntent.putExtra(Intent.EXTRA_SUBJECT, "");
startActivity(Intent.createChooser(mIntent, "Send Email Using..."));

适用于所有android版本:

String[] to = {"email@server.com"};
Uri uri = Uri.parse("mailto:email@server.com")
  .buildUpon()
  .appendQueryParameter("subject", "subject")
  .appendQueryParameter("body", "body")
  .build();
Intent emailIntent = new Intent(ACTION_SENDTO, uri);
emailIntent.putExtra(EXTRA_EMAIL, TO);
startActivity(Intent.createChooser(emailIntent, "Send mail..."));

更新到Android 10,现在使用Kotlin…

fun Context.sendEmail(
  address: String?,
  subject: String?,
  body: String?,
) {
  val recipients = arrayOf(address)
  val uri = address.toUri()
    .buildUpon()
    .appendQueryParameter("subject", subject)
    .appendQueryParameter("body", body)
    .build()
  val emailIntent = Intent(ACTION_SENDTO, uri).apply {
    setData("mailto:$address".toUri());
    putExtra(EXTRA_SUBJECT, subject);
    putExtra(EXTRA_TEXT, body);
    putExtra(EXTRA_EMAIL, recipients)
  }
  val pickerTitle = getString(R.string.some_title)
  ContextCompat.startActivity(this, Intent.createChooser(emailIntent, pickerTitle, null)
}

...在更新到API 30之后,代码没有填充电子邮件客户端的主题和主体(例如Gmail)。但我在这里找到了答案:

fun Context.sendEmail(
  address: String?,
  subject: String?,
  body: String?,
) {
  val selectorIntent = Intent(ACTION_SENDTO)
    .setData("mailto:$address".toUri())
  val emailIntent = Intent(ACTION_SEND).apply {
    putExtra(EXTRA_EMAIL, arrayOf(address))
    putExtra(EXTRA_SUBJECT, subject)
    putExtra(EXTRA_TEXT, body)
    selector = selectorIntent
  }
  startActivity(Intent.createChooser(emailIntent, getString(R.string.send_email))) 

}

这是引用自Android官方文档,我已经在Android 4.4上进行了测试,工作完美。更多例子见https://developer.android.com/guide/components/intents-common.html#Email

public void composeEmail(String[] addresses, String subject) {
    Intent intent = new Intent(Intent.ACTION_SENDTO);
    intent.setData(Uri.parse("mailto:")); // only email apps should handle this
    intent.putExtra(Intent.EXTRA_EMAIL, addresses);
    intent.putExtra(Intent.EXTRA_SUBJECT, subject);
    if (intent.resolveActivity(getPackageManager()) != null) {
        startActivity(intent);
    }
}

与Kotlin,工作与Gmail:

val i = Intent(Intent.ACTION_SENDTO).apply {
    type = "text/html"
    data = Uri.parse("mailto:")
    putExtra(Intent.EXTRA_EMAIL, arrayOf(email))
    putExtra(Intent.EXTRA_SUBJECT, subject)
    putExtra(Intent.EXTRA_TITLE, subject)
}
if (packageManager != null && i.resolveActivity(packageManager) != null) {
    startActivity(i)
}

如果有人找到一个解决方案来显示消息…

使用intent.setType(”消息/根据rfc822”以);工作,但它显示额外的应用程序,不一定处理电子邮件(如GDrive)。使用意图。ACTION_SENDTO与setType("text/plain")是最好的,但你必须添加setData(Uri.parse("mailto:")),以获得最好的结果(仅电子邮件应用程序)。完整代码如下:

Intent intent = new Intent(Intent.ACTION_SENDTO);
intent.setType("text/plain");
intent.setData(Uri.parse("mailto:IT@RMAsoft.NET"));
intent.putExtra(Intent.EXTRA_SUBJECT, "Email from My app");
intent.putExtra(Intent.EXTRA_TEXT, "Place your email message here ...");
startActivity(Intent.createChooser(intent, "Send Email"));

这对我来说很管用:

Intent intent = new Intent(Intent.ACTION_SENDTO);
intent.setData(Uri.parse("mailto:"));
intent.putExtra(Intent.EXTRA_EMAIL, new String[] { "me@somewhere.com" });
intent.putExtra(Intent.EXTRA_SUBJECT, "My subject");

startActivity(Intent.createChooser(intent, "Email via..."));

最重要的是:使用ACTION_SENDTO动作而不是ACTION_SEND动作。我在一些Android 4.4设备上尝试了它,结果是:

它正确地限制选择弹出只显示电子邮件应用程序(电子邮件,Gmail,雅虎邮件等);而且 它正确地将电子邮件地址和主题插入到电子邮件中。
