Kotlin版本，只显示电子邮件客户端(没有联系人等):

    with(Intent(Intent.ACTION_SEND)) {
        type = "message/rfc822"
        data = Uri.parse("mailto:")
        putExtra(Intent.EXTRA_EMAIL, arrayOf("user@example.com"))
        putExtra(Intent.EXTRA_SUBJECT,"YOUR SUBJECT")
        putExtra(Intent.EXTRA_TEXT, "YOUR BODY")
        try {
            startActivity(Intent.createChooser(this, "Send Email with"))
        } catch (ex: ActivityNotFoundException) {
            // No email clients found, might show Toast here
        }
    }

为了发送带有附加二进制错误日志文件的电子邮件，我使用了当前接受的答案。GMail和K-9发送得很好，在我的邮件服务器上也很好。唯一的问题是我选择的邮件客户端Thunderbird，它在打开/保存附加的日志文件时遇到了麻烦。事实上，它根本没有保存文件，没有抱怨。

我查看了其中一封邮件的源代码，注意到日志文件附件具有mime类型消息/rfc822(这是可以理解的)。当然这个附件不是附件邮件。但雷鸟无法优雅地处理这个微小的错误。所以这有点令人沮丧。

经过一些研究和实验，我想出了以下解决方案:

public Intent createEmailOnlyChooserIntent(Intent source,
    CharSequence chooserTitle) {
    Stack<Intent> intents = new Stack<Intent>();
    Intent i = new Intent(Intent.ACTION_SENDTO, Uri.fromParts("mailto",
            "info@example.com", null));
    List<ResolveInfo> activities = getPackageManager()
            .queryIntentActivities(i, 0);

    for(ResolveInfo ri : activities) {
        Intent target = new Intent(source);
        target.setPackage(ri.activityInfo.packageName);
        intents.add(target);
    }

    if(!intents.isEmpty()) {
        Intent chooserIntent = Intent.createChooser(intents.remove(0),
                chooserTitle);
        chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS,
                intents.toArray(new Parcelable[intents.size()]));

        return chooserIntent;
    } else {
        return Intent.createChooser(source, chooserTitle);
    }
}

它可以这样使用:

Intent i = new Intent(Intent.ACTION_SEND);
i.setType("*/*");
i.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(crashLogFile));
i.putExtra(Intent.EXTRA_EMAIL, new String[] {
    ANDROID_SUPPORT_EMAIL
});
i.putExtra(Intent.EXTRA_SUBJECT, "Crash report");
i.putExtra(Intent.EXTRA_TEXT, "Some crash report details");

startActivity(createEmailOnlyChooserIntent(i, "Send via email"));

如您所见，可以很容易地为createEmailOnlyChooserIntent方法提供正确的意图和正确的mime类型。

然后，它遍历响应ACTION_SENDTO邮件协议意图(仅是电子邮件应用程序)的可用活动列表，并基于该活动列表和具有正确mime类型的原始ACTION_SEND意图构造一个选择器。

另一个优点是Skype不再被列出(这恰好响应rfc822 mime类型)。

 Intent emailIntent = new Intent(Intent.ACTION_SENDTO, Uri.fromParts(
            "mailto","ebgsoldier@gmail.com", null));
    emailIntent.putExtra(Intent.EXTRA_SUBJECT, "Forgot Password");
    emailIntent.putExtra(Intent.EXTRA_TEXT, "this is a text ");
    startActivity(Intent.createChooser(emailIntent, "Send email..."));

简单，试试这个

 public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    buttonSend = (Button) findViewById(R.id.buttonSend);
    textTo = (EditText) findViewById(R.id.editTextTo);
    textSubject = (EditText) findViewById(R.id.editTextSubject);
    textMessage = (EditText) findViewById(R.id.editTextMessage);

    buttonSend.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {

            String to = textTo.getText().toString();
            String subject = textSubject.getText().toString();
            String message = textMessage.getText().toString();

            Intent email = new Intent(Intent.ACTION_SEND);
            email.putExtra(Intent.EXTRA_EMAIL, new String[] { to });
            // email.putExtra(Intent.EXTRA_CC, new String[]{ to});
            // email.putExtra(Intent.EXTRA_BCC, new String[]{to});
            email.putExtra(Intent.EXTRA_SUBJECT, subject);
            email.putExtra(Intent.EXTRA_TEXT, message);

            // need this to prompts email client only
            email.setType("message/rfc822");

            startActivity(Intent.createChooser(email, "Choose an Email client :"));

        }
    });
}

使用. settype ("message/rfc822")或ACTION_SEND的策略似乎也适用于非电子邮件客户端的应用程序，如Android Beam和蓝牙。

使用ACTION_SENDTO和mailto: URI似乎工作得很好，并且在开发人员文档中推荐使用。但是，如果你在官方模拟器上这样做，并且没有设置任何电子邮件帐户(或者没有任何邮件客户端)，你会得到以下错误:

不支持的操作 目前不支持该操作。

如下图所示:

结果是模拟器将意图解析为一个名为com.android.fallback的活动。Fallback，它显示上面的消息。显然这是故意的。

如果你想让你的应用在官方模拟器上也能正常运行，你可以在发送邮件之前检查一下:

private void sendEmail() {
    Intent intent = new Intent(Intent.ACTION_SENDTO)
        .setData(new Uri.Builder().scheme("mailto").build())
        .putExtra(Intent.EXTRA_EMAIL, new String[]{ "John Smith <johnsmith@yourdomain.com>" })
        .putExtra(Intent.EXTRA_SUBJECT, "Email subject")
        .putExtra(Intent.EXTRA_TEXT, "Email body")
    ;

    ComponentName emailApp = intent.resolveActivity(getPackageManager());
    ComponentName unsupportedAction = ComponentName.unflattenFromString("com.android.fallback/.Fallback");
    if (emailApp != null && !emailApp.equals(unsupportedAction))
        try {
            // Needed to customise the chooser dialog title since it might default to "Share with"
            // Note that the chooser will still be skipped if only one app is matched
            Intent chooser = Intent.createChooser(intent, "Send email with");
            startActivity(chooser);
            return;
        }
        catch (ActivityNotFoundException ignored) {
        }

    Toast
        .makeText(this, "Couldn't find an email app and account", Toast.LENGTH_LONG)
        .show();
}

在开发人员文档中找到更多信息。

我很久以前就一直在用这个，看起来不错，没有非电子邮件应用程序显示。这是发送电子邮件意图的另一种方式:

Intent intent = new Intent(Intent.ACTION_SENDTO); // it's not ACTION_SEND
intent.putExtra(Intent.EXTRA_SUBJECT, "Subject of email");
intent.putExtra(Intent.EXTRA_TEXT, "Body of email");
intent.setData(Uri.parse("mailto:default@example.com")); // or just "mailto:" for blank
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); // this will make such that when user returns to your app, your app is displayed, instead of the email app.
startActivity(intent);
