主要有三种方法:

String email = /* Your email address here */
String subject = /* Your subject here */
String body = /* Your body here */
String chooserTitle = /* Your chooser title here */

1. 自定义Uri:

Uri uri = Uri.parse("mailto:" + email)
    .buildUpon()
    .appendQueryParameter("subject", subject)
    .appendQueryParameter("body", body)
    .build();

Intent emailIntent = new Intent(Intent.ACTION_SENDTO, uri);
startActivity(Intent.createChooser(emailIntent, chooserTitle));

2. 使用Intent附加:

Intent emailIntent = new Intent(Intent.ACTION_SENDTO, Uri.parse("mailto:" + email));
emailIntent.putExtra(Intent.EXTRA_SUBJECT, subject);
emailIntent.putExtra(Intent.EXTRA_TEXT, body);
//emailIntent.putExtra(Intent.EXTRA_HTML_TEXT, body); //If you are using HTML in your body text

startActivity(Intent.createChooser(emailIntent, "Chooser Title"));

3.支持库ShareCompat:

Activity activity = /* Your activity here */

ShareCompat.IntentBuilder.from(activity)
    .setType("message/rfc822")
    .addEmailTo(email)
    .setSubject(subject)
    .setText(body)
    //.setHtmlText(body) //If you are using HTML in your body text
    .setChooserTitle(chooserTitle)
    .startChooser();

这是一个迟来的答案，尽管我想出了一个可以帮助其他人的解决方案:

Java版本

Intent emailIntent = new Intent(Intent.ACTION_SENDTO);
emailIntent.setData(Uri.parse("mailto:abc@xyz.com"));
startActivity(Intent.createChooser(emailIntent, "Send feedback"));

芬兰湾的科特林版本

val emailIntent = Intent(Intent.ACTION_SENDTO).apply { 
    data = Uri.parse("mailto:abc@xyz.com")
}
startActivity(Intent.createChooser(emailIntent, "Send feedback"))

这是我的输出(只有Gmail +收件箱建议):

我从Android开发者网站上得到了这个解决方案。

如果你想确保你的意图只被电子邮件应用程序处理(而不是其他短信或社交应用程序)，那么使用ACTION_SENDTO动作并包括“mailto:”数据方案。例如:

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);
    }
}

我在https://developer.android.com/guide/components/intents-common.html#Email上找到了这个

String sendEmailTo = "abc@xyz.com";
String subject = "Subject";
String body = "Body";
            
Uri uri = Uri.parse("mailto:"+sendEmailTo+"?subject="+subject+"&body="+body);
    
startActivity(new Intent(Intent.ACTION_VIEW, uri);

这对我很管用。这将只在意图选择器中显示邮件应用程序。

另外: 我使用这种方法遇到的一个问题是我无法在建议和正文中添加空格。 因此，要在建议或正文文本中放置空格，请将空格替换为%20

请使用以下代码:

try {
    String uriText =
            "mailto:emailid" +
                    "?subject=" + Uri.encode("Feedback for app") +
                    "&body=" + Uri.encode(deviceInfo);
    Uri uri = Uri.parse(uriText);
    Intent emailIntent = new Intent(Intent.ACTION_SENDTO);
    emailIntent.setData(uri);
    startActivity(Intent.createChooser(emailIntent, "Send email using..."));
} catch (android.content.ActivityNotFoundException ex) {
    Toast.makeText(ContactUsActivity.this, "No email clients installed.", Toast.LENGTH_SHORT).show();
}            

如果您想要以Gmail为目标，那么您可以执行以下操作。注意，意图是“ACTION_SENDTO”而不是“ACTION_SEND”，额外的意图字段对于Gmail是不必要的。

String uriText =
    "mailto:youremail@gmail.com" + 
    "?subject=" + Uri.encode("your subject line here") + 
    "&body=" + Uri.encode("message body here");

Uri uri = Uri.parse(uriText);

Intent sendIntent = new Intent(Intent.ACTION_SENDTO);
sendIntent.setData(uri);
if (sendIntent.resolveActivity(getPackageManager()) != null) {
   startActivity(Intent.createChooser(sendIntent, "Send message")); 
}
