如何在安卓中打开gmail

Question

我只是想通过我的应用程序打开 Gmail 应用程序，并想从我的应用程序设置电子邮件、主题和消息。我尝试过 GmailService，但它不支持密件抄送或抄送电子邮件。链接：https ://github.com/yesidlazaro/GmailBackgroundBackgroundMail.newBuilder(this)    .withUsername("[e-mail]")    .withPassword("password12345")    .withMailto("[e-mail]")    .withType(BackgroundMail.TYPE_PLAIN)    .withSubject("this is the subject")    .withBody("this is the body")    .withOnSuccessCallback(new BackgroundMail.OnSuccessCallback() {        @Override        public void onSuccess() {            //do some magic        }    }).withOnFailCallback(new BackgroundMail.OnFailCallback() {        @Override        public void onFail() {            //do some magic        }    }).send();我想将密件抄送和抄送功能与附件、主题和消息一起使用。

Answer 1

// 对于任何应用程序的电子邮件

Intent email= new Intent(Intent.ACTION_SENDTO);
                email.setData(Uri.parse("mailto:[e-mail]"));
                email.putExtra(Intent.EXTRA_SUBJECT, "Subject");
                email.putExtra(Intent.EXTRA_TEXT, "My Email message");
                startActivity(email);

Answer 2

通过 Intent 打开 gmail

Intent intent = new Intent(Intent.ACTION_VIEW);

intent.setData(Uri.parse("[e-mail]"));

intent.setClassName("com.google.android.gm", "com.google.android.gm.ComposeActivityGmail");

intent.putExtra(Intent.EXTRA_CC, new String[]{"[e-mail]"});

intent.putExtra(Intent.EXTRA_BCC, new String[]{"[e-mail]"});

intent.putExtra(Intent.EXTRA_SUBJECT, "your subject goes here...");

intent.putExtra(Intent.EXTRA_TEXT, "Your message content goes here...");

    

startActivity(intent);

只需在意图参数中传递EXTRA_CC&EXTRA_BCC

以下答案适用于android 11

Intent intent = new Intent(Intent.ACTION_SENDTO);

intent.setData(Uri.parse("mailto:"));

intent.putExtra(Intent.EXTRA_EMAIL, new String[]{"[e-mail]"});

intent.putExtra(Intent.EXTRA_SUBJECT, "Your subject here...");

intent.putExtra(Intent.EXTRA_TEXT,"Your message here...");

startActivity(intent);

val selectorIntent = Intent(Intent.ACTION_SENDTO)

selectorIntent.data = Uri.parse("mailto:")

val emailIntent = Intent(Intent.ACTION_SEND)

emailIntent.putExtra(Intent.EXTRA_EMAIL, arrayOf("[e-mail]"))

emailIntent.putExtra(Intent.EXTRA_SUBJECT, "Subject here...")

emailIntent.putExtra(Intent.EXTRA_TEXT, "Email Body...")

emailIntent.selector = selectorIntent

activity!!.startActivity(Intent.createChooser(emailIntent, "Send email..."))
