Question

我只是想通过我的应用程序打开Gmail应用程序，并想通过我的应用程序设置电子邮件，主题和消息。

我已经尝试过GmailService，但它不支持密件抄送或cc电子邮件。链接：https://github.com/yesidlazaro/GmailBackground

BackgroundMail.newBuilder(this)
    .withUsername("username@gmail.com")
    .withPassword("password12345")
    .withMailto("toemail@gmail.com")
    .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();

我想使用密件抄送和抄送功能以及附件，主题和消息。

Answer 1

通过Intent打开Gmail

Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse("abc@gmail.com"));
intent.setClassName("com.google.android.gm", "com.google.android.gm.ComposeActivityGmail");
intent.putExtra(Intent.EXTRA_CC, new String[]{"xyz@gmail.com"});
intent.putExtra(Intent.EXTRA_BCC, new String[]{"pqr@gmail.com"});
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和EXTRA_BCC

//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:your.eamil@gmail.com"));
                email.putExtra(Intent.EXTRA_SUBJECT, "Subject");
                email.putExtra(Intent.EXTRA_TEXT, "My Email message");
                startActivity(email);

Answer 3

我正在使用它来启动gmail应用。

val intent: Intent? = activity.packageManager.getLaunchIntentForPackage("com.google.android.gm")

    if (intent != null) {
        startActivity(intent)
    }
    else{
        showToast("Sorry...You don't have gmail app")
    }

Answer 4

//这是用gmail打开的

Intent i = new Intent(Intent.ACTION_SENDTO);
            i.setType("text/plain");
            i.setData(Uri.parse("mailto:"));
            i.putExtra(Intent.EXTRA_EMAIL  , new String[]{"recipient@gmail.com"});
            i.putExtra(Intent.EXTRA_SUBJECT, "Mail Subject");
            i.putExtra(Intent.EXTRA_TEXT   , "massage");
            i.setPackage("com.google.android.gm");
            try {
                startActivity(Intent.createChooser(i, "Send mail..."));
            } catch (android.content.ActivityNotFoundException ex) {
                Toast.makeText(AnotherActivity.this, "There are no email clients installed.", Toast.LENGTH_SHORT).show();
            }

Answer 5

我正在使用这个

Intent mailClient = new Intent(Intent.ACTION_VIEW);
mailClient.setClassName("com.google.android.gm", "com.google.android.gm.ConversationListActivity");
startActivity(mailClient);

您也可以尝试

final Intent intent = new Intent(Intent.ACTION_VIEW)
    .setType("plain/text")
    .setData(Uri.parse("test@gmail.com"))
    .setClassName("com.google.android.gm", "com.google.android.gm.ComposeActivityGmail")
    .putExtra(Intent.EXTRA_EMAIL, new String[]{"test@gmail.com"})
    .putExtra(Intent.EXTRA_SUBJECT, "test")
    .putExtra(Intent.EXTRA_TEXT, "hello. this is a message sent from my demo app :-)");
startActivity(intent);

用于大量电子邮件：

intent.putExtra(Intent.EXTRA_EMAIL, new String[] { "test@gmail.com" });

对于单个电子邮件：

intent.setData(Uri.parse("test@gmail.com"));

//这是针对Gmail应用的

Intent email= new Intent(Intent.ACTION_VIEW);
            email.setType("message/rfc822")
            .setData(Uri.parse("mailto:your.email@gmail.com"))
            .putExtra(Intent.EXTRA_EMAIL, "your.email@gmail.com")
            .putExtra(Intent.EXTRA_SUBJECT, "Subject")
            .putExtra(Intent.EXTRA_TEXT, "My Email message")
            .setPackage("com.google.android.gm");
            startActivity(email);
