Intent.EXTRA_EMAIL 未填充“收件人”字段

Question

我正在尝试使用intent 从我的应用程序发送电子邮件，但电子邮件的“收件人”字段不会填充。如果我添加代码来填写主题或文本，它们就可以正常工作。只有收件人字段不会填充。

我也尝试将类型更改为“text/plain”和“text/html”，但我遇到了同样的问题。有人可以帮忙吗？

public void Email(){

    Intent emailIntent = new Intent(Intent.ACTION_SEND); 
    emailIntent.setType("message/rfc822");  //set the email recipient
    String recipient = getString(R.string.IntegralEmailAddress);
    emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL  , recipient);
    //let the user choose what email client to use
    startActivity(Intent.createChooser(emailIntent, "Send mail using...")); }

我尝试使用的电子邮件客户端是 Gmail

Answer 1

我认为您没有将recipient 传递为array of string

应该是这样的

emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL,new String[] { "someone@gmail.com" });

Answer 2

使用这个

public void Email(){
    // use this to declare your 'recipient' string and get your email recipient from your string xml file
    Resources res = getResources();
    String recipient = getString(R.string.IntegralEmailAddress);
    Intent emailIntent = new Intent(Intent.ACTION_SEND); 
    emailIntent.setType("message/rfc822");  //set the email recipient
    emailIntent.putExtra(Intent.EXTRA_EMAIL, recipient);
    //let the user choose what email client to use
    startActivity(Intent.createChooser(emailIntent, "Send mail using...")); 

``}

这会起作用:)
这是关于 Intent.Extra_Email
的 android 文档所说的 - 所有“收件人”电子邮件地址的字符串数组。
所以你应该正确地喂字符串 你可以在这里阅读更多内容
http://developer.android.com/guide/components/intents-common.html#Email 在这里http://developer.android.com/guide/topics/resources/string-resource.html 或使用 ACTION_SENDTO 操作并包含“mailto：”数据方案。例如：

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);
}

在 Kotlin 中 - Android

fun sendMail(
        activity: Activity,
        emailIds: Array<String>,
        subject: String,
        textMessage: String
    ) {


        val emailIntent = Intent(Intent.ACTION_SEND)
        emailIntent.type = "text/plain"
        emailIntent.putExtra(Intent.EXTRA_EMAIL, emailIds)
        emailIntent.putExtra(Intent.EXTRA_SUBJECT, subject)
        emailIntent.putExtra(Intent.EXTRA_TEXT, textMessage)
        emailIntent.setType("message/rfc822")
        try {
            activity.startActivity(
                Intent.createChooser(
                    emailIntent,
                    "Send email using..."
                )
            )
        } catch (ex: ActivityNotFoundException) {
            Toast.makeText(
                activity,
                "No email clients installed.",
                Toast.LENGTH_SHORT
            ).show()
        }
    }

您也可以使用 [ val emailIntent = Intent(Intent.ACTION_SENDTO) ] 调用直接电子邮件 客户

//argument of function
val subject = "subject of you email"
val eMailMessageTxt = "Add Message here"

val eMailId1 = "emailId1@gmail.com"
val eMailId2 = "emailId2@gmail.com"
val eMailIds: Array<String> = arrayOf(eMailId1,eMailId2)

//Calling function
sendMail(this, eMailIds, subject, eMailMessageTxt)

希望这段代码 sn-p 对 kotlin 开发者有所帮助。

Answer 4

private void callSendMeMail() {
    Intent Email = new Intent(Intent.ACTION_SEND);
    Email.setType("text/email");
    Email.putExtra(Intent.EXTRA_EMAIL, new String[] { "me@gmail.com" });
    Email.putExtra(Intent.EXTRA_SUBJECT, "Feedback");
    startActivity(Intent.createChooser(Email, "Send mail to Developer:"));
}

Answer 5

几件事：

1 - 您需要将操作常量变量设置为 ACTION_SENDTO。
Intent intentEmail = new Intent(Intent.ACTION_SENDTO);

2 - 如果您希望仅通过邮件打开它，请使用 setData() 方法：intentEmail.setData(Uri.parse("mailto:")); 否则它将要求您通过设备上的其他应用程序将其作为文本、图像、音频文件打开。

3 - 您需要将电子邮件 ID 字符串作为 一个数组对象 而不仅仅是一个字符串。字符串为："name@email.com"。字符串的数组对象为：new String[] {"email1", "email2", "more_email"}。

intentEmail.putExtra(Intent.EXTRA_EMAIL, new String[] {"email@overflow.com", "abcd@stack.com"});

Answer 6

这对我有用：

val email = "recipient@email.com"
val intent = Intent(Intent.ACTION_SENDTO)
intent.data = Uri.parse("mailto:$email")
intent.putExtra(Intent.EXTRA_SUBJECT,"My Subject")
startActivity(intent)

Answer 7

让我浪费了这么多时间！感谢接受的答案！ 我将添加一些 Kotlin 代码和几个方便的扩展函数

fun Activity.hasEmailClient(): Boolean =
    emailIntent("someAddress", "someSubject", "someText")
        .resolveActivity(packageManager) != null

fun Activity.openEmailClient(address: String, subject: String, text: String) {
    startActivity(emailIntent(address, subject, text))
}

private fun emailIntent(address: String, subject: String, text: String): Intent =
    Intent(Intent.ACTION_SENDTO).apply {
        type = "text/plain"
        data = Uri.parse("mailto:")
        putExtra(Intent.EXTRA_EMAIL, arrayOf(address))
        putExtra(Intent.EXTRA_SUBJECT, subject)
        putExtra(Intent.EXTRA_TEXT, text)
    }

如果适合您的需要，请随意将 Activity 替换为 Fragment。示例用法：

if (hasEmailClient()) {
    openEmailClient(
        "example@email.info",
        "this is the subject",
        "this is the text"
    )
}

Answer 8

首先您应该将Intent.EXTRA_EMAIL 的值设置为字符串类型，如下所示：

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

如果这不起作用，则只需卸载应用程序并再次运行......
