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，它们工作正常。只有To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...")); }

我正在尝试使用的电子邮件客户端是Gmail

Answer 1

我认为您没有将recipient作为array of string

传递

它应该像

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

Answer 2

使用此

:let new_list=map(copy(list), 'fnamemodify(v:val, ":p:t")')

这会起作用:) 这就是android文档中关于Intent.Extra_Email的说法 - 一个字符串数组全部＆＃34; To＆＃34;收件人电子邮件地址所以你应该正确地输入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或者使用ACTION_SENDTO操作并包含＆＃34; mailto：＆＃34;数据方案。例如：

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...")); 

``}

Answer 3

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 4

事物的结合：

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

2-如果只希望通过邮件打开它，则使用setData（）方法：intentEmail.setData(Uri.parse("mailto:"));否则，它将要求您通过设备上存在的其他应用程序将其作为文本，图像，音频文件打开。 br />

3-您需要将电子邮件ID字符串作为数组对象传递，而不仅仅是字符串。字符串为：“ name@email.com” 。字符串的数组对象是： new String [] {“ email1”，“ email2”，“ more_email”} 。

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

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()
        }
    }

您还可以使用[ 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)

我希望此代码段对kotlin开发人员有所帮助。

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 代码和一些方便的扩展函数

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)
    }

如果它适合您的需要，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"
    )
}

Intent.EXTRA_EMAIL未填充“收件人”字段
