Intent.EXTRA_EMAIL未填充"收件人"字段

Question

我试图使用意图从我的应用程序发送电子邮件,但电子邮件的收件人字段将不会填充.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

我想你不及格recipient的array of string

应该是这样的

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

Answer 2

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端

//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)

我希望这段代码片段能够对 kotlin 开发者有所帮助。
