email - 发送邮件 : Intent. EXTRA_EMAIL 不起作用

Question

我没有收到任何错误，但不会显示邮件收件人!它保持空白

public void Send_Mail(View view) {
        String txt_context = "My comment about the App : \n The App is good but does not support v3";
        Intent intent = new Intent(Intent.ACTION_SEND);
        intent.setData(Uri.parse("mailto:"));
        intent.setType("message/rfc822"); // 
        intent.putExtra(Intent.EXTRA_EMAIL,"receiver@gmail.com"); // **this will not displayed** """
        intent.putExtra(Intent.EXTRA_SUBJECT,"Comment about the APP");
        intent.putExtra(Intent.EXTRA_TEXT,txt_context);
        startActivity(intent);

Answer 1

我知道这篇文章很旧，但我遇到了同样的问题，我找到了解决方案( in the official documentation ):

正如所解释的，Intent.EXTRA_EMAIL是:

A String[] holding e-mail addresses that should be delivered to.

因此，要解决您的问题，而不是:

intent.putExtra(Intent.EXTRA_EMAIL,"receiver@gmail.com");

做:

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