Question

我正在开发应用程序，其中有一个发送电子邮件的模块。我尝试了很多教程，但电子邮件没有发送，并且没有异常或错误。我正在分享我用来发送电子邮件的所有代码。

final Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);

            emailIntent.setType("plain/text");

            emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, new String[]{ email.getText().toString()});

            emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, name.getText());

            emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, smessage.getText());

          Email.this.startActivity(Intent.createChooser(emailIntent, "Send mail..."));

这个没有用，然后我试过

  Intent emailIntent = new Intent(Intent.ACTION_SENDTO, Uri.fromParts(
                        "mailto","waleedahmed_786@yahoo.com", null));
            emailIntent.putExtra(Intent.EXTRA_SUBJECT, "EXTRA_SUBJECT");
            emailIntent.setTypeAndNormalize("plain/text");
startActivity(Intent.createChooser(emailIntent, "Send email..."));

它也没有奏效。然后我试过

            Intent feedback = new Intent(Intent.ACTION_SEND);
            feedback.putExtra(Intent.EXTRA_EMAIL, new String[]{ to});
              //email.putExtra(Intent.EXTRA_CC, new String[]{ to});
              //email.putExtra(Intent.EXTRA_BCC, new String[]{to});
            feedback.putExtra(Intent.EXTRA_SUBJECT, subject);
            feedback.putExtra(Intent.EXTRA_TEXT, message);

              //need this to prompts email client only
            feedback.setType("text/plain");

              startActivity(Intent.createChooser(feedback, "Choose an Email client :"));

我已经尝试了所有这三个代码，但即使单个代码片段也没有用，我已经在Google nexus上测试但是它无法正常工作

这是我的xml

Answer 1

尝试

Intent send = new Intent(Intent.ACTION_SENDTO);
        String uriText = "mailto:" + Uri.encode("a@b.com") + 
                  "?subject=" + Uri.encode("the subject") + 
                  "&body=" + Uri.encode("the body of the message");
        Uri uri = Uri.parse(uriText);

        send.setData(uri);
        startActivity(Intent.createChooser(send, "Send mail..."));

在Manifest中为Internet访问添加权限。

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

Answer 2

请将类型设置为setType（“application / octet-stream”）而不是plain / text，并且我还要求您确认您的清单文件中是否具有Internet权限。

尝试以下代码片段，其中包含setType ad application / octext-stream，如上所述

//为类意图创建一个对象

Intent sendIntent;

//由于我们要发送，我们正在使用ACTION_SEND

sendIntent = new Intent(Intent.ACTION_SEND);
sendIntent.setType("application/octet-stream");
sendIntent.putExtra(Intent.EXTRA_EMAIL,new String[] {"san123@gmail.com"});
sendIntent.putExtra(Intent.EXTRA_SUBJECT, "Test");
sendIntent.putExtra(Intent.EXTRA_TEXT, "Hy Testing");
sendIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse("file://" + file.getAbsolutePath()));

startActivity(Intent.createChooser(sendIntent, "Send Mail"));

并添加以下权限

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

Answer 3

String to = toEmail.getText().toString();
String subject = emailSubject.getText().toString();
String message = emailBody.getText().toString();
Intent email = new Intent(Intent.ACTION_SEND);
email.putExtra(Intent.EXTRA_EMAIL, new String[] { to });
email.putExtra(Intent.EXTRA_SUBJECT, subject);
email.putExtra(Intent.EXTRA_TEXT, message);
// need this to prompts email client only
email.setType("message/rfc822");
startActivity(Intent.createChooser(email, "Choose an Email client"));
