Android 如何在我们的电子邮件中获取联系我们表单的数据

我在android应用程序中创建了一个“联系我们”活动。它包含4个编辑文本，如姓名、电话号码、电子邮件和消息以及提交按钮。我要做的是，当我点击提交按钮时，所有四个编辑文本中的数据都应该通过我的邮件id通过电子邮件发送给我。有人能建议我怎么做吗？如果需要任何进一步的细节，请让我知道。 谢谢 下面是一些代码示例

                String Name = name.getText().toString();
                String Phone = phone.getText().toString();
                String Email = email.getText().toString();
                String Message = message.getText().toString();

                //check whether the msg empty or not
                if (Name.length() != 0 && Phone.length() != 0 && Email.length() != 0) {
                    HttpClient httpclient = new DefaultHttpClient();
                    HttpPost httppost = new HttpPost("http://www.abcd.com/Server1.php");

                    try {
                        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
                        nameValuePairs.add(new BasicNameValuePair("id", "01"));
                        nameValuePairs.add(new BasicNameValuePair("message", Name));

                        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
                        httpclient.execute(httppost);
                        name.setText(""); //reset the message text field
                        phone.setText(""); //reset the message text field
                        email.setText(""); //reset the message text field
                        message.setText(""); //reset the message text field
                        Toast.makeText(getBaseContext(), "Sent", Toast.LENGTH_SHORT).show();
                    } catch (ClientProtocolException e) {
                        e.printStackTrace();
                    } catch (IOException e) {
                        e.printStackTrace();
                    }
                } else {
                    //display message if text field is empty
                    Toast.makeText(getBaseContext(), "All fields are required", Toast.LENGTH_SHORT).show();
                }
            }

您可以找到一个解决方案，用于发送带有意图的电子邮件（需要用户操作）

您必须创建一个

字符串

，其中电子邮件正文包含您要发送的所有数据，然后打开电子邮件客户端，用户可以手动发送消息

否则，您可以使用smtp配置在后台发送电子邮件，而无需按照说明执行用户操作。 这种方式发送电子邮件时用户不知道，但您必须知道电子邮件帐户的配置

我刚刚试着写了一些代码来做到这一点。但它不起作用。请在我写的代码之外再写一些东西。我的目标是在我点击提交按钮时发送邮件id上的所有数据。电子邮件的代码是什么。我的意思是，你能建议一些代码在如果块看看张贴的链接。在那里，您将找到要添加的代码。根据你的需要选择代码，如果你喜欢背景动作或者不喜欢兄弟，你明白我的意思吗？我希望在联系人表单中填写的用户数据应发送到特定的邮件id。因此，谁将是此处的发件人，因为收件人是固定的。您应该传递

电子邮件，而不是
收件人
。我看到的是你正在给“abc@gmail.com".  它应该是这样的：
message.setRecipients（MimeMessage.RecipientType.TO，InternetAddress.parse（Email））如果我误解了你的观点，请告诉我。代码消息.setRecipients（mimessage.RecipientType.TO，InternetAddress.parse（receiver））；已经写好了。我正在从发送数据abc@gmail.com到xyz@gmail.com. 我的观点是，用户将是匿名的。它可以在表单中填写任何数据。当他点击提交按钮时，用户的数据应该在邮件id中接收xyz@gmail.com. 发送者可以是任何人。
