Question

我在Android应用程序中创建了一个与我们联系的活动。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，所有四个编辑文本的数据应该通过我的邮件ID通过电子邮件发送给我。任何人都可以建议我该怎么办？如果需要任何进一步的细节，请告诉我。谢谢这是一些代码示例。

myFile=open(cases2.json, 'r')
myObject=myFile.read()
u = myObject.decode('utf-8-sig')
myObject = u.encode('utf-8')
myFile.encoding
myFile.close()
myData=json.loads(myObject,'utf-8')

我写了这段代码。它没有给出任何错误。应用程序也没有崩溃，但数据没有收到电子邮件。任何帮助？

                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();
                }
            }

Here您可以找到一个有意图发送电子邮件的解决方案（需要用户操作）。

您必须使用包含您要发送的所有数据的电子邮件正文创建String，然后打开电子邮件客户端，用户可以手动发送该邮件。

否则，您可以使用smtp配置在后台发送电子邮件，而无需用户操作，如here所述。这样，电子邮件在用户不知情的情况下发送，但您必须知道电子邮件帐户的配置。
