Question

我有以下代码，它只是打开我的gmail的邮件发送屏幕，我不希望这样。实际上我想在onClick期间将即时邮件发送到mail-id。可能吗？请帮助。谢谢。我需要添加任何权限吗？

package com.example.emails;
    import android.os.Bundle;
    import android.app.Activity;
    import android.content.Intent;
    import android.view.Menu;
    import android.view.View;
    import android.view.View.OnClickListener;
    import android.widget.Button;

    public class Emails extends Activity {
        private static Button email;
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_emails);

           email= (Button)findViewById(R.id.button1);
           email.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub


                Intent email = new Intent(Intent.ACTION_SEND);
                  email.putExtra(Intent.EXTRA_EMAIL, new String[]{ "arunshankar.certify@gmail.com"});
                  //email.putExtra(Intent.EXTRA_CC, new String[]{ to});
                  //email.putExtra(Intent.EXTRA_BCC, new String[]{to});
                  email.putExtra(Intent.EXTRA_SUBJECT, "new mail");
                  email.putExtra(Intent.EXTRA_TEXT, "hello");

                  //need this to prompts email client only
                  email.setType("message/rfc822");

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


        @Override
        public boolean onCreateOptionsMenu(Menu menu) {
            // Inflate the menu; this adds items to the action bar if it is present.
            getMenuInflater().inflate(R.menu.emails, menu);
            return true;
        }

    }

Answer 1

是的，有可能。但是你需要一个能够发送电子邮件的服务器。设备将对此服务器发出HTTP POST请求，并传递需要发送的参数。

Answer 2

您可以使用JAVA邮件API发送邮件而无需设置意图。请按照 https://code.google.com/p/javamail-android/

进行操作

Answer 3

试试这个

Intent intent = new Intent(Intent.ACTION_SEND);
                intent.setType("plain/text");
                intent.putExtra(android.content.Intent.EXTRA_EMAIL,
                        new String[] { "your email" });
                startActivity(Intent.createChooser(intent, ""));
