Java 如何向特定的邮件id发送电子邮件？

我正在开发的联系方式，需要发送电子邮件到特定的邮件id是固定的…请帮助我

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    buttonSend = (Button) findViewById(R.id.buttonSend);
    textTo = (EditText) findViewById(R.id.editTextTo);
    textSubject = (EditText) findViewById(R.id.editTextSubject);
    textMessage = (EditText) findViewById(R.id.editTextMessage);

    buttonSend.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {

            String to = textTo.getText().toString();
            String subject = textSubject.getText().toString();
            String message = textMessage.getText().toString();
            Intent email = new Intent(Intent.ACTION_SEND);
            email.putExtra(Intent.EXTRA_EMAIL, new String[]{"abcdk@gmail.com"});          
            email.putExtra(Intent.EXTRA_SUBJECT, "subject");
            email.putExtra(Intent.EXTRA_TEXT, "message");
            email.setType("text/plain");
            startActivity(Intent.createChooser(email, "Choose an Email client :"));


        }
    });

但它不起作用

对于已发送的邮件，请使用以下代码

final Intent emailIntent = new Intent(
                    android.content.Intent.ACTION_SEND);
            emailIntent.setType("plain/text");
            emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL,
                    new String[] { vendoremail });
            emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT,
                    _productList.get(0).ProductName);

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

这里

vendoremail=电子邮件id， _productList.get0.ProductName=电子邮件说明

编辑：

您必须在AndroidManifest.xml文件中授予权限

最好且最简单的方法是使用意图：

Intent i = new Intent(Intent.ACTION_SEND);
i.setType("message/rfc822");
i.putExtra(Intent.EXTRA_EMAIL  , new String[]{"recipient@example.com"});
i.putExtra(Intent.EXTRA_SUBJECT, "subject of email");
i.putExtra(Intent.EXTRA_TEXT   , "body of email");
try {
    startActivity(Intent.createChooser(i, "Send mail..."));
} catch (android.content.ActivityNotFoundException ex) {
    Toast.makeText(MyActivity.this, "There are no email clients installed.", Toast.LENGTH_SHORT).show();
}

否则，您必须编写自己的客户端。

更改setType

用这条线

email.setType("message/rfc822");

而不是

email.setType("text/plain");

试试这个

Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
emailIntent .setType("text/plain");
emailIntent .putExtra(Intent.EXTRA_EMAIL  , new String[]{"recipientemail@example.com"});
emailIntent .putExtra(Intent.EXTRA_SUBJECT, "subject");
emailIntent .putExtra(Intent.EXTRA_TEXT   , "body");
startActivity(Intent.createChooser(emailIntent , "Email:"));

或者你可以访问这个链接，你在emulator中测试它吗？不，我使用的是android设备。我使用了你的代码，但它仍然没有发送任何邮件。请帮助我处理我的问题。您是否授予了所有必要的权限？答案中添加了权限。@Hardy:谢谢，但它会重定向到撰写邮件，我的要求是“联系我们”表单中有字段，请直接将详细信息发送到id…请帮助我…此代码在我的情况下运行良好。检查您是否已在电子邮件客户端中设置了电子邮件帐户，您正在使用该电子邮件客户端处理应用程序的意图。

Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
emailIntent .setType("text/plain");
emailIntent .putExtra(Intent.EXTRA_EMAIL  , new String[]{"recipientemail@example.com"});
emailIntent .putExtra(Intent.EXTRA_SUBJECT, "subject");
emailIntent .putExtra(Intent.EXTRA_TEXT   , "body");
startActivity(Intent.createChooser(emailIntent , "Email:"));
