我正在开发一个应用程序在Android。我不知道如何从应用程序发送电子邮件?


当前回答

我很久以前就一直在用这个,看起来不错,没有非电子邮件应用程序显示。这是发送电子邮件意图的另一种方式:

Intent intent = new Intent(Intent.ACTION_SENDTO); // it's not ACTION_SEND
intent.putExtra(Intent.EXTRA_SUBJECT, "Subject of email");
intent.putExtra(Intent.EXTRA_TEXT, "Body of email");
intent.setData(Uri.parse("mailto:default@example.com")); // or just "mailto:" for blank
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); // this will make such that when user returns to your app, your app is displayed, instead of the email app.
startActivity(intent);

简单,试试这个

 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[] { to });
            // email.putExtra(Intent.EXTRA_CC, new String[]{ to});
            // email.putExtra(Intent.EXTRA_BCC, 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 :"));

        }
    });
}

其他解决方案可以是

Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
emailIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
emailIntent.setType("plain/text");
emailIntent.setClassName("com.google.android.gm", "com.google.android.gm.ComposeActivityGmail");
emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, new String[]{"someone@gmail.com"});
emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "Yo");
emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, "Hi");
startActivity(emailIntent);

假设大多数android设备已经安装了GMail应用程序。

我是这么做的。很好很简单。

String emailUrl = "mailto:email@example.com?subject=Subject Text&body=Body Text";
        Intent request = new Intent(Intent.ACTION_VIEW);
        request.setData(Uri.parse(emailUrl));
        startActivity(request);

intent.putExtra(Intent.EXTRA_SUBJECT, "Subject of email");

intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); // this will make such that when user returns to your app, your app is displayed, instead of the email app.
startActivity(intent);
import androidx.core.app.ShareCompat
import androidx.core.content.IntentCompat

ShareCompat.IntentBuilder(this)
                .setType("message/rfc822")
                .setEmailTo(arrayOf(email))
                .setStream(uri)
                .setSubject(subject)
                .setText(message + emailMessage)
                .startChooser()
