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?

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 :"));
}
});
}

使用这个发送电子邮件…
boolean success = EmailIntentBuilder.from(activity)
.to("support@example.org")
.cc("developer@example.org")
.subject("Error report")
.body(buildErrorReport())
.start();
使用build gradle:
compile 'de.cketti.mailto:email-intent-builder:1.0.0'
Intent emailIntent = new Intent(Intent.ACTION_SENDTO, Uri.fromParts(
"mailto","ebgsoldier@gmail.com", null));
emailIntent.putExtra(Intent.EXTRA_SUBJECT, "Forgot Password");
emailIntent.putExtra(Intent.EXTRA_TEXT, "this is a text ");
startActivity(Intent.createChooser(emailIntent, "Send email..."));
Kotlin版本,只显示电子邮件客户端(没有联系人等):
with(Intent(Intent.ACTION_SEND)) {
type = "message/rfc822"
data = Uri.parse("mailto:")
putExtra(Intent.EXTRA_EMAIL, arrayOf("user@example.com"))
putExtra(Intent.EXTRA_SUBJECT,"YOUR SUBJECT")
putExtra(Intent.EXTRA_TEXT, "YOUR BODY")
try {
startActivity(Intent.createChooser(this, "Send Email with"))
} catch (ex: ActivityNotFoundException) {
// No email clients found, might show Toast here
}
}
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 :"));
}
});
}
下面是在android设备中打开邮件应用程序并在编写邮件时自动填充To address和Subject的示例工作代码。
protected void sendEmail() {
Intent intent = new Intent(Intent.ACTION_SENDTO);
intent.setData(Uri.parse("mailto:feedback@gmail.com"));
intent.putExtra(Intent.EXTRA_SUBJECT, "Feedback");
if (intent.resolveActivity(getPackageManager()) != null) {
startActivity(intent);
}
}
