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?

这个函数首先直接意图gmail发送电子邮件,如果gmail没有找到,然后提升意图选择器。我在许多商业应用程序中使用了这个功能,它工作得很好。希望对你有所帮助:
public static void sentEmail(Context mContext, String[] addresses, String subject, String body) {
try {
Intent sendIntentGmail = new Intent(Intent.ACTION_VIEW);
sendIntentGmail.setType("plain/text");
sendIntentGmail.setData(Uri.parse(TextUtils.join(",", addresses)));
sendIntentGmail.setClassName("com.google.android.gm", "com.google.android.gm.ComposeActivityGmail");
sendIntentGmail.putExtra(Intent.EXTRA_EMAIL, addresses);
if (subject != null) sendIntentGmail.putExtra(Intent.EXTRA_SUBJECT, subject);
if (body != null) sendIntentGmail.putExtra(Intent.EXTRA_TEXT, body);
mContext.startActivity(sendIntentGmail);
} catch (Exception e) {
//When Gmail App is not installed or disable
Intent sendIntentIfGmailFail = new Intent(Intent.ACTION_SEND);
sendIntentIfGmailFail.setType("*/*");
sendIntentIfGmailFail.putExtra(Intent.EXTRA_EMAIL, addresses);
if (subject != null) sendIntentIfGmailFail.putExtra(Intent.EXTRA_SUBJECT, subject);
if (body != null) sendIntentIfGmailFail.putExtra(Intent.EXTRA_TEXT, body);
if (sendIntentIfGmailFail.resolveActivity(mContext.getPackageManager()) != null) {
mContext.startActivity(sendIntentIfGmailFail);
}
}
}

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 :"));
}
});
}
使用. settype ("message/rfc822")或者选择器会显示所有(许多)支持发送意图的应用程序。
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。
这将只显示您的电子邮件客户端(以及PayPal出于某些未知的原因)
public void composeEmail() {
Intent intent = new Intent(Intent.ACTION_SENDTO);
intent.setData(Uri.parse("mailto:"));
intent.putExtra(Intent.EXTRA_EMAIL, new String[]{"hi@example.com"});
intent.putExtra(Intent.EXTRA_SUBJECT, "Subject");
intent.putExtra(Intent.EXTRA_TEXT, "Body");
try {
startActivity(Intent.createChooser(intent, "Send mail..."));
} catch (android.content.ActivityNotFoundException ex) {
Toast.makeText(MainActivity.this, "There are no email clients installed.", Toast.LENGTH_SHORT).show();
}
}
