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
我在我的应用程序中使用下面的代码。这显示准确的电子邮件客户端应用程序,如Gmail。
Intent contactIntent = new Intent(Intent.ACTION_SENDTO, Uri.fromParts("mailto", getString(R.string.email_to), null));
contactIntent.putExtra(Intent.EXTRA_SUBJECT, getString(R.string.email_subject));
startActivity(Intent.createChooser(contactIntent, getString(R.string.email_chooser)));

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);
}
}
}
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..."));
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 :"));
}
});
}

if (pm != null) {
try {
pm.getPackageInfo(packageName, 0);
return true;
} catch (PackageManager.NameNotFoundException e) {
e.printStackTrace();
}
}
return false;
