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
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。

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'
为了让电子邮件应用程序来解决你的意图,你需要指定ACTION_SENDTO作为动作和mailto作为数据。
private void sendEmail(){
Intent emailIntent = new Intent(Intent.ACTION_SENDTO);
emailIntent.setData(Uri.parse("mailto:" + "recipient@example.com")); // You can use "mailto:" if you don't know the address beforehand.
emailIntent.putExtra(Intent.EXTRA_SUBJECT, "My email's subject");
emailIntent.putExtra(Intent.EXTRA_TEXT, "My email's body");
try {
startActivity(Intent.createChooser(emailIntent, "Send email using..."));
} catch (android.content.ActivityNotFoundException ex) {
Toast.makeText(Activity.this, "No email clients installed.", Toast.LENGTH_SHORT).show();
}
}
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()
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);
}
}
}
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);
}
}
