Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("text/html");
intent.putExtra(Intent.EXTRA_EMAIL, "emailaddress@emailaddress.com");
intent.putExtra(Intent.EXTRA_SUBJECT, "Subject");
intent.putExtra(Intent.EXTRA_TEXT, "I'm email body.");
startActivity(Intent.createChooser(intent, "Send Email"));

上面的代码打开一个对话框,显示以下应用程序:-蓝牙,谷歌文档,雅虎邮件,Gmail, Orkut, Skype等。

实际上,我想过滤这些列表选项。我只想显示电子邮件相关的应用程序,如Gmail和雅虎邮件。怎么做呢?

我曾在Android Market应用中看到过这样的例子。

打开Android Market应用程序 打开任何开发者指定了他/她的电子邮件地址的应用程序。(如果你找不到这样的应用程序,请打开我的应用程序:- market://details?id=com.becomputer06.vehicle.diary.free,或通过“车辆日记”搜索) 向下滚动到“开发者” 点击“发送电子邮件”

对话框只显示电子邮件应用程序,如Gmail,雅虎邮件等。它不显示蓝牙,Orkut等。什么样的代码产生这样的对话?


当前回答

下面的代码对我来说很好。

Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("message/rfc822");
intent.putExtra(Intent.EXTRA_SUBJECT, subject);
intent.putExtra(Intent.EXTRA_EMAIL, new String[]{"abc@gmailcom"});
Intent mailer = Intent.createChooser(intent, null);
startActivity(mailer);

如果您想要以Gmail为目标,那么您可以执行以下操作。注意,意图是“ACTION_SENDTO”而不是“ACTION_SEND”,额外的意图字段对于Gmail是不必要的。

String uriText =
    "mailto:youremail@gmail.com" + 
    "?subject=" + Uri.encode("your subject line here") + 
    "&body=" + Uri.encode("message body here");

Uri uri = Uri.parse(uriText);

Intent sendIntent = new Intent(Intent.ACTION_SENDTO);
sendIntent.setData(uri);
if (sendIntent.resolveActivity(getPackageManager()) != null) {
   startActivity(Intent.createChooser(sendIntent, "Send message")); 
}

这对我来说非常有效:

    Intent intent = new Intent(Intent.ACTION_VIEW);
    intent.setData(Uri.parse("mailto:" + address));
    startActivity(Intent.createChooser(intent, "E-mail"));

在电话邮件客户端撰写邮件:

Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("plain/text");
intent.putExtra(Intent.EXTRA_EMAIL, new String[] { "some@email.address" });
intent.putExtra(Intent.EXTRA_SUBJECT, "subject");
intent.putExtra(Intent.EXTRA_TEXT, "mail body");
startActivity(Intent.createChooser(intent, ""));

这些答案大多只适用于不发送附件的简单情况。在我的情况下,我有时需要发送附件(ACTION_SEND)或两个附件(ACTION_SEND_MULTIPLE)。

所以我从这条线索中选择了最好的方法并将它们结合起来。它使用支持库的ShareCompat。但是我只展示了匹配ACTION_SENDTO和"mailto:" uri的应用程序。这样我得到的只有附件支持的电子邮件应用程序列表:

fun Activity.sendEmail(recipients: List<String>, subject: String, file: Uri, text: String? = null, secondFile: Uri? = null) {
    val originalIntent = createEmailShareIntent(recipients, subject, file, text, secondFile)
    val emailFilterIntent = Intent(Intent.ACTION_SENDTO, Uri.parse("mailto:"))
    val originalIntentResults = packageManager.queryIntentActivities(originalIntent, 0)
    val emailFilterIntentResults = packageManager.queryIntentActivities(emailFilterIntent, 0)
    val targetedIntents = originalIntentResults
            .filter { originalResult -> emailFilterIntentResults.any { originalResult.activityInfo.packageName == it.activityInfo.packageName } }
            .map {
                createEmailShareIntent(recipients, subject, file, text, secondFile).apply { `package` = it.activityInfo.packageName }
            }
            .toMutableList()
    val finalIntent = Intent.createChooser(targetedIntents.removeAt(0), R.string.choose_email_app.toText())
    finalIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, targetedIntents.toTypedArray())
    startActivity(finalIntent)
}

private fun Activity.createEmailShareIntent(recipients: List<String>, subject: String, file: Uri, text: String? = null, secondFile: Uri? = null): Intent {
    val builder = ShareCompat.IntentBuilder.from(this)
            .setType("message/rfc822")
            .setEmailTo(recipients.toTypedArray())
            .setStream(file)
            .setSubject(subject)
    if (secondFile != null) {
        builder.addStream(secondFile)
    }
    if (text != null) {
        builder.setText(text)
    }
    return builder.intent
}

如果你想确保你的意图只被电子邮件应用程序处理(而不是其他短信或社交应用程序),那么使用ACTION_SENDTO动作并包括“mailto:”数据方案。例如:

public void composeEmail(String[] addresses, String subject) {
    Intent intent = new Intent(Intent.ACTION_SENDTO);
    intent.setData(Uri.parse("mailto:")); // only email apps should handle this
    intent.putExtra(Intent.EXTRA_EMAIL, addresses);
    intent.putExtra(Intent.EXTRA_SUBJECT, subject);
    if (intent.resolveActivity(getPackageManager()) != null) {
        startActivity(intent);
    }
}
