发送电子邮件

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

Intent emailIntent = new Intent(Intent.ACTION_SENDTO, Uri.fromParts("mailto", email, null));
if (emailIntent.resolveActivity(context.getPackageManager()) != null) {
    context.startActivity(Intent.createChooser(emailIntent, "Send Email..."));
} else {
    Toast.makeText(context, "No apps can perform this action.", Toast.LENGTH_SHORT).show();
}

其他回答

用Anko - kotlin

context.email(email, subject, body)

也许你应该试试这个:intent.setType("plain/text");

我在这里找到的。我在我的应用程序中使用过它，它只显示电子邮件和Gmail选项。

编辑:不再工作与Gmail的新版本

这是我当时发现的唯一方法，让它与任何角色一起工作。

doreamon的答案是正确的，因为它适用于Gmail新版本的所有角色。

旧的回答:

这是我的。它似乎适用于所有Android版本，支持主题和消息体，并支持完整的utf-8字符:

public static void email(Context context, String to, String subject, String body) {
    StringBuilder builder = new StringBuilder("mailto:" + Uri.encode(to));
    if (subject != null) {
        builder.append("?subject=" + Uri.encode(Uri.encode(subject)));
        if (body != null) {
            builder.append("&body=" + Uri.encode(Uri.encode(body)));
        }
    }
    String uri = builder.toString();
    Intent intent = new Intent(Intent.ACTION_SENDTO, Uri.parse(uri));
    context.startActivity(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
}

适用于所有android版本:

String[] to = {"email@server.com"};
Uri uri = Uri.parse("mailto:email@server.com")
  .buildUpon()
  .appendQueryParameter("subject", "subject")
  .appendQueryParameter("body", "body")
  .build();
Intent emailIntent = new Intent(ACTION_SENDTO, uri);
emailIntent.putExtra(EXTRA_EMAIL, TO);
startActivity(Intent.createChooser(emailIntent, "Send mail..."));

更新到Android 10，现在使用Kotlin…

fun Context.sendEmail(
  address: String?,
  subject: String?,
  body: String?,
) {
  val recipients = arrayOf(address)
  val uri = address.toUri()
    .buildUpon()
    .appendQueryParameter("subject", subject)
    .appendQueryParameter("body", body)
    .build()
  val emailIntent = Intent(ACTION_SENDTO, uri).apply {
    setData("mailto:$address".toUri());
    putExtra(EXTRA_SUBJECT, subject);
    putExtra(EXTRA_TEXT, body);
    putExtra(EXTRA_EMAIL, recipients)
  }
  val pickerTitle = getString(R.string.some_title)
  ContextCompat.startActivity(this, Intent.createChooser(emailIntent, pickerTitle, null)
}

.．.在更新到API 30之后，代码没有填充电子邮件客户端的主题和主体(例如Gmail)。但我在这里找到了答案:

fun Context.sendEmail(
  address: String?,
  subject: String?,
  body: String?,
) {
  val selectorIntent = Intent(ACTION_SENDTO)
    .setData("mailto:$address".toUri())
  val emailIntent = Intent(ACTION_SEND).apply {
    putExtra(EXTRA_EMAIL, arrayOf(address))
    putExtra(EXTRA_SUBJECT, subject)
    putExtra(EXTRA_TEXT, body)
    selector = selectorIntent
  }
  startActivity(Intent.createChooser(emailIntent, getString(R.string.send_email))) 

}
