Question

我正在从我的应用发送电子邮件意图，通过电子邮件客户端发送邮件。

Intent emailIntent = new Intent(Intent.ACTION_SENDTO, Uri.fromParts("mailto", to[0], null));
                emailIntent.putExtra(Intent.EXTRA_SUBJECT, subject);
                emailIntent.putExtra(Intent.EXTRA_TEXT, body);
                emailIntent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, attachments);

我的附件uri内容：//com.test/logs/test.log

我的意图选择器显示本机Android电子邮件客户端和gmail客户端。

我已经在这里问了我的问题，但没有回复：（

Answer 1

设置你的类型！

Intent emailIntent = new Intent(Intent.ACTION_SEND);
      emailIntent.setData(Uri.parse("mailto:"));
      emailIntent.setType("text/plain");


      emailIntent.putExtra(Intent.EXTRA_EMAIL, TO);
      emailIntent.putExtra(Intent.EXTRA_CC, CC);
      emailIntent.putExtra(Intent.EXTRA_SUBJECT, "Your subject");
      emailIntent.putExtra(Intent.EXTRA_TEXT, "Email message goes here");

我最近发现了一种针对ICS MR1 +的解决方案，同时试图找到一种方法来过滤我的ACTION_SEND_MULTIPLE仅限电子邮件应用。首先，建立你的意图：

sendEmailIntent = new Intent(Intent.ACTION_SEND_MULTIPLE);
sendEmailIntent.setType("message/rfc822");
sendEmailIntent.putExtra(Intent.EXTRA_EMAIL, new String[] { "some@email.com" });                
sendEmailIntent.putExtra(Intent.EXTRA_SUBJECT, "Subject");
sendEmailIntent.putExtra(Intent.EXTRA_TEXT, "Body");
final ArrayList<Uri> uris = /* ... Your code to build the attachments. */
sendEmailIntent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, uris);

然后，如果您需要将其限制为电子邮件应用，请将其限制为：

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.ICE_CREAM_SANDWICH_MR1) {
    sendEmailIntent.setType(null); // If we're using a selector, then clear the type to null. I don't know why this is needed, but it doesn't work without it.
    final Intent restrictIntent = new Intent(Intent.ACTION_SENDTO);
    Uri data = Uri.parse("mailto:?to=some@email.com");
    restrictIntent.setData(data);
    sendEmailIntent.setSelector(restrictIntent);
}

这使您可以通过Gmail发送而不会崩溃。您可能希望在API检查和try / catch中执行startActivity（），并删除选择器＆amp;如果没有找到任何活动，请再试一次。
