使用`mailto:`方案通过意图发送电子邮件附件

Question

我正在使用此代码附加文件:

final Intent emailIntent = new Intent(android.content.Intent.ACTION_SENDTO);
String uriText;
Uri file = Uri.fromFile(new File(path));
uriText = "mailto:" + 
              "?subject=the subject" + 
              "&body=the body of the message"+
              "&attachment="+file;
uriText = uriText.replace(" ", "%20");
Uri uri = Uri.parse(uriText);
emailIntent.setData(uri);
startActivity(Intent.createChooser(emailIntent, "Send mail..."));

(注意,path就像"/sdcard/test.jpg"之类的东西,我ACTION_SENDTO之所以使用,是因为我只想在选择器中看到电子邮件应用程序.)

意图将提供电子邮件应用程序列表,但附件不会出现在电子邮件或Gmail中.如何显示附件？

这种方式对我有用：

public static void sendEmailWithImages(Context context, String emailTo, String emailCC, String subject, String emailText, String type, List<String> filePaths) {
    //need to "send multiple" to get more than one attachment
    final Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND_MULTIPLE);
    emailIntent.setType(type);
    emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, new String[]{emailTo});
    emailIntent.putExtra(android.content.Intent.EXTRA_CC, new String[]{emailCC});
    emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, subject);
    emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, emailText);
    //has to be an ArrayList
    ArrayList<Uri> uris = new ArrayList<Uri>();
    //convert from paths to Android friendly Parcelable Uri's
    if(filePaths != null) {
        for (String file : filePaths) {
            File fileIn = new File(file);
            Uri u = Uri.fromFile(fileIn);
            uris.add(u);
        }
        emailIntent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, uris);
    }
    try {
        context.startActivity(Intent.createChooser(emailIntent, context.getString(R.string.send_email_using_message)));
    }catch (ActivityNotFoundException e) {
        //TODO
    }
}
