我正在将一个TEXT文件附加到电子邮件中，代码为：
Intent emailIntent = new Intent(Intent.ACTION_SENDTO, Uri.fromParts("mailto",
"abc@gmail.com", null));
emailIntent.putExtra(Intent.EXTRA_SUBJECT, "Report");
emailIntent.putExtra(Intent.EXTRA_TEXT, prepareBodyMail());
File root = Environment.getExternalStorageDirectory();
File file = new File(root, "/MyFolder/report.txt");
Uri uri = Uri.fromFile(file);
emailIntent.putExtra(Intent.EXTRA_STREAM, uri);
startActivity(Intent.createChooser(emailIntent, "Pick an Email provider"));
此代码与Gmail、电子邮件和其他应用程序完美配合
但这并不是谷歌使用INBOX应用程序附加文件
只有身体和受试者没有任何附件
我已经在收件箱问题向谷歌小组报告了这个问题
有人能帮我解决代码中缺少的问题吗？
在Kotlin 中
fun Context.shareAttachmentsToMail(mailId: String?, uri: Uri, subject: String, bodyMessage: String){
val selectorIntent = Intent(ACTION_SENDTO).apply {
data = Uri.parse("mailto:")
}
val emailIntent = Intent(ACTION_SEND).apply {
putExtra(Intent.EXTRA_EMAIL, arrayOf(mailId))
putExtra(Intent.EXTRA_SUBJECT, subject)
putExtra(Intent.EXTRA_TEXT, bodyMsg)
putExtra(Intent.EXTRA_STREAM, uri)
selector = selectorIntent
}
try {
startActivity(Intent.createChooser(emailIntent, ""))
} catch (e: ActivityNotFoundException) {
// Application not found
}
}
这样调用这个扩展函数：
requireContext().shareAttachmentsToMail(mailId = mailId, uri = uri, subject = "your subject", bodyMessage = "your body message")
String fileLocation = Environment.getExternalStorageDirectory() + "/MyFolder/report.txt";
String to[] = {"abc@gmail.com"};
Intent intentEmail = new Intent(Intent.ACTION_SEND);
intentEmail.setType("vnd.android.cursor.dir/email");
intentEmail.putExtra(Intent.EXTRA_EMAIL, to);
intentEmail.putExtra(Intent.EXTRA_STREAM, fileLocation);
intentEmail.putExtra(Intent.EXTRA_SUBJECT, "Subject");
startActivity(Intent.createChooser(intentEmail , "Pick an Email provider"));
试试这个
Uri myUri = Uri.parse("file://" + path);
emailIntent.putExtra(Intent.EXTRA_STREAM, myUri);
Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("text/plain");
intent.putExtra(Intent.EXTRA_EMAIL, new String[] {"email@example.com"});
intent.putExtra(Intent.EXTRA_SUBJECT, "subject here");
intent.putExtra(Intent.EXTRA_TEXT, "body text");
File root = Environment.getExternalStorageDirectory();
File file = new File(root, xmlFilename);
if (!file.exists() || !file.canRead()) {
Toast.makeText(this, "Attachment Error", Toast.LENGTH_SHORT).show();
finish();
return;
}
Uri uri = Uri.fromFile("file://" + file);
intent.putExtra(Intent.EXTRA_STREAM, uri);
startActivity(Intent.createChooser(intent, "Send email..."));
public void sendMailWithIntent(String emailTo,
String subject, String emailText, List<String> filePaths) {
try {
//need to "send multiple" to get more than one attachment
final Intent emailIntent = new Intent(Intent.ACTION_SEND_MULTIPLE);
emailIntent.setType("text/plain");
emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL,
Util.extractEmails(emailTo));
// emailIntent.putExtra(android.content.Intent.EXTRA_CC,
// new String[]{emailCC});
emailIntent.putExtra(Intent.EXTRA_SUBJECT, subject);
emailIntent.putExtra(Intent.EXTRA_TEXT, emailText);
ArrayList<Uri> uris = new ArrayList<Uri>();
//has to be an ArrayList
if (filePaths != null) {
//convert from paths to Android friendly Parcelable Uri's
for (String file : filePaths) {
File fileIn = new File(file);
Uri u = Uri.fromFile(fileIn);
uris.add(u);
}
}
emailIntent.putParcelableArrayListExtra(Intent.EXTRA_STREAM, uris);
Intent chooser = Intent.createChooser(emailIntent, "Send mail...");
activity.startActivityForResult(chooser, 1);
} catch (Exception e) {
new ShowToast(context, e.getMessage());
}
}
调用方法
List<String> list = new ArrayList<>();
list.add(TO_ATTACH_ONE);
list.add(TO_ATTACH_TWO);
sendMailWithIntent(toAddresses, subject, body, list);
ACTION_SENDTO似乎不正式支持附件。它只适用于Gmail和默认的电子邮件客户端，因为它们使用"未记录"功能。我发现发送带有附件的电子邮件的唯一方法是使用ACTION_send。
我的解决方案：
public class EmailSender {
private static final String INTENT_DATA_SCHEME_EMAIL = "mailto:";
private static final String FILE_PROVIDER_AUTHORIZER = "com.smartinhalerlive.app.fileprovider";
private String subject;
private String body;
private File attachment;
public EmailSender(String subject, String body, File attachment) {
this.subject = subject;
this.body = body;
this.attachment = attachment;
}
public void sendEmail(Context context, EmailSenderListener listener) {
List<ResolveInfo> emailClients = getEmailClients(context);
if (null != emailClients) {
ResolveInfo defaultEmailClient = getDefaultEmailClient(emailClients);
if (null != defaultEmailClient) {
sendEmailUsingSelectedEmailClient(context, defaultEmailClient, listener);
} else {
showSelectEmailClientsDialog(context, emailClients, listener);
}
}
}
private void showSelectEmailClientsDialog(Context context,
List<ResolveInfo> emailClients,
EmailSenderListener listener) {
String[] emailClientNames = getEmailClientNames(context, emailClients);
AlertDialog.Builder builder = new AlertDialog.Builder(context);
builder.setTitle(R.string.email_dialog_title);
builder.setItems(emailClientNames, (dialog, which) -> {
sendEmailUsingSelectedEmailClient(context, emailClients.get(which), listener);
}
);
builder.create().show();
}
