使用我在another post上找到的代码,电子邮件似乎已准备好与附件一起发送,但收到电子邮件时,没有附件。此外,必须手动输入电子邮件地址,CreateEmail语句不会填充该地址。我是从一个Gmail帐户发送的。有人帮忙吗?
procedure TForm1.CreateEmail(const Recipient, Subject, Content,
Attachment: string);
var
Intent: JIntent;
Uri: Jnet_Uri;
AttachmentFile: JFile;
begin
Intent := TJIntent.Create;
Intent.setAction(TJIntent.JavaClass.ACTION_SEND);
Intent.setFlags(TJIntent.JavaClass.FLAG_ACTIVITY_NEW_TASK);
Intent.putExtra(TJIntent.JavaClass.EXTRA_EMAIL, StringToJString(Recipient));
Intent.putExtra(TJIntent.JavaClass.EXTRA_SUBJECT, StringToJString(Subject));
Intent.putExtra(TJIntent.JavaClass.EXTRA_TEXT, StringToJString(Content));
AttachmentFile := SharedActivity.getExternalFilesDir
(StringToJString(Attachment));
Uri := TJnet_Uri.JavaClass.fromFile(AttachmentFile);
Intent.putExtra(TJIntent.JavaClass.EXTRA_STREAM,
TJParcelable.Wrap((Uri as ILocalObject).GetObjectID));
Intent.setType(StringToJString('vnd.android.cursor.dir/email'));
SharedActivity.startActivity(Intent);
end;
procedure TForm1.Button1Click(Sender: TObject);
begin
CreateEmail('xxx@shaw.ca', 'Test Results', Memo1.Lines.text,'/sdcard/Download/Demo.pdf');
end;

Intent.EXTRA_EMAIL
为documented,因为期待数组字符串值,但您传递的是单个字符串。
您还没有正确使用SharedActivity.getExternalFilesDir()
。其type
参数指定要查找的文件夹类型(MUSIC
,PODCASTS
,PICTURES
等),然后返回表示文件夹的JFile
。然后,您可以根据需要将文件名附加到该文件夹的路径。但是,在这种情况下,您的Attachment
字符串包含要附加的实际文件的完整路径,因此您根本不应该调用getExternalFilesDir()
。而是按原样从路径创建JFile
。
试试这个:
procedure TForm1.CreateEmail(const Recipient, Subject, Content, Attachment: string);
var
JRecipient: TJavaObjectArray<JString>;
Intent: JIntent;
Uri: Jnet_Uri;
AttachmentFile: JFile;
begin
JRecipient := TJavaObjectArray<JString>.Create(1);
JRecipient.Items[0] := StringToJString(Recipient);
Intent := TJIntent.Create;
Intent.setAction(TJIntent.JavaClass.ACTION_SEND);
Intent.setFlags(TJIntent.JavaClass.FLAG_ACTIVITY_NEW_TASK);
Intent.putExtra(TJIntent.JavaClass.EXTRA_EMAIL, JRecipient);
Intent.putExtra(TJIntent.JavaClass.EXTRA_SUBJECT, StringToJString(Subject));
Intent.putExtra(TJIntent.JavaClass.EXTRA_TEXT, StringToJString(Content));
if Attachment <> '' then
begin
AttachmentFile := TJFile.JavaClass.init(StringToJString(Attachment));
Uri := TJnet_Uri.JavaClass.fromFile(AttachmentFile);
Intent.putExtra(TJIntent.JavaClass.EXTRA_STREAM, TJParcelable.Wrap((Uri as ILocalObject).GetObjectID));
end;
Intent.setType(StringToJString('vnd.android.cursor.dir/email'));
SharedActivity.startActivity(Intent);
end;

以下是多个附件的工作代码。适用于10.1柏林。
procedure TForm1.ItemShare;
var
chooserIntent, Intent: JIntent;
Uri: Jnet_Uri;
Uris: JArrayList;
AttachmentFile: JFile;
begin
{$IFDEF ANDROID}
intent := TJIntent.Create;
intent.setAction(TJIntent.JavaClass.ACTION_SEND_MULTIPLE);
intent.setType(StringToJString('text/*'));
intent.putExtra(TJIntent.JavaClass.EXTRA_SUBJECT, StringToJString('Email header'));
Uris:= TJArrayList.Create;
while i<condition
begin
AttachmentFile := TJFile.JavaClass.init(StringToJString('filename'));
Uri := TJnet_Uri.JavaClass.fromFile(AttachmentFile);
Uris.add(i,Uri);
inc(i);
end;
Intent.putParcelableArrayListExtra(TJIntent.JavaClass.EXTRA_STREAM, Uris);
Intent.putExtra(TJIntent.JavaClass.EXTRA_TEXT, StringToJString('body'));
chooserIntent := TJIntent.JavaClass.createChooser(Intent, StrToJCharSequence('Share using'));
TAndroidHelper.Activity.startActivityForResult(chooserIntent, 0);
{$ENDIF}
end;
