【Delphi Multi-Device Application】 顯示/隱藏 虛擬鍵盤

 uses FMX.VirtualKeyboard, FMX.Platform;

In the .dpr set VKAutoShowMode to Never

begin
  Application.Initialize;
  VKAutoShowMode := TVKAutoShowMode.Never;
  Application.CreateForm(TForm1, Form1);
  Application.Run;
end. 

Show soft keyboard on the form (for example on TEdit.OnEnter event):

var
  FService: IFMXVirtualKeyboardService;
begin
  TPlatformServices.Current.SupportsPlatformService(IFMXVirtualKeyboardService, IInterface(FService));
  if (FService <> nil) then
  begin
    FService.ShowVirtualKeyboard(Edit1);
    Edit1.SetFocus;
  end;
end;

Hide soft keyboard on the form (Edit1 will be still focused with hidden soft keyboard):

var
  FService: IFMXVirtualKeyboardService;
begin
  TPlatformServices.Current.SupportsPlatformService(IFMXVirtualKeyboardService, IInterface(FService));
  if (FService <> nil) then
  begin
    FService.HideVirtualKeyboard;
    Edit1.SetFocus;
  end;
end;
