我的表单上有TEdit
和TTMSFMXWebGMaps
。在我的编辑OnKeyUp()
事件中,我有这段代码来隐藏iPhone 4的虚拟键盘:
if TPlatformServices.Current.SupportsPlatformService(IFMXVirtualKeyboardService) then
(TPlatformServices.Current.GetPlatformService(IFMXVirtualKeyboardService) as IFMXVirtualKeyboardService).HideVirtualKeyboard;
问题是,如果不将焦点更改为其他控件,我无法再次显示键盘。我在我的编辑OnTap()
中尝试了这个,但它没有带回键盘:
if TPlatformServices.Current.SupportsPlatformService(IFMXVirtualKeyboardService) then
(TPlatformServices.Current.GetPlatformService(IFMXVirtualKeyboardService) as IFMXVirtualKeyboardService).ShowVirtualKeyboard(edSearch);
由于我的表单只包含一个TEdit
,因此除非用户导航到另一个表单并返回,否则键盘将永远丢失。有什么想法吗?

隐藏虚拟键盘有一种非常简单的方法。
