代号一个showNativePicker未显示 [英] Codename One showNativePicker is not displaying

问题描述

我搜索了一些简单的示例，这些示例使用了没有任何运气的选择器.

I have searched for simple examples of using a picker without any luck.

我想让我的选择器从一组字符串中拉出，以供用户选择，但是我似乎什至无法显示以下内容.

I would like to have my picker pull from a set of strings for the user to choose from, but I can not seem to even get the following to display.

Long now = new Date().getTime();
Date date = (Date) Display.getInstance().showNativePicker(Display.PICKER_TYPE_DATE, cal, now, null);

添加了代码块

推荐答案

您应该使用Picker类而不是直接使用该API.

You should use the Picker class and not that API directly.

本机选择器仅在某些特定类型的选择器中受支持，并且仅在物理Android/iOS设备上受支持. Picker类在不可用时无缝地显示Spinner.

Native picker is only supported for some specific types of picker and only on physical Android/iOS devices. The Picker class seamlessly shows a Spinner instead when unavailable.

要检查是否支持本机选择器，请使用Display.isNativePickerTypeSupported.

To check if the native picker is supported use Display.isNativePickerTypeSupported.
