菜单 - ＆gt;子菜单 - ＆gt;幻灯片抽屉菜单中的子菜单是否可以在android中？

Question

我正在尝试在Android中使用这种格式Menu->submenu->submenu创建一个幻灯片抽屉菜单，但它不起作用，如果可能的话，我还需要如何设置最终子菜单onclick事件。

请帮助我，我需要这个，并在一个月内冲浪，但仍然没有得出任何结论。

请给我一些关于这个概念的想法

我的个人经历

当我第一次学习Android时，我认为它很棒，因为它非常简单。您可以在线找到几乎任何问题的答案。

现在，我感觉不一样。因为我们在我的工作场所在Android中编写了一个复杂的工程工具，所以我们必须进行大量的自定义UI编程。这不好玩。这是一层地狱。 Android是一个痛苦的做自定义编码。

现在，这就是说。我会主张你坚持使用current Android standard。之后，你有一些选择。以下是我们所做的两个例子：

1. ＆＃39;关于＆＃39; - 在页面的顶部，我们有一个带有子菜单项的微调器的小片段。这些包括＆＃39;关于我们＆＃39; ＆＃39;更新日志＆＃39; ＆＃39;隐私政策＆＃39;等
2. ＆＃39;帮助＆＃39; - 整个页面都填充了所有子菜单项的Listview（每个帮助主题一个）。当您点击某个主题时，它会打开一个新片段，显示“之前的”字样。和＆＃39; next＆＃39;周围主题的按钮。

探索您的选择。如果您一直在寻找这个解决方案的数月，那么可能是时候灵活应对您的愿望了。

找到更好的方法来整理您的信息

请记住（取决于您的实施方式），导航复杂的菜单可能会很复杂且令人迷茫。尝试通过尽可能少的级别使用户尽可能轻松。查看显示different ways to organize complex navigation on a web page的网站。您可能会在移动设备上获得一些想法。 （提示：Listviews允许您将不可点击的标题作为项目...）以下是具有one sub-menu的应用的示例。做一些更多的研究，以便您确切地知道您想要实施什么以及如何实施。然后...

编写自定义控件

Android做得对的一件事是他们确实提供了有用的文档：Creating Custom Views。您可以扩展DrawerLayout控件以处理多个列表视图，或基本上您想要的任何内容。

祝你好运！
