Navigation 导航抽屉不工作无法移动到fragmets

我正在开发一个在线购物应用程序。我使用了导航抽屉活动，但它根本不适用于eg

如果我想从主片段移动到gallery片段，它不会移动（单击不起作用），并且我无法确定是否删除了一些重要的行或者问题出在哪里。
有人能提出一些建议吗

以下是我的主要活动的样子：

有人能建议我可以做些什么或改变什么来启用它吗？

什么是“根本不工作”？它有什么作用？你期望它做什么？你是否错过了语言标签？我无法移动到其他片段，例如。如果我在home fragment中，想进入Gallery fragment或任何其他片段，我单击抽屉上的该选项，它不会移动。我的意思是让你将其编辑到你的问题中。“根本不工作”是什么意思？它有什么作用？你期望它做什么？你是否错过了语言标签？我无法移动到其他片段，例如。如果我在home fragment中，想转到Gallery fragment或任何其他片段，我单击抽屉上的该选项，它不会移动。我的意思是让你将其编辑到你的问题中。
