Android 特定片段中的NavigationDrawer

问题是，我想要我的导航抽屉（汉堡包图标），只出现在某些片段中。在我的例子中，我有三个

片段

，使用

选项卡布局

和

查看页面

在

片段

之间切换。我已经实现了我创建的

接口

。但是当我设置为true时，汉堡图标出现在all

fragment

中。我不知道我的代码哪里出了问题

当我设置此代码时，

（（MainActivity）getActivity（））.setDrawerLocked（true）汉堡图标出现在所有
片段中。但是，当我对其进行注释时，图标不会出现在所有
片段中

以下是XML代码，以防我犯了错误：

只需询问更多详细信息，谢谢。
只需添加选项卡布局更改侦听器并根据需要隐藏和显示图标。
导航处于隐藏模式，请将其更改为可见。。它将在包含碎片的活动中起作用
是的，你有什么推荐网站让我看看这个例子吗？它就像一个符咒一样起作用，我没有想到这一点是多么愚蠢。谢谢这是一个新问题，当我点击汉堡图标时，导航抽屉不会出现。你知道是什么问题吗？导航处于隐藏模式，请将其更改为可见。。行得通。你能解释得更详细些吗？我仍然不明白在标签更改侦听器中，您正在隐藏导航。。。这就是为什么导航没有打开..我应该添加这个
navigationView.setVisibility（View.VISIBLE）对吗？在汉堡图标选项卡中，使导航可见。。。然后它将开始工作是的，在汉堡图标选项卡中添加这一行
