Android layout 如何使选项卡仅对其中一个导航抽屉项可见？

我是android开发的新手，当时正在尝试构建一个带有导航抽屉和选项卡视图的应用程序。我指的是 来构建代码。我设法建立了一个登录页面，这将导致另一个活动页面。在这里，我面临一个问题。我只想要“家”抽屉项目的标签，而不是抽屉项目的其余部分

导航抽屉输出正常

而且它是可点击的。我在网上提到过，但无法缩小范围，找到任何解决方案

activity_main2.xml（选项卡集成和导航抽屉）：

对于代码

这是我的“主”片段xml文件（朋友和消息的格式相同）



这是我的一个xml文件：

     <?xml version="1.0" encoding="utf-8"?>
       <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content"
tools:context="com.example.arunrony.myapplication_trial.OneFragment">
<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="One_tab"
    android:textSize="40dp"
    android:textStyle="bold"
    android:layout_centerInParent="true"/>

      </RelativeLayout>


我忘了添加构建导航抽屉的教程。请帮忙，我真的需要帮忙
