android:id="@+id/main"

    android:name="com.poultry.poultryscope.HomeFragment"
    android:label="Home"

    <action
        android:id="@+id/action_menuhome_to_menudiseases"
        app:destination="@id/menudiseases" />
    <action
        android:id="@+id/action_menuhome_to_menuDoseCalculator"
        app:destination="@id/menuDoseCalculator" />
    <action
        android:id="@+id/action_menuhome_to_menuReferences"
        app:destination="@id/menuReferences" />
</fragment>

<fragment
    android:id="@+id/menudiseases"
    android:name="com.poultry.poultryscope.DiseasesFragment"
    android:label="@string/diseases"
    tools:layout="@layout/fragment_diseases" />

<fragment
    android:id="@+id/menuDrugs"
    android:name="com.poultry.poultryscope.DrugsFragment"
    android:label="@string/drugs"
    tools:layout="@layout/fragment_drugs" />

<fragment
    android:id="@+id/menuDoseCalculator"
    android:name="com.poultry.poultryscope.DoseCalculatorFragment"
    android:label="@string/DC"
    tools:layout="@layout/fragment_dose_calculator" />

<fragment
    android:id="@+id/menuReferences"
    android:name="com.poultry.poultryscope.ReferencesFragment"
    android:label="@string/references"
    tools:layout="@layout/fragment_references" />
<fragment
    android:id="@+id/menuAboutUs"
    android:name="com.poultry.poultryscope.AboutFragment"
    android:label="@string/about_us"
    tools:layout="@layout/fragment_about" />

The route on the URL cannot be found or you do not have permission to the route (id/menuDrugs).

找不到URL上的路由，或者您没有访问该路由的权限(id/menuDrugs)。

The account being used. Some machines the account is Admin and other not Admin. An Admin would have permission to all files while normal user would not.

正在使用的帐户。某些计算机的帐户是Admin，而其他计算机的帐户不是Admin。管理员将拥有访问所有文件的权限，而普通用户则没有。

I added if condition to handle the click for each item in the menu home and the problem was solved.

我添加了IF条件来处理主菜单中每一项的点击，问题就解决了。

            }

and for drugs click

对于药品，请点击


 if (navController.getCurrentDestination().getId() == R.id.menuhome) {
