Android resource linking failed (None pre-existing solutions worked)

Question

Android resource linking failed

There's no error shown while coding in the XML file but when I debug, it popups an error message saying,"Android resource linking failed". Commenting the horizontal scroll-views makes the error go away but I need to use it. It's a fragment layout app. Please provide a solution asap!

In your code you have android:background="" you have not given any value for background attribute in your <TextView> whose with android:id="@+id/services" Give some value for background.

   <TextView
        android:id="@+id/services"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_margin="10dp"
        android:background=""     //give value here
        android:gravity="center"
        android:text="Services"
        android:textColor="@color/black"
        android:textSize="18sp"
        android:textStyle="bold" />

Note: Also you can simply your xml code by using <RecyclerView> with adapter and item layout. Make layout file for one item only then use recycler view and adapter. To make recycler view horizontal use these two attributes inside recycler view app:layoutManager="androidx.recyclerview.widget.LinearLayoutManager" android:orientation="horizontal". Then create an List of items with their values to pass to adapter and adapter will automatically set them. To handle click events you can use interface. So your xml will be simplified a lot. With this you can easily add as many items as you want with your code without making changes to xml.

You are referencing the TextView services in the hsv_services HorizontalScrollView as @+id/services.

<TextView
            android:id="@+id/services"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_margin="10dp"
            android:background=""
            android:gravity="center"
            android:text="Services"
            android:textColor="@color/black"
            android:textSize="18sp"
            android:textStyle="bold" />

        <HorizontalScrollView
            android:id="@+id/hsv_services"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_below="@+id/services"
            android:background="@color/silver">

You need to remove the + when referencing other view IDs as the + is used to note that it is a new resource and should be added to the resources file.

<TextView
            android:id="@+id/services"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_margin="10dp"
            android:background=""
            android:gravity="center"
            android:text="Services"
            android:textColor="@color/black"
            android:textSize="18sp"
            android:textStyle="bold" />

        <HorizontalScrollView
            android:id="@+id/hsv_services"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_below="@id/services"
            android:background="@color/silver">
