Android Studio Recycler View Vertical Spacing Too Big

Question

So I am trying to create a Recycler view that will have the images display in a way that you don't have to scroll down; just a 3x3 box of items but I am not sure how to correct the vertical space in my code. The vertical space is length of the display. So I have 3 items display and then I have to scroll down the length of the screen to see another 3 items.

            android:layout_marginStart="106dp"
            android:layout_marginTop="70dp"
            android:layout_marginEnd="106dp"
            android:layout_marginBottom="40dp"
            android:layout_weight="1"
            android:paddingStart="25dp"
            android:paddingEnd="25dp"
            android:visibility="visible"
            tools:listitem="@layout/tutorial_layout" />

    </LinearLayout>
    ​
</ScrollView>

I'm not sure what I am doing wrong because my layout_height is equal to warp_content and not match_parent in the RecyclerView
