I adding newt for the UX changes ok?

Nested ScrollViews are bug-prone and cause weird behavior in Android. It's also
a strange user experience. How does it look if you leave this as a FrameLayout?

I changed ColorPickerSimple to a GridView so we no longer have nested scroll
views.

             android:id="@+id/color_picker_simple_border"
             android:layout_width="match_parent"
-            android:layout_height="wrap_content"
+            android:layout_height="100dp"
             android:background="@drawable/color_picker_border"
             android:paddingStart="1px"
             android:paddingEnd="1px"
             android:paddingTop="1px">
 
             <org.chromium.ui.ColorPickerSimple
                 android:id="@+id/color_picker_simple"
+                android:minHeight="99dp"
                 android:layout_width="match_parent"
-                android:layout_height="100dp"/>
-        </FrameLayout>
+                android:layout_height="match_parent"/>
+        </ScrollView>
 
         <FrameLayout
             android:id="@+id/more_colors_button_border"
             android:layout_width="match_parent"
             android:layout_height="wrap_content"
             android:layout_below="@+id/color_picker_simple_border"
             android:background="@drawable/color_picker_border"
             android:padding="1px">
 
             <org.chromium.ui.ColorPickerMoreButton
                 android:id="@+id/more_colors_button"
                 style="?android:attr/buttonBarButtonStyle"
                 android:layout_width="match_parent"
                 android:layout_height="wrap_content"
                 android:minHeight="48dp"
                 android:textAppearance="?android:attr/textAppearanceSmall"
                 android:text="@string/color_picker_button_more" />
         </FrameLayout>
 
     </RelativeLayout>
