I am using a custom UI component in my project which has it's own few attributes. I want to change a specific one using a function when it is clicked. I don't know how to access it though, I am fairly new in this department.

<com.chinodev.androidneomorphframelayout.NeomorphFrameLayout
                    android:id="@+id/btnsystem"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:layout_margin="5dp"
                    app:neomorph_background_color="@color/appBackground"
                    app:neomorph_corner_radius="10dp"
                    app:neomorph_elevation="4dp"
                    app:neomorph_highlight_color="#ffffff"
                    app:neomorph_shadow_color="#CDCDCD"
                    app:neomorph_view_type="rectangular">

here say I want to change the app:neomorph_elevation using onclick function how can I do that?
