如何在 android 中以编程方式更改自定义 UI 元素的特定 XML 属性

Question

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?

Answer 1

In NeomorphFrameLayout you can add a public function changeElevation ex

 fun changeElevation(elevation :Float){
      neomorph_elevation = elevation
    }

and can use in onClickListener like

btnsystem.changeElevation(5f)

Answer 2

As they specified in library that,

Attributes: neomorph_clickable option set it to true and onClick trigger a function from xml or from setOnClickListener whichever you prefer...
