```xml
<com.dd.ShadowLayout
    ohos:height="match_content"
    ohos:width="match_content"
    ohos:top_margin="16vp"
    app:sl_shadowRadius="4vp"
    app:sl_shadowColor="$color:shadow"
    app:sl_dx="0vp"
    app:sl_dy="0vp"
    app:sl_cornerRadius="56vp">

    <Button
        ohos:height="56vp"
        ohos:width="56vp"
        ohos:foreground_element="$media:ic_add_white"
        ohos:background_element="$graphic:fab_selector"
        tools:ignore="ContentDescription"
        />
</com.dd.ShadowLayout>
```

Explanation

- `app:sl_cornerRadius="56vp"` - set corner radius to the same value as child view size to make it circle.
- `app:sl_dx="0vp"` `app:sl_dy="vdp"` - center shadow.
- `app:sl_shadowColor="#AA000000"`- shadow color.
- `app:sl_shadowRadius="4vp"`- shadow radius (shadow distance and bluer - works as `elevation`)

**Floating Action Button** with offset shadow.
