You can see more detail in app module.
class CustomCropOverlay @JvmOverloads constructor(
context: Context,
attrs: AttributeSet? = null,
defStyleAttr: Int = 0,
cropOverlayAttrs: AttributeSet? = attrs
) : CropOverlay(context, attrs, defStyleAttr, cropOverlayAttrs) {
override fun drawBackground(canvas: Canvas, paint: Paint) {
// draw background
}
override fun drawCrop(canvas: Canvas, paint: Paint) {
// draw croppling frame
}
override fun drawBorder(canvas: Canvas, paint: Paint) {
// draw borders
}
