  <com.takusemba.cropme.CropLayout

    android:layout_height="match_parent"
    app:cropme_background_alpha="80%"
    app:cropme_frame_height_percent="80%"
    app:cropme_frame_width_percent="80%"
    app:cropme_max_scale="2.0"
    app:cropme_overlay_shape="rectangle"
    app:cropme_with_border="true"
    >

Set your image

cropView.setUri(uri);
// or
cropView.setBitmap(bitmap)

Crop it!

cropLayout.addOnCropListener(object : OnCropListener {
  override fun onSuccess(bitmap: Bitmap) {
    // do somethhing with bitmap.
  }

  override fun onFailure(e: Exception) {

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
  }
}
