Creating an empty Drawable in Android

Question

Creating a Drawable that is completely empty seems like a common need, as a place holder, initial state, etc., but there doesn\'t seem to be a good way to do this... at least in

Answer 1

For me it didn't work when I tried to use @android:id/empty when making an empty drawable. For me, @android:color/transparent was the one.

Answer 2

To create an empty Drawable image, you may use ShapeDrawable with transparent color:

val shapeDrawable = ShapeDrawable(OvalShape())
shapeDrawable.paint.color = context.getColor(android.R.color.transparent)

If the image size is important, use:

shapeDrawable.intrinsicWidth = 100
shapeDrawable.intrinsicHeight = 100
