        android:dashWidth="20sp"

set android:layerType="software" for your imageView. Check the docs for android:layerType.

Try changing sp to dp to:

<stroke
    android:dashWidth="20dp"
    android:dashGap="20dp"
    android:width="2dp"
    android:color="#FF0000" />

Stroke WIDTH must be smaller than the size HEIGHT.

(Stroke width is the width of the line. Size height is the height of the drawable. When drawn, the line is centered in the drawable. If size height <=stroke width, the line won't show up.)

sp uses the scale factor of the device's font setting, rather than just the scale factor of the screen's density (dp) - don't use sp for non-text related dimensions.
