Trying to extend a class, while onseekbarchangelistener is implemented?
I have 3 classes i am working with, a drawing view which sits inside of the drawing box and a tools button. My tools button has the seekbar and listener for the size change of my stroke, the stroke is in the canvasview class, i am trying to extend my canvas view with the tools class but i have the
public class Toolbox extends AppCompatActivity implements SeekBar.OnSeekBarChangeListener
when i try to add the extends canvasview i get an error. How do i go about doing this?
