I am making a tile based game in Android Studio. I want the map to output circles (islands) if it loops past a 1, and the circle should be in the correct grid coordinates howeve
Along with color, you also need to set a few other things:
paint.setStyle(Paint.Style.STROKE);
or
paint.setStyle(Paint.Style.FILL);
It's possible that your onDraw method isn't being called. If adding the paint style doesn't fix your problem entirely, you should probably verify that onDraw is being called with a log at the beginning of the method.
