i new android , need help.

is possible?

public class gameactivity extends activity {      @override     protected void oncreate(bundle savedinstancestate){     super.oncreate(savedinstancestate);      view gameview = new gameview(this);     setcontentview(gameview);      }  } 

and gameview class

public class gameview extends view {      private static final string tag = null;     // log.e      private ball ball1;                         // ball1     private gamecontainer gamecontainer;        // frame game     private racket racket;                      // controller     int viewwidth = 0;                          // width onchange     int viewheight = 0;                         // height onchange         private score score;       // constructor     public gameview(context context) {         super(context);          ball1 = new ball(color.green, 24, 10, 2);   // colour, radius,speedx, speedy          ball1.setballlocation(10, 5);   // x, y of ball             gamecontainer = new gamecontainer(color.gray);         racket = new racket(color.black);             score = new score(color.white);          }      @override     public void ondraw(canvas canvas){         gamecontainer.container(1, 2, 100, 100);         gamecontainer.display(canvas);          ball1.drawball(canvas);         ball1.moveball(gamecontainer);          // check ball if out display alert box         if (ball1.getendgame()){             log.e(tag, "end of game");         }        }    } 

plain old java conventions should work.

add getter/setter methods variables need access , use them values.

public int getheight(){      return viewheight; } 

would not work
