[android-developers] How to Draw a Button in a View

hi guys,

i have a class which extends a View and i'm drawing few images in the
canvas.
and i want to draw two buttons as well. could someone tell me how to
do this???

this is my class

public class DrawView extends View {
private ColorBall colorball1;

String[] str;
int width, height;

Context ctx;

public DrawView(Context context, int width, int height, InputStream
is,
String[] str) {
super(context);
setFocusable(true); // not yet necessary, but you never know what
the
// future brings
// declare each ball with the ColorBall class
// if(color.equals("blue")){
this.ctx = context;
this.str = str;
this.height = height;
this.width = width;

colorball1 = new ColorBall(context, is, height, width);

}

@Override
protected void onDraw(Canvas canvas) {

colorball1.moveBall(5, 3);

// draw the balls on the canvas
canvas.drawBitmap(colorball1.getBitmap(), colorball1.getX(),
colorball1
.getY(), null);

Button btnAnswer = (Button) findViewById(R.id.button1);
Button btnEnd = (Button) findViewById(R.id.button2);

// refresh the canvas
invalidate();
}
}

even i have created two button but how can i make them visible??

Mike
