Thanks Jeff! It worked but by overriding the onDraw call not the
dispatchDraw.
@Override
onDraw(Canvas canvas) {
canvas.save();
canvas.rotate(45);
super.onDraw(canvas);
canvas.restore();
}
I tried the same method on an ImageView extended class but I didn't
get the same rotation, nothing happend than... any ideas?
canvas contains all that the user can see right? So if it was a
LinearLayout the canvas will be what ever is contained inside it?
Sorry I 'm very new to graphics :P
Thanks!
