                }

                @Override
                public View getView(int position, View convertView, ViewGroup parent) {
                        // TODO Auto-generated method stub
                        ImageView im = new ImageView(mcontext);
                        im.setImageDrawable(getResources().getDrawable(drawables[position]));
                        return im;
                }
               
        }
}

viewfilipper 本身不能加载adapter ,但是可以给他传递getview viewflipper.addview(getview()) 这样可以
