int totalWidth = display.getWidth();
int totalHeight = display.getHeight();

ImageView curView = (ImageView)layout.findViewById(R.id.imageView1);
LayoutParams para = curView.getLayoutParams();
para.height = (int)(totalWidth * 0.8);
para.width = (int)(totalWidth * 0.8);
curView.setLayoutParams(para);
