写了一版和版本有关系的代码

Display display = getWindowManager().getDefaultDisplay();
            int width,height;
            if(Build.VERSION.SDK_INT>=13){
                Point size = new Point();
                display.getSize(size);
                width = size.x;
                height = size.y;
            }else{
                height = display.getHeight();
                width=display.getWidth();
            }
