Idea: Suppose my current machine screen width and height of 1920 * 1116, a component of my page width is 100px, then in 1280 * 800 machines, stands to reason that should be the 100/1920 * 1280 = 66.66px, then the reason the idea came, if I fit in 1920 * 1116, according to 1280/1920 so wide, high conversion in accordance with 800/1116 can not it do?
Difficulty: write configuration file
1. documented in the application resource file, such as my current machine is 1920 * 1116, 1280 * 800 I would like to also use, is two folders: values-1920x1116, values-1280x800
private final static String VALUE_TEMPLATE = "values-{0}x{1}";
System.out.print("TEST::"+w+"?"+h);
File fileDir = new File(dirStr + File.separator
+ VALUE_TEMPLATE.replace("{0}", w + "")//
.replace("{1}", h + ""));
fileDir.mkdir();
2, if my current machine is 1920 * 1116, then my values-1920x1116 years should have horizontal and vertical adaptation adaptation file documents,
