此方案是看完上面的了博客总结出来的

方案1与方案2兼容~ 因为都是x？ y? font?为名称

方案1：

//values-xhdpi.. Dp的适配 与 values-xhdpi.. Sp的适配

这种适合 默认的那种 要是想非常精确 就考虑额外添加下面那个 的方案

按照以上计算方式，大致可以将市场上的手机划分为5个像素密度等级，具体如下：

(1) ldpi：120dpi，像素密度与dp转换关系为：1dp = 0.75px

(2) mdpi：160dpi ，像素密度与dp转换关系为：1dp = 1px

(3) hdpi：240dpi，像素密度与dp转换关系为：1dp = 1.5px

(4) xhdpi：320dpi，像素密度与dp转换关系为：1dp = 2px

(5) xxhdpi：480dpi，像素密度与dp转换关系为：1dp = 3px

核心思想

基准： 不当成像素 当成多少份 已320*480 生成的文件夹values-ldpi为例

dw:320 dh:480

x1(代表 基准中的一份既 1/320) :

            case ldpi:
                resultDp=dx/0.75F;
                break;
            case mdpi:
                resultDp=dx;
                break;
            case hdpi:
                resultDp=dx/1.5F;
                break;
            case xhdpi:
                resultDp=dx/2F;
                break;
            case xxhdpi:
                resultDp= dx/3F;    

格式如下:

<dimen name="font21px">21.0sp</dimen>//font
<dimen name="x2">2.0dp</dimen>//lay_x
<dimen name="y2">2.0dp</dimen>//lay_y

方案2：

以此为例：//values-1024x600… 的适配

缺点

因为这个是严格按照1024*600的 所以碰到差不多的机型但是不完全匹配的时候 还的依靠xdpi xxdpi mdpi那四个文件夹内的属性

核心思想

基准： 不当成像素 当成多少份 已320*480 生成的文件夹values-1920x1080为例

x1(代表 基准中的一份既 1/320) :1080/320*1(以1080 分成320份在取一份)=3.375px;

y1同上1920/480=4px；
