我在 Play 商店中有一个可以在所有手机上运行的应用程序，现在我也想在平板电脑上发布它。

1) 图像是为 xhdpi 屏幕设计的。所以我认为这也足以支持平板电脑，还是应该为平板电脑单独重新设计图像？

2）我想将 dimens.xml 分成 3 个类别 -

• dimens.xml 适用于所有手机
• dimens.xml 适用于所有 7 英寸平板电脑
• dimens.xml 适用于所有 10 英寸平板电脑

我想出的解决方案是像下面这样划分 values 文件夹 -

• 值/尺寸.xml
• 值-sw620dp/dimens.xml
• 值-sw720dp/dimens.xml

但是由于很少有手机可能属于values-sw620dp/dimens.xml或values-sw720dp/dimens.xml，那么将dimens.xml分为3类的合适方法是什么？

请不要发布下面的图片，因为我想分为 3 类 以下是许多人回答的结构
