本文介绍了Android开发中dp（Density-independent Pixels）和sp（Scale-independent Pixels）这两种尺寸单位的概念及应用场景。dp是一种与屏幕密度无关的抽象单位，适用于大多数UI元素的尺寸定义；而sp在此基础上还考虑了用户的字体大小偏好，特别适合于字体大小的指定。

dp Density-independent Pixels – an abstract unit that is based on the physical density of the screen. These units are relative to a 160 dpi screen, so one dp is one pixel on a 160 dpi screen. The ratio of dp-to-pixel will change with the screen density, but not necessarily in direct proportion. Note: The compiler accepts both "dip" and "dp", though "dp" is more consistent with "sp".

sp Scale-independent Pixels – this is like the dp unit, but it is also scaled by the user’s font size preference. It is recommend you use this unit when specifying font sizes, so they will be adjusted for both the screen density and user’s preference.

和字体相关最好用sp
