A glimpse at generating colors.xml
Here’s an explanation of some of the most crucial aspects related to creation of colors.xml:
* Colors– While building a colors.xml, a color value is being specified with an RGB value and an alpha channel. Moreover, you can even opt for using the color resource at a location that easily accepts a hexadecimal color value. There’s also an option for using a color resource when the drawable resource is expected to be available in XML. Each of the color value begins with a pound(#) characters, followed by Alpha-Red-Green-Blue information. For example, #RGB, #RRGGBB, #ARGB and #AARRGGBB.
* Dimension– Defined in XML, dimension is being specified using a number that’s followed by a unit of measure. For example, 10px, 5sp, 2in etc. Here’s a list of units of measure that are being supported by Android.
* sp– An abbreviation for Scale-independent Pixels, sp is just like the dp unit with only one exception that it can be easily scaled in accordance to the user’s font size preference. I would recommend you to use the sp unit while specifying the font sizes, enabling the adjustment for both screen density/resolution as well as the client’s unique preference.
* px– An abbreviation for Pixels, px represents the actual pixels on the screen. The reason why designers prefer avoiding px unit is that its representation can easily vary across devices, with only a fewer number of pixels available on the screen.
