Android Development How to make your app UI nice and generous (color Book II)

We have a headache in the absence of app development: a button to change the color of the past, or it is very difficult to see, eventually only temporarily abandoned, wasting a lot of development time and energy.
Development specification Chapter see Android Development How to make their app UI beautiful, generous (specification article one)

First, the app commonly used with reference

Bottom background color, content background color, two colors similar, but can distinguish
Title Background color any suit
Title text color is usually black or white blackbody
Content text is usually black or white Arial
Unimportant content light Grey
Important content title The color around the background color is usually brighter than the title color, as the accent color
Color combination of color, complementary color, similar color, 3 characters (red, yellow, blue three colors on the Hue ring to form a positive triangle, known as the combination of three primary colors, this combination has a strong dynamic)
The color of an activity interface is best controlled within 3 types

Second, the Fool-style color scheme (pick up using the color picker tool that comes with Android studio) Three, the common color code
