使用SeekBars管理按钮的RGB参数

Question

I'm a novice programmer and I'm working on one of the my first projects on Android Studio for a school work.

I have to create an application that manages RGB parameters of a button in order to change its color.

Layout consist of 3 seekbars, the first of them manages Red parameters, the second one Green parameters and the third one Blue parameters. Obviously there is a button, too.

In which way can I "connect" these seekbars to the button in order to change its RGB values? Are there specific functions to manage RGB parameters of a button by using some SeekBars for everyone of these parameters?

Answer 1

Have each seekbar give you a String hex value between 0 and FF, then assemble those values and parse the color:

myColor = "#" + redSeekBarValue + greenSeekBarValue + blueSeekBarValue
yourButtonHere.setBackgroundColor(Color.parseColor(myColor));
