Color.parseColor("#rrggbb")
instead of #rrggbb
you should be using hex values 0 to F for rr, gg and bb:
e.g. Color.parseColor("#000000")
or Color.parseColor("#FFFFFF")
From documentation:
public static int parseColor (String colorString):
Parse the color string, and return the corresponding color-int. If the string cannot be parsed, throws an IllegalArgumentException exception. Supported formats are: #RRGGBB #AARRGGBB ‘red’, ‘blue’, ‘green’, ‘black’, ‘white’, ‘gray’, ‘cyan’, ‘magenta’, ‘yellow’, ‘lightgray’, ‘darkgray’, ‘grey’, ‘lightgrey’, ‘darkgrey’, ‘aqua’, ‘fuschia’, ‘lime’, ‘maroon’, ‘navy’, ‘olive’, ‘purple’, ‘silver’, ‘teal’
So I believe that if you are using #rrggbb
you are getting IllegalArgumentException in your logcat
Alternative:
Color mColor = new Color();
mColor.red(redvalue);
mColor.green(greenvalue);
mColor.blue(bluevalue);
li.setBackgroundColor(mColor);
