How to change shade of color dynamically android? -


i'm using palette class programmatically dominant color image want use status bar , toolbar. according material design guidelines, status bar color should 2 shades darker toolbar color.

  bitmap bitmap = ((bitmapdrawable) ((imageview)mimageview).getdrawable()).getbitmap();     if (bitmap != null) {         palette = palette.generate(bitmap);         vibrantswatch = palette.getvibrantswatch();         darkvibrantswatch = palette.getdarkvibrantswatch();     }

for darker color i'm using darkvibrantswatch , lighter color, i'm using vibrantswatch. in of cases, these turn out different each other , hence becoming unusable. there workaround this? maybe if possible 1 color, darkvibrantswatch, , programmatically generate color 2 shades lighter?

i'm not sure getting 2 shades lighter can play around shade_factor , see if can achieve want.

  private int getdarkershade(int color) {         return color.rgb((int)(shade_factor * color.red(color)),                 (int)(shade_factor * color.green(color)),                 (int)(shade_factor * color.blue(color)));     }
