java - How I change the colors of my buttons between one array colors? -


i'm trying change colors of buttons 1 array colors pre-defined. this:

  string[] colors = {"#2962ff", "#00bfa5", "#ff6d00", "#aa00ff"};         random random = new random();         string myrandstring = random.nextint(colors.length);          // buttons         ingridlayout00.setbackgroundcolor(myrandstring);         ingridlayout01.setbackgroundcolor(myrandstring);         ingridlayout10.setbackgroundcolor(myrandstring);         ingridlayout11.setbackgroundcolor(myrandstring);

but don't know how fix this.

you doing great need pass random number array , color random index number

  int[] colors = {#2962ff, #00bfa5, #ff6d00, #aa00ff};          random random = new random();          int myrandstring = random.nextint(colors.length);            // buttons          ingridlayout00.setbackgroundcolor(color.parsecolor(colors[myrandstring]));          ingridlayout01.setbackgroundcolor(color.parsecolor(colors[myrandstring]));          ingridlayout10.setbackgroundcolor(color.parsecolor(colors[myrandstring]));          ingridlayout11.setbackgroundcolor(color.parsecolor(colors[myrandstring]));

all have 

setbackgroundcolor(colors[myrandstring]);

which gets color random index number
