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

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
