How to randomly receive a Material Design Color?

Question

Google has their Color - Guidelines, so how to randomly receive a color? Is there a way to specify a number from the table and receive a random color out of all colors of the ta

Answer 1

If you want something working with older SDK you can try this way :

TypedArray colors = getResources().obtainTypedArray(R.array.loading_colors);
int index = (int) (Math.random() * colors .length());
int color = colors.getColor(index, Color.BLACK);
textView.setTextColor(color);
colors.recycle();

You need to declare your colors in a arrays.xml :
