I'm trying to make a program generate a text randomly and let that text be color randomly too but I don't know how. Can be in either Java or Kotlin.

There are two approaches

  1. Using predefined colors as in

    In colors.xml

    <item name="blue" type="color">#FF33B5E5</item>
    <item name="purple" type="color">#FFAA66CC</item>
    <item name="green" type="color">#FF99CC00</item>
    <item name="orange" type="color">#FFFFBB33</item>
    <item name="red" type="color">#FFFF4444</item>
    <item name="darkblue" type="color">#FF0099CC</item>
    <item name="darkpurple" type="color">#FF9933CC</item>
    <item name="darkgreen" type="color">#FF669900</item>
    <item name="darkorange" type="color">#FFFF8800</item>
    <item name="darkred" type="color">#FFCC0000</item>
    
    <integer-array name="androidcolors">
        <item>@color/blue</item>
        <item>@color/purple</item>
        <item>@color/green</item>
        <item>@color/orange</item>
        <item>@color/red</item>
        <item>@color/darkblue</item>
        <item>@color/darkpurple</item>
        <item>@color/darkgreen</item>
        <item>@color/darkorange</item>
        <item>@color/darkred</item>
    </integer-array>
    

    In onCreate()

    int[] androidColors = getResources().getIntArray(R.array.androidcolors);
    int randomAndroidColor = androidColors[new Random().nextInt(androidColors.length)];
    view.setBackgroundColor(randomAndroidColor);
    
  2. Using Random RGB coloring as in

    Random rnd = new Random();
    currentStrokeColor = Color.argb(255, rnd.nextInt(256), rnd.nextInt(256),rnd.nextInt(256));
