Randomly change background color on button click?

This is my code:

 @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_my_activity2);
    Button n = (Button) findViewById(R.id.button);
    Typeface typeface = Typeface.createFromAsset(getAssets(), "BebasNeue Bold.ttf");
    n.setTypeface(typeface);
    final TextView tv = (TextView) findViewById(R.id.textView);
    Typeface face = Typeface.createFromAsset(getAssets(),
            "OSP-DIN.ttf");
    tv.setTypeface(face);


    final String[] values = getResources().getStringArray(R.array.things_array);
    n.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Random RAND=new Random();
            String nextValue = values[RAND.nextInt(values.length)];
            tv.setText(nextValue);
        }
    });
}

I also have this:

<string-array name="colorcode_array">
<item>3498db</item>
<item>2ecc71</item>
<item>9b59b6</item>
<item>f1c40f</item>
<item>1abc9c</item>
<item>2980b9</item>
<item>8e44ad</item>
<item>e41c1c</item>
<item>2ecca9</item>
<item>752ecc</item>
<item>4f2ecc</item>
<item>2eccc3</item>
<item>2ecc53</item>
<item>2ecc2e</item>
<item>5bcc2e</item>
<item>9ecc2e</item>
<item>cca12e</item>
<item>cc712e</item>
<item>f1c209</item>
<item>86f109</item>
<item>f11616</item>
<item>9c1818</item>
</string-array>

Now what I would need is that the moment the button is clicked, you can see that the button already randomley loads text into the textview from things_array, but at the same time I want the background color to change randomly by using the color codes in colorcode_array.

How can I do this?

view.setBackgroundColor(Color.parseColor("#"+array[index])); should do it for you :)

(your case: view = tv and array[index] = nextValue
