Cannot solve symbol "RAND"

Question

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) {
            String nextValue = values[RAND.nextInt(values.length)];
            tv.setText(nextValue);
        }
    });
}

At the values[RAND, RAND is red and says it cannot be solved?

How can I fix this?

Answer 1

You have to do this :

Random r = new Random();
r.nextInt(values.length);

See that : http://www.tutorialspoint.com/java/util/random_nextint_inc_exc.htm

EDIT :

ArrayList<Integer> alReadyGet = new ArrayList<Integer>();
Random r = new Random();
n.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
        int nextValue = r.nextInt(values.length);
        for (int i =0; i < alReadyGet.size(); i++) {
            if (alReadyGet.get(i) == nextValue) {
                nextValue = r.nextInt(values.length);
            }
        }
        alReadyGet.add(nextValue);
        tv.setText(values[nextValue]);
});

I think it will work :) Tell me :p

Answer 2

You missed to define RAND

Random RAND=new Random();
