Android/Java "Convert" String to Button

Question

I have this code:

Button button1 = (Button) findViewById(R.id.button1);
Button button2 = (Button) findViewById(R.id.button2);

String object = "button";
int num;
num = r.nextInt(3 - 1) + 1;
String total = object + num;

I want do set the text for one of the buttons chosen randomly. Something like this:

button<num>.setText(some_text);
      ^ here instead of <num> should be 1 or 2
        and has to be chosen randomly

Answer 1

Like Ondkloss said, you can add your buttons to an array, then randomly select one from that array.

Button[] buttonArray = new Button[2];
buttonArray[0] = button1;
buttonArray[1] = button2;

Random r = new Random();

buttonArray[r.nextInt(2)].setText(someRandomText);

Keep in mind that if you change the number of buttons you will need to change the numbers that I have used (new Button[2] & r.nextInt(2)). My solution works specifically for an array of length 2 containing only 2 buttons. But other than changing the numbers in the array creation and the random number generation to match the number of buttons you have, this solution should work just fine.
