Randomize strings without repetition

Question

I'm making a game that needs to appear random phrases on the screen, but they are constantly repeating.

How can I make them appear randomly with no repetitions?

Here is the code:

{
                                    wordList[0] = "Sou Mexicano";
                                    wordList[1] = "Ajuda-me";
                                    wordList[2] = "Salva-me";
                                    wordList[3] = "Vamos Ganhar";
                                    wordList[4] = "Estou sem palavras";
                                    wordList[5] = "Amo Esparguete";
                                    wordList[6] = "Criei o Mundo";
                                    wordList[7] = "Sou Cientista";

                                  String wordToDisplay = wordList[randomInt];
                                  TextView frase = (TextView) findViewById(R.id.textView7);
                                  frase.setText(wordToDisplay);

Sorry if this is a duplicate question but I already searched and didn't find the solution for this one.

Answer 1

I was able to find a method that makes the words repeat fewer times. Here's the code:

Random randomGenerator = new Random();
int randomInt = randomGenerator.nextInt(100);
String wordToDisplay = wordList[randomInt];
TextView frase = (TextView) findViewById(R.id.textView7);
frase.setText(wordToDisplay);
List<String> valores = new ArrayList<String>();
valores.add(wordToDisplay);
Collections.shuffle(valores);

Answer 2

Make a copy of your list. Shuffle the copy. Pick the phrases off the list in the shuffled order until they are all used. If necessary make another copy and shuffle it. You will get the same phrases, but in a different order. Java has Collections.shuffle(), I am not sure about Android.
