title: Display a random image when a button is clicked
body: <p>I tried earlier and just got more confused so i will try and be more precise.  I am making an app in which i have a deck of 7 cards.  I want to click on the deck and have one of the 7 cards pop up on the screen.  So far I have </p>
  
  <pre><code> public void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.main);
  
          final MediaPlayer mpClick = MediaPlayer.create(this, R.raw.click);
          randomM = (EditText) findViewById(R.id.randomM);
  
          //button 1 start        
          Button bMythos = (Button) findViewById(R.id.mythos);
          bMythos.setOnClickListener(new View.OnClickListener() {
  
              @Override
              public void onClick(View v) {
                  // TODO Auto-generated method stub
                  mpClick.start();
                  Random r = new Random();
                  int n=r.nextInt(7) + 1;
                  randomM.setText(String.valueOf(n));
              }
          });
          //button 1 end
      }
  
  }
  </code></pre>
  
  <p>So far this displays the card deck which i click on and a random number is generated (the text box is nearly for me to know the random number generator is working; will be removed when i figure out the display).  </p>
  
  <p><strong>So my question</strong>
  How can i get the random number to correspond with a random card and get the card displayed?   - the cards are labeled mythos1, mythos2, etc so i assumed i could do something with mythos(String.valueOf(n)) but that didn't work (unless i'm doing something else wrong)  [if you can't tell i have no idea what i'm doing] </p>
