title: android go back button
body: <p>I want to build a "quotes app" so every time the user clicks on the button a random quote appears. But I also want to set an button, which takes the user back to the quote he saw before. And because it always picks a quote randomly I wanted to store the int number of the quote, so every time someone clicks the button it stores in a int string which quote has been shown. But I get errors all the time. can someone give me an sample code for such a back-button? thanks (button2 should be bak button)</p>
  
  <p>final int[] Random2 = {};</p>
  
  <pre><code>    button1.setOnClickListener(new View.OnClickListener() {
  
          public void onClick(View v) {
              // TODO Auto-generated method stub
               Zufallszahl1 = Würfel.nextInt(98);
  
               Random2[counter] = Zufallszahl1;
              counter++;
  
  
                  text1.setText(Lines[Zufallszahl1]
  
              );
  
          }
  
      });
  
  
      button2.setOnClickListener(new View.OnClickListener() {
  
          public void onClick(View v) {
              // TODO Auto-generated method stub
  
              text1.setText(Lines[Random2[counter-1]]);
          }
      });
  
  
  
  }
  </code></pre>
