title: Calling random value from an array list
body: <p>I am very new to android programming on eclipse and I have a problem trying to figure out on how to call random values from a list in an array. My codes as follows:</p>
  
  <pre><code>final float column_positions[][] = new float[][] {
      { 600, 0.5f },
      { 900, 0.3f },
      { 1200, 0.2f }
  };
  </code></pre>
