title: React Native Android Slider cannot slide vertically on device
body: <p>I've used the <code>Slider</code> component on <code>React Native</code> <code>0.43</code> using the following code. It works fine for iOS as it has a nice big "button" for user to hold and drag. But on android it is just a small dot and I find that I could not drag it vertically (1/10 tries are successful). I find that the "drag" get captured by the <code>ScrollView</code> in the background instead. Help?</p>
  
  <pre><code>      &lt;Slider
          minimumValue={minValue}
          maximumValue={maxValue}
          step={step}
          style={styles.slider}
          value={parseInt(input.value)}
          onSlidingComplete={onSlidingComplete}
          onValueChange={onValueChange}
        /&gt;
  
    slider: {
      marginRight:-100,
      marginLeft:-100,
      width:250,
      transform: [
        { rotateZ : '-90deg' },
      ],
    },
  </code></pre>
