title: setColorFilter not working
body: <p>I'm trying to implement a simple colorfilter on an imageview to turn the black image into a white image. In order to achieve that I do the following:</p>
  
  <pre><code>    weatherImg.setColorFilter(Color.BLACK, PorterDuff.Mode.MULTIPLY);
      weatherImg.setImageResource(R.drawable.b_clouded_rain);
  </code></pre>
  
  <p>I've also tried to change to color in the color filter to red and white but all of them have no effect, what am I doing wrong?</p>
