title: Bitmap with a color layer
body: <p>I have a ImageView where I put a Bitmap (left), sometimes I wanna see bitmap with a semitransparent blue layer (right). I try with a ColorFilter (LightingColorFilter and PorterDuffColorFilter) but I get a dark blue, how can I do this with ColorFilter or anything else?</p>

  <p>Thanks.</p>
  
  <p>EDIT (I tried this and other variants)</p>
  
  <pre><code> //ColorFilter filter = new PorterDuffColorFilter(color.wather, PorterDuff.Mode.DST_OVER);
   ColorFilter filter = new LightingColorFilter(color.mul, color.wather);
   // mul = 0xFFFFFFFF and wather = 0x7000FFFF
  
   BitmapScaler scaler = new BitmapScaler();
   imagen.setImageBitmap(scaler.getScaled());
   imagen.setColorFilter(filter);
  </code></pre>
  
  <p>I tried diferents mul, add values and always get this:
