title: glide take time to load image even if image load from cache?
body: <p>I have <code>RecyclerView</code> where image load from server URL. so I use Glide library to load an image, glide store image into cache to reload as fast as possible.
  I use a <code>placeholder()</code> as a loader for loading image first time, but if I off the internet and start app its still load placeholder first and then load an image into <code>ImageView</code>.
  So, my question is, is there any way to load an image into <code>ImageView</code> so user experience like smoothness (offline) app while loading images        </p>
  
  <pre><code>Glide.with(context)
          .load(www.abc.com/abcd.jpg)
          .placeholder(R.drawable.placeholder)          
          .into(viewHolder.ivSleepImage)
  </code></pre>
  
  <p>you can check this app <a href="https://play.google.com/store/apps/details?id=org.wakingup.android&amp;hl=en" rel="nofollow noreferrer">Walking UP</a> it loads image first time than there is no loader, and next time when image load means when you open app image already loaded in list. </p>
  
  <p>Please somebody help me to achieve this task</p>
