title: How to create imageview with zoom and pan functionality?
body: <p>I created an app that has a small image loaded from URL of a website. I want that when user clicks on that small image it'll show the image in full screen and will also have the ability to zoom and pan that image.</p>
  
  <p>What I've done was showing the image in WebView with built-in zoom controls but the result was ugly. (I've set the layout to wrap_content so no white areas are shown, but it cause the image doesn't zoom dynamically).</p>
  
  <p>Any solution? and sorry for my bad English.</p>
