title: on touch of image, image view to fullscreen and zoom should work
body: <p>I'm loading Image from server to imageview. I'm using Picasso to load the image from server to imageview.</p>
  
  <p>On touch of that image, i want it to appear fullscreen and even zoom/tap should work.</p>
  
  <p>I don't know what to do for this, Please help me with suggestions or some examples.</p>
  
  <p>I found few examples, but there was more than 1000 lines code, I couldn't find it helpful and I didn't understand what to do with it. </p>
  
  <p>Thanks.
  this is my code.</p>
  
  <pre><code>image = (ImageView) findViewById(R.id.image);
  image.setOnClickListener(this);
  
  Picasso.with(this).load("http://Imageurl").into(image);
  
  @Override
  public void onClick(View view) {
      switch (view.getId()) {
          case R.id.image:
  
              //what to do here ?
  
               break;  
     } 
  }
  </code></pre>
