title: Android onTouchListener with ImageView and PDFRenderer
body: <p>Can some body help me with some understanding about <code>onTouchListners</code>??
  I am new to android...and doing something more complex I guess..</p>
  
  <p><strong>1. I have a main Activity class which renders a list of 7 pdf files</strong></p>
  
  <p><strong>2. there exists a PDF class which renders the selected item as a new pdf file(done using pdf renderer)</strong></p>
  
  <p><strong>3. there exists a flip class to take care of flipping pages on touch</strong></p>
  
  <p>I am confused about, where to place the following method as it is never getting called if placed correctly and it shud help me deliver the next or previous pdf page..</p>
  
  <pre><code>public boolean onTouch(View v, MotionEvent event) {
           return gDetector.onTouchEvent(event);
     }
  </code></pre>
  
  <p>Thank u..</p>
