title: Zoomable View in Android?
body: <p>I want to build an Image based application like "Maps for Android". My application have an Activity display a big image[ImageView]. I want put "Pins"[Like custom overlay in Map] on this "big image". I want zoom in, zoom out, double tap zoom in, zoom out an scroll this Activity.</p>
  
  <p>I found an example, an image zoom-able view:

  <p>But it doesn't zoom view, it's just redraw a part of image.</p>
  
  <p>Anybody have an idea?</p>
