Is there a common way to show a big image and enable the user to zoom in and out and pan the image?
Until now I found two ways:
I used a WebView and loaded the image from the memory via
webview.loadUrl("file://...")
The WebView handles all the panning zooming and scrolling. If you use wrap_content the webview won't be bigger then the image and no white areas are shown. The WebView is the better ImageView ;)
