Display Thumbnails and create a Photo Picker

Using two previously published libraries it is simple to create a library that will resize and display a selection of images in a table. With some additional work, a Photo Picker dialog is possible.

The two libraries used are the ImageManipulator, and the TableLayoutManager. The library attached to this article can be used to create a table of thumbnails or a Photo Picker from either an array of images or a directory in the file system.





Photo Picker



The implementation defines a Listener interface for receiving the BlackBerry smartphone user’s selection. The listener implementation receives the resized thumbnail image as well as its index in the table and the file name if a directory was specified.

Thank you for publishing this code. It works great, and I was able to successfully test it on the simulator. Once I put it on the real device, it took about 20 seconds to load EACH image with GC occurring nonstop. This causes it to be unusuable. How can we make this more efficient so it can actually be put to use?

Has anyone been able to use this code on a real phone? I've tried populating the table with images from BBThumb.dat but it is still way way too slow on a real phone and is unusable.

It's slow there too... I'm trying to load images from camera, but it's too slow.
