I have to display default image first,then the loaded image is placed on default image asynchronously.I开发者_JS百科 do not have an idea how can i do this. Please help me.

First, use some default image from project resources, same for all rows.

Then for each row run a thread to load image, use a callback in thread to update list field row when image is loaded. See Coderholic: Blackberry WebBitmapField

Remember that we can use only limited number of threads in Blackberry application. So better create some thread pool with 3-5 threads running.
