How to implement a loading bar with J2me
Do you need a simple, effective j2me loading bar for your long-running operations? And would you like to avoid using (horrible) forms and gauges? Here’s a simple component you can freely use, modify or even ignore 
You can see a live preview on the emulator. To use it, you’ll simply instantiate and start it, like this:
LoadingBar bar = new LoadingBar(100, 40, 5, 10, 0xff0000); bar.start(); |
For an explanation of source code you can go to my Forum Nokia Article: J2ME Canvas Loading Bar. If you simply want rude code, here it is: LoadingBar.java, and here is a sample Canvas using it: LoadingBarCanvas.java.

Hi Cibenxs,
you’re right, its use was not clear from my article, so I’ve posted a sample Canvas that makes use of it. You can find its source code at the end of the post itself.

When and Where should i call the bar.stop method?
I’m not getting it please help me to solve it.

Hi nagesh!
you can call the stop() method in any moment, and it will stop the Timer (and so, the animation) associated to the Loading bar. You should also remember to call it when you do not need the Loading bar anymore, since it will free up resources associated with the animation task itself.
Feel free to ask if you have any more doubts!
