Display Listview in Difference Colors

You can hide the second label in the two rows model (by setting the Visible property to false). Set the height of the first label to match the whole item. Then you can use it as as a single row model and give it a different color.

Also would like to control how the results display in scientific notation if result < certain value and > than certain value.

You don't need to do anything special. Just open <project folder>\Objects and take the APK file.
You can then send it to your friends and they will be able to install it.

If you want to upload it to the market then you need to first sign it: Signing your application before uploading to Android market

Thank you Erel, I will give it try.
