Color picker for mobile devices with Flex 4.5

2012/01/02 8 comments

I don’t have much experience with Flex. I’ve just participated in the Babelium Project, a web application for language practising developed in Flex, and now I’ve been asked to port an Adobe AIR desktop application to android devices. In this last work, I came across some problems replacing the unsupported MX components by Spark components and some of them where a pain in the neck.

The ColorPicker was a tricky one to substitute. I found this SparkColorPicker, but I couldn’t make it work correctly on a tablet PC (I told you, I’m far from being an expert). The problem seems to be in the ComboBox which extends, as combo boxes and drop down lists are discouraged in AIR for mobile development. When clicking the button, the DropDown was opened and immediately closed making it impossible to choose a color.

After several attempts to fix the issue, I decided to implement my own color picker using the Callout class. This is how it looks like:
