cb.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener(){

}
});

I’m still working on http://www.pragprog.com/titles/eband/hello-android, it hasn’t been published yet, but you can purchase a priliminary PDF right now. It seems pretty good so far with lots of good material for those just starting out. I’m looking forward to the OpenGL chapter and ContentProviders for data access on the Android platform.

As far as using checkboxes, you have to either build your screens by hand and include a CheckBox object, or the preferred method is to create a layout XML file in the res directory. This layout file tells Android which widgets you want on a display and their layout. This is discussed in the Hello Android book and in Google’s Development documentation at, http://code.google.com/android/documentation.html . The CheckBox is specifically metioned in it’s API section at, http://code.google.com/android/reference/android/widget/CheckBox.html .

Good luck, hope this helps!
