An APK is just in zip format. You can unzip it like any other .zip file.
You can decompile .dex files using the dexdump tool, which is provided in the Android SDK.
See https://stackoverflow.com/a/7750547/116938 for more dex info.
You can decompile an apk on Android device using this : https://play.google.com/store/apps/details?id=com.njlabs.showjava

This website will decompile the code embedded in APK files and extract all the other assets in the file.
Also you can use Android Multitool. You can make minor changes in the app like hiding GUI elements or modifying small part of Logic and rebuild the apk. Its easy to use and decompile/recompile apk and jar files. Here is the Link you can checkout.

You can also use the apktool: http://ibotpeaches.github.io/Apktool/ which will also give you the xml res files. Along with that you can also use the dex2jar system which will output the dex file in the apk to a jar file that can be opened with JD-GUI and exported to standard java files.
I have created a tool that combines dex2jar, jd-core and apktool: https://github.com/dirkvranckaert/AndroidDecompiler Just checkout the project locally and run the script as documented and you'll get all the resources and sources decompiled.
