This class will extend FragmentActivity (an android class to create an activity that wants to use support for fragment and API loaders. )įirst, create a superclass that will have abstract methods in it. Here's the magic (once again I'm noting that a lot of this is from the BNR book with just a few extras of my own. Once with graphic fragments and once with widget/XML based fragments. I've implemented this in a couple of ways. Since the shell activity really doesn't do anything, the only really interesting bit here is the Fragment you're going to start, and that's the only thing that morphs from instance to instance as well.īNR delegate that bit to the abstract class. The class is exactly like the one created for you by default with one exception, it comes with a abstract class that will be implemented by later classes which extend this one. Start (or restart if it exists already) the fragment in the container.Connect the Activity to a layout that has a container for the fragment.They observe quite correctly that you're basically going to do two very simple things with your activities now that you're "hooked on fragments." O iStumbler permite escolher a frequência das redes sem fio no painel de controle. Além de mostrar informações detalhadas sobre a rede WiFi, também detecta dispositivos Bluetooth ou serviços Bonjour. They recommend creating a class they call "SingleFragmentActivity". O iStumbler é provavelmente o melhor aplicativo que você pode usar, caso deseje procurar redes sem fio ao seu redor. The guys at Big Nerd Ranch (BNR) take this one step further.
I think there might be a hint there from the folks at Google regarding their feelings about using Fragments.
The Activity created by the SDK doesn't do anything except start a Fragment that is placed inside the container and brings along its own xml layout for the actual view that your app will work it. The presentation and thoroughness of information is definitely a plus, although the crashing and inability to.

Currently if you create a new project in Eclipse you'll get an Activity connected to what is essentially an empty view (OK, there's a simply layout which is called 'container', but it's empty). iStumbler for Mac is a good tool for helping you find open Wi-Fi networks nearby.
