Fragment support

Fragment, ListFragment support.

Fragment is naturally supported from the current version 0.8.5. The demo for Fragment is added to Gallery project.

The gallery app shows using the more advanced FragmentManager method, but is using simple tags supported?

For instance I have a landscape layout xml that has:

<LinearLayout ...>
    <fragment
        ...
        class="com.example.MainActivity$LeftFragment/>

    <fragment
        ...
        class="com.example.MainActivity$RightFragment/>
</LinearLayout>

And in the Fragment's onCreateView function I have:

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {

    PresModel pm = new PresModel();
    BinderFactory factory = new BinderFactoryBuilder()
            .add(new DynamicViewBinding()
                    .forView(Switch.class)
                    .oneWayProperties("checked")
                    .oneWayProperties("enabled"))
            .build();
    View rootView = factory.createViewBinder(inflater.getContext())
            .inflateAndBindWithoutAttachingToRoot(R.layout.fragment_left, PresModel,container);
    return rootView;
}

The .inflateAndBindWithoutAttachingToRoot function throws java.lang.NullPointerException: Root must not be null. This function works fine in my portrait mode layout (it uses a ViewPager).

@bj0,

The container of ViewGroup is null. You will need to use viewBinder.inflateAndBind instead. You can find the example here - https://github.com/RoboBinding/Android-CleanArchitecture/blob/master/presentation/src/main/java/com/fernandocejas/android10/sample/presentation/view/fragment/UserListFragment.java

Simple fragment tag is not supported at the moment. We will add the support in future. There is a related issue here - #194 .

Actually I did get it to work with .inflateAndBind. I put the following in onCreateView

if( container == null )
    rootView = factory.createViewBinder(inflater.getContext())
            .inflateAndBind(R.layout.fragment_left, PresModel);
else
    rootView = factory.createViewBinder(inflater.getContext())
            .inflateAndBindWithoutAttachingToRoot(R.layout.fragment_left, PresModel,container);

And it appears to be working fine now.
