Based on experiments, adapters in client project are preferred over adapters from library. What if I want to customize these adapters?Īlthough BindingAdapters can be overridden, it hasn't been specified how databinding resolves the conflicts. You can use BindingUtils.java as a reference to roll out your own attributes. This project aims to provide a pattern so you can build your own custom XML attributes that fulfill your usecase. It may not be feasible to create a generic API that works well for all usecases. What if I need to use some other View?Įvery application has different requirements. Public static void bindLayoutManager( RecyclerView recyclerView, boolean vertical) Ĭheck the source ( BindingUtils.java) to know how these work. Public static void bindAdapterWithDefaultBinder( ViewPager viewPager, Observable> items, ViewProvider BindingConversion public static ViewProvider getViewProviderForStaticLayout( LayoutRes final int BindingConversion public static Observable> toListObservable List BindingAdapter( "layout_vertical") setDefaultBinder( new ViewModelBinder() Override public void bind( ViewDataBinding viewDataBinding, ViewModel viewModel) ) Using a single variable vm provides a consistent mechanism to configure any View:īindingUtils. This helps in reusing functionality for a different layout. Multiple views can share a single view model. Idea is that the ViewModel should have all information required to display the View. This pattern makes use of Data Binding, such that views contain exactly 1 variable vm i.e. As the main deliverable of this library is the pattern, it is important to understand the principles behind it, so that the pattern can be applied even at places where the library APIs aren't available. Getting Started provides a tutorial to setup the library and gives an idea about its functionality.
