Registry
Registry provides a mechanism for mapping ListView's items to their itemViews. It can generate static code about the item-to-itemView relationship. You'll never care about the item-view-type and view-type-count anymore. They can be counting by Registry automatically.
How to use
Say, we have a multi-view-type ListView which displays two kind of item: Foo and Bar.
- Define an annotation named FooBarList with
@Registerannotation.
@Register public @interface FooBarList {
}
- Define
ViewBinderfor mapping Foo and Bar to their views.
// For Foo. @FooBarList // Indicates it's for FooBarList. @Layout(R.layout.text_view) // Provides layoutRes for Foo's view. public class FooBinder implements ViewBinder<Foo, TextView> {
// R.layout.text_view is a TextView.
@Override public void bindView(Foo item, TextView view) {
// Do binding.
}
}
// For Bar. @FooBarList @Layout(R.layout.linear_layout) public class BarBinder implements ViewBinder<Bar, LinearLayout> {
// R.layout.linear_layout is a LinearLayout.
@Override public void bindView(Bar item, LinearLayout view) {
// Do binding.
}
}
- Create Registry for FooBarList and define the ListView's Adapter.
public class Adapter extends RegistryAdapter {
protected Adapter() {
// Create the Registry.
super(Registry.create(FooBarList.class));
}
// ...
}
Done.
