我在我的项目中使用DataBindings和RecyclerView.我有RecyclerView的基础适配器.看起来像这样

public abstract class BaseAdapter<T extends ViewDataBinding> extends RecyclerView.Adapter<BaseAdapter.ViewHolder> {

    public BaseAdapter() {}

    public class ViewHolder extends RecyclerView.ViewHolder {

        public T binding;

        public ViewHolder(View view) {
            super(view);
            binding = DataBindingUtil.bind(view);
        }
    }

    @Override
    public void onBindViewHolder(ViewHolder holder, int position) {
        ... code ...
        }

}

ViewHolder扩展类只有绑定字段类型不同.在扩展BaseAdapter类的实现之后:

public class BaseAdapterExtended extends BaseAdapter<BaseAdapterExtendedBinding> {

    public BaseAdapterExtended(ArrayList<ItemModel> itemModels) {
        super();
        mData = itemModels;
    }

    @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        LayoutInflater inflater = LayoutInflater.from(parent.getContext());
        return new ViewHolder(BaseAdapterExtendedBinding.inflate(inflater, parent, false).getRoot());
    }

    @Override …

我想在GWT中创建一个复合,它需要一个扩展类并实现接口的类.Psudo代码如下(它显然不起作用):

class GridRow<T extends Widget implements HasText> extends Composite{
  //more codes here
}
