[移动开发]Android基于ViewBinding实现通用Adapter基类

首先是BaseAdapter，泛型里面传入数据类型和ViewBinding

public abstract class BaseAdapter<T,V extends ViewBinding> extends RecyclerView.Adapter<BaseHolder> {
    private List<T> data;

    public BaseAdapter(List<T> data) {
        this.data = data;
    }
    @NonNull
    @Override
    public BaseHolder<V> onCreateViewHolder(@NonNull ViewGroup viewGroup, int i) {
        return new BaseHolder(onBindingView(viewGroup));
    }

    @Override
    public void onBindViewHolder(@NonNull BaseHolder holder, int position) {
        onBindingData(holder,data.get(position),position);
    }

    protected abstract void onBindingData(BaseHolder<V> holder, T t, int position);
    protected abstract V onBindingView(ViewGroup viewGroup);

    @Override
    public int getItemCount() {
        return data==null?0:data.size();
    }
}

BaseHolder

public class BaseHolder<V extends ViewBinding> extends RecyclerView.ViewHolder {
    private V viewBinding;

    public BaseHolder(V viewBinding) {
        super(viewBinding.getRoot());
        this.viewBinding = viewBinding;
    }

    public V getViewBinding() {
        return viewBinding;
    }
}

?之后在使用Adapter的时候，将item的ViewBinding填好后，可以直接操控item的控件，赋值，或者加载图片，所有简单的recycleview都可以直接通用，设计非常的银杏，十分好用

BaseAdapter<String, ItemDeviceBinding> adapter = new BaseAdapter<String, ItemDeviceBinding>(aa) {
            @Override
            protected void onBindingData(BaseHolder<ItemDeviceBinding> holder, String s, int position) {
                holder.getViewBinding().tvName.setText("123");

            }

            @Override
            protected ItemDeviceBinding onBindingView(ViewGroup viewGroup) {
                ItemDeviceBinding viewBinding = ItemDeviceBinding.inflate(LayoutInflater.from(viewGroup.getContext()), viewGroup, false);
                return viewBinding;
            }
        };
