Android-Adapter

此项目已经废弃，最新项目为 https://github.com/naivor/recycler-adapter

---

简单易用的Android Adapter,包括RecyAdapter和ListAdapter,对于RecyclerView 和 AbsListView 提供一致的Adapter操作风格

现在可以使用在线库：

compile 'com.naivor:adapter:1.0.8'

RecyAdapter和ListAdapter都实现了AdapterOperator接口，实现了对Adapter数据的添加，删除，置换，清空的操作，如图

1. For RecyclerView，you should extends RecyAdapter

example:

public class TestRecyAdapter extends RecyAdapter<SimpleItem> {


    public TestRecyAdapter(Context context) {
        super(context);
    }


    @Override
    public RecyclerView.ViewHolder createHolder(View itemview, int viewType) {
        return new SHolder(itemview);
    }

    @Override
    public int getLayoutRes(int viewType) {
        return R.layout.list_item_txt;
    }

    static class SHolder extends RecyHolder<SimpleItem> {

        @Bind(R.id.tv_text)
        TextView tvText;

        public SHolder(View itemView) {
            super(itemView);

            ButterKnife.bind(this, itemView);

            registerClick(itemView);
        }

        @Override
        public void bindData(AdapterOperator<SimpleItem> operator, int position, SimpleItem itemData) {
            super.bindData(operator, position, itemData);

            tvText.setText(itemData.getContent() + "编号：" + position);
        }
      
    }
}

效果：

另外，RecyAdapter实现了HeaderFooter接口，支持对RecyclerView 添加Header，Footer

效果：

2. For AbsListView,you should extends ListAdapter

example:

public class TestListAdapter extends ListAdapter<SimpleItem> {

    public TestListAdapter(Context context) {
        super(context);
    }

   
    @Override
    public ListHolder<SimpleItem> onCreateViewHolder(View itemview, int viewType) {
        return new HomeViewHolder(itemview);
    }

  
    @Override
    public int getLayoutRes(int viewType) {
        return R.layout.list_item_txt;
    }

   
    static class HomeViewHolder extends ListHolder<SimpleItem> {

        @Bind(R.id.tv_text)
        TextView tvText;

        public HomeViewHolder(View convertView) {
            super(convertView);

            ButterKnife.bind(this, convertView);

        }

        @Override
        public void bindData(AdapterOperator<SimpleItem> operator, int position, SimpleItem itemData) {
            super.bindData(operator, position, itemData);

            tvText.setText(itemData.getContent() + "编号：" + position);
        }
    }

}

ListView 使用效果：

GridView 使用效果：

3. For Multiple Items

定义不同的ViewHolder:

static class AHolder extends RecyHolder<SimpleItem> implements View.OnClickListener {...}
static class BHolder extends RecyHolder<SimpleItem> implements View.OnClickListener {...}
static class SHolder extends RecyHolder<SimpleItem> implements View.OnClickListener {...}

对不同的ViewType进行处理：

 @Override
    public RecyclerView.ViewHolder createHolder(View itemview, int viewType) {

        switch (viewType) {
            case SimpleItem.Type.A:
                return new AHolder(itemview);
            case SimpleItem.Type.B:
                return new BHolder(itemview);
            case SimpleItem.Type.S:
                return new SHolder(itemview);
            default:
                return null;
        }
    }

    @Override
    public int getAdapterItemType(int position) {
        return getItem(position).getType();
    }

    /**
     * 获取布局资源
     *
     * @param viewType
     * @return
     */
    @Override
    public int getLayoutRes(int viewType) {
        switch (viewType) {
            case SimpleItem.Type.A:
                return R.layout.list_item_txt_a;
            case SimpleItem.Type.B:
                return R.layout.list_item_txt_b;
            case SimpleItem.Type.S:
                return R.layout.list_item_txt;
            default:
                return 0;
        }

    }

效果：

4. ItemView Event

ItemView 中的事件默认通过InnerListener回调到Activity或Fragment中处理，InnerListener默认提供了四种事件处理：

abstract class InnerListener<T> {
        public void onClick(View view, T itemData, int postition) {
        }
        public void onLongClick(View view, T itemData, int postition) {
        }

        public void onFocusChange(View view, boolean hasFocus, T itemData, int postition) {
        }

        public void onCheckedChanged(CompoundButton buttonView, boolean isChecked, T itemData, int postition) {
        }
    }

需要对某个view进行事件监听只需要注册相应的事件：

registerClick(View v)；
registerLongClick(View v)；
registerFocusChange(View v)；
registerCheckedChanged(CompoundButton v)

然后在Activity或Fragment中处理，也可以在ViewHolder中重写

     @Override
    public void onClick(View v) {
        //TODO 事件处理
    }

    @Override
    public boolean onLongClick(View v) {
        //TODO 事件处理
        return true;
    }

    @Override
    public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
       //TODO 事件处理
    }

    @Override
    public void onFocusChange(View v, boolean hasFocus) {
        //TODO 事件处理
    }

直接对事件进行处理。
