BaseQuickAdapter实现拖拽排序或多布局

实现拖拽

• 继承BaseItemDraggableAdapter

// 适配器继承
public class EditDataCenterAdapter extends BaseItemDraggableAdapter<Bean, BaseViewHolder>{
}

// 代码中设置绑定适配器
mAdapter = new EditDataCenterAdapter(mList);
mRvList.setLayoutManager(new LinearLayoutManager(this));
mRvList.setAdapter(mAdapter);

ItemDragAndSwipeCallback itemDragAndSwipeCallback = new ItemDragAndSwipeCallback(mAdapter);
ItemTouchHelper itemTouchHelper = new ItemTouchHelper(itemDragAndSwipeCallback);
itemTouchHelper.attachToRecyclerView(mRvList);
// 设置可拖拽(rl_layout: item的根布局id)
mAdapter.enableDragItem(itemTouchHelper, R.id.rl_layout, true);
mAdapter.setOnItemDragListener(onItemDragListener);

• onItemDragListener

OnItemDragListener onItemDragListener = new OnItemDragListener() {
    @Override
    public void onItemDragStart(RecyclerView.ViewHolder viewHolder, int pos) {
    }

    @Override
    public void onItemDragMoving(RecyclerView.ViewHolder source, int from, RecyclerView.ViewHolder target, int to) {
    }

    @Override
    public void onItemDragEnd(RecyclerView.ViewHolder viewHolder, int pos) {
    }
};

实现多布局

• 适配器Bean实现MultiItemEntity， 实现方法，根据后台返回type值

public static class AdapterBean implements MultiItemEntity {
      @Override
      public int getItemType() {
            return type;
      }
}

• 适配器继承BaseMultiItemQuickAdapter

// 构造方法中添加多布局
public class CustomFieldAdapter extends BaseMultiItemQuickAdapter<AdapterBean , BaseViewHolder> {
    public CustomFieldAdapter(List<CustomFieldVO.CustomFieldListBean> data) {
            super(data);
            // type1 2 3要与适配器Bean中getItemType()返回的对应
            addItemType(type1, R.layout.item_layout1);
            addItemType(type2, R.layout.item_layout2);
            addItemType(type3, R.layout.item_layout3);
     }
}

• 代码中绑定适配器

CustomFieldAdapter  mAdapter = new CustomFieldAdapter (mList);
mAdapter.setOnItemChildClickListener(this);
mRvList.setLayoutManager(new LinearLayoutManager(this));
mRvList.setAdapter(mBaseCustomFieldAdapter);
// 拿到新数据之后绑定数据
mAdapter.setNewData(mList);
