實(shí)現(xiàn)拖拽

• 繼承BaseItemDraggableAdapter

// 適配器繼承
public class EditDataCenterAdapter extends BaseItemDraggableAdapter<Bean, BaseViewHolder>{
}

// 代碼中設(shè)置綁定適配器
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);
// 設(shè)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) {
    }
};

實(shí)現(xiàn)多布局

• 適配器Bean實(shí)現(xiàn)MultiItemEntity， 實(shí)現(xiàn)方法，根據(jù)后臺(tái)返回type值

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

• 適配器繼承BaseMultiItemQuickAdapter

// 構(gòu)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要與適配器Bean中g(shù)etItemType()返回的對(duì)應(yīng)
            addItemType(type1, R.layout.item_layout1);
            addItemType(type2, R.layout.item_layout2);
            addItemType(type3, R.layout.item_layout3);
     }
}

• 代碼中綁定適配器

CustomFieldAdapter  mAdapter = new CustomFieldAdapter (mList);
mAdapter.setOnItemChildClickListener(this);
mRvList.setLayoutManager(new LinearLayoutManager(this));
mRvList.setAdapter(mBaseCustomFieldAdapter);
// 拿到新數(shù)據(jù)之后綁定數(shù)據(jù)
mAdapter.setNewData(mList);
