RecyclerView 경동 분류 연동 효과 구현

Adapter–ParentAdapter

public class ParentAdapter extends BaseQuickAdapter {

    public ParentAdapter(int layoutResId, @Nullable List data) {
        super(layoutResId, data);
    }

    @Override
    protected void convert(BaseViewHolder helper, final ParentBean.DataBean item) {
        helper.setText(R.id.textone, item.getName());
        helper.addOnClickListener(R.id.textone);
        // 
        helper.setOnClickListener(R.id.textone, new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                //     
                mItemClick.onItem(item.getCid());
            }
        });
    }

    // 
    private ItemClick mItemClick;

    // 
    public interface ItemClick {
        void onItem(int data);
    }

    // 
    public void setitemClick(ItemClick mItemClick) {
        this.mItemClick = mItemClick;
    }
}

어댑터 – ChildName어댑터 중첩 하위 어댑터

public class ChildAdapter extends BaseQuickAdapter {
