要先学会正视自己，再学会审视问题；然后，找一个平衡点，至少让自己体面一点。一味的心不甘情不愿，除了折磨自己，根本没有任何意义

具体实现

第一步：MyExpandableListView

      public class MyExpandableListView extends BaseExpandableListAdapter {
private Context mContext;
private List<String> mGroup;
private Boolean isSelect = false;
private List<List<Inf_Area.ResultBean.TblFreightCityiesInfoBean>> mItemList;
int item = 0;
private final LayoutInflater mInflater;
private List<Inf_Area.ResultBean.TblFreightCityiesInfoBean> getList;
private ExpandableListView mRv;
private onItemShowListener mOnItemShowListener;
private LabelsView mLabelsView;
private ArrayList<LabelsView> mLabelsViews = new ArrayList<>();
private List<Integer> mInteger = new ArrayList<>();
private String type;
private OnData mDataListener;

ArrayList<String> list = new ArrayList<>();

public MyExpandableListView(Context mContext, List<String> mGroup, List<List<Inf_Area.ResultBean.TblFreightCityiesInfoBean>> mItemList, ExpandableListView rv) {
    this.mContext = mContext;
    this.mGroup = mGroup;
    this.mItemList = mItemList;
    this.mInflater = LayoutInflater.from(mContext);
    this.mRv = rv;
}

public void setData(List<Inf_Area.ResultBean.TblFreightCityiesInfoBean> getList) {
    this.getList = getList;

}

@Override
public int getGroupCount() {
    return mGroup.size();
}

@Override
public int getChildrenCount(int groupPosition) {
    return 1;
}

@Override
public Object getGroup(int groupPosition) {
    return mGroup.get(groupPosition);
}

@Override
public Object getChild(int groupPosition, int childPosition) {
    return mItemList.get(groupPosition).get(childPosition);
}

@Override
public long getGroupId(int groupPosition) {
    return groupPosition;
}

@Override
public long getChildId(int groupPosition, int childPosition) {
    return childPosition;
}

@Override
public boolean hasStableIds() {
    return false;
}

@Override
public View getGroupView(final int groupPosition, boolean isExpanded, View convertView, ViewGroup parent) {
//        convertView = mInflater.inflate(R.layout.child_item, null);
//        }
    if (convertView == null) {
        convertView = mInflater.inflate(R.layout.group_item, null);
    }
    String group = mGroup.get(groupPosition);
    TextView tvGroup = (TextView) convertView.findViewById(R.id.location);
    tvGroup.setText(group);

    return convertView;
}


@Override
public View getChildView(int groupPosition, int childPosition, boolean isLastChild, View convertView, ViewGroup parent) {
    List<Inf_Area.ResultBean.TblFreightCityiesInfoBean> infoBeans = mItemList.get(groupPosition);

    if (convertView == null) {
        convertView = mInflater.inflate(R.layout.child_item, null, false);
    }
    RecyclerView recyclerView = convertView.findViewById(R.id.recy);
    recyclerView.setLayoutManager(new GridLayoutManager(mContext,4));
    Rlv_Adapter rlv_freightItem = new Rlv_Adapter(infoBeans,mItemList, groupPosition);
    recyclerView.setAdapter(rlv_freightItem);
    rlv_freightItem.setOnItemShowListener(new Rlv_Adapter.onItemShowListener() {
        @Override
        public void OnItemShow(int position, TextView holder1) {
            // boolean status = mTblFreightCityiesInfoBeans.get(position).isStatus();
            for (int i = 0; i <infoBeans.size() ; i++) {
                boolean isSelect = infoBeans.get(i).isIsSelect();
                if (isSelect) {
                    if (i!=position) {
                        infoBeans.get(i).setIsSelect(false);
                        notifyDataSetChanged();
                    }

                }
            }
            boolean isSelect = infoBeans.get(position).isIsSelect();
            Log.v("xue","点击时候的 是true 还是false-==============="+isSelect);
            if (isSelect) {
                holder1.setTextColor(Color.parseColor("#6B6B6B"));
                infoBeans.get(position).setIsSelect(false);
            }else {
                //红色
                holder1.setTextColor(Color.parseColor("#E53030"));
                infoBeans.get(position).setIsSelect(true);
            }
            for (int i = 0; i <mItemList.size() ; i++) {
                for (int j = 0; j <mItemList.get(i).size() ; j++) {
                    if (position!=j) {
                            holder1.setTextColor(Color.parseColor("#6B6B6B"));
                           mItemList.get(i).get(j).setIsSelect(false);
                            notifyDataSetChanged();


                    }


                }

            }

        }

    });
    return convertView;
}


public interface OnData {
    void getdata(String list, int poistion);
}

public void setOnDataListener(OnData onDataListener) {
    this.mDataListener = onDataListener;
}

//子项是否可选中,如果要设置子项的点击事件,需要返回true
@Override
public boolean isChildSelectable(int groupPosition, int childPosition) {
    return true;
}

public interface onItemShowListener {
    void OnItemShow(int position);
}

public void setOnItemShowListener(onItemShowListener listener) {
    mOnItemShowListener = listener;
}

  }

第二步：Rlv_Adapter

 public class Rlv_Adapter extends RecyclerView.Adapter {
private ArrayList<Inf_Area.ResultBean.TblFreightCityiesInfoBean> mTblFreightCityiesInfoBeans;
private Context mContext;
private List<List<Inf_Area.ResultBean.TblFreightCityiesInfoBean>> mItemList;
int chouPostion;

private onItemShowListener mOnItemShowListener;

public Rlv_Adapter(List<Inf_Area.ResultBean.TblFreightCityiesInfoBean> tblFreightCityiesInfoBeans, List<List<Inf_Area.ResultBean.TblFreightCityiesInfoBean>> mItemList, int postion ) {

    this.mTblFreightCityiesInfoBeans = (ArrayList<Inf_Area.ResultBean.TblFreightCityiesInfoBean>) tblFreightCityiesInfoBeans;
    this.mItemList=mItemList;
    this.chouPostion=postion;
}

@NonNull
@Override
public RecyclerView.ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
    mContext = parent.getContext();
    View inflate = LayoutInflater.from(mContext).inflate(R.layout.recy_item, null);

    return new OneViewHolder(inflate);
}

@Override
public void onBindViewHolder(@NonNull RecyclerView.ViewHolder holder, int position) {

    boolean isSelect = mTblFreightCityiesInfoBeans.get(position).isIsSelect();
    Log.v("xue","未点击时候的 是true 还是false-==============="+isSelect);
    OneViewHolder holder1 = (OneViewHolder) holder;
    if (isSelect) {
        //红色
        holder1.mLocation.setTextColor(Color.parseColor("#E53030"));
    }else {
        //恢复
        holder1.mLocation.setTextColor(Color.parseColor("#6B6B6B"));
    }
    holder1.mLocation.setText(mTblFreightCityiesInfoBeans.get(position).getCity());
    holder1.mLocation.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            mOnItemShowListener.OnItemShow(position,holder1.mLocation);
        }

    });


}

@Override
public int getItemCount() {
    return mTblFreightCityiesInfoBeans.size();
}
static class OneViewHolder extends RecyclerView.ViewHolder {

    private final TextView mLocation;

    public OneViewHolder(View itemView) {
        super(itemView);
        mLocation = itemView.findViewById(R.id.te_revy);


    }
}
public interface onItemShowListener {
    void OnItemShow(int position,TextView textView);
}

public void setOnItemShowListener(onItemShowListener listener) {
    mOnItemShowListener = listener;
}

}
