RecyclerView嵌套RecyclerView使用的问题

项目需求：公司出的项目需求是个预约系统，从周一到周天每天的预约情况，一天的预约中：每个节目使用的时间长短所占用的比例高度是不一样的，中间的间隔也是不一样的，总之根据需求可以自己定相关的距离。

上代码：

一：外层想直接用RecyclerView来实现GridView的模块功能，就用了GridManager

GridLayoutManager manager = new GridLayoutManager(this,7);

但是！！！！！后期调整的时候竟然发现里面的RecyclerView不能滑动！！！！！！！！然后各种搜材料，什么事件分发

addOnItemTouchListener中的拦截，自定义RecyclerView强制下发不消费，都不行，所以这个坑要注意，有大佬知道什么愿意欢迎讨论。

recyclerView.setNestedScrollingEnabled(true);这个属性还是要设置的，允许嵌套滑动。

外层Adapter

public class MyRecyclerAdapter extends RecyclerView.Adapter<MyRecyclerAdapter.ViewHolder>{
    private List<WeekBean> mList;
    private Context context;

    public MyRecyclerAdapter(List<WeekBean> mList, Context context) {
        this.mList = mList;
        this.context = context;
    }

    @NonNull
    @Override
    public ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int i) {
        return new ViewHolder(LayoutInflater.from(context).inflate(R.layout.main_recycler_item,parent,false));
    }

    @Override
    public void onBindViewHolder(@NonNull ViewHolder holder, int i) {
        ViewHolder viewHolder= (ViewHolder) holder;
        if(mList!=null&&mList.size()>0){
            WeekBean weekBean = mList.get(i);
            if(weekBean!=null){//这里是对子Adapter进行初始化
                viewHolder.textView.setText(weekBean.getTime());
                List<WeekBeans> list = weekBean.getList();
                RecyclerItemAdapter recyclerAdapter = new RecyclerItemAdapter(context,list);
                viewHolder.recyclerView.setAdapter(recyclerAdapter);
                LinearLayoutManager linearLayoutManager=new LinearLayoutManager(context, LinearLayoutManager.VERTICAL,false);
                viewHolder.recyclerView.setLayoutManager(linearLayoutManager);
            }
        }
    }

    @Override
    public int getItemCount() {
        return 7;//因为我就7条所以就写死了7条
    }

    class ViewHolder extends RecyclerView.ViewHolder {
        TextView textView;
        RecyclerView recyclerView;
        public ViewHolder(@NonNull View itemView) {
            super(itemView);
            textView = itemView.findViewById(R.id.item_time);
            recyclerView = itemView.findViewById(R.id.item_recycler);
        }
    }

 

二：子Adapter

public class RecyclerItemAdapter extends RecyclerView.Adapter<RecyclerItemAdapter.ViewHolder> {

    List<WeekBeans> mList_item;
    Context context;
    private WeekBeans mWeekBeans = null;//中间替换使用
    private int num = 0,marnum = 0;//占用多高，距离上一个多高

    public RecyclerItemAdapter(Context context,List<WeekBeans> mList_item) {
        this.context = context;
        this.mList_item = mList_item;
    }

    @NonNull
    @Override
    public ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        return new ViewHolder(LayoutInflater.from(context).inflate(R.layout.item_recycler_item, parent, false));
    }

    @Override
    public void onBindViewHolder(@NonNull ViewHolder holder, int position) {
        WeekBeans weekBeans = mList_item.get(position);
        TextView textView = holder.textItem;
        num = TimeVIewUtils.GetTextNum(weekBeans.getStart_at(),weekBeans.getEnd_at());
        if(position>0){
            mWeekBeans = mList_item.get(position-1);
        }
        if(mWeekBeans!=null){
            marnum = TimeVIewUtils.GetTextDistence(weekBeans.getStart_at(),mWeekBeans.getEnd_at());
        }else {
            marnum = TimeVIewUtils.GetTextDistence_NullLast(weekBeans.getStart_at());
        }
        String message = TimeVIewUtils.GetTextMessage(weekBeans.getStart_at(),weekBeans.getEnd_at(),weekBeans.getTitle());
        TimeVIewUtils.SetTextView(context,textView, num, marnum, message, position);
    }

    @Override
    public int getItemCount() {
        return mList_item!=null?mList_item.size():0;
    }
    class ViewHolder extends RecyclerView.ViewHolder {
        TextView textItem;

        ViewHolder(View view) {
            super(view);
            textItem = view.findViewById(R.id.item_recycler_item_text);
        }
    }
}

 

三：各种计算方法

//获取份额
public static int GetTextNum(String start_at,String end_at){
    //"2020-04-29 10:00:00","2020-04-29 12:00:00",
    int num = 0;
    int start = Integer.parseInt(start_at.substring(11,13));
    int end = Integer.parseInt(end_at.substring(11,13));
    num = (end-start)*2;
    return num;
}

//获取距离上一个的距离
public static int GetTextDistence(String next_start_at,String last_end_at){
    int num = 0;
    int start = Integer.parseInt(next_start_at.substring(11,13));
    int end = Integer.parseInt(last_end_at.substring(11,13));
    num = (start-end)*2;
    return num;
}
public static int GetTextDistence_NullLast(String next_start_at){
    int num = 0;
    int start = Integer.parseInt(next_start_at.substring(11,13));
    int end = 8;
    num = (start-end)*2;
    return num;
}

//对TextView的动态设置
public static TextView SetTextView(Context context,TextView textView,int num,int martop,String message,int color){
    int top = 0;
    child_height = 826/28;
    int text_height = 0;
    if(num>5){
        text_height = num*child_height;
    }else {
        text_height = 4*child_height;
    }
    if(martop>5){//8
        top = 10*child_height;//8
    }else if(martop==0){
        top=9;
    }else {
        top = martop*child_height;
    }
    textView.setGravity(Gravity.CENTER);
    textView.setText(message);
    textView.setMaxLines(3);
    textView.setEllipsize(TextUtils.TruncateAt.END);
    textView.setPadding(15,0,15,0);
    LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(232, text_height);
    params.setMargins(9,top, 9, 0);
    textView.setLayoutParams(params);
    if(color<4){
        textView.setBackgroundResource(colors[color]);
    }else {
        textView.setBackgroundResource(colors[color-4]);
    }
    textView.setTextColor(Color.WHITE);
    return textView;
}

 

另外还有一个字符串转星期几的Util

public static String getWeekDayNew(String time){
    String Week = "";
    SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd");// HH:mm:ss
    SimpleDateFormat sdf = new SimpleDateFormat("E");
    try{
        Date date = format.parse(time);
        Week = sdf.format(date);
    }catch (Exception e){
        e.printStackTrace();
    }
    return Week;
}

 

好了，有啥问题可以留言交流啊，希望大佬可以多多指点
