java - 如何在回收 View 中隐藏部分字符串？

Question

我有一个 recyclerview，其中显示一个字符串，其中包含 id、姓名和联系电话作为单个字符串。我想隐藏字符串中的 id。我使用以下代码将字符串添加到数组列表。我在 TextView 中显示连接的字符串，例如 (1-XYZ 0123456789)

   private void showGuestDetails(String response) {
        Guest_info guest_info = new Guest_info(response);
        guest_info.ParseGuestInfo();

        String guestid[] = guest_info.guest_id;

        for (int i = 0; i < guestid.length; i++) {
            list.add(guest_info.guest_id[i] + "-" + guest_info.guest_name[i] + "  " + guest_info.guest_mobile[i]);

        }
    }

这是我正在使用的适配器类:-

public class GuestAdapter extends RecyclerView.Adapter<GuestAdapter.GuestViewHolder> {

    private List<String> list_item ;
    public Context mcontext;
    private BookingActivity bookingActivity;


    public GuestAdapter(List<String> list, Context context, BookingActivity bookingActivity) {

        list_item = list;
        mcontext = context;
        this.bookingActivity =bookingActivity;
    }

    // Called when RecyclerView needs a new RecyclerView.ViewHolder of the given type to represent an item.
    @Override
    public GuestAdapter.GuestViewHolder onCreateViewHolder(ViewGroup parent,
                                                         int viewType) {
        // create a layout
        View view = LayoutInflater.from(parent.getContext()).inflate(
                R.layout.list_item, null);

        GuestViewHolder myViewHolder = new GuestViewHolder(view);
        return myViewHolder;
    }

    // Called by RecyclerView to display the data at the specified position.
    @Override
    public void onBindViewHolder(final GuestViewHolder viewHolder, final int position ) {


        viewHolder.guest_name.setText(list_item.get(position));

        viewHolder.guest_name.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {



              bookingActivity.setGuestText(list_item.get(position));


            }
        });

    }

    //Returns the total number of items in the data set hold by the adapter.
    @Override
    public int getItemCount() {
        return list_item.size();
    }


    // initializes textview in this class
    public static class GuestViewHolder extends RecyclerView.ViewHolder {

        public TextView guest_name;

        public GuestViewHolder(View itemLayoutView) {
            super(itemLayoutView);

            guest_name = (TextView) itemLayoutView.findViewById(R.id.guestName);

        }
    }
}

Is there a way by which I will be able to display everything after the hyphen and hide everything before the hyphen including the hyphen. Any help or suggestion is appreciated. Thank you.

你的情况很好，但是在字符串列表的地方，只需传递(Guest_info类)的完整对象列表，并像这样更新你的适配器

public class GuestAdapter extends RecyclerView.Adapter<GuestAdapter.GuestViewHolder> {

//private List<String> list_item ;
private List<Guest_info> list_item ;
public Context mcontext;
private BookingActivity bookingActivity;


public GuestAdapter(List<Guest_info> list, Context context, BookingActivity bookingActivity) {

    list_item = list;
    mcontext = context;
    this.bookingActivity =bookingActivity;
}

// Called when RecyclerView needs a new RecyclerView.ViewHolder of the given type to represent an item.
@Override
public GuestAdapter.GuestViewHolder onCreateViewHolder(ViewGroup parent,
                                                     int viewType) {
    // create a layout
    View view = LayoutInflater.from(parent.getContext()).inflate(
            R.layout.list_item, null);

    GuestViewHolder myViewHolder = new GuestViewHolder(view);
    return myViewHolder;
}

// Called by RecyclerView to display the data at the specified position.
@Override
public void onBindViewHolder(final GuestViewHolder viewHolder, final int position ) {

    Guest_info bean = list_item.get(position);
    viewHolder.guest_name.setText(bean.getGuest_name());

    viewHolder.guest_name.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
          bookingActivity.setGuestText(bean.getGuest_name());
        }
    });

}

//Returns the total number of items in the data set hold by the adapter.
@Override
public int getItemCount() {
    return list_item.size();
}


// initializes textview in this class
public static class GuestViewHolder extends RecyclerView.ViewHolder {

    public TextView guest_name;

    public GuestViewHolder(View itemLayoutView) {
        super(itemLayoutView);
        guest_name = (TextView) itemLayoutView.findViewById(R.id.guestName);
    }
}
}

这样你就可以显示任何你想要的数据，你不需要对字符串进行操作，并且可以获得完整的数据。
