Question

我们是Android编码的新手，我在这里和YouTube上都尝试了所有可能的解决方案，但仍然很挣扎。我们只想在单击recyclerview中的对话框中的按钮时将另一个选项卡的详细信息与另一个选项卡进行匹配。我们的学生旨在开发一款可帮助当地渔民的应用程序。：）

Here是我们要做的。

我们要在单击“设置参数”按钮后更改与对话框匹配的名称

这是我们在网上发现的，不同之处在于我们有一个对话框按钮

这是代码

RecyclerViewAdapter.java

template<class type, std::size_t capacaty>
class StaticVector {
    private:
        type arr[capacaty];
        std::size_t m_size;
    public:
        StaticVector() : m_size(0) {}

        type at(std::size_t index) {
            if (index >=0 && index < m_size) {
                return arr[index];
            }

            return type();
        }

        void remove(std::size_t index) {
            if (index >=0 && index < m_size) {
                for (std::size_t i=index; i < m_size-1; i++) {
                    arr[i] = arr[i+1];
                }
                m_size--;
            }
        }

        void push_back(type val) {
            if (m_size < capacaty) {
                arr[m_size] = val;
                m_size++;
            }
        }

        std::size_t size() {
            return m_size;
        }
};

“概述代码”标签（此标签我们要与之匹配）

public class RecyclerViewAdapter extends RecyclerView.Adapter<RecyclerViewAdapter.MyViewHolder> {

Context mContext;
List<specieList> mData;
Dialog myDialog;

public RecyclerViewAdapter(Context mContext, List<specieList> mData) {
    this.mContext = mContext;
    this.mData = mData;
}


@Override
public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {

    View v;
    Button b;

    v = LayoutInflater.from(mContext).inflate(R.layout.row,parent,false);
    final MyViewHolder vHolder = new MyViewHolder(v);

    myDialog = new Dialog(mContext);
    myDialog.setContentView(R.layout.fishpop);
    myDialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
    b = myDialog.findViewById(R.id.toasted);
    b.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            TextView toastfish = (TextView) myDialog.findViewById(R.id.dialog_fish_id);
            Toast.makeText(mContext,"Parameters are now set for " + toastfish.getText().toString(), Toast.LENGTH_SHORT).show();
            // here upon clicking this button click we want to match the details in this dialog to another tab.
        }
    });



    vHolder.fish_choices.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            TextView dialog_fish = (TextView) myDialog.findViewById(R.id.dialog_fish_id);
            TextView dialog_sciname = (TextView) myDialog.findViewById(R.id.dialog_sciname_id);
            ImageView dialog_image = (ImageView) myDialog.findViewById(R.id.dialog_image_id);
            dialog_fish.setText(mData.get(vHolder.getAdapterPosition()).getFish());
            dialog_sciname.setText(mData.get(vHolder.getAdapterPosition()).getSciname());
            dialog_image.setImageResource(mData.get(vHolder.getAdapterPosition()).getImage());
            myDialog.show();
        }
    });
    return vHolder;
}

@Override
public void onBindViewHolder(MyViewHolder holder, int position) {

    holder.tv_fish.setText(mData.get(position).getFish());
    holder.tv_sciname.setText(mData.get(position).getSciname());
    holder.img.setImageResource(mData.get(position).getImage());

}


@Override
public int getItemCount() {
    return mData.size();
}

public static class MyViewHolder extends RecyclerView.ViewHolder {

    private LinearLayout fish_choices;
    private TextView tv_fish;
    private TextView tv_sciname;
    private ImageView img;

    public MyViewHolder(View itemView) {
        super(itemView);
            fish_choices = (LinearLayout) itemView.findViewById(R.id.choices);
            tv_fish = (TextView) itemView.findViewById(R.id.textView1);
            tv_sciname = (TextView) itemView.findViewById(R.id.textView2);
            img = (ImageView) itemView.findViewById(R.id.image);

    }
}
}

“币种”标签的代码（我们要引用此标签）

public class overview extends Fragment {

View v2;


// TODO: Rename parameter arguments, choose names that match
// the fragment initialization parameters, e.g. ARG_ITEM_NUMBER
private static final String ARG_PARAM1 = "param1";
private static final String ARG_PARAM2 = "param2";

// TODO: Rename and change types of parameters
private String mParam1;
private String mParam2;

private OnFragmentInteractionListener mListener;

public overview() {
    // Required empty public constructor
}

/**
 * Use this factory method to create a new instance of
 * this fragment using the provided parameters.
 *
 * @param param1 Parameter 1.
 * @param param2 Parameter 2.
 * @return A new instance of fragment overview.
 */
// TODO: Rename and change types and number of parameters
public static overview newInstance(String param1, String param2) {
    overview fragment = new overview();
    Bundle args = new Bundle();
    args.putString(ARG_PARAM1, param1);
    args.putString(ARG_PARAM2, param2);
    fragment.setArguments(args);
    return fragment;
}

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    if (getArguments() != null) {
        mParam1 = getArguments().getString(ARG_PARAM1);
        mParam2 = getArguments().getString(ARG_PARAM2);
    }
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    v2 = inflater.inflate(R.layout.fragment_overview, container, false);
    Calendar calendar = Calendar.getInstance();
    SimpleDateFormat time = new SimpleDateFormat("HH:mm:ss");
    String currentDate = DateFormat.getDateInstance(DateFormat.FULL).format(calendar.getTime());
    String currentTime = time.format(calendar.getTime());


    TextView textViewDate =(TextView) v2.findViewById(R.id.date_id);
    textViewDate.setText(currentDate);
    TextView textViewTime =(TextView) v2.findViewById(R.id.time_id);
    textViewTime.setText(currentTime);



    return v2;
}

// TODO: Rename method, update argument and hook method into UI event
public void onButtonPressed(Uri uri) {
    if (mListener != null) {
        mListener.onFragmentInteraction(uri);
    }
}

@Override
public void onAttach(Context context) {
    super.onAttach(context);
    if (context instanceof OnFragmentInteractionListener) {
        mListener = (OnFragmentInteractionListener) context;
    } else {
        throw new RuntimeException(context.toString()
                + " must implement OnFragmentInteractionListener");
    }
}

@Override
public void onDetach() {
    super.onDetach();
    mListener = null;
}

public interface OnFragmentInteractionListener {
    // TODO: Update argument type and name
    void onFragmentInteraction(Uri uri);
}
}

java-单击另一个选项卡的RecycleView中的对话框按钮后，匹配选项卡的内容
