Отправить список переработчиков в другой класс

/ 27 мая 2019

Я работаю в приложении Android, используя Android Studio, я использую классы Viewpager, чтобы показать данные.Что я хочу сделать, так это, когда я нажимаю на элемент во втором пейджере представления, который содержит список переработчиков, его данные загружаются в третий класс ViewViewpager.

Для достижения этого я создал класс Viewpager иТакже создан Адаптер Recycler для третьего класса.

Я показал один Элемент данных из класса firstviewpager в третий View-pager, как это, Создание метода в основном Activity, который содержит три класса Viewpager:1006 * 

public void selectTab(int position, String fname) {
    initialize();
    this.fname = fname;
    viewPager.setCurrentItem(position);
}

public String getMyData() {
    return fname;
}

Получение первого метода во втором классе адаптера Viewpager и вышеупомянутого второго метода в третий класс Viewpager Вот так .. 

MainFragment activity = (MainFragment) getActivity();
String name = activity.getMyData();
EdtName.setText(name);

Теперь я хочу то же самое, но хочукогда я нажимаю на Список утилизатора во втором классе Viewpager, его данные загружаются в третий список переработчика Viewpager.

Я реализовал адаптер Recycler для третьего Viewpager, как это .. 

public class InvoicesRecyclerAdapter extends RecyclerView.Adapter<InvoicesRecyclerAdapter.ClientViewHolder> {

private List<GetSetProductsDetail> listProduct;
Context mContext;
RecyclerView mRecyclerView;
View itemView;

public InvoicesRecyclerAdapter(List<GetSetProductsDetail> listProduct, RecyclerView recyclerView) {
    this.listProduct =  listProduct;
    mRecyclerView = recyclerView;
}


@Override
public ClientViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    mContext = parent.getContext();
    itemView = LayoutInflater.from(parent.getContext())
            .inflate(R.layout.items_invoice, parent, false);

    return new ClientViewHolder(itemView);
}


public class ClientViewHolder extends RecyclerView.ViewHolder {

    public TextView lblPName;
    public TextView lblRetail;
    RelativeLayout layout;

    public ClientViewHolder(View view) {
        super(view);


        lblPName =  view.findViewById(R.id.lblInvoicePName);
        lblRetail =  view.findViewById(R.id.lblInvoiceRetail);
        layout = view.findViewById(R.id.listinvoice);
    }
}

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

    MainFragment activityprodinvoice = (MainFragment) mContext;
    String namebltp = activityprodinvoice.getMyProdData();
    holder.lblPName.setText(namebltp);
    //holder.lblPName.setText(listProduct.get(position).getNAME());
    //holder.lblRetail.setText(listProduct.get(position).getRETAIL());
    holder.layout.setOnLongClickListener(new View.OnLongClickListener() {
        @Override
        public boolean onLongClick(View v) {
           // displayingAlertDialog(position);
            return false;
        }
    });
}

@Override
public int getItemCount() {
    Log.v(InvoicesRecyclerAdapter.class.getSimpleName(), "" + listProduct.size());
    return listProduct.size();
  }
}

Вот мой третий класс Viewpager 

public class Invoices extends Fragment {

TextView EdtName;
EditText EditCurrDate;
EditText EdtCurrDate2;
RecyclerView recyclerViewProdInvoice;
InvoicesRecyclerAdapter invoicesRecyclerAdapter;
List<GetSetProductsDetail> listproductsInvoices;
TextView EdtNameProdInvoiuce;
DatabaseHelper databaseHelper;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    final View view = inflater.inflate(R.layout.invoice, container, false);

    listproductsInvoices = new ArrayList<>();
    recyclerViewProdInvoice=view.findViewById(R.id.recyclerviewinvoicesprod);


    invoicesRecyclerAdapter = new InvoicesRecyclerAdapter(listproductsInvoices,recyclerViewProdInvoice);
    recyclerViewProdInvoice.setItemAnimator(new DefaultItemAnimator());
    recyclerViewProdInvoice.setItemAnimator(new DefaultItemAnimator());
    recyclerViewProdInvoice.setLayoutManager(new LinearLayoutManager(getContext()));
    recyclerViewProdInvoice.setHasFixedSize(true);
    recyclerViewProdInvoice.setAdapter(invoicesRecyclerAdapter);

    databaseHelper = new DatabaseHelper(getActivity());



    String date_n = new SimpleDateFormat("MMM / dd / yyyy", Locale.getDefault()).format(new Date());

    EditCurrDate = view.findViewById(R.id.currdate);
    EdtCurrDate2 = view.findViewById(R.id.currdate1);
    EdtName = view.findViewById(R.id.txtclientname);
    EdtNameProdInvoiuce = view.findViewById(R.id.edtprodinvoice);

    MainFragment activity = (MainFragment) getActivity();
    String name = activity.getMyData();
    EdtName.setText(name);

    MainFragment activityprodinvoice = (MainFragment) getActivity();
    String namebltp = activityprodinvoice.getMyProdData();
    EdtNameProdInvoiuce.setText(namebltp);

    EdtNameProdInvoiuce.setOnLongClickListener(new View.OnLongClickListener() {
        @Override
        public boolean onLongClick(View v) {
            AlertDialog.Builder builder = new AlertDialog.Builder(getContext());
            builder.setTitle("Choose Option");
            builder.setMessage("Are You Sure You Want To Add New Product?");
            builder.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    MainFragment main = (MainFragment) getActivity();
                    main.fromThirdToSecond(1);
                    dialog.cancel();

                }
            });
            builder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    dialog.dismiss();
                }
            });
            AlertDialog alert11 = builder.create();
            alert11.show();
            return false;
        }
    });

    EdtName.setOnLongClickListener(new View.OnLongClickListener() {
        @Override
        public boolean onLongClick(View v) {
            AlertDialog.Builder builder = new AlertDialog.Builder(getContext());
            builder.setTitle("Choose Option");
            builder.setMessage("Are You Sure You Want To Add New Client?");
            builder.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {

                    main.fromThirdToSecond(0);
                    dialog.cancel();

                }
            });
            builder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    dialog.dismiss();
                }
            });
            AlertDialog alert11 = builder.create();
            alert11.show();
            return false;
        }

    EditCurrDate.setText(date_n);

    EdtCurrDate2.setText(date_n);

    EditCurrDate.setOnClickListener(new View.OnClickListener() {

            int month = mcurrentDate.get(Calendar.MONTH);
            int day = mcurrentDate.get(Calendar.DAY_OF_MONTH);

            DatePickerDialog mDatePicker = new DatePickerDialog(getActivity(), new DatePickerDialog.OnDateSetListener() {

                    // TODO Auto-generated method stub

                    Log.e("Date Selected", "Month: " + selectedMonth + " Day: " + selectedDay + " Year: " + selectedYear);
                    EditCurrDate.setText((selectedMonth + 1) + "/" + selectedDay + "/" + selectedYear);
                }
            }, year, month, day);
            mDatePicker.setTitle("Select date");
            mDatePicker.show();

    });

    EdtCurrDate2.setOnClickListener(new View.OnClickListener() {

Вот мой основной вид деятельности 

public class MainFragment extends AppCompatActivity {
DatabaseHelper databaseHelper;
ViewPager viewPager;
String fname;
String namebltp;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main_fragment);
    initialize();

    databaseHelper = new DatabaseHelper(this);
    Toolbar toolbar = findViewById(R.id.toolbar);
    toolbar.setTitle("Dynamic ERPMini");

    TabLayout tabLayout = findViewById(R.id.tab_layout);

    tabLayout.addTab(tabLayout.newTab().setText("Clients"));
    tabLayout.addTab(tabLayout.newTab().setText("Products"));
    tabLayout.addTab(tabLayout.newTab().setText("Invoices"));

    tabLayout.setTabGravity(TabLayout.GRAVITY_FILL);

    final PagerAdapter adapter = new PagersAdapter(getSupportFragmentManager(), tabLayout.getTabCount());

    viewPager.setAdapter(adapter);

    viewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));

    tabLayout.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {

        @Override
        public void onTabSelected(TabLayout.Tab tab) {
            viewPager.setCurrentItem(tab.getPosition());
        }

        @Override
        public void onTabUnselected(TabLayout.Tab tab) {

        }

        @Override
        public void onTabReselected(TabLayout.Tab tab) {

        }
    });
}

public void initialize() {
    viewPager = findViewById(R.id.pager);
}

@Override
public void onResume() {
    super.onResume();
    viewPager = findViewById(R.id.pager);
}

public void fromThirdToSecond(int position) {
    initialize();
    viewPager.setCurrentItem(position);
}


public void selectTab(int position, String fname) {
    initialize();
    this.fname = fname;
    viewPager.setCurrentItem(position);
}

public String getMyData() {
    return fname;
}

public void selectTabProd(int position, String namebltp) {
    initialize();
    this.namebltp = namebltp;
    viewPager.setCurrentItem(position);
}

public String getMyProdData() {
    return namebltp;
 }

}

Я могу поделиться кодом для беттПонимание.
