问题


I need to create recyclerview cardview in fragment from the data that is written in a DiagloFragment

What would you do? How can I create a recycler view with the list once I press the button "HECHO"?

IMAGE CAPTURE DATA

Can you explain to me what should I do or even post an example please (done by you or posted somewhere else)?

Beforehand thank you very much.

DialogFragment class:

   @Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
   // View v = inflater.inflate(R.layout.fragment_captura_dialog_act, container, false);
    View v = inflater.inflate(R.layout.frag_capactividades, container, false);
    Spinner spinnerA;
    spinnerA = (Spinner)v.findViewById(R.id.spinnerConf);
    bguardar = (Button) v.findViewById(R.id.bGuaradrPaga);
    codigo = (EditText) v.findViewById(R.id.tCodData) ;
    precio = (EditText) v.findViewById(R.id.tPrecioData);
    preciounidadextra = (EditText) v.findViewById(R.id.preciouextra);
    cantidadminima = (EditText) v.findViewById(R.id.tCanMinData);
    primadominical = (EditText) v.findViewById(R.id.tPrimaData);
    final String tipojornada = spinnerA.getSelectedItem().toString();
    bguardar.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            //Code create recyclerview
            empleado.guardaempleado(codigo.getText().toString(), precio.getText().toString(), preciounidadextra.getText().toString(), cantidadminima.getText().toString()
                    , primadominical.getText().toString(), tipojornada);
        }
    });

    return v;
}

}

 private void ShowMessage() {
        final String[] actividades = {"act1", "act2", "act3", "act4", "act5"};
        final int itemSelected = 0;
        new AlertDialog.Builder(getContext())
                .setTitle("Selecciona la actividad")
                .setSingleChoiceItems(actividades, itemSelected, new DialogInterface.OnClickListener() {
                    @Override

                    }
                })
                .show();

    }

CaptureDialog class:

public class CapturaDialogAct extends DialogFragment {
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
}
TextView textView;
Button bguardar;
EditText codigo,precio,preciounidadextra, cantidadminima,primadominical;
Adapter rvAdapter;
RecyclerView recyclerView;
private static RecyclerView.Adapter adapter;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
   // View v = inflater.inflate(R.layout.fragment_captura_dialog_act, container, false);
    View v = inflater.inflate(R.layout.frag_capactividades, container, false);
    Spinner spinnerA;
    spinnerA = (Spinner)v.findViewById(R.id.spinnerConf);
    bguardar = (Button) v.findViewById(R.id.bGuaradrPaga);
    codigo = (EditText) v.findViewById(R.id.tCodData) ;
    precio = (EditText) v.findViewById(R.id.tPrecioData);
    preciounidadextra = (EditText) v.findViewById(R.id.preciouextra);
    cantidadminima = (EditText) v.findViewById(R.id.tCanMinData);
    primadominical = (EditText) v.findViewById(R.id.tPrimaData);
    final String tipojornada = spinnerA.getSelectedItem().toString();
    bguardar.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            //Code create recyclerview
            empleado.guardaempleado(codigo.getText().toString(), precio.getText().toString(), preciounidadextra.getText().toString(), cantidadminima.getText().toString()
                    , primadominical.getText().toString(), tipojornada);
        }
    });

    return v;
}

}

Model:

    public class ActividadesModel implements Serializable {
    private String  codigo ,precio, preciounidadextra, cantidadminima, primadominical, tipojordana;
   public ActividadesModel( String precio, String preciounidadextra, String cantidadminima, String primadominical, String codigo, String tipojordana){
       this.codigo = codigo;
   }
    public String getCodigo()
   {
       return codigo;
   }
   public void setCodigo(String codigo){
       this.codigo = codigo;
   }

   public String getPrecio(){
       return precio;
   }

   public void setPrecio(){
       this.precio = precio;
   }

   public String getPreciounidadextra(){
       return preciounidadextra;
   }

   public void setPreciounidadextra(){
       this.preciounidadextra = preciounidadextra;
   }

   public String getCantidadminima(){
       return cantidadminima;
   }
   public void setCantidadminima(){
       this.cantidadminima = cantidadminima;
   }

   public String getPrimadominical(){
       return primadominical;
   }
   public void setPrimadominical(){
       this.primadominical = primadominical;
   }

   public String getTipojordana(){
       return tipojordana;
   }
   public void setTipojordana(){
       this.tipojordana = tipojordana;
   }
}

Add ADapter:

public class AdapterAct extends RecyclerView.Adapter<AdapterAct.MyViewHolder> implements Filterable {

private List<ActividadesModel> actividadesModelList = new ArrayList<>();
private Context context;

private List<ActividadesModel> actividadesArrayList;

private IAxiliarActividades iAxiliarActividades;

List<ActividadesModel> contactList;


public AdapterAct(Context context, List<ActividadesModel> listCont) {
    this.context = context;
    this.contactList = contactList;
}


@NonNull
@Override
public MyViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
   // return null;
    View v;
    v = LayoutInflater.from(context).inflate(R.layout.card_actividad, parent, false);
    MyViewHolder myViewHolder = new MyViewHolder(v);
    return myViewHolder;
}

public static class MyViewHolder extends RecyclerView.ViewHolder {

    TextView name;
    TextView precio;



    public MyViewHolder(View itemView) {
        super(itemView);

        name = (TextView) itemView.findViewById(R.id.txtNombreMostrar);
        precio = (TextView) itemView.findViewById(R.id.txtPrecioMostrar);

    }
}

@Override
public void onBindViewHolder(@NonNull MyViewHolder holder, int position) {
    //Codigo para crear el listado de acitividades

}

@Override
public int getItemCount() {
    return 0;
}

@Override
public Filter getFilter() {
    return null;
}

public class myViewHolder extends RecyclerView.ViewHolder {

    TextView nombre, precio;


    public myViewHolder(@NonNull View itemView) {
        super(itemView);
    }
}

}

Please follow below steps to create interface listener for the the DialogFragment input to be returned to your fragment.

  • Step 1: Create an interface inside the CapturaDialogAct DialogFragment, and an instance field of it:
  • Step 2: Modify the CapturaDialogAct to accept an argument of this interface
  • Step 3: Trigger the interface method whenever you click the DialogFragment button.
class CapturaDialogAct extends DialogFragment {

    ...
    
    // Step 1
    public interface OnSelectionListener {
        void onConfirmed(String codigo, String precio, String preciounidadextra, String cantidadminima
                    , String primadominical, String tipojornada);
    }

    private OnSelectionListener mOnSelectionListener;

    // Step 2
    
    public CapturaDialogAct(OnSelectionListener listener) {
        this.mOnSelectionListener = listener;
    }



    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
       // View v = inflater.inflate(R.layout.fragment_captura_dialog_act, container, false);
        View v = inflater.inflate(R.layout.frag_capactividades, container, false);      
        //..... reset of code
        
        
        bguardar.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                //Code create recyclerview
                empleado.guardaempleado(codigo.getText().toString(), precio.getText().toString(), preciounidadextra.getText().toString(), cantidadminima.getText().toString()
                        , primadominical.getText().toString(), tipojornada);
                        
                        
                // Step 3
                if (mOnSelectionListener != null) {
                    mOnSelectionListener.onConfirmed(codigo.getText().toString(), precio.getText().toString(), preciounidadextra.getText().toString(), cantidadminima.getText().toString()
                        , primadominical.getText().toString(), tipojornada);
                }
                

            }
        });     
    }
   
}

Step 4: at your fragment, change the instantiation of the DialogFragment to implement the interface and handle the returned text with its callback

Replace

DialogFragment dialogs = new CapturaDialogAct(); // creating new object

With

// Step 4
DialogFragment dialogs = new CapturaDialogAct(new CapturaDialogAct.OnSelectionListener() {
    @Override
    public void onConfirmed(String codigo, String precio, String preciounidadextra, String cantidadminima
                , String primadominical, String tipojornada) {
        
        // Do whatever you want with the received text from the DialogFragment

    });

UPDATE

It already performs all the steps, it does not mark an error but it does not create the cardview, I will add the adapter to the post In Step 4 change the list of the RecyclerView adapter, and update the UI.

DialogFragment dialogs = new CapturaDialogAct(new CapturaDialogAct.OnSelectionListener() {
    @Override
    public void onConfirmed(String codigo, String precio, String preciounidadextra, String cantidadminima
                , String primadominical, String tipojornada) {
        
        // Do whatever you want with the received text from the DialogFragment
        listCont = new ArrayList<>();
        listCont.add(new ActividadesModel(codigo, precio, preciounidadextra, cantidadminima, primadominical, tipojornada));
        AdapterAct viewAdapter = new AdapterAct(getContext(), listCont);
        RecyclerView recyclerView = getView().findViewById(R.id.idrecyclerviewCa);
        //recyclerView.setLayoutManager(new GridLayoutManager(getContext(), 1));
        AdapterAct viewAdapter = new AdapterAct(getContext(), listCont);
        recyclerView.setLayoutManager(new LinearLayoutManager(getActivity()));
        recyclerView.setAdapter(viewAdapter);

    });

Edit

You get an error as you define the RecyclerView as a local variable to onCreateView, so you need to select the class RecyclerView field instead. So, the change

public class empleado extends Fragment implements View.OnClickListener {

    RecyclerView idrecyclerview, recyclerView; // this is the field class variable

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View v5 = inflater.inflate(R.layout.activity_empleado, container, false);

        recyclerView = v5.findViewById(R.id.idrecyclerviewCa); // here is the change

Then, added dismiss() when you hit the dialog hide in order to hide it. So, in your dialog fragment add dismiss() as below

    bguardar.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            //Code create recyclerview
            empleado.guardaempleado(codigo.getText().toString(), precio.getText().toString(), preciounidadextra.getText().toString(), cantidadminima.getText().toString()
                    , primadominical.getText().toString(), tipojornada);
            // Step 3
            if (mOnSelectionListener != null) {
                mOnSelectionListener.onConfirmed(codigo.getText().toString(), precio.getText().toString(), preciounidadextra.getText().toString(), cantidadminima.getText().toString()
                        , primadominical.getText().toString(), tipojornada);
            }

            dismiss(); /// <<<<< here is the change
        }
    });

Also made the adapter as a fragment class field in order to use it when you dismiss the dialog so created AdapterAct mViewAdapter in empleado fragment

Here is the your entire fragment after this modificaiton


public class empleado extends Fragment implements View.OnClickListener {

    //private static ArrayList<Object> listCont;
    FloatingActionButton btndialog;
    // public static TextView empleado;
    private SQLiteDatabase db;
    RecyclerView idrecyclerview, recyclerView;
    static List<ActividadesModel> listCont;
    private AdapterAct mViewAdapter;


    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View v5 = inflater.inflate(R.layout.activity_empleado, container, false);

        recyclerView = v5.findViewById(R.id.idrecyclerviewCa);
        recyclerView.setLayoutManager(new GridLayoutManager(getContext(), 1));

        listCont = new ArrayList<>();
        mViewAdapter = new AdapterAct(getContext(), listCont);
        recyclerView.setLayoutManager(new LinearLayoutManager(getActivity()));
        recyclerView.setAdapter(mViewAdapter);
        return v5;
    }

    //public empleado(String codigo,String precio,String preciounidadextra,String cantidadminima,String primadominical,String tipojornada){
    public empleado() {
        //  listCont = new ArrayList<>();
        // listCont.add(new ActividadesModel("precio", "preciounidadextra", "cantidadminima", "primadominical", "codigo", "tipojornada"));
    }

    public static void guardaempleado(String codigo, String precio, String preciounidadextra, String cantidadminima, String primadominical, String tipojornada) {
        listCont = new ArrayList<>();
        listCont.add(new ActividadesModel(precio, preciounidadextra, cantidadminima, primadominical, codigo, tipojornada));
        //  new empleado();
    }

        super.onCreate(savedInstanceState);

            //do your function here
            Toast.makeText(getActivity(), "Sincronizar", Toast.LENGTH_SHORT).show();
        }

And for your adapter, added a new method called addItem that accepts a new row in the adapter and notifiy change in last item.


public class AdapterAct extends RecyclerView.Adapter<AdapterAct.MyViewHolder> implements Filterable {

    private List<ActividadesModel> actividadesModelList;
    private Context context;
    private List<ActividadesModel> actividadesArrayList;
    private IAxiliarActividades iAxiliarActividades;
    List<ActividadesModel> contactList;
    // Este es nuestro constructor (puede variar según lo que queremos mostrar)
    private String[] mDataSet;
    private List<ActividadesModel> listCont;

    public AdapterAct(Context context, List<ActividadesModel> listCont) {
        this.context = context;
        this.contactList = listCont;
        this.listCont = listCont;
    }


    public AdapterAct(String[] myDataSet) {
        mDataSet = myDataSet;
    }

    @NonNull
    @Override
    public MyViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        // return null;
        View v;
        v = LayoutInflater.from(context).inflate(R.layout.card_actividad, parent, false);
        return new MyViewHolder(v);
    }

    public void addItem(ActividadesModel item) {
        this.listCont.add(item);
        notifyItemChanged(listCont.size() - 1);
    }

    public static class MyViewHolder extends RecyclerView.ViewHolder {
        TextView name;
        TextView precio;

        public MyViewHolder(View itemView) {
            super(itemView);
            this.name = (TextView) itemView.findViewById(R.id.txtNombreMostrar);
            this.precio = (TextView) itemView.findViewById(R.id.txtPrecioMostrar);
        }
    }

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

        ActividadesModel actividadesModel = listCont.get(position);
        //Codigo para crear el listado de acitividades
//        holder.name.setText("nameprueba");
        holder.precio.setText(actividadesModel.getCodigo());
        holder.precio.setText(actividadesModel.getPrecio());
//        holder.precio.setText("precio23");

    }

    @Override
    public int getItemCount() {
        return listCont == null ? 0 : listCont.size();
    }

    @Override
    public Filter getFilter() {
        return null;
    }


}
