// 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);
}
}
}
推荐答案
请按照以下步骤创建DialogFragment输入的接口侦听器，以将其返回到片段.
Please follow below steps to create interface listener for the the DialogFragment input to be returned to your fragment.
- 步骤1:在
CapturaDialogAct内部创建一个界面DialogFragment及其实例字段: - 步骤2:修改
CapturaDialogAct以接受此参数 界面 - 第3步:每当您单击
DialogFragment按钮.
- Step 1: Create an interface inside the
CapturaDialogActDialogFragment, and an instance field of it: - Step 2: Modify the
CapturaDialogActto accept an argument of this interface - Step 3: Trigger the interface method whenever you click the
DialogFragmentbutton.
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);
}
}
});
}
}
步骤4:，在您的代码段中，更改DialogFragment的实例化以实现接口并使用其回调处理返回的文本
Step 4: at your fragment, change the instantiation of the DialogFragment to implement the interface and handle the returned text with its callback
替换
DialogFragment dialogs = new CapturaDialogAct(); // creating new object
使用
// 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
});
更新
它已经执行了所有步骤，没有标记错误，但是没有创建cardview，我将适配器添加到帖子中 在步骤4中，更改RecyclerView适配器的列表，然后更新UI.
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);
});
修改
在将RecyclerView定义为onCreateView的局部变量时会出现错误，因此您需要选择类RecyclerView字段.
所以，改变
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
然后，在您单击对话框隐藏时添加了dismiss()以将其隐藏.
因此，在对话框片段中，按如下所示添加dismiss()
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
}
});
还将适配器设置为片段类字段，以便在关闭在empleado片段中创建的AdapterAct mViewAdapter对话框时使用它
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
这是修改后的整个片段
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();
}

为您的适配器添加了一个名为addItem的新方法，该方法接受适配器中的新行并通知最后一项更改.
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;
}
}
