Show Dialog From Subclass

I want to open a dialog from a subclass.
However, there are some problems with the Show function.
It does not take the subclass but the main class.
The Main Controller :
private void InitNavigation(){
MenuView = findViewById(R.id.bottomNavigationView);
NavHostFragment navHostFragment = (NavHostFragment) getSupportFragmentManager()
.findFragmentById(R.id.fragment);
NavController navCo = navHostFragment.getNavController();
AppBarConfiguration appBarConfiguration = new AppBarConfiguration.Builder(R.id.home2,
R.id.verantstaltung, R.id.veranstalter,R.id.tanzpartnersuche).build();
NavigationUI.setupActionBarWithNavController(this, navCo, appBarConfiguration);
NavigationUI.setupWithNavController(MenuView, navCo);
navCo.navigate(R.id.home2);
}
I think at the Funktion openDatePickerDialog is the error. With getActivity().getsupportFragmentManager i get the Main Class but here i will get the subclass
The Sub Controller from which the dialog should be opened :
private void openDatePickerDialog(String type){
new DialogDatePicker(type).show(getActivity().getSupportFragmentManager(),"DialogDatePicker");
}
}
And Last the Dialog Controller :
package florian.tanzapp;
import android.app.AlertDialog;
import android.app.Dialog;
import android.content.Context;
import android.content.DialogInterface;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.CalendarView;
import java.util.Calendar;
import java.util.Date;
import androidx.appcompat.app.AppCompatDialogFragment;
public class DialogDatePicker extends AppCompatDialogFragment {
private DialogDatePickerListener listener;
//DatePicker
CalendarView DatePicker;
//Var
String Type;
Date datum;
public DialogDatePicker(String type){
Type = type;
}
#Override
public Dialog onCreateDialog(Bundle savedInstanceState){
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
LayoutInflater inflater = getActivity().getLayoutInflater();
View view = inflater.inflate(R.layout.dialog_datepicker,null);
builder.setView(view)
.setTitle("DatePicker")
.setNegativeButton("cancel", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
}
})
.setPositiveButton("ok", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
listener.applyDate(datum,Type);
}
});
DatePicker = view.findViewById(R.id.calendarView3);
DatePicker.setMinDate((new Date().getTime()));
DatePicker.setOnDateChangeListener(new CalendarView.OnDateChangeListener() {
#Override
public void onSelectedDayChange(CalendarView view, int year, int month, int dayOfMonth) {
Calendar newDate = Calendar.getInstance();
newDate.set(year, month, dayOfMonth);
datum = newDate.getTime();
}
});
return builder.create();
}
#Override
public void onAttach(Context context){
super.onAttach(context);
try {
listener = (DialogDatePickerListener) context;
}
catch (ClassCastException e){
throw new ClassCastException(context.toString() + "must implement DialogDatePickerListener");
}
}
public interface DialogDatePickerListener{
void applyDate(Date datum, String type);
}
}
I don't have so much experience in Java because I am more specialized in C#. Does anyone see the problem what is wrong when I want to open the dialog from the subclasse ?

Why my recyclerview isn't showing any item?

I just created my recyclerview to show a cardview when I just filling the required data on AddNewTimerFragment.java. But somehow it wont show the card that contains the data that I've fill in before. I've tried to changes something, but doesn't work.

Somebody please help me I am Newbie to this.

This is another method of sending data from Adapter to Activity.
Follow these steps carefully:
Create an interface with a method
public interface InterfaceTax {
public void getTaxMoney(int amount);
}
the parameters of the method should contain the data you want to send back to the activity.
Create a variable for that interface in the Adapter and add the interface to the constructor of the Adapter.
private InterfaceTax interfaceT;
public ChannelAdapter(/* other parameters */, InterfaceTax interface) {
interfaceT = interface;
}
Then in onBindViewHolder (or wherever your data is) call the method of the interface and send the data
#Override
public void onBindViewHolder(#NonNull MyViewHolder holder, int i) {
money = String.valueOf(channel_tMoney.get(i));
interface.getTaxMoney(money);
}
Then in your activity implement the interface and override the method to receive data
public class UserDetailsActivity extends AppCompatActivity implements InterfaceTax {}
#Override
public void getTaxMonney(int data) {
// receive data here
}
In your AddChannel method, replace this line
ChannelAdapter cAdapter = new ChannelAdapter(UserDetailsActivity.this,this,channel_id,channel_name,channel_ntMoney,channel_tMoney);
with this
ChannelAdapter cAdapter = new ChannelAdapter(UserDetailsActivity.this,this,channel_id,channel_name,channel_ntMoney,channel_tMoney, this);
This will automatically send the data from the adapter to the activity and you can receive it in the method overridden in the activity.

Time picker stops working after date picker is added

I'm building an app that displays a date picker and a time picker on the click of two seperate buttons. I first added in the time picker and it was all working fine, I then proceeded to add the date picker which also works fine. The problem here being that when I added in the date picker, it casused the time picker to stop working. I know they both work and i'm 90% sure it is because of the structure of my code but being that i'm completely new to android and java development I can't work out where i'm going wrong. Any help would be appreciated.
