I want to pass Date and Time I got using Datepicker Dialog and Timepicker Dialog to next Activity in Android studio

Question

This is the Java code that Datepicker and Timepicker work. Those two are working properly so I want to send that selected date and time to the next activity( Doctor_Time_Picking_data_page.java )

 Doctor_Time_Picking_page.java
     public class Doctor_Time_Picking_page extends AppCompatActivity {
        public static final String TEXT_TO_SEND ="com.example.dogapp.TEXT_TO_SEND";
        private DatePickerDialog datePickerDialog;
        private Button dateButton;
        private Button timeButton;
        private Bundle savedInstanceState;
        private Button saveButton;
        private String DATE;
    
    
        //On Create method-------------------------------------------------------------------------------------------------------------------------
        @Override
        protected void onCreate(Bundle savedInstanceState)
        {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_doctor_time_picking_page);
            initDatePicker();
            dateButton = findViewById(R.id.datePickerButton);
            timeButton = findViewById(R.id.timeButton);
            saveButton =  findViewById(R.id.date_time_save_button);
    
     
            Intent intent = new Intent(getApplicationContext(),Doctor_Time_Picking_data_page.class);
     
            saveButton.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {
                    startActivity(intent);
                }
            });
    
    

        }
    
    //-----------------------------------------------------------------------------------------------------------------------------------

            Calendar cal = Calendar.getInstance();

This is the page where I want to show the date and Time selected form my previous activity(Doctor_Time_Picking_page.java)

Doctor_Time_Picking_data_page.java : public class Doctor_Time_Picking_data_page extends AppCompatActivity {

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

            Button Button1a = findViewById(R.id.doc_page4_btn1);
            Button Button2a = findViewById(R.id.doc_page4_btn2);
            Button Button3a = findViewById(R.id.doc_page4_btn3);
            Dialog nDialog = new Dialog(this);
    
            
            Button1a.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {
                    Intent intent = new Intent(Doctor_Time_Picking_data_page.this,Doctor_Appoinment_payment.class);
                    startActivity(intent);
                }
            });
    
            Button2a.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {
                    Intent intent = new Intent(Doctor_Time_Picking_data_page.this,Doctor_Time_Picking_page.class);
                    startActivity(intent);
                }
            });
    
            Button3a.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {
                    nDialog.setContentView(R.layout.activity_doctor_delete_popup_msg);
                    nDialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
                    Intent intent = new Intent(Doctor_Time_Picking_data_page.this,Doctor_delete_popup_msg.class);
                    startActivity(intent);
                }
            });
    
        }
    }

In my project there are three buttons those are Select Time, Select Date and save button when I select each button Datepicker and Timepicker dialogues appear when I select Date or time those Data is appearing on the Buttons I want to pass those data to my next activity which is Doctor_Time_Picking_data_page.java and display them to user. What I now want is I want to pass That data selected from those Pickers to next activity

You need to pass an intent extra to the other activity to get your result. Follow the steps:

1. Create a filed name date in your class:

private String date = "JAN 1 2022"; // I have given a sample date

2. You need to store the date inside the DateSetListener like this:

 DatePickerDialog.OnDateSetListener dateSetListener = new DatePickerDialog.OnDateSetListener()
            {
                @Override
                public void onDateSet(DatePicker datePicker, int year, int month, int day)
                {
                    month = month + 1;
                    date = makeDateString(day, month, year);
                    dateButton.setText(date);
    
    
    
                }
            };

2. You need to pass that date on the click of the save button:

saveButton.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {
                    intent.putExtra("date", date);
                    startActivity(intent);
                }
            });

3. Then you need to get that date on the other activity like this:

public class Doctor_Time_Picking_data_page extends AppCompatActivity {

        ...
 
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_doctor_time_picking_data_page);
    
               String date = getIntent().getStringExtra("date", "");
    
               // 👆 that is the date from the previous activity
          
               ...
            });
            
            ...

    }
