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

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);
}
});
}
//-----------------------------------------------------------------------------------------------------------------------------------
private Bundle initDatePicker()
{
DatePickerDialog.OnDateSetListener dateSetListener = new DatePickerDialog.OnDateSetListener()
{
#Override
public void onDateSet(DatePicker datePicker, int year, int month, int day)
{
month = month + 1;
String date = makeDateString(day, month, year);
dateButton.setText(date);
}
};
Calendar cal = Calendar.getInstance();
int year = cal.get(Calendar.YEAR);
int month = cal.get(Calendar.MONTH);
int day = cal.get(Calendar.DAY_OF_MONTH);
int style = AlertDialog.THEME_HOLO_LIGHT;
datePickerDialog = new DatePickerDialog(this, style, dateSetListener, year, month, day);
datePickerDialog.getDatePicker().setMinDate(System.currentTimeMillis() - 1000);
return null;
}
private String makeDateString(int day, int month, int year)
{
return getMonthFormat(month) + " " + day + " " + year;
}
private String getMonthFormat(int month)
{
if(month == 1)
return "JAN";
if(month == 2)
return "FEB";
if(month == 3)
return "MAR";
if(month == 4)
return "APR";
if(month == 5)
return "MAY";
if(month == 6)
return "JUN";
if(month == 7)
return "JUL";
if(month == 8)
return "AUG";
if(month == 9)
return "SEP";
if(month == 10)
return "OCT";
if(month == 11)
return "NOV";
if(month == 12)
return "DEC";
//default should never happen
return "JAN";
}
public void openDatePicker(View view)
{
datePickerDialog.setTitle("Select Date");
datePickerDialog.show();
}
//Time Button
int hour, minute;
public void popTimePicker(View view)
{
TimePickerDialog.OnTimeSetListener onTimeSetListener = new TimePickerDialog.OnTimeSetListener()
{
#Override
public void onTimeSet(TimePicker timePicker, int selectedHour, int selectedMinute)
{
hour = selectedHour;
minute = selectedMinute;
timeButton.setText(String.format(Locale.getDefault(), "%02d:%02d",hour, minute));
}
};
TimePickerDialog timePickerDialog = new TimePickerDialog(this, /*style,*/ onTimeSetListener, hour, minute, true);
timePickerDialog.setTitle("Select Time");
timePickerDialog.show();
}
}
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:
Create a filed name date in your class:
private String date = "JAN 1 2022"; // I have given a sample date
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);
}
};
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);
}
});
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
...
});
...
}

java.lang.ClassCastException: Search cannot be cast to android.app.Activity

Hi does anyone know why i am getting this error in runtime? I am unsure how to resolve it and i am new to this. Please help! I have called the Search class in my MainActivity and my app crashes when i click on the button to open it.

Your Search class is a Fragment, you cannot start it with the Intent.
Make Search to be Activity or switch between fragments using FragmentManager.

Intent intent = new Intent(MainActivity.this, Search.class);
The Intent constructor doesn't expect a Fragment class as a second Argument, Here you add Search.class which is a Fragment, but you need to have an Activity instead
Fragments can be loaded in activities using a Transaction, not an intent.

Using this code, i am displaying Monday to Sunday like
2017-7-3 to 2017-7-9 ,2017-7-10 to 2017-7-16 ,2017-7-17 to 2017-7-23
,2017-7-24 to 2017-7-30 ,2017-7-31 to 2017-8-5 ...
Receptively but what I want, if current week is
2017-7-24 to 2017-7-30
then when we click on next week it should display it should display only previous week please suggest me in this scenario I will compare date.

if (c.getTime().after(new Date())){
next.setVisibility(View.GONE);
}else {
next.setVisibility(View.VISIBLE);
}
apply this Condition and enjoy !!

Get 12 hour time from DateTime picker

I am using Material DateTime picker for choosing date and time. Its working fine, but in onTimeSetListener method it returns hourOfTheDay in 24 hours format.
I want to show it it 12 hour format for that I used the if condition where hours are greater than 12 then it should show PM, but the hour number dose not change.
How can I change this?

I think your if statement is invalid:

time = (hourOfDay - 12) + ":" + minuteString + " PM";
} else {
...
}

You do not need to reinvent the wheel. In particular, if your app is working with dates and times, you should consider getting the ThreeTenABP library and using the modern Java date and time classes. One of these, LocalTime, solves your task in two lines:
DateTimeFormatter twelveHourTimeFormatter
= DateTimeFormatter.ofPattern("hh:mm:ss a", Locale.ENGLISH);
String time = LocalTime.of(hourOfDay, minute, second)
.format(twelveHourTimeFormatter);
Once you move to Java 8 the classes are built-in and you can discard the library.
In case you don’t want the dependency on one more external library, you can obtain the same with the outdated classes GregorianCalendar, Date and SimpleDateFormat, only it will be less elegant and far from future-proof.

How to restrict user to set date based on other date from date picker in android

Just compare getTimeInMillis of Calendar
Calendar mCalendarFirst = Calendar.getInstance();
mSelectedCalendar.set(Calendar.YEAR, your_year_from_frist_datepicker);
mSelectedCalendar.set(Calendar.MONTH, your_month_from_frist_datepicker);
mSelectedCalendar.set(Calendar.DAY_OF_MONTH, your_day_from_frist_datepicker);
Calendar mCalendarSecond = Calendar.getInstance();
mSelectedCalendar.set(Calendar.YEAR, your_year_from_second_datepicker);
mSelectedCalendar.set(Calendar.MONTH, your_month_from_seconf_datepicker);
mSelectedCalendar.set(Calendar.DAY_OF_MONTH, your_day_from_second_datepicker);
if(mCalendarSecond.getTimeInMillis() <= mCalendarFirst.getTimeInMillis())
{
//Your second date is less than first date
//Show your dialog here.
}
Update:
For your situation use below:
if(Code.DueDate.getTimeInMillis() <= Code.AssignDate.getTimeInMillis())
{
//Your second date is less than first date
//Show your dialog here.
}
Try Below code:
public void onClick(View v) {
switch (v.getId()) {
case R.id.submit:
Code.title = editTextTitle.getText().toString().trim();
Code.description = editTextDesc.getText().toString().trim();
Code.diff = Code.DueDate.getTimeInMillis()
- Code.AssignDate.getTimeInMillis();
Code.days = Code.diff / (24 * 60 * 60 * 1000);
Code.strDays = String.valueOf(Code.days);
Date assignDate = new Date(Code.AssignDate.getTimeInMillis());
Date dueDate = new Date(Code.DueDate.getTimeInMillis());
if (Code.DueDate.getTimeInMillis() <= Code.AssignDate.getTimeInMillis()){
AlertDialog.Builder myDialogBattery = new AlertDialog.Builder(
Assignment_Create.this);
myDialogBattery.setTitle("How to use Less Battery");
myDialogBattery.setMessage("hahahahahaha");
myDialogBattery.setPositiveButton("OK",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface arg0, int arg1) {
}
});
myDialogBattery.show();
}else
{
if (isEdit) {
this.dataManipulator = new DataManipulator(this);
this.dataManipulator.update(updateId);
this.dataManipulator.close();
} else {
this.dataManipulator = new DataManipulator(this);
this.dataManipulator.insert(Code.title, Code.description,
Code.strDays);
this.dataManipulator.close();
}
Toast.makeText(getApplicationContext(),
"Details are saved successfully", Toast.LENGTH_LONG).show();
Toast.makeText(getApplicationContext(),
"Assignment Created Succesfully", Toast.LENGTH_LONG).show();
Assignment_Create.this.finish();
}
break;
}
}

try following code. Here firstDate and secondDate are Date object
if (firstDate.after(secondDate)) { OR //secondDate.before(firstDate)
//display alert here
} else {
}
