Error:(63, 61) error: incompatible types: MainActivity cannot be converted to Context
Here i paste the complete code.

}
},newCalendar.get(Calendar.YEAR), newCalendar.get(Calendar.MONTH), newCalendar.get(Calendar.DAY_OF_MONTH));
i tried it but it is generating the same error again and again..

you extend fragment so replace this to getActivity()
fromDatePickerDialog = new DatePickerDialog(getActivity(), new DatePickerDialog.OnDateSetListener() {}

The constructor of DatePickerDialog expects a Context param.
You're passing your Fragment instance to the constructor of DatePickerDialog, but Fragment is not a Context subclass.
Either pass getContext() or getActivity() instead of this.
Change the following line:
fromDatePickerDialog = new DatePickerDialog(this,
new DatePickerDialog.OnDateSetListener() {
To this:
fromDatePickerDialog = new DatePickerDialog(getContext(),
new DatePickerDialog.OnDateSetListener() {
Or to this:
fromDatePickerDialog = new DatePickerDialog(getActivity(),
new DatePickerDialog.OnDateSetListener() {
According to your code you have multiple DatePickerDialogs, so you need to perform this change on all of them.
P.S. Your Fragment should not be called MainActivity.

How to get date "value" from DatePicker?

I don't know how to get the date value from Datepicker.
PickerDialog.java
package com.example.alecksjohanssen.newyorktimes;
/**
* Created by AlecksJohanssen on 3/19/2016.
*/
import android.app.DatePickerDialog;
import android.app.Dialog;
import android.app.DialogFragment;
import android.os.Bundle;
import java.util.Calendar;
public class PickerDialog extends DialogFragment {
#Override
public Dialog onCreateDialog(Bundle savedInstanceState)
{ DateSettings dateSettings = new DateSettings(getActivity());
Calendar calendar = Calendar.getInstance();
int year = calendar.get(Calendar.YEAR);
int month = calendar.get(Calendar.MONTH);
int dayofmonth = calendar.get(Calendar.DAY_OF_MONTH);
DatePickerDialog dialog;
dialog = new DatePickerDialog(getActivity(),dateSettings,year,month,dayofmonth);
return dialog;
}
}
DateSetting.java
package com.example.alecksjohanssen.newyorktimes;
import android.app.DatePickerDialog;
import android.content.Context;
import android.widget.DatePicker;
import android.widget.Toast;
/**
* Created by My name Is Hardline on 2/26/2016.
*/
public class DateSettings implements DatePickerDialog.OnDateSetListener {
Context context;
public DateSettings(Context context) {
this.context = context;
}
#Override
public void onDateSet(DatePicker view, int year, int monthofyear,int dayofmonth) {
Toast.makeText(context, "Selected date" + monthofyear + "/" + dayofmonth + "/" + year, Toast.LENGTH_LONG).show();
}
}
public void setDate() {
PickerDialog pickerDialogs = new PickerDialog();
pickerDialogs.show(getFragmentManager(), "date_picker");
}
It's basically it, it's only shows that Selected date is . Still I'm looking for how to extract the date data so that I can put it on my Begin Date :P.

You can try like this
private void datePicker(){
Calendar calendar = Calendar.getInstance();
final SimpleDateFormat dateFormatter = new SimpleDateFormat("yyyy-MM-dd", Locale.US);
DatePickerDialog datePickerDialog = new DatePickerDialog(activity, new DatePickerDialog.OnDateSetListener() {
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
Calendar newDate = Calendar.getInstance();
newDate.set(year, monthOfYear, dayOfMonth);
System.out.print(dateFormatter.format(newDate.getTime()));
}
}, calendar.get(Calendar.YEAR), calendar.get(Calendar.MONTH), calendar.get(Calendar.DAY_OF_MONTH));
datePickerDialog.show();
}

Say you have Calendar mCalendar that you want to init the date picker with it.
dialog.getDatePicker().init(mCalendar.get(Calendar.YEAR), mCalendar.get(Calendar.MONTH), mCalendar.get(Calendar.DAY_OF_MONTH), new DatePicker.OnDateChangedListener() {
#Override
public void onDateChanged(DatePicker datePicker, int i, int i2, int i3) {
mCalendar.set(i, i2, i3);
}
});
Then to get the picked date
mCalendar.getTime()

DatePicker returns null (Android)

I'm trying to show DatePicker when user clicks the calendar icon in ActionBar and set the date picked in Textview.But I keep on getting these error.Any help or suggestions would be appreciated.Thank you.
sendUserActionEvent()mView==null
This is my code:
private DatePickerDialog PickDateDialog;
//I called setDataField() in onCreate
private void setDateField() {
Calendar newCalendar = Calendar.getInstance();
PickDateDialog = new PickDateDialog(this, new OnDateSetListener()
{
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
Calendar newDate = Calendar.getInstance();
newDate.set(year, monthOfYear, dayOfMonth);
add_show.setText(dateFormatter.format(newDate.getTime()));
}
},newCalendar.get(Calendar.YEAR), newCalendar.get(Calendar.MONTH), newCalendar.get(Calendar.DAY_OF_MONTH));
}
//Under onOptionsItemSelected menu
if (id == R.id.action_pickdate) {
PickDateDialog.show();
return true;
};

I tried your code, and it works!
Just using his DateFormat

setDateField();
}
private void setDateField() {

PickDateDialog = new DatePickerDialog(this, new DatePickerDialog.OnDateSetListener() {
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
Calendar newDate = Calendar.getInstance();
newDate.set(year, monthOfYear, dayOfMonth);
add_show.setText(newDate.getTime().toLocaleString());
}
},newCalendar.get(Calendar.YEAR), newCalendar.get(Calendar.MONTH), newCalendar.get(Calendar.DAY_OF_MONTH));
}
#Override

How to disable future date with Datepicker

I am trying to disable date picker for future date but getting not idea...
Here is the what I have tried:
bday.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Calendar mcurrentDate=Calendar.getInstance();
year=mcurrentDate.get(Calendar.YEAR);
month=mcurrentDate.get(Calendar.MONTH);
day=mcurrentDate.get(Calendar.DAY_OF_MONTH);
DatePickerDialog mDatePicker =new DatePickerDialog(CreateAccountActivity.this, new OnDateSetListener()
{
#Override
public void onDateSet(DatePicker datepicker, int selectedyear, int selectedmonth, int selectedday)
{
year = selectedyear;
month = selectedmonth;
day = selectedday;
DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");
Calendar cal = Calendar.getInstance();
String currenttime = new String(dateFormat.format(cal.getTime()));
String selectedtime = new String (new StringBuilder().append(year).append("-").append(month+1).append("-").append(day));
String futuretime = new String (dateFormat.format(System.currentTimeMillis()));
if(selectedtime==currenttime)
{
Toast.makeText(getApplicationContext(), "you were not born in the future", Toast.LENGTH_SHORT).show();
bday.setText("");
}
else
{
bday.setText(new StringBuilder().append(year).append("-").append(month+1).append("-").append(day));
}}
},year, month, day);
mDatePicker.setTitle("Please select date");
mDatePicker.show();
}
});
Stackoverflow suggested to use:
mDatePicker.getDatePicker().setMaxDate(System.currentTimeMillis());
but in above condition how should I use this.?
I am trying to disable future date. But not getting any idea :(

After Declaring Listener on DatePicker use the mDatePicker.getDatePicker().setMaxDate(System.currentTimeMillis());

package com.keshav.datePicker_With_Hide_Future_Past_Date;
import android.app.DatePickerDialog;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.DatePicker;
import android.widget.EditText;
import java.util.Calendar;
public class MainActivity extends AppCompatActivity {
EditText ed_date;
int year;
int month;
int day;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ed_date=(EditText) findViewById(R.id.et_date);
ed_date.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v)
{
Calendar mcurrentDate=Calendar.getInstance();
year=mcurrentDate.get(Calendar.YEAR);
month=mcurrentDate.get(Calendar.MONTH);
day=mcurrentDate.get(Calendar.DAY_OF_MONTH);
final DatePickerDialog mDatePicker =new DatePickerDialog(MainActivity.this, new DatePickerDialog.OnDateSetListener()
{
#Override
public void onDateSet(DatePicker datepicker, int selectedyear, int selectedmonth, int selectedday)
{
ed_date.setText(new StringBuilder().append(year).append("-").append(month+1).append("-").append(day));
int month_k=selectedmonth+1;
}
},year, month, day);
mDatePicker.setTitle("Please select date");
// TODO Hide Future Date Here
mDatePicker.getDatePicker().setMaxDate(System.currentTimeMillis());
// TODO Hide Past Date Here
// mDatePicker.getDatePicker().setMinDate(System.currentTimeMillis());
mDatePicker.show();
}
});
}
}

How to use DatePicker widget in android?

enter code hereI have used the DatePicker widget in android.Upon clicking that I want the datePickerdialog to show up and date should be set and the same I want to set to a textview.
Thanks in advance.
final Calendar c = Calendar.getInstance();
year = c.get(Calendar.YEAR);
month = c.get(Calendar.MONTH);
day = c.get(Calendar.DAY_OF_MONTH);
DatePickerDialog dpd = new DatePickerDialog(this,new DatePickerDialog.OnDateSetListener() {
#Override
// TODO Auto-generated method stub
public void onDateSet(DatePicker view, int year,int monthOfYear, int dayOfMonth) {
startDateTextView.setVisibility(View.VISIBLE);
startDateTextView.setText(dayOfMonth + "-"+ (monthOfYear + 1) + "-" + year);
}
}, year, month, day);
dpd.show();
the above code i used,bt this works before i click on datepicker. please let me know how to use OnClickListener of datepicker to this

Try below code.
package com.example.datetimepicker;
import android.app.Activity;
import android.app.DatePickerDialog;
import android.app.TimePickerDialog;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.widget.Button;
import android.widget.DatePicker;
import android.widget.TextView;
import android.widget.TimePicker;
import java.text.DateFormat;
import java.util.Calendar;
public class MainActivity extends Activity {
Button date,time;
TextView preview;
int year,monthofyear,dayofmonth,hourofday,minute;
Calendar cal = Calendar.getInstance();
DateFormat dt = DateFormat.getInstance();
TimePickerDialog.OnTimeSetListener tpd;
DatePickerDialog.OnDateSetListener dpd;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
date = (Button)findViewById(R.id.date);
date.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
new DatePickerDialog(MainActivity.this,dpd,
cal.get(Calendar.YEAR),cal.get(Calendar.MONTH),
cal.get(Calendar.DAY_OF_MONTH)).show();
}
});
time = (Button)findViewById(R.id.time);
time.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
new TimePickerDialog(MainActivity.this,tpd,
cal.get(Calendar.HOUR_OF_DAY),cal.get(Calendar.MINUTE),
false).show();
}
});
preview = (TextView)findViewById(R.id.textView1);
dpd = new DatePickerDialog.OnDateSetListener() {
#Override
public void onDateSet(DatePicker view, int year, int monthOfYear,
int dayOfMonth) {
// TODO Auto-generated method stub
cal.set(Calendar.YEAR, year);
cal.set(Calendar.MONTH, monthOfYear);
cal.set(Calendar.DAY_OF_MONTH, dayOfMonth);
preview.setText(new StringBuilder().append(year+"/")
.append(monthOfYear+"/").append(dayOfMonth));
}
};
tpd = new TimePickerDialog.OnTimeSetListener() {
#Override
public void onTimeSet(TimePicker arg0, int hourofday, int minute) {
// TODO Auto-generated method stub
cal.set(Calendar.HOUR_OF_DAY, hourofday);
cal.set(Calendar.MINUTE, minute);
preview.setText(new StringBuilder().append(hourofday+"/")
.append(minute));
}
};
}
}

you can use like this:
//variables
DatePicker dpResult;
static final int DATE_DIALOG_ID = 999;
//methods
public void setCurrentDateOnView() {
dpResult = (DatePicker) findViewById(R.id.dpResult);
dpResult.setVisibility(View.GONE );
final Calendar c = Calendar.getInstance();
year = c.get(Calendar.YEAR);
month = c.get(Calendar.MONTH);
day = c.get(Calendar.DAY_OF_MONTH);
// set current date into datepicker
dpResult.init(year-7, month, day, null);
}
#Override
protected Dialog onCreateDialog(int id) {
switch (id) {
case DATE_DIALOG_ID:
// set date picker as current date
return new DatePickerDialog(this, datePickerListener, year, month,
day);
}
return null;
}
private DatePickerDialog.OnDateSetListener datePickerListener = new DatePickerDialog.OnDateSetListener() {
// when dialog box is closed, below method will be called.
public void onDateSet(DatePicker view, int selectedYear,
int selectedMonth, int selectedDay) {
year = selectedYear;
month = selectedMonth;
day = selectedDay;
// set selected date into textview
mbirthdayView.setText( (day)+(".")+(month + 1)+(".")+(year));
// set selected date into datepicker also
dpResult.init(year, month, day, null);
}
};
and finally you can call datepicker like this:
showDialog(DATE_DIALOG_ID);
