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()

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);

Datepicker created with DialopFragment showing Calender also

I am new to Android programming and I am using a basic Datepicker created using a DialogFragment. My DatePicker shows up fine on click etc., but the problem is that it is displaying the Calendar view as well. I do not want this. I have been searching for a solution for a day now, and I am unwilling to use custom Datepickers right now, as I want to get familiar with the basics first.
I have also read suggestions such as
yourDatepicker.setCalendarViewShown(false);
or set it to false in the XML. But my DatePicker comes from a DialogFragment, so how do I access this datepicker? How do I set its final view? I do not wish to make changes in the source code as I am still learning the ropes.
My datepicker code:
public class DueDatePickerFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener {
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
final Calendar c = Calendar.getInstance();
int year = c.get(Calendar.YEAR);
int month = c.get(Calendar.MONTH);
int day = c.get(Calendar.DAY_OF_MONTH);
return new DatePickerDialog(getActivity(), this, year, month, day);
}
public void onDateSet(DatePicker view, int year, int month, int day){
// Code to set Due Date TextField to the selected date.
TextView reminderText = (TextView)getActivity().findViewById(R.id.addTaskFormDueDateHolder);
String dueDateStr = year + "-" + month + "-" + day;
reminderText.setText(dueDateStr);
}
}

I have used Datepicker Dialog Fragment, to show the Date picker in dialog.
Here is my Complete Code
MainActivity.java
package com.example.testmydrag;
import android.os.Bundle;
import android.view.View;
import android.widget.EditText;
import android.widget.DatePicker;
import android.support.v4.app.FragmentActivity;
import android.app.Dialog;
import android.app.DatePickerDialog;
import android.support.v4.app.DialogFragment;
import java.util.Calendar;
public class MainActivity extends FragmentActivity {
EditText mEdit;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
public void selectDate(View view) {
DialogFragment newFragment = new SelectDateFragment();
newFragment.show(getSupportFragmentManager(), "DatePicker");
}
public void setTheDate(int year, int month, int day) {
mEdit = (EditText)findViewById(R.id.Text);
mEdit.setText(month+"/"+day+"/"+year);
}
/*
* Date Picker Dialog
*/
public class SelectDateFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener {
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
final Calendar c = Calendar.getInstance();
int yy = c.get(Calendar.YEAR);
int mm = c.get(Calendar.MONTH);
int dd = c.get(Calendar.DAY_OF_MONTH);
DatePickerDialog dialog = new DatePickerDialog(getActivity(),this,c.YEAR, c.MONTH, c.DATE);
/*Calendar View if you want to Remove Set it to False*/
dialog.getDatePicker().setCalendarViewShown(true);
/*Spinner View if you want to Show Set it to True*/
dialog.getDatePicker().setSpinnersShown(false);
dialog.setTitle("Pick a date");
return dialog;
}
public void onDateSet(DatePicker view, int yy, int mm, int dd) {
setTheDate(yy, mm+1, dd);
}
}
}
main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<EditText android:text="#+string/date_text"
android:id="#+id/Text"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#+string/pick_date"
android:onClick="selectDate" />
</LinearLayout>

I found a temporary solution, though I am not entirely happy with it. You need minimum SDK version 11 for this.
Basically I added a call to getDatePicker() in my onAcreateDialog function, mentioned in the DueDatePickerFragment, and then changed its settings. I don't understand why I need to do this, and why it is appearing so incorrectly in my emulator. No one else seems to be having this problem. Any explanations would be highly appreciated. Here is the code:
#Override
public Dialog onCreateDialog(Bundle savedInstanceState){
Log.i("DUEDATEPICKERDIALOG", "Inside onCreateDIALOG");
final Calendar c = Calendar.getInstance();
int year = c.get(Calendar.YEAR);
int month = c.get(Calendar.MONTH);
int day = c.get(Calendar.DAY_OF_MONTH);
DatePickerDialog datePickerDialogObj = new DatePickerDialog(getActivity(), this, year, month, day);
DatePicker dueDatePicker = datePickerDialogObj.getDatePicker();
float scaleVal = (float) 0.6;
dueDatePicker.setScaleX(scaleVal);
dueDatePicker.setScaleY(scaleVal);
dueDatePicker.setCalendarViewShown(false);
return datePickerDialogObj;
}
Hope this helps someone.

DatePicker Example in android

Please suggest me some tutorial which gives the example for DatePicker and how to use its methods like OnDateChangedListener, onDateChanged etc. Actually I am going through some sites, but i did not get the clear idea of it.
Thank you

Android references on DatePicker is quite good. Have a look at it here.
private DatePicker datePicker;
//monthofYear is between 0-11
datePicker.init(2010, 11, 1, new OnDateChangedListener() {
#Override
public void onDateChanged(DatePicker view, int year, int monthOfYear,int dayOfMonth) {
// Notify the user.
}
});

See.Example(); here

Check this Data Picker example: Example of DATE PICKER .

Step 1 : create a java file:
package com.example.babs;
import java.util.Calendar;
import android.app.Activity;
import android.app.DatePickerDialog;
import android.app.Dialog;
import android.app.DialogFragment;
import android.os.Bundle;
import android.view.View;
import android.widget.DatePicker;
import android.app.FragmentManager;
public class EditUserInfo extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.user_edit_view);
}
public class DatePickerFragment extends DialogFragment
implements DatePickerDialog.OnDateSetListener {
// pgrm mark ---- ---- ----- ---- ---- ----- ---- ---- ----- ---- ---- -----
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
// Use the current date as the default date in the picker
final Calendar c = Calendar.getInstance();
int year = c.get(Calendar.YEAR);
int month = c.get(Calendar.MONTH);
int day = c.get(Calendar.DAY_OF_MONTH);
// Create a new instance of DatePickerDialog and return it
return new DatePickerDialog(getActivity(), this, year, month, day);
}
public void onDateSet(DatePicker view, int year, int month, int day) {
// Do something with the date chosen by the user
}
}
public void showDatePickerDialog(View v) {
FragmentManager fragmentManager = getFragmentManager();
DialogFragment newFragment = new DatePickerFragment();
newFragment.show(fragmentManager, "datePicker");
}
}// end main class EditUserInfo
step 2: your xml file must contain :
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#android:color/white"
android:fillViewport="true" >
</ScrollView>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/pick_date"
android:onClick="showDatePickerDialog" />

You can try this code:
public
static class DatePickerFragment extends DialogFragment implements
DatePickerDialog.OnDateSetListener {
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
// Use the current date as the default date in the picker
final Calendar c = Calendar.getInstance();
int year = c.get(Calendar.YEAR);
int month = c.get(Calendar.MONTH);
int day = c.get(Calendar.DAY_OF_MONTH);
// Create a new instance of DatePickerDialog and return it
return new DatePickerDialog(getActivity(), this, year, month, day);
}
public void onDateSet(DatePicker view, int year, int month, int day) {
// Do something with the date chosen by the user
DateEdit.setText(day + "/" + (month + 1) + "/" + year);
}
}
Taken from Example of DatePickerFragment and TimePickerFragment.
