Timepicker and DatePicker Dialog in Android

We can use Time Picker  and Date Picker   widget to select a time and date , but TimePickerDialog and DatePickerDialog  is a better choice to do that.

In this post I will discuss how to use DatePickerDialog and TimePickerDialog to select Date and Time.



DatePickerDialog In Android
                      





Here I have described briefly, the Example with full source code is given below after this.
 
Declare following Variables in your Activity/Class

static final int DATE_DIALOG_ID = 0;
static final int TIME_DIALOG_ID=1;

public  int year,month,day,hour,minute;  // declare  the variables to show the date and time whenTime and                                                          //Date Picker Dialog first appears

private int mYear, mMonth, mDay,mHour,mMinute; // variables to save user selected date and time

In the constructor you can initiallise the variable to current date and time.

                   year=month=day=hour=minute=1;
                    final Calendar c = Calendar.getInstance();
                    mYear = c.get(Calendar.YEAR);
                    mMonth = c.get(Calendar.MONTH);
                    mDay = c.get(Calendar.DAY_OF_MONTH);
                    mHour = c.get(Calendar.HOUR_OF_DAY);
                    mMinute = c.get(Calendar.MINUTE);



//call the method when you need to show DatePickerDialog
 showDialog(DATE_DIALOG_ID);
//call the method when you need to show DatePickerDialog
  showDialog(TIME_DIALOG_ID);

// Register  DatePickerDialog listener
 private DatePickerDialog.OnDateSetListener mDateSetListener =
                        new DatePickerDialog.OnDateSetListener() {
                 // the callback received when the user "sets" the Date in the DatePickerDialog
                            public void onDateSet(DatePicker view, int yearSelected,
                                                  int monthOfYear, int dayOfMonth) {
                               year = yearSelected;
                               month = monthOfYear;
                               day = dayOfMonth;
                              Toast.makeText(getApplicationContext(), "Date selected is:"+day+"-"+month+"-"+year, Toast.LENGTH_LONG).show();
                                                         }
                        };


   // Register  TimePickerDialog listener                 
                        private TimePickerDialog.OnTimeSetListener mTimeSetListener =
                            new TimePickerDialog.OnTimeSetListener() {
             // the callback received when the user "sets" the TimePickerDialog in the dialog
                                public void onTimeSet(TimePicker view, int hourOfDay, int min) {

                                    hour = hourOfDay;
                                    minute = min;
                                   Toast.makeText(getApplicationContext(), "Time selected is:"+hour+"-"+minute, Toast.LENGTH_LONG).show();
                                                                  }
                            };


// Method automatically gets Called when you call showDialog()  method
                        @Override
                        protected Dialog onCreateDialog(int id) {
                            switch (id) {
                            case DATE_DIALOG_ID:
                                return new DatePickerDialog(this,
                                            mDateSetListener,
                                            mYear, mMonth, mDay);
                            case TIME_DIALOG_ID:
                                return new TimePickerDialog(this,
                                        mTimeSetListener, mHour, mMinute, false);
                           
                            }
                            return null;
                        }
                        

Date And Time Picker Dialog Example with Full Source Code

In the example   I have 2 buttons  
1: Select Date - to show DatePickerDialog 
2: Select Time - to show TimePickertDialog
When user selects a Date and Time in respective Dialogs we will set the selected date and time in Respective buttons. We will set selected date in Select Date Button and selected time in Select Time Button(See the last Snapshot)
