Date picker in Android

Question

Can any one post sample code for a simple date picker in Android.

If date picker is not possible in Android, an option to choose a date is needed.

Answer 1

To use DatePicker add below source code in your OnCreate of Activity.

PS: make sure that android:focusable="false" should be provided for your EditText.

// Edittext in your layout file
date = (EditText) findViewById(R.id.date);
// onclick on edit text
date.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
    final Calendar c = Calendar.getInstance();
    int mYear = c.get(Calendar.YEAR); // current year
    int mMonth = c.get(Calendar.MONTH); // current month
    int mDay = c.get(Calendar.DAY_OF_MONTH); // current day
    // date picker dialog
    datePickerDialog = new DatePickerDialog(MainActivity.this,
         new DatePickerDialog.OnDateSetListener() {

                 @Override
                 public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
                     // set day of month , month and year value in the edit text
                     date.setText(dayOfMonth + "/"+ (monthOfYear + 1) + "/" + year);
                 }
         }, mYear, mMonth, mDay);
                datePickerDialog.show();
    }
});

When you click on the Edittext it will open the Calendar.

Answer 2

use: import java.util.Calendar;

instead: import android.icu.util.Calendar.

this package supports only for API level-24 not less than that. This is the package we need to use to get Calendar on the dialog box,

this works fine.

Answer 3

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" />

Answer 4

The accepted answer doesn't handle the user clicking cancel in the date picker. In that case, nothing should be updated.

I wanted the same thing as OP, but I just wanted it in-line. Here's what I used:

Create the callback that will be called when the date picker OK button is clicked:

public void datePicked(int year, int month, int day) {
    buttonDate.setText(String.valueOf(year) + "/" + 
          String.valueOf(month) + "/" + String.valueOf(day));
}

Then use the following code in the method where you create a button to pick the date:

    buttonDate = (Button) rootView.findViewById(R.id.button_select_date);
    buttonDate.setText("Select Date");
    buttonDate.setOnClickListener(new View.OnClickListener() {
        public void setReturnDate(int year, int month, int day) {
            datePicked(year, month, day);
        }

        @Override
        public void onClick(View v) {
            Dialog datePickerDialog = new DatePickerDialog(activity, new DatePickerDialog.OnDateSetListener() {
                @Override
                public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {

                }
            }, leagueEndDate.get(Calendar.YEAR), leagueEndDate.get(Calendar.MONTH), leagueEndDate
                    .get(Calendar.DAY_OF_MONTH));
            datePickerDialog.setOnDismissListener(new DialogInterface.OnDismissListener() {
                @Override
                public void onDismiss(DialogInterface dialog) {
                    setReturnDate(((DatePickerDialog) dialog).getDatePicker().getYear(),
                            ((DatePickerDialog) dialog).getDatePicker().getMonth(), ((DatePickerDialog) dialog)
                                    .getDatePicker().getDayOfMonth());
                }
            });
            datePickerDialog.show();
        }
    });

Answer 8

Use the DatePicker

http://developer.android.com/reference/android/widget/DatePicker.html

It is availible since API Level 1

Here a example how to use the DatePickerDialog.

First add a TextView and a Button to your layout.xml

<Button android:id="@+id/myDatePickerButton"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Choose Date"/>

<TextView android:id="@+id/showMyDate"
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content"/>

Next you have to initialize the Button and TextView in the onCreate Method of your layout. You need this class variables

private int mYear;
private int mMonth;
private int mDay;

private TextView mDateDisplay;
private Button mPickDate;

static final int DATE_DIALOG_ID = 0;

Here the onCreate method

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    mDateDisplay = (TextView) findViewById(R.id.showMyDate);        
    mPickDate = (Button) findViewById(R.id.myDatePickerButton);

    mPickDate.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            showDialog(DATE_DIALOG_ID);
        }
    });

    // get the current date
    final Calendar c = Calendar.getInstance();
    mYear = c.get(Calendar.YEAR);
    mMonth = c.get(Calendar.MONTH);
    mDay = c.get(Calendar.DAY_OF_MONTH);

    // display the current date
    updateDisplay();
}

UpdateDisplay method:

private void updateDisplay() {
    this.mDateDisplay.setText(
        new StringBuilder()
                // Month is 0 based so add 1
                .append(mMonth + 1).append("-")
                .append(mDay).append("-")
                .append(mYear).append(" "));
}

The callback listener for the DatePickDialog

private DatePickerDialog.OnDateSetListener mDateSetListener =
    new DatePickerDialog.OnDateSetListener() {
        public void onDateSet(DatePicker view, int year, 
                              int monthOfYear, int dayOfMonth) {
            mYear = year;
            mMonth = monthOfYear;
            mDay = dayOfMonth;
            updateDisplay();
        }
    };

The onCreateDialog method, called by showDialog()

@Override
protected Dialog onCreateDialog(int id) {
   switch (id) {
   case DATE_DIALOG_ID:
      return new DatePickerDialog(this,
                mDateSetListener,
                mYear, mMonth, mDay);
   }
   return null;
}

Hope it helps, used it and it works fine.
