Date and Time Picker in Android

Date and Time Picker example In Android

In this tutorial we will learn to implement date and time picker with a simple example in Android Studio.

Example:

In this example we have two Button's and two TextView's, button's are to pick date and time and textview's is to show date and time when user hits the button.
Create a new project as DateAndTimePicker in Android Studio.
Design the main layout as follows.

File: activity_main.xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center"
    android:orientation="vertical"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="com.example.hss_24.dateandtimepicker.MainActivity">

    <Button
        android:id="@+id/btn_time"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="pick time" />

    <TextView
        android:id="@+id/txt_time"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginBottom="10dp"
        android:layout_marginTop="10dp"
        android:gravity="center"
        android:textColor="@color/colorAccent"
        android:textStyle="bold" />

    <Button
        android:id="@+id/btn_date"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="pick date" />

    <TextView
        android:id="@+id/txt_date"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginBottom="10dp"
        android:layout_marginTop="10dp"
        android:gravity="center"
        android:textColor="@color/colorAccent"
        android:textStyle="bold" />

</LinearLayout>


Do the following code in java file.
We need Date picker and Time picker dialog's to select the date and time.

File: MainActivity.java:

import android.app.DatePickerDialog;
import android.app.TimePickerDialog;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.Button;
import android.widget.DatePicker;
import android.widget.TextView;
import android.widget.TimePicker;

import java.util.Calendar;

public class MainActivity extends AppCompatActivity {

    Button date, time;
    TextView txt_date, txt_time;
    // variables for storing date and time
    private int mYear, mMonth, mDay, mHour, mMinute;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        date = (Button) findViewById(R.id.btn_date);
        time = (Button) findViewById(R.id.btn_time);

        txt_date = (TextView) findViewById(R.id.txt_date);
        txt_time = (TextView) findViewById(R.id.txt_time);

        date.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if (v == date) {

                    // get Current Date
                    final Calendar c = Calendar.getInstance();
                    mYear = c.get(Calendar.YEAR);
                    mMonth = c.get(Calendar.MONTH);
                    mDay = c.get(Calendar.DAY_OF_MONTH);

                    // Launch Date Picker Dialog
                    DatePickerDialog datePickerDialog = new DatePickerDialog(MainActivity.this,
                            new DatePickerDialog.OnDateSetListener() {

                                @Override
                                public void onDateSet(DatePicker view, int year,
                                                      int monthOfYear, int dayOfMonth) {
                                    // Display Selected date in textbox
                                    txt_date.setText(dayOfMonth + "-"
                                            + (monthOfYear + 1) + "-" + year);

                                }
                            }, mYear, mMonth, mDay);
                    datePickerDialog.show();
                }

            }

        });

        time.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if (v == time) {

                    //  get Current Time
                    final Calendar c = Calendar.getInstance();
                    mHour = c.get(Calendar.HOUR_OF_DAY);
                    mMinute = c.get(Calendar.MINUTE);

                    // Launch Time Picker Dialog
                    TimePickerDialog timePickerDialog = new TimePickerDialog(MainActivity.this,
                            new TimePickerDialog.OnTimeSetListener() {

                                @Override
                                public void onTimeSet(TimePicker view, int hourOfDay,
                                                      int minute) {
                                    // Display Selected time in textbox
                                    txt_time.setText(hourOfDay + ":" + minute);
                                }
                            }, mHour, mMinute, false);
                    timePickerDialog.show();
                }
            }
        });
    }
}
