Example of Android DatePicker Widget

At first, we will create android application. Then, we will use datePicker widget in this application.

1. Creating New Project

Follow steps below to create new project. Please ignore the steps if you have already created a new application.

Now, we will modify xml and java file to use datePicker widget in the application.

2. Modify Values folder

No values folder have been modified. So, we are not going to mention them here.

3. Use DatePicker Widget in xml file

Open res/layout/activity_main.xml file. Then, add below code into it.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
	xmlns:android="http://schemas.android.com/apk/res/android"
	android:layout_width="match_parent"
	android:layout_height="match_parent"
	android:layout_margin="10dp"
	android:gravity="center"
	android:orientation="vertical">

	<DatePicker
		android:id="@+id/datePicker"
		android:layout_width="wrap_content"
		android:layout_height="wrap_content"/>

	<TextView
		android:id="@+id/textView"
		android:layout_width="match_parent"
		android:layout_height="wrap_content"
		android:layout_marginTop="3dp"/>

</LinearLayout>

In activity_main.xml file, we have defined textView and datePicker in android application. Now, we will access these widgets in java file.

4. Access DatePicker Widget in java file

Open src/main/java/com.tutorialwing.datepicker/MainActivity.java file. Then, add below code into it.

package com.tutorialwing.datepicker;

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.widget.DatePicker;
import android.widget.TextView;
import android.widget.Toast;

import java.util.Calendar;

public class MainActivity extends AppCompatActivity {

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

		final TextView textView = findViewById(R.id.textView);

		DatePicker datePicker = findViewById(R.id.datePicker);
		if (datePicker != null) {
			Calendar today = Calendar.getInstance();
			datePicker.init(today.get(Calendar.YEAR), today.get(Calendar.MONTH), today.get(Calendar.DAY_OF_MONTH),

					new DatePicker.OnDateChangedListener() {

						@Override
						public void onDateChanged(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
							String msg = "Selected Date is " + dayOfMonth + "/" + monthOfYear + "/" + year;
							Toast.makeText(MainActivity.this, msg, Toast.LENGTH_SHORT).show();

							if (textView != null) {
								textView.setText(msg);
							}
						}
					});
		}
	}
}

In MainActivity.java file, we have accessed textView and datePicker widgets. Then, we have set date change listener to display selected date in textView widget.

Since AndroidManifest.xml file is very important in any android application, we are also going to see the content inside this file.

AndroidManifest.xml

Code inside src/main/AndroidManifest.xml file is as below –

<?xml version="1.0" encoding="utf-8"?>
<manifest package="com.tutorialwing.datepicker"
		  xmlns:android="http://schemas.android.com/apk/res/android">

	<application
		android:allowBackup="true"
		android:icon="@mipmap/ic_launcher"
		android:label="@string/app_name"
		android:roundIcon="@mipmap/ic_launcher_round"
		android:supportsRtl="true"
		android:theme="@style/AppTheme">
		<activity android:name=".MainActivity">
			<intent-filter>
				<action android:name="android.intent.action.MAIN"/>

				<category android:name="android.intent.category.LAUNCHER"/>
			</intent-filter>
		</activity>
	</application>

</manifest>

When we run the program, we will get output as shown above.

That’s end of tutorial on Android DatePicker widget.
