AndroidApps/ApplicationsMobile Development

This example demonstrates how do I use date and time picker in android.

Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.

Step 2 − Add the following code to res/layout/activity_main.xml.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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"
   tools:context=".MainActivity">
   <Button
      android:id="@+id/btnPick"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:layout_centerHorizontal="true"
      android:layout_marginTop="30dp"
      android:text="Pick Date and TIme"/>
   <TextView
      android:id="@+id/textView"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:layout_centerInParent="true"
      android:textSize="16sp"
      android:textStyle="bold"/>
</RelativeLayout>

Step 3 − Add the following code to src/MainActivity.java

import android.app.DatePickerDialog;
import android.app.TimePickerDialog;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.text.format.DateFormat;
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 implements DatePickerDialog.OnDateSetListener, TimePickerDialog.OnTimeSetListener {
   TextView textView;
   Button button;
   int day, month, year, hour, minute;
   int myday, myMonth, myYear, myHour, myMinute;
   @Override
   protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
      textView = findViewById(R.id.textView);
      button = findViewById(R.id.btnPick);
      button.setOnClickListener(new View.OnClickListener() {
         @Override
         public void onClick(View v) {
            Calendar calendar = Calendar.getInstance();
            year = calendar.get(Calendar.YEAR);
            month = calendar.get(Calendar.MONTH);
            day = calendar.get(Calendar.DAY_OF_MONTH);
            DatePickerDialog datePickerDialog = new DatePickerDialog(MainActivity.this, MainActivity.this,year, month,day);
            datePickerDialog.show();
         }
      });
   }
   @Override
   public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
      myYear = year;
      myday = day;
      myMonth = month;
      Calendar c = Calendar.getInstance();
      hour = c.get(Calendar.HOUR);
      minute = c.get(Calendar.MINUTE);
      TimePickerDialog timePickerDialog = new TimePickerDialog(MainActivity.this, MainActivity.this, hour, minute, DateFormat.is24HourFormat(this));
      timePickerDialog.show();
   }
   @Override
   public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
      myHour = hourOfDay;
      myMinute = minute;
      textView.setText("Year: " + myYear + "\n" +
         "Month: " + myMonth + "\n" +
         "Day: " + myday + "\n" +
         "Hour: " + myHour + "\n" +
         "Minute: " + myMinute);
   }
}

Step 4 − Add the following code to androidManifest.xml

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

Let's try to run your application. I assume you have connected your actual Android Mobile device with your computer. To run the app from android studio, open one of your project's activity files and click Run   icon from the toolbar. Select your mobile device as an option and then check your mobile device which will display your default screen –
