Create TimePicker Android App Using Android Studio

Introduction

Android is one of the most popular operating systems for mobile. In this article, I will show you how to create a TimePicker Android application using Android Studio.

Requirements

Android Studio version 2.3.3
Little bit XML and Java knowledge.
Android Emulator (or) Android mobile
Download link (Android Studio)

Steps to be followed

Follow these steps to create a Native TimePicker Android application using Android Studio. I have included the source code in the attachment.

Step 1

Open Android Studio and start a new Android Studio Project.

Step 2

You can choose your application name and choose where your project is stored on the location. If you wish to use C++ for coding the project, mark the "Include C++ support", and click the "Next" button.

Now, select the version of Android and select the target Android devices.

Step 3

Now, add the activity and click the "Next" button.

Add the activity name and click "Finish".

Step 4

Go to activity_main.xml. This XML file contains the designing code for an Android app in the activity_main.xml.

The XML code is given below.

<?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="abu.timepicker.MainActivity">
<TimePicker
android:id="@+id/simpleTimePicker"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_marginTop="50dp"
android:background="#0000FF"
android:padding="20dp"
android:timePickerMode="clock" />
<TextView
android:id="@+id/time"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:text="Time Is ::"
android:textColor="#008000"
android:textSize="20sp"
android:textStyle="bold" />
</RelativeLayout>

Step 5

Go to MainActivity.java. This Java program is the back-end language for Android.

The Java code is given below.

package abu.timepicker;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.app.TimePickerDialog;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.TextView;
import android.widget.TimePicker;
import android.widget.Toast;
public class MainActivity extends AppCompatActivity {
TextView time;
TimePicker firstTimePicker;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
time = (TextView) findViewById(R.id.time);
firstTimePicker = (TimePicker) findViewById(R.id.simpleTimePicker);
firstTimePicker.setIs24HourView(false); // used to display AM/PM mode
// perform set on time changed listener event
firstTimePicker.setOnTimeChangedListener(new TimePicker.OnTimeChangedListener() {
@Override
public void onTimeChanged(TimePicker view, int hourOfDay, int minute) {
// display a toast with changed values of time picker
Toast.makeText(getApplicationContext(), hourOfDay + " " + minute, Toast.LENGTH_SHORT).show();
time.setText(" Now Time is :: " + hourOfDay + " : " + minute);
}
});
}
}
