Using Clocks in Android

In this tutorial, we shall see how to display clocks in Android - Analog as well as Digital. The Analog clock displays two hands- one for hours and the other for minutes, while digital clock shows the hours, minutes and seconds in a digital format.

Note:- Analog and digital clocks can only be used to display time and cannot modify time. If you wish to modify time, use time picker instead.

1. Add the clocks in XML

Open the main.xml file and add AnalogClock and DigitalClock in XML.

File: res/layout/main.xml

<?xml version="1.0" encoding="utf-8"?>


<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"



    android:layout_width="fill_parent"



    android:layout_height="fill_parent"



    android:gravity="center"



    android:orientation="vertical" >

   
<TextView



        android:id="@+id/textView1"



        android:layout_width="wrap_content"



        android:layout_height="wrap_content"



        android:text="Analog Clock"



        android:textAppearance="?android:attr/textAppearanceLarge" />


   
<AnalogClock



        android:id="@+id/analogClock1"



        android:layout_width="wrap_content"



        android:layout_height="wrap_content" />


   
<TextView



        android:id="@+id/textView2"



        android:layout_width="wrap_content"



        android:layout_height="wrap_content"



        android:text="Digital Clock"



        android:textAppearance="?android:attr/textAppearanceLarge" />


<DigitalClock



        android:id="@+id/digitalClock1"



        android:layout_width="wrap_content"



        android:layout_height="wrap_content"



        android:text="DigitalClock" />


</LinearLayout>

2. Java Code

We shall display both the clocks in Java. We are not doing any manipulations out here.
File: Main.java

package com.endeavour.tutorial;



import android.app.Activity;




import android.os.Bundle;




import android.widget.AnalogClock;




import android.widget.DigitalClock;





public class Main extends Activity {



       @Override




       public void onCreate(Bundle savedInstanceState) {




              super.onCreate(savedInstanceState);




              setContentView(R.layout.main);



              AnalogClock ac = (AnalogClock) findViewById(R.id.analogClock1);



              //what you wish to do with AnalogClock goes here




              DigitalClock dc = (DigitalClock) findViewById(R.id.digitalClock1);



              //what you wish to do with DigitalClock goes here




       }



}

3. Output

Running the program will show you the following output.
