·         Start a new project named TimePickerDemo.

·         Open the res/layout/main.xml file and insert the following:

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

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

     android:orientation="vertical"

     android:layout_width="fill_parent"

     android:layout_height="fill_parent">

<TextView

        android:id="@+id/timeDisplay" 

     android:layout_width="fill_parent"

     android:layout_height="wrap_content"

     android:layout_marginTop="10dp"

     android:text="@string/hello"/>

<Button

        android:id="@+id/timePicker"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:layout_marginTop="10dp"

        android:text="Change the time"/>

</LinearLayout>

Open the activity file and add the following code as shown below:

import java.util.Calendar;

import android.app.Activity;

import android.app.Dialog;

import android.app.TimePickerDialog;

import android.os.Bundle;

import android.view.View;

import android.widget.Button;

import android.widget.TextView;

import android.widget.TimePicker;

 

public class TimePickerActivity extends Activity { 

        private TextView mTimeDisplay; 
        private Button mPickTime; 
        private int mHour; 
        private int mMinute; 

        static final int TIME_DIALOG_ID=0; 

     @Override 
     public void onCreate(Bundle savedInstanceState) { 
         super.onCreate(savedInstanceState); 
         setContentView(R.layout.main); 

         // capture our View elements 
         mTimeDisplay = (TextView) findViewById(R.id.timeDisplay); 
         mPickTime=(Button)findViewById(R.id.timePicker); 

         // add a click listener to the button 
         mPickTime.setOnClickListener(new View.OnClickListener() { 

                      public void onClick(View v) { 

                           showDialog(TIME_DIALOG_ID); 
                     } 
              }); 

         // get the current time 
         final Calendar c=Calendar.getInstance(); 
         mHour=c.get(Calendar.HOUR_OF_DAY); 
         mMinute=c.get(Calendar.MINUTE); 

         // display the current date 
         updateDisplay(); 
    } 

     // updates the time we display in the TextView 
     private void updateDisplay() 
    { 
         mTimeDisplay.setText(new 
                StringBuilder().append(pad( 
               StringBuilder().append(pad(mHour)).append(":").append(pad(mMinute))); 
    } 

        private Object pad(int mMinute2) { 

               if(mMinute2>=10) 
                      return String.valueOf(mMinute2); 
               else 
                      return "0"+String.valueOf(mMinute2); 
       } 

        // the callback received when the user "sets" the time in the dialog 
        private TimePickerDialog.OnTimeSetListener mtimeSetListener=new 
                                             TimePickerDialog.OnTimeSetListener() { 
                                            TimePickerDialog.OnTimeSetListener() { 

               public void onTimeSet(TimePicker view, int hourOfDay, int minute) { 

                      mHour=hourOfDay; 
                      mMinute=minute; 
                     updateDisplay(); 
              } 
       }; 

        @Override 
        protected Dialog onCreateDialog(int id) 
       { 
           switch(id) 
          { 
             case TIME_DIALOG_ID: 
               return new TimePickerDialog(this,mtimeSetListener,mHour,mMinute,false); 
          } 
           return null; 
       } 
}

·         Run the application.
Output will something like below:

When you click on the button (Change the time), a time picker dialog will open, you can set the time from the time picker dialog.

After setting the time, a new time will display in the TextView.
