How to use DatePicker and Timepicker in Android _android

This article describes the use of DatePicker and Timepicker in Android in an example, as follows:
The following is the code that implements the specific functionality, where main.xml code is:

<?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:orientation=" vertical " > <textview android:id= "@+id/textview1" android:layout_width= wrap_content "android:layout_height=" WR Ap_content "android:text=" Please choose the time to buy this book "/> <datepicker android:id=" @+id/datepicker "Android:layout_wi" Dth= "Wrap_content" android:layout_height= "wrap_content" android:layout_gravity= "Center_horizontal"/> <Ti 
    Mepicker android:id= "@+id/timepicker" android:layout_width= "wrap_content" android:layout_height= "Wrap_content" android:layout_gravity= "Center_horizontal"/> <edittext android:id= "@+id/show" android:layout_width= "Wrap_content" android:layout_height= "Wrap_content" android:cursorvisible= "false" android:editable= "false"/&G

T
 </LinearLayout>

Java code is:

public class Androiddemo5activity extends activity {//log current time private int year;
 private int month;
 private int day;
 private int hour;

 private int minute; @Override protected void OnCreate (Bundle savedinstancestate) {//TODO auto-generated Method stub super.oncreate (Savedi
 Nstancestate);
 Setcontentview (R.layout.main);
 DatePicker date = (DatePicker) Findviewbyid (R.id.datepicker);
 Timepicker time = (timepicker) Findviewbyid (R.id.timepicker);
 Perhaps the current date of day, hour, minute Calendar CA = calendar.getinstance ();
 Year = Ca.get (calendar.year);
 month = Ca.get (calendar.month);
 Day = Ca.get (calendar.day_of_month);
 hour = Ca.get (Calendar.hour);

 minute = Ca.get (Calendar.minute); Initializes DatePicker Date.init (year, month, day, new Ondatechangedlistener () {@Override public void ondatechanged (datep
  Icker arg0, int year, int month, int day) {AndroidDemo5Activity.this.year = year;
  AndroidDemo5Activity.this.month = month;
  AndroidDemo5Activity.this.day = day; Show current time and date shOwdate (year, month, day, hour, minute);

 }

 }); Specifies the event listener Time.setontimechangedlistener for Timerpicker (new Ontimechangedlistener () {@Override public void Ontimechang
  Ed (timepicker arg0, int hour, int minute) {AndroidDemo5Activity.this.hour = hour;
  AndroidDemo5Activity.this.minute = minute;
 }
 }); } protected void Showdate (int year2, int month2, int day2, int hour2, int minute2) {edittext text = (edittext) findv
 Iewbyid (r.id.show);

 Text.settext ("Your purchase time is:" + year2 + "Year" + Month2 + "Month" + day2 + "Day" + HOUR2 + "Time" + Minute2 + "cent");

 }
}

The effect is as shown in the following illustration:
