How to use Calendar in Android?

Hello all…….

In today’s post I will show you how to useCalendar in android. Actually it is really easy to use calendar inandroid.
For that android provides a calendar widget.
We use calendar class to show the Calendar widget.

Here is the java source code for this example.

package com.coderzheaven.pack;

 

import java.util.Calendar;

import android.app.Activity;

import android.app.DatePickerDialog;

import android.app.Dialog;

import android.graphics.Color;

import android.os.Bundle;

import android.view.MotionEvent;

import android.view.View;

import android.widget.Button;

import android.widget.DatePicker;

import android.widget.EditText;

 

public class CalendarTestDemo extends Activity {

 

    String arrayMonth[] = {"Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sept","Oct","Nov","Dec"};

    Button date_button;

    static final int DATE_DIALOG_ID = 0;

    private int mYear;

    private int mMonth;

    private int mDay;

    EditText date_;

 

    @Override

    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.main);

 

        date_ = (EditText)findViewById(R.id.EditText01);

        date_.setTextColor(Color.RED);

        date_button = (Button)findViewById(R.id.Button01);

 

        date_button.setOnTouchListener(new View.OnTouchListener() {

            public boolean onTouch(View v, MotionEvent event)

            {

                showDialog(DATE_DIALOG_ID);

                return false;

            }

        });

 

        // get the current date

        final Calendar c = Calendar.getInstance();

        mYear = c.get(Calendar.YEAR);

        mMonth = c.get(Calendar.MONTH);

        mDay = c.get(Calendar.DAY_OF_MONTH);

 

        // display the current date (this method is below)

        updateDisplay();

 

    }

 

    private void updateDisplay() {

        date_.setText(

                new StringBuilder()

                        // Month is 0 based so add 1

                        .append(arrayMonth[mMonth]).append(" ")

                        .append(mDay).append(" ")

                        .append(mYear).append(" "));

    }

 

    private DatePickerDialog.OnDateSetListener mDateSetListener =

        new DatePickerDialog.OnDateSetListener() {

 

            public void onDateSet(DatePicker view, int year,

                                  int monthOfYear, int dayOfMonth) {

                mYear = year;

                mMonth = monthOfYear;

                mDay = dayOfMonth;

                updateDisplay();

            }

        };

        @Override

        protected Dialog onCreateDialog(int id) {

            switch (id) {

            case DATE_DIALOG_ID:

                return new DatePickerDialog(this,

                            mDateSetListener,

                            mYear, mMonth, mDay);

            }

            return null;

        }

 

}










This is the main.xml for the layout for the above java code.
