Ics Time Picker Example in Android

Download the following Libraries from the url : https://github.com/SimonVT . You will find list of libraries and download it which is circled in the below image.

Ensure you have added number picker library to the time picker libray.

And you should add this time picker libary to your project

activity_main.xml

MainActivity.java

package com.rajeshvijayakumar.timepicker;

import android.app.Activity;
import android.app.Dialog;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

import net.simonvt.app.TimePickerDialog;
import net.simonvt.widget.TimePicker;

import java.util.Calendar;

public class MainActivity extends Activity implements OnClickListener {

    private Button mTimeButton;

    private Calendar mCalen;
    private int hourOfDay;
    private int minute;
    private int ampm;

    private static final int Time_PICKER_ID = 0;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mTimeButton = (Button) findViewById(R.id.time_button);
        mCalen = Calendar.getInstance();
        hourOfDay = mCalen.get(Calendar.HOUR_OF_DAY);
        minute = mCalen.get(Calendar.MINUTE);
        ampm = mCalen.get(Calendar.AM_PM);
        mTimeButton.setOnClickListener(this);
    }

    @Override
    @Deprecated
    protected Dialog onCreateDialog(int id) {

        switch (id) {
            case Time_PICKER_ID:
                return new TimePickerDialog(this, TimePickerListener,
                        hourOfDay, minute, false);
        }
        return null;
    }

    private TimePickerDialog.OnTimeSetListener TimePickerListener =
            new TimePickerDialog.OnTimeSetListener() {

                // while dialog box is closed, below method is called.
                public void onTimeSet(TimePicker view, int hour, int minute) {

                    mCalen.set(Calendar.HOUR_OF_DAY, hour);
                    mCalen.set(Calendar.MINUTE, minute);

                    int hour12format = mCalen.get(Calendar.HOUR);
                    hourOfDay = mCalen.get(Calendar.HOUR_OF_DAY);
                    minute = mCalen.get(Calendar.MINUTE);
                    ampm = mCalen.get(Calendar.AM_PM);
                    String ampmStr = (ampm == 0) ? "AM" : "PM";
                    // Set the Time String in Button
                    mTimeButton.setText(hour12format + " : " + minute + " / " + ampmStr);
                }
            };

    @Override
    public void onClick(View v) {
        showDialog(Time_PICKER_ID);
    }
}

styles.xml

In Manifest.xml give android:theme="@style/SampleTheme"

Download the following Libraries from the url : https://github.com/SimonVT . You will find list of libraries and download it which is circled in the below image.

Ensure you have added calendarview and number picker library to the date picker libray.

And your project should add this date picker library as follows :

activity_dialog.xml

IcsDatePickerActivity.java

package com.rajeshvijayakumar.datepicker;

import android.app.Activity;
import android.app.Dialog;
import android.os.Bundle;

public class MainActivity extends Activity implements OnClickListener {

    private Button mDateButton;

    private Calendar mCalen;
    private int day;
    private int month;
    private int year;

    private static final int DATE_PICKER_ID = 0;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mDateButton = (Button) findViewById(R.id.date_button);
        mCalen = Calendar.getInstance();
        day = mCalen.get(Calendar.DAY_OF_MONTH);
        month = mCalen.get(Calendar.MONTH);
        year = mCalen.get(Calendar.YEAR);
        mDateButton.setOnClickListener(this);
    }

    @Override
    @Deprecated
    protected Dialog onCreateDialog(int id) {

        switch (id) {
            case DATE_PICKER_ID:
                return new DatePickerDialog(this, datePickerListener,
                        year, month, day);
        }
        return null;
    }

    private DatePickerDialog.OnDateSetListener datePickerListener =
            new DatePickerDialog.OnDateSetListener() {

                // while dialog box is closed, below method is called.
                public void onDateSet(DatePicker view, int selectedYear,
                        int selectedMonth, int selectedDay) {
                    year = selectedYear;
                    month = selectedMonth;
                    day = selectedDay;

                    // Set the Date String in Button
                    mDateButton.setText(day + " / " + (month + 1) + " / " + year);
                }
            };

    @Override
    public void onClick(View v) {

        showDialog(DATE_PICKER_ID);

    }
}

styles.xml

In Manifest.xml give android:theme="@style/SampleTheme"

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