Read DatePicker and TimePicker


package com.example.androiddatepicker;

import java.util.Calendar;
import android.os.Bundle;
import android.app.Activity;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.DatePicker;
import android.widget.TextView;
import android.widget.TimePicker;

public class MainActivity extends Activity{

DatePicker pickerDate;
TimePicker pickerTime;
Button buttonReadPicker;
TextView info;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

info = (TextView)findViewById(R.id.info);
pickerDate = (DatePicker)findViewById(R.id.pickerdate);
pickerTime = (TimePicker)findViewById(R.id.pickertime);

Calendar now = Calendar.getInstance();

pickerDate.init(
now.get(Calendar.YEAR),
now.get(Calendar.MONTH),
now.get(Calendar.DAY_OF_MONTH),
null);

pickerTime.setCurrentHour(now.get(Calendar.HOUR_OF_DAY));
pickerTime.setCurrentMinute(now.get(Calendar.MINUTE));

buttonReadPicker = (Button)findViewById(R.id.readpicker);
buttonReadPicker.setOnClickListener(new OnClickListener(){

@Override
public void onClick(View arg0) {
Calendar cal = Calendar.getInstance();
cal.set(pickerDate.getYear(),
pickerDate.getMonth(),
pickerDate.getDayOfMonth(),
pickerTime.getCurrentHour(),
pickerTime.getCurrentMinute(),
00);

info.setText(cal.toString());

}});
}

}
