DatePicker及DatePickerDialog的基本使用方法

1,调用showDialog(int id)方法

2,重写onCreateDialog(int id, Bundle arges)方法,传入相应参数,new一个DatePickerDialog对象.

3,实现onDateSetListener接口,并new一个该实现类的对象

4,重写onDateSetListener中的onDateSet()方法

具体代码如下:

package com.sun.datepicker;

import com.sun.datetimepicker.R;

import android.app.Activity;

import android.app.DatePickerDialog;

import android.app.Dialog;

import android.app.TimePickerDialog;

import android.app.DatePickerDialog.OnDateSetListener;

import android.os.Bundle;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.Button;

import android.widget.DatePicker;

import android.widget.TimePicker;

public class DatePickerTestActivity extends Activity {

/** Called when the activity is first created. */

Button testDatePicker = null;

DatePickerDialog datePickerDialog = null;

static final int SHOW_DATE_PICKER_DIALOG = 1;

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

testDatePicker = (Button)findViewById(R.id.testDatePicker);

testDatePicker.setOnClickListener(new OnClickListener() {

public void onClick(View v) {

// TODO Auto-generated method stub

showDialog(SHOW_DATE_PICKER_DIALOG);

}

});

}

DatePickerDialog.OnDateSetListener onDateSetListener = new DatePickerDialog.OnDateSetListener() {

public void onDateSet(DatePicker view, int year, int monthOfYear,

int dayOfMonth) {

// TODO Auto-generated method stub

System.out.println(year+"year "+(monthOfYear+1)+"month "+dayOfMonth+"day");

}

};

protected Dialog onCreateDialog(int id, Bundle args) {

// TODO Auto-generated method stub

if(id == SHOW_DATE_PICKER_DIALOG){

return new DatePickerDialog(this, onDateSetListener, 2012, 1, 6);

}

return null;

}

}
