本文介绍如何在Android应用中创建日期和时间选择器。通过整合DatePicker与TimePicker控件，并结合Activity逻辑，用户可以轻松选择特定日期及时间。文章详细展示了布局文件配置与Activity代码实现。

【1】创建工程DateTimePicker,结构如图：

【2】在布局文件中分别增加DatePicker与TimePicker控件，如下：

【3】在Activity中实现逻辑

package com.beijing.datetimepicker; import java.util.Calendar; import android.app.Activity; import android.app.DatePickerDialog; import android.app.DatePickerDialog.OnDateSetListener; import android.app.TimePickerDialog; import android.app.TimePickerDialog.OnTimeSetListener; import android.os.Bundle; import android.widget.DatePicker; import android.widget.DatePicker.OnDateChangedListener; import android.widget.TimePicker; import android.widget.TimePicker.OnTimeChangedListener; public class MainActivity extends Activity { private DatePicker datePicker; private TimePicker timePicker; private Calendar cal; private int year; private int month; private int day; private int hour; private int minute; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); //获取一个日历的实例 cal=Calendar.getInstance(); //获取年月日时分秒的信息 year=cal.get(Calendar.YEAR); month=cal.get(Calendar.MONTH)+1; day=cal.get(Calendar.DAY_OF_MONTH); hour=cal.get(Calendar.HOUR_OF_DAY); minute=cal.get(Calendar.MINUTE); setTitle(year+"-"+month+"-"+day+"-"+hour+":"+minute); datePicker=(DatePicker) findViewById(R.id.datePicker); timePicker=(TimePicker) findViewById(R.id.timePicker); //datePicker初始化 datePicker.init(year, cal.get(Calendar.MONTH), day, new OnDateChangedListener() { @Override public void onDateChanged(DatePicker view, int year, int monthOfYear, int dayOfMonth) { setTitle(year+"-"+(monthOfYear+1)+"-"+dayOfMonth); } }); timePicker.setOnTimeChangedListener(new OnTimeChangedListener() { @Override public void onTimeChanged(TimePicker view, int hourOfDay, int minute) { setTitle(hourOfDay+":"+minute); } }); new DatePickerDialog(this, new OnDateSetListener() { @Override public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) { setTitle(year+"-"+(monthOfYear+1)+"-"+dayOfMonth); } }, year, cal.get(Calendar.MONTH), day).show(); new TimePickerDialog(this, new OnTimeSetListener() { @Override public void onTimeSet(TimePicker view, int hourOfDay, int minute) { setTitle(hourOfDay+":"+minute); } }, hour, minute, true).show(); } }
