同时选择日期和时间的对话框DateTimePickDialog

1.布局文件res/layout/comm_datetime.xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="fill_parent"    android:layout_height="wrap_content"    android:gravity="center"    android:orientation="vertical" >    <DatePicker        android:id="@+id/datepicker"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:calendarViewShown="false"        android:datePickerMode="spinner"        android:descendantFocusability="blocksDescendants" />    <TimePicker        android:id="@+id/timepicker"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:timePickerMode="spinner" /></LinearLayout>

2.日期时间选择器类DateTimePickDialog.java

import java.util.Calendar;import android.app.AlertDialog;import android.content.Context;import android.content.DialogInterface;import android.content.DialogInterface.OnClickListener;import android.view.LayoutInflater;import android.view.View;import android.widget.DatePicker;import android.widget.Toast;import android.widget.DatePicker.OnDateChangedListener;import android.widget.TimePicker;import android.widget.TimePicker.OnTimeChangedListener;public class DateTimePickDialog implements OnDateChangedListener,        OnTimeChangedListener {    private Context mContext;    private DatePicker dp;    private TimePicker tp;    private int year;    private int monthOfYear;    private int dayOfMonth;    private int hourOfDay;    private int minute;    private Calendar c;    private OnDateTimeSetListener mListener;    public DateTimePickDialog(Context context, Calendar c) {        this.mContext = context;        this.c = c;        year = c.get(Calendar.YEAR);        monthOfYear = c.get(Calendar.MONTH);        dayOfMonth = c.get(Calendar.DAY_OF_MONTH);        hourOfDay = c.get(Calendar.HOUR_OF_DAY);        minute = c.get(Calendar.MINUTE);        init();    }    private void init() {        View view = LayoutInflater.from(mContext).inflate(                R.layout.comm_datetime, null);        dp = (DatePicker) view.findViewById(R.id.datepicker);        tp = (TimePicker) view.findViewById(R.id.timepicker);        dp.init(year, monthOfYear, dayOfMonth, this);        tp.setCurrentHour(hourOfDay);        tp.setCurrentMinute(minute);        tp.setOnTimeChangedListener(this);        AlertDialog.Builder b = new AlertDialog.Builder(mContext);        b.setTitle("请选择时间");        b.setView(view);        //点击确定，回调数据        b.setPositiveButton("确定", new OnClickListener() {            @Override            public void onClick(DialogInterface dialog, int which) {                Toast.makeText(                        mContext,                        "" + year + "-" + (monthOfYear + 1) + "-" + dayOfMonth                                + " " + hourOfDay + ":" + minute,                        Toast.LENGTH_SHORT).show();                if (null != mListener) {                    mListener.onDateTimeSet(dp, tp, year, monthOfYear,                            dayOfMonth, hourOfDay, minute);                }            }        });        //取消后恢复原来选择的时间        b.setNegativeButton("取消", new OnClickListener() {            @Override            public void onClick(DialogInterface dialog, int which) {                // TODO Auto-generated method stub                if (null != mListener) {                    mListener.onDateTimeSet(dp, tp, c.get(Calendar.YEAR),                            c.get(Calendar.MONTH),                            c.get(Calendar.DAY_OF_MONTH),                            c.get(Calendar.HOUR_OF_DAY), c.get(Calendar.MINUTE));                }            }        });        b.create().show();    }    @Override    public void onTimeChanged(TimePicker view, int hourOfDay, int minute) {        // TODO Auto-generated method stub        this.tp = view;        this.hourOfDay = hourOfDay;        this.minute = minute;    }    @Override    public void onDateChanged(DatePicker view, int year, int monthOfYear,            int dayOfMonth) {        // TODO Auto-generated method stub        this.dp = view;        this.year = year;        this.monthOfYear = monthOfYear;    }    public void setOnDateTimeSetListener(OnDateTimeSetListener listener) {        this.mListener = listener;    }    public interface OnDateTimeSetListener {        void onDateTimeSet(DatePicker dp, TimePicker tp, int year,                int monthOfYear, int dayOfMonth, int hourOfDay, int minute);    }}

3.程序中使用：

new DateTimePickDialog(DialogTest.this,c).setOnDateTimeSetListener(new OnDateTimeSetListener() {//给定Calendar c,就能将日期和时间进行初始化                @Override                public void onDateTimeSet(DatePicker dp, TimePicker tp, int year,                        int monthOfYear, int dayOfMonth, int hourOfDay, int minute) {                    // 保存选择后时间                    c.set(Calendar.YEAR, year);                    c.set(Calendar.MONTH, monthOfYear);                    c.set(Calendar.DAY_OF_MONTH, dayOfMonth);                    c.set(Calendar.HOUR_OF_DAY, hourOfDay);                    c.set(Calendar.MINUTE, minute);                }            });
