系统自带的DatePickerDialog只能一次性选择一个日期，有时候我们需要这样的功能：需要录入2个日期，比如开始日期和结束日期，如果采用DatePickerDialog需要弹出2次Dialog，能不能一次就搞定呢？那就需要下面的内容了。
自定义一个DatePickerDialog，实现OnDateChangedListener接口，里面有2个DatePicker，然后分别对这2个DatePicker设置日期就行了。

自定义Dialog：双日期选择器

package qianlong.qlmobile.view;

import qianlong.qlmobile.tablet.yinhe.hk.R;
import android.app.Dialog;
import android.content.Context;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.DatePicker;
import android.widget.DatePicker.OnDateChangedListener;

public class DatePickerDialog extends Dialog implements OnDateChangedListener{

private Context context;
private Button apply,cancel;
private DatePicker startDatePicker,endDatePicker;

private int start_year;
private int start_monthOfYear;
private int start_dayOfMonth;
private int end_year;
private int end_monthOfYear;
private int end_dayOfMonth;
public DatePickerDialog(Context context,
int start_year,
int start_monthOfYear,
int start_dayOfMonth,
int end_year,
int end_monthOfYear,
int end_dayOfMonth
            ) {
super(context);
// TODO Auto-generated constructor stub
this.context=context;
this.start_year=start_year;
this.start_monthOfYear=start_monthOfYear;
this.start_dayOfMonth=start_dayOfMonth;
this.end_year=end_year;
this.end_monthOfYear=end_monthOfYear;
this.end_dayOfMonth=end_dayOfMonth;

        init();
    }
public DatePickerDialog(Context context,int theme,
int start_year,
int start_monthOfYear,
int start_dayOfMonth,
int end_year,
int end_monthOfYear,
int end_dayOfMonth
            ) {
super(context);
// TODO Auto-generated constructor stub
this.context=context;
this.start_year=start_year;
this.start_monthOfYear=start_monthOfYear;
this.start_dayOfMonth=start_dayOfMonth;
this.end_year=end_year;
this.end_monthOfYear=end_monthOfYear;
this.end_dayOfMonth=end_dayOfMonth;
        init();
    }

private void init(){
// this.setCanceledOnTouchOutside(true);
this.setCancelable(true);
this.setTitle("日期选择器");
    }

@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
        setContentView(R.layout.ipo_dialog_date_picker);

        initViews();
        initValues();
    }

private void initViews(){
        apply=(Button)findViewById(R.id.apply);
        apply.setOnClickListener(clickListener);
        cancel=(Button)findViewById(R.id.cancel);
        cancel.setOnClickListener(clickListener);

        startDatePicker=(DatePicker)findViewById(R.id.startDatePicker);
        endDatePicker=(DatePicker)findViewById(R.id.endDatePicker);
    }
private void initValues(){
        startDatePicker.init(start_year, start_monthOfYear, start_dayOfMonth, this);
        endDatePicker.init(end_year, end_monthOfYear, end_dayOfMonth, this);
    }

private Button.OnClickListener clickListener=new Button.OnClickListener(){

@Override
public void onClick(View v) {
// TODO Auto-generated method stub
switch (v.getId()) {
case R.id.apply:
if(onDateSetListener!=null){
                    onDateSetListener.onDateSet(
                            start_year, start_monthOfYear, start_dayOfMonth,
                            end_year, end_monthOfYear, end_dayOfMonth
                            );
                }
                dismiss();
break;
case R.id.cancel:
                dismiss();
break;

default:
break;
            }
        }
    };

private OnDateSetListener onDateSetListener;
public interface OnDateSetListener {
void onDateSet(
int start_year,
int start_monthOfYear,
int start_dayOfMonth,
int end_year,
int end_monthOfYear,
int end_dayOfMonth
                );
    }
public void setOnDateSetListener(OnDateSetListener onDateSetListener){
this.onDateSetListener=onDateSetListener;
    }
@Override
public void onDateChanged(DatePicker view, int year, int monthOfYear,
int dayOfMonth) {
// TODO Auto-generated method stub
if(view==startDatePicker){
this.start_year=year;
this.start_monthOfYear=monthOfYear;
this.start_dayOfMonth=dayOfMonth;
        }else if(view==endDatePicker){
this.end_year=year;
this.end_monthOfYear=monthOfYear;
this.end_dayOfMonth=dayOfMonth;
        }
// updateDate(view,year,monthOfYear,dayOfMonth);

    }

// public void updateDate(
// DatePicker view, int year, int monthOfYear,int dayOfMonth){
// view.updateDate(year, monthOfYear, dayOfMonth);
// }

}

我只是简单的实现了一下，更多的扩展请大家添上。

ipo_dialog_date_picker.xml如下： 

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content"

<LinearLayout
 android:orientation="horizontal"
android:layout_width="fill_parent"

用法： 

private Calendar calendar_start = Calendar.getInstance();
private Calendar calendar_end = Calendar.getInstance();

//在需要的地方填入如下代码(通常是在Button的click事件中.)
qianlong.qlmobile.view.DatePickerDialog d=new qianlong.qlmobile.view.DatePickerDialog(
                            HK_TradeIPOActivity.this.getParent(),
                            calendar_start.get(Calendar.YEAR),
                            calendar_start.get(Calendar.MONTH),
                            calendar_start.get(Calendar.DAY_OF_MONTH),
                            calendar_end.get(Calendar.YEAR),
                            calendar_end.get(Calendar.MONTH),
                            calendar_end.get(Calendar.DAY_OF_MONTH)
                            );
                d.setOnDateSetListener(onDateSetListener);
                d.show();



//自己实现需要的功能
private qianlong.qlmobile.view.DatePickerDialog.OnDateSetListener onDateSetListener=new qianlong.qlmobile.view.DatePickerDialog.OnDateSetListener(){

        @Override
        public void onDateSet(int start_year,
                int start_monthOfYear,
                int start_dayOfMonth,
                int end_year,
                int end_monthOfYear,
                int end_dayOfMonth) {
            // TODO Auto-generated method stub

            SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy/MM/dd");

            calendar_start.set(Calendar.YEAR, start_year);
            calendar_start.set(Calendar.MONTH, start_monthOfYear);
            calendar_start.set(Calendar.DAY_OF_MONTH, start_dayOfMonth);


            calendar_end.set(Calendar.YEAR, end_year);
            calendar_end.set(Calendar.MONTH, end_monthOfYear);
            calendar_end.set(Calendar.DAY_OF_MONTH, end_dayOfMonth);

String startDate=simpleDateFormat.format(calendar_start.getTime());
String endDate=simpleDateFormat.format(calendar_end.getTime());
            //doSomething(startDate,endDate)    


        }

    };
