    android:layout_height="match_parent"

        android:layout_height="wrap_content"

        android:layout_alignLeft="@+id/datePicker1"

        android:layout_alignParentBottom="true" />

</RelativeLayout>

2.activity

package com.example.datapickertimepicker;

import android.app.Activity;

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;

import android.widget.Toast;

public class MainActivity extends Activity {

    private DatePicker dpToday = null;

    private TimePicker tpNow = null;

    private Button btnSave = null;

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

        dpToday = (DatePicker)this.findViewById(R.id.datePicker1);

        tpNow = (TimePicker)this.findViewById(R.id.timePicker1);

        btnSave = (Button)this.findViewById(R.id.save);

        btnSave.setOnClickListener(new SaveOnClickListener());//给按钮添加一个事件

}

    private class SaveOnClickListener implements OnClickListener {

        @Override

        public void onClick(View v) {

               int iYear =  ;

               int iMonth = ;

               int iDay = ;

               String sDate ="";

               iYear = dpToday.getYear();//获取年

               iMonth = dpToday.getMonth()+;//获取月

               iDay = dpToday.getDayOfMonth();//获取日

               sDate = "日期 :"+String.valueOf(iYear)+"年"+String.valueOf(iMonth)+"月"+String.valueOf(iDay)+"日";

               int iHour = ;

               int iMinter = ;

               String sTim = "";

               iHour = tpNow.getCurrentHour();//获取当前的时

               iMinter = tpNow.getCurrentMinute();//获取当前的分钟

               sTim = "时间 :"+String.valueOf(iHour)+"时"+String.valueOf(iMinter)+"分";

               Toast.makeText(getApplicationContext(), sDate+" "+sTim, Toast.LENGTH_LONG).show();

        }
