定义的布局文件：

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

    <DatePicker
        android:id="@+id/datePicker"
        android:layout_width="match_parent"
        android:layout_height="400dp"
        android:startYear="2000"
        android:endYear="2017"
        android:calendarViewShown="true"
        android:spinnersShown="true"
        />

    <TextView
        android:id="@+id/showText"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        />

</LinearLayout>

主程序文件：

package com.toby.personal.testlistview;

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.widget.DatePicker;
import android.widget.TextView;

import java.util.Calendar;

public class MainActivity extends AppCompatActivity {

    final private static String TAG = "Toby_Test";

    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);

        final Calendar c = Calendar.getInstance();
        year = c.get(Calendar.YEAR);
        month = c.get(Calendar.MONTH);
        day = c.get(Calendar.DATE);
        hour = c.get(Calendar.HOUR);
        minute = c.get(Calendar.MINUTE);

        final DatePicker datePicker = (DatePicker) findViewById(R.id.datePicker);
        datePicker.init(year, month, day, new DatePicker.OnDateChangedListener() {
            @Override
            public void onDateChanged(DatePicker datePicker, int y, int m, int d) {
                year = y;
                month = m;
                day = d;
                showDate(y, m, d, hour, minute);
            }
        });

        showDate(year, month, day, hour, minute);
    }

    private void showDate(int y, int M, int d, int h, int m) {
        TextView showText = (TextView) findViewById(R.id.showText);
        showText.setText("Current Datetime: " + y + "/" + (M + 1) + "/" + d + " " + h + ":" + m);
    }

}
