<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">



    <DatePicker
        android:id="@+id/datePickerView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:calendarViewShown="true"
        android:datePickerMode="calendar"
        android:layout_gravity="center_horizontal" />

</android.support.constraint.ConstraintLayout>

代码:

package com.example.user.datapicker;

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

import java.util.Calendar;

public class MainActivity extends AppCompatActivity {
    DatePicker datePicker;

    int year,mouth,day,hour,min;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        datePicker = (DatePicker)findViewById(R.id.datePickerView);

        // get time
        Calendar cal = Calendar.getInstance();
        year = cal.get(Calendar.YEAR);
        mouth =  cal.get(Calendar.MONTH);
        day = cal.get(Calendar.DAY_OF_MONTH);
        hour = cal.get(Calendar.HOUR);
        min = cal.get(Calendar.MINUTE);

        datePicker.init(year, mouth, day, new DatePicker.OnDateChangedListener() {
            @Override
            public void onDateChanged(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
                MainActivity.this.year = year;
                MainActivity.this.mouth = monthOfYear;
                MainActivity.this.day = dayOfMonth;

                //显示用户选择的日期
