1，activity代码：

package com.example.fitness_app.web.teacher;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.DatePicker;
import android.widget.EditText;
import android.widget.TimePicker;

import com.example.fitness_app.R;

public class teacher_addcourseActivity extends AppCompatActivity implements DatePicker.OnDateChangedListener {
    private int Year;
    private  int month;
    private  int day;
    private  int hour;
    private  int min;

    private  EditText editText = null;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_teacher_addcourse);

        //时间控件
        editText = findViewById(R.id.edittime);
        DatePicker datePicker = findViewById(R.id.coursdaydate);
        datePicker.init(Year,month,day,this);
//        TimePicker timePicker = new TimePicker();


        TimePicker timePicker = findViewById(R.id.coursdaytime);
        timePicker.setIs24HourView(true);
//        editText.setText(Year+"-"+month+"-"+day+" "+hour+":"+min);
        timePicker.setOnTimeChangedListener(new TimePicker.OnTimeChangedListener() {
            @Override
            public void onTimeChanged(TimePicker view, int hourOfDay, int minute) {
                hour = hourOfDay;
                min = minute;
                if (minute<10){
                    hour = hourOfDay;
                    min = minute;
                    Log.i("time","小时"+hour+"分钟"+"0"+min);
                    editText.setText(Year+"-"+month+"-"+day+" "+hour+":"+min);
                }else {

                    Log.i("time","小时"+hour+"分钟"+min);
                    editText.setText(Year+"-"+month+"-"+day+" "+hour+":"+min);

                }
            }
        });
    }



    @Override
    public void onDateChanged(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
        month = monthOfYear +1;
        Year = year;
        day = dayOfMonth;
        Log.i("shijian",Year+"年"+month+"月"+day+"日");
        editText.setText(Year+"-"+month+"-"+day+" "+hour+":"+min);
    }
}

2，xml代码

<RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <DatePicker
            android:id="@+id/coursdaydate"
            android:layout_height="150dp"
            android:layout_width="200dp"
            android:datePickerMode="spinner"
            android:calendarViewShown="false"
            android:startYear="2020"
            android:scrollbarSize="10dp"
            />
        <TimePicker
            android:id="@+id/coursdaytime"
            android:layout_toRightOf="@id/coursdaydate"
            android:layout_width="wrap_content"
            android:layout_height="150dp"
            android:timePickerMode="spinner"></TimePicker>
