android 时间控件的使用

一、样式文件time.xml

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

    <DatePicker
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/datePicker"
        android:layout_gravity="center_horizontal" />

    <TimePicker
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/timePicker"
        android:layout_gravity="center_horizontal" />
</LinearLayout>

二、activity文件：

package com.demo.yaokj.timedemo;

import android.app.DatePickerDialog;
import android.app.TimePickerDialog;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.DatePicker;
import android.widget.TimePicker;

import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;

public class MainActivity extends AppCompatActivity {
    private DatePicker datePicker;
    private TimePicker timePicker;
    private Calendar calendar;

    private int year ;
    private int month;
    private int dayOfMonth;
    private int hour;
    private int min;
    private int sec;

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

        datePicker = (DatePicker) findViewById(R.id.datePicker);
        timePicker = (TimePicker) findViewById(R.id.timePicker);

        calendar = Calendar.getInstance();
        year = calendar.get(Calendar.YEAR);
        month = calendar.get(Calendar.MONTH) + 1;
        dayOfMonth = calendar.get(Calendar.DAY_OF_MONTH) ;
        hour = calendar.get(Calendar.HOUR);
        min = calendar.get(Calendar.MINUTE);
        sec = calendar.get(Calendar.SECOND);

        setTitle(year+"-"+month+"-"+dayOfMonth+" "+hour+":"+min+":"+sec);

        //这里初始化
        datePicker.init(year, month, dayOfMonth, new DatePicker.OnDateChangedListener() {
            @Override
            public void onDateChanged(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
                setTitle(year+"-"+ (monthOfYear + 1) +"-"+dayOfMonth);
            }
        });

        timePicker.setOnTimeChangedListener(new TimePicker.OnTimeChangedListener() {
            @Override
            public void onTimeChanged(TimePicker view, int hourOfDay, int minute) {
                setTitle(year+"-"+ (month + 1) +"-"+dayOfMonth + " "+hourOfDay+":"+minute );
            }
        });

        new DatePickerDialog(this, new DatePickerDialog.OnDateSetListener() {
            @Override
            public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
                setTitle(year+"-"+ (monthOfYear + 1) +"-"+dayOfMonth);
            }
        },year,month,dayOfMonth).show();

        new TimePickerDialog(this, new TimePickerDialog.OnTimeSetListener() {
            @Override
            public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
                setTitle(year+"-"+ (month + 1) +"-"+dayOfMonth + " "+hourOfDay+":"+minute );
            }
        },hour,min,true).show();

    }
}
