简单的设置时间

 

      本文主要涉及DatePickerDialog与TimePickerDialog的使用，来看一个小小程序吧！作为一个Android小小白，把两个类合在了一起使用

本来还在想难道两个类都要同时继承Activity?!然后想想想，最后试试试！！终于把书上讲得两个类拼在了一起使用，单独得来设置日期与时刻，

的确，很多东西要去尝试才能得出结果，哪怕是错误的，至少你知道了，目前你的办法是行不通的。多尝试！这里直接把文件名设置成了TimePickDialogExample

具体TimePickDialogExample.java代码如下：

 1 package com.example.lenovo.A1103;
 2 
 3 
 4 import android.app.TimePickerDialog;
 5 import android.os.Bundle;
 6 import android.support.v7.app.AppCompatActivity;
 7 import android.view.View;
 8 import android.widget.Button;
 9 import android.widget.DatePicker;
10 import android.widget.TextView;
11 import android.widget.TimePicker;
12 
13 import java.util.Calendar;
14 import java.util.Date;
15 import java.util.Locale;
16 
17 public class TimePickerDialogExample extends AppCompatActivity {
18     private TextView showDate;
19     private Button setDate;
20     private TextView showTime;
21     private Button setTime;
22     private int year;
23     private int month;
24     private int day;
25     private int hours;
26     private int minus;
27 
28     @Override
29     protected void onCreate(Bundle savedInstanceState) {
30         super.onCreate(savedInstanceState);
31         setContentView(R.layout.activity_main);
32 
33         showDate = (TextView) findViewById(R.id.showDate);
34         setDate = (Button) findViewById(R.id.setDate);
35         showTime = (TextView) findViewById(R.id.showTime);
36         setTime = (Button) findViewById(R.id.setTime);
37 
38         Calendar myCalendar = Calendar.getInstance(Locale.CHINA);
39         Date myDate = new Date();
40         myCalendar.setTime(myDate);
41         year = myCalendar.get(Calendar.YEAR);     //获取Calendar对象中的年
42         month = myCalendar.get(Calendar.MONTH);
43         day = myCalendar.get(Calendar.DAY_OF_MONTH);
44         hours = myCalendar.get(Calendar.HOUR_OF_DAY);
45         minus = myCalendar.get(Calendar.MINUTE);
46         showDate.setText(year + "-" + (month + 1) + "-" + day);
47         showTime.setText(hours + ":" + minus);
48 
49         setDate.setOnClickListener(new View.OnClickListener() {
50             @Override
51             public void onClick(View v) {
52                 android.app.DatePickerDialog dpd = new android.app.DatePickerDialog(TimePickerDialogExample.this,
53                         new android.app.DatePickerDialog.OnDateSetListener() {
54                             @Override
55                             public void onDateSet(DatePicker view, int myYear, int monthOfYear, int dayOfMonth) {
56                                 showDate.setText(myYear + "-" + (monthOfYear + 1) + "-" + dayOfMonth);
57                                 year = myYear;
58                                 month = monthOfYear;
59                                 day = dayOfMonth;
60                             }
61                         }, year, month, day);
62                 //这是一整个构造函数，四个参数
63                 dpd.show();
64             }
65         });
66         setTime.setOnClickListener(new View.OnClickListener() {
67             @Override
68             public void onClick(View v) {
69                 TimePickerDialog tpd = new TimePickerDialog(TimePickerDialogExample.this,
70                         new TimePickerDialog.OnTimeSetListener() {
71                             @Override
72                             public void onTimeSet(TimePicker view, int hourOfDay, int myMinute) {
73                                 showTime.setText(hourOfDay + ":" + myMinute);
74                             }
75                         }, hours, minus, false);
76                 tpd.show();//显示TimePickerDialog组件
77             }
78         });
79 
80     }
81 
82 }
View Code

layout/main_xml代码如下：

 1 <LinearLayout
