android 里面一些关于时间的组件

1. DatePicker 供用户选择日期；TimePicker 供用户选择时间。我所使用的开发工具：AndroidStudio1.5

如果程序需要获取用户选择的日期，时间，则可通过为 DatePicker 添加 OnDateChangeListener 进行监听；为 TimePicker 添加 OnTimerChangedListener 进行监听。效果如下(如果不能选择日期，时间，可能是主题的原因)：



content_main.xml 布局文件：

<span style="font-size:18px;"><?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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"
android:orientation="vertical"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
app:layout_behavior="@string/appbar_scrolling_view_behavior"
tools:context="com.scxh.choosedate.MainActivity"
tools:showIn="@layout/activity_main">

<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="选择的时间" />

<!-- android:calendarViewShown="" 设置日期选择器是否显示 CalendarView 组件
android:spinnersShown="" 设置日期选择器是否显示 Spinner 日期选择组件-->
<DatePicker
android:id="@+id/datePicker"
android:layout_gravity="center_horizontal"
android:startYear="2000"
android:endYear="2016"
android:calendarViewShown="true"
android:spinnersShown="true"
android:layout_width="wrap_content"
android:layout_height="280dp">
</DatePicker>

<TimePicker
android:id="@+id/timePicker"
android:layout_gravity="center_horizontal"
android:layout_width="wrap_content"
android:layout_height="100dp">
</TimePicker>

<EditText
android:id="@+id/show"
android:editable="false"
android:cursorVisible="false"
android:layout_width="match_parent"
android:layout_height="wrap_content" />

</LinearLayout>
</span>

MainActivity.java ：

<span style="font-size:18px;">package com.scxh.choosedate;

import android.os.Bundle;
import android.support.design.widget.FloatingActionButton;
import android.support.design.widget.Snackbar;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.view.View;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.DatePicker;
import android.widget.EditText;
import android.widget.TimePicker;

import java.util.Calendar;

public class MainActivity extends AppCompatActivity {

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);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);

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

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

// 初始化 DatePicker，初始化时指定监听器
datePicker.init(year, month, day, new DatePicker.OnDateChangedListener() {
@Override
public void onDateChanged(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
MainActivity.this.year = year;
MainActivity.this.month = month;
MainActivity.this.day = day;
// 显示当前的时间
showDate(year, month, day, hour, minute);
}
});

timePicker.setOnTimeChangedListener(new TimePicker.OnTimeChangedListener() {
@Override
public void onTimeChanged(TimePicker view, int hourOfDay, int minute) {
MainActivity.this.hour = hourOfDay;
MainActivity.this.minute = minute;

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

private void showDate(int year, int month, int day, int hour, int minute) {
EditText show = (EditText)findViewById(R.id.show);
show.setText("你选择的日期：" + year + "年"
+ (month + 1) + "月" + day + "日 "
+ hour + "时" + minute + "分");
}

}
</span>

2. 日历视图 CalendarView 组件：

CalendarView 可用于显示和选择日期，也可以通过触摸来滚动日历，如果需要监听该组件日期的改变，可调用 setOnDateChangeListener() 方法来为该组件添加点击事件监听器。下面只是一个简单的实例，效果如下：

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

android:paddingTop="@dimen/activity_vertical_margin"
app:layout_behavior="@string/appbar_scrolling_view_behavior"
tools:context="com.crazy.simpleui.MainActivity"
tools:showIn="@layout/activity_main">

<TextView
android:text="选择你想选择的时间："
android:layout_width="match_parent"
android:layout_height="wrap_content" />

<!--设置以星期一为每周的第一天，
设置共显示4个星期,
android:weekNumberColor 设置显示周编号的颜色
android:selectedWeekBackgroundColor 被选定周的背景颜色
android:focusedMonthDateColor 获取焦点的月份的日期颜色
android:weekSeparatorLineColor 设置周分割线的颜色-->
<CalendarView
android:id="@+id/calendarView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:firstDayOfWeek="2"
android:shownWeekCount="4"
android:weekNumberColor="#00f"
android:selectedWeekBackgroundColor="#999"
android:focusedMonthDateColor="#0f0"
android:weekSeparatorLineColor="#ff0"
android:unfocusedMonthDateColor="#f5f">

</CalendarView>
</LinearLayout>

MainActivity.java :

package com.crazy.simpleui;

import android.os.Bundle;
import android.support.design.widget.FloatingActionButton;
import android.support.design.widget.Snackbar;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.view.View;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.CalendarView;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);

CalendarView calendarView = (CalendarView)findViewById(R.id.calendarView);

calendarView.setOnDateChangeListener(new CalendarView.OnDateChangeListener() {
@Override
public void onSelectedDayChange(CalendarView view, int year,
int month, int dayOfMonth) {

Toast.makeText(MainActivity.this, "你选择的日期是：" + year + "年"
+ month + "月" + dayOfMonth + "日", Toast.LENGTH_SHORT).show();
}
});
}

}
