Android 时间控件2.钟表

1.AnalogClock圆形时钟；DigitalClock电子时钟；这两个时钟是不允许用户改变的。

    <AnalogClock        android:layout_width="wrap_content"        android:layout_height="wrap_content" />    <DigitalClock        android:layout_width="wrap_content"        android:layout_height="wrap_content"         android:textSize="18sp"/>

2.如何设定一段时间：例如设定起始时间和结束时间

首先看TimePickerDialog的构造方法：

什么时候使用TimePickerDialog.OnTimeSetListener callBack：当点击dialog中的完成时调用实现此接口的类

3.代码实现

布局文件activity_main.xml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    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"    tools:context="com.example.android_anlogclock.MainActivity" >    <AnalogClock        android:layout_width="wrap_content"        android:layout_height="wrap_content" />    <DigitalClock        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:textSize="18sp" />    <Button        android:id="@+id/button1"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:text="显示TimePickerDialog" />    <Button        android:id="@+id/button2"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:text="显示DatePickerDialog" />    <TextView        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="@string/hello_world" /></LinearLayout>
