易采站长站为您分析Android中TimePicker时间选择与DatePicker日期选择组件的使用实例,这两个组件加上去的效果就是我们平时在iOS上设置闹钟时调整时间类似的滚动选项,需要的朋友可以参考下
效果和代码都非常直观：
实例1：TimePicker
<RelativeLayout xmlns:android="http://www.easck.com/apk/res/android"
xmlns:tools="http://www.easck.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
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=".MainActivity" >
<TimePicker
android:id="@+id/timePic1"
android:layout_height="wrap_content"
android:layout_width="match_parent"/>
<Button
android:id="@+id/buttone1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="@id/timePic1"
android:text="获取TimePick时间"/>
</RelativeLayout>
