绘制时间选择器的布局 common_datetime

<?xml version="1.0" encoding="utf-8"?>
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

            android:id="@+id/datepicker"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:startYear="0"

//影藏日历

android:calendarViewShown="false"

//设置主题改变样式

        android:theme="@android:style/Theme.Holo.Light"
        android:endYear="9999"
         />

            android:id="@+id/timepicker"
        android:visibility="gone"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

目前只知道这么几个主题：

//滑动型

android:theme="@android:style/Theme.Holo.Light"

//下面连个是按钮型
android:theme="@android:style/Theme.Light.NoTitleBar"
android:theme="@android:style/Theme.Light"

准备好这些之后，开始使用，在需要使用的activity中设置监听
日期时间选择控件使用方法：

private TextView inputDate;//需要设置的日期时间文本框

private String initDateTime="2012年9月3日 14:44",//初始日期时间值在点击事件中使用：

inputDate.setOnClickListener(new OnClickListener() {
@Override public void onClick(View v) {

//将展示文本和默认时间传过去

DateTimePickDialogUtil dateTimePicKDialog=new DateTimePickDialogUtil(this,initDateTime);

dateTimePicKDialog.dateTimePicKDialog(inputDate);

} });

OK,完工
