3. spring版 timer HelloWorld
1. 由于这回需要使用Spring的jar包，所以需要修改pom文件，添加如下依赖：

<!-- Spring framework -->

<dependency>

	<groupId>org.springframework</groupId>

	<artifactId>spring</artifactId>

	<version>2.5.6</version>

</dependency>

注：如果使用3.0版本就不是只改个版本号的问题了，因为spring3.0已经分包了。

2. 编写Timer类代码：

package com.helloworld.common;



public class SayHelloTask{



	public void sayHello() {

		System.out.println("HelloWorld");

	}



}

注意：此domain类完全没有依赖任何接口！！！
3. 编写spring配置文件：这个代码比较多就不全贴上去了

<bean id="sayHelloTask"  />

首先是上面那个bean的声明。

<bean id="schedulerTask" >
		<property name="targetObject" ref="sayHelloTask" />
		<property name="targetMethod" value="sayHello" />
	</bean>
MethodInvokingTimerTaskFactoryBean 取代了JDK中的TimerTask

<bean id="timerTask"
		>
		<property name="timerTask" ref="schedulerTask" />
		<property name="delay" value="2000" />
		<property name="period" value="6000" />
	</bean>

这个取代了JDK中的Timer

<bean >
		<property name="scheduledTimerTasks">
			<list>
				<ref local="timerTask" />
			</list>
		</property>
	</bean>

定义一个TimerFactoryBean来启动Task。
4. 编写测试代码：

public class Test {
	public static void main(String[] args) {
		ApplicationContext context = new ClassPathXmlApplicationContext("Spring-Scheduler.xml");
		
	}
}

OK 一切运行成功。

显示PopupWindow
        PopupWindow可以实现浮层效果，而且可以自定义显示位置，出现和退出时的动画，比如新浪微博顶部栏的微博分组就是用PopupWindow实现的。

        一、实例化PopupWindow，这里用R.layout.group_list填充mPopupWindow，并指定宽高。

mPopupLayout = getLayoutInflater().inflate(R.layout.group_list, null);
mPopupWindow = new PopupWindow(mPopupLayout, width, height, true);

        二、指定PopupWindow的显示位置

//mAncorView是页面中的某个View，默认是将mPopupWindow与mAncorView的左下角对齐，如果空间不够显示，则将将mPopupWindow与mAncorView的左上角对齐。offsetX和offsetY是mPopupWindow位置的相对偏移，很容易理解。
		mPopupWindow.showAsDropDown(mAncorView, offsetX, offsetY);

也可使用下面方法

//下面的方法是用屏幕上的绝对坐标显示，mPopupWindow
//我们往往不知道mPopupWindow要显示的精确位置，通常先计算页面上某个元素mView的位置，在进行偏移
		
//得到mView在屏幕中的坐标
int [] pos = new int[2];
mView.getLocationOnScreen(pos);
offsetY = pos[1] + mView.getHeight();
offsetX = 0;
		
//显示mPopupWindow
mPopupWindow.showAtLocation(mView, Gravity.TOP|Gravity.CENTER_HORIZONTAL, offsetX, offsetY);//这里的第一个参数没搞明白什么用，android官方文档说是为了获取token

        三、为PopupWindow指定动画
先定义动画
PopupWindow出现时的动画，popup_enter.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <scale android:fromXScale="0.6" android:toXScale="1.0"
        android:fromYScale="0.6" android:toYScale="1.0" android:pivotX="50%"
        android:pivotY="50%" android:duration="1000" />

    <alpha android:interpolator="@android:anim/decelerate_interpolator"
        android:fromAlpha="0.0" android:toAlpha="1.0" android:duration="1000" />
</set>

PopupWindow消失时的动画，popup_exit.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <scale
        android:fromXScale="1.0"
        android:toXScale="0.5"
        android:fromYScale="1.0"
        android:toYScale="0.5"
        android:pivotX="50%"
        android:pivotY="50%"
        android:duration="500" />

    <alpha
        android:interpolator="@android:anim/accelerate_interpolator"
        android:fromAlpha="1.0"
        android:toAlpha="0.0"
        android:duration="500" />
</set>

再设定动画的style

<style name="PopupAnimation" parent="android:Animation">
    <item name="android:windowEnterAnimation">@anim/popup_enter</item>
    <item name="android:windowExitAnimation">@anim/popup_exit</item>
</style>

最后通过Java代码设置动画

mPopupWindow.setAnimationStyle(R.style.PopupAnimation);
