【前言】

因为要加强 Android 投影仪的 luncher 倒影国际化的功能，所以开始的时候在BroderView的基础改了些东西.

后来又一些BUG，修复了，感觉毕竟是用的别人的开源代码，如果不开源又不好意思，再说了，这个代码也不属于

在职期间开发，是业余时间编写，所以没有什么问题.欢迎大家多多指教.

【Android-tv-widget】

Android 组件，主要用于 投影仪，TV电视，手机等等Android设备.

需要定制luncher桌面的请不要联系我.

移动边框，焦点控件动画.

高斯模糊(毛玻璃效果)

图片主色

目录结构：

--com/androidtv/activity

----activity.java : 测试demo

--com/androidtv/color (获取图片颜色主色和其它颜色)

----ColorArt.java ：

----HashBag.java

--com/androidtv/utils (一些常用函数)

----AnimUtils.java

----DensityUtil.java

----FastBlur.java ：高斯模糊

----ImageUtils.java

--com/androidtv/view

----BorderView.java ：移动边框

----CopyOfCopyOfFocusBorderView.java

----FocusBorderView.java

----FocusRelativeLayout.java

----ReflectionRelativeLayout.java

----VerticalSmoothGridView.java

--net.qiujuer.imageblurring.jni (高斯模糊JNI)

例子图片查看

注意

如果想在GridView上加上BorderView，只需要调用 runTranslateAnimation

最近找了一种新的方法，可以在最上面放大... ....布局只需要将需要放大的房在最上层
