当HTC手机关闭酷的视觉效果 [英] Cool visual effect when an HTC phone is turning off

问题描述

请你知道如何实现在Android的这种效果（模糊的背景）？

please do you know how to achieve this effect (blur on the background) in Android?

我的HTC野火做到这一点时，即将被关闭。

My HTC WildFire does this when is about to be turned off

推荐答案

我用Google搜索机器人模糊背景，发现<一个href=\"http://www.stealthcopter.com/blog/2010/01/android-blurring-and-dimming-background-windows-from-dialogs/\"相对=nofollow>这个博客帖子。基本上是：

I googled for "android blur background" and found this blog post. Basically:

dialog = new AlertDialog.Builder(this). /*... setTitle and so on ...*/ ;

WindowManager.LayoutParams lp = dialog.getWindow().getAttributes();  
lp.dimAmount=0.0f;  // this sets the amount of darkening
dialog.getWindow().setAttributes(lp);  
dialog.getWindow().addFlags(WindowManager.LayoutParams.FLAG_BLUR_BEHIND);
