在Android的，当你弹出一个对话框，在屏幕背后变暗。有什么办法来控制是什么样子？例如使其黯淡或多或少，或使用某种类型的模式？

In Android when you pop up a dialog the screen behind it dims. Is there any way to control what that looks like? For example making it dim more or less or using some kind of a pattern?

推荐答案

是的，确实如此。你可以控制它。

Yes, it is. You can control it.

在创建对话框：

WindowManager.LayoutParams lp = dialog.getWindow().getAttributes();  
lp.dimAmount=0.0f; // Dim level. 0.0 - no dim, 1.0 - completely opaque
dialog.getWindow().setAttributes(lp);

UPD ：你甚至可以添加模糊对话框后面：

Upd: you can even add blur behind the dialog:

dialog.getWindow().addFlags(WindowManager.LayoutParams.FLAG_BLUR_BEHIND);

Blurring因为API14 是德precated：

Blurring is deprecated since API14:

此常数德precated在API级别14   模糊不再支持。

This constant was deprecated in API level 14. Blurring is no longer supported.
