I have a spinner hidden in my application and I show it when a button is pressed ( performClick... ). What I want is, when the spinner is displayed, to dim the background so focus is on the spinner. Like when an alert dialog is shown where background gets dimmed. I didn't find anything in the Spinner Documentation. Any suggestions?

推荐答案

您可以将与微调和其他元素之间的白色或黑色背景的完整布局视图，当出现微调/消失/出动画的阿尔法。在出动画的结尾，你需要设置它的能见度 View.GONE 来禁止它来收集用户的点击。

You can place a full layout view with white or black background between the spinner and other elements and animate its alpha in/out when the spinner appears/disappears. At the end of "out" animation you need to set it's visibility to View.GONE to disallow it to gather user's clicks.
