我写的自定义视图绘制一个圆。然后，我把它放在相对布局。此外，我把标准按钮出现，让他们重叠。而我看​​到的那个按钮是透明的。如何使它非透明？

I wrote custom View which draws a circle. Then I put it on relative layout. Also I put standard button there, so that they overlap. And I see that button is transparent. How to make it non transparent?

推荐答案

标准霍洛主题的按钮是部分透明。您可以创建一个新的按钮9.png图像中的按钮，使用或使用可绘制创建一个新的按钮。

The standard Holo themed button is partially transparent. You can either create a new button 9.png image to use in the button or create a new button by using drawable.
