如何在Android中以像素为单位获取屏幕尺寸 - How to get screen dimensions as pixels in Android

问题：

I created some custom elements, and I want to programmatically place them to the upper right corner ( n pixels from the top edge and m pixels from the right edge). 我建立了一些自定义元素，我想以编程方式将它们放置在右上角（顶部边缘n像素，右侧边缘m像素）。 Therefore I need to get the screen width and screen height and then set position: 所以，我须要获取屏幕宽度和屏幕高度，而后设置位置：

int px = screenWidth - m;
int py = screenHeight - n;

How do I get screenWidth and screenHeight in the main Activity? 如何在主活动中获取screenWidth和screenHeight ？
