如何在Android中以像素爲單位獲取屏幕尺寸 - How to get screen dimensions as pixels in Android

問題：

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). 我建立了一些自定義元素，我想以編程方式將它們放置在右上角（頂部邊緣n像素，右側邊緣m像素）。 Therefore I need to get the screen width and screen height and then set position: 所以，我須要獲取屏幕寬度和屏幕高度，而後設置位置：

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

How do I get screenWidth and screenHeight in the main Activity? 如何在主活動中獲取screenWidth和screenHeight ？
