android.view
windowmanager
應用程式用於與視窗管理器通訊的介面。
display
提供有關邏輯顯示的大小和密度的資訊。
android.util
displaymetrics
描述有關顯示的一般資訊的結構，例如其大小，密度和字型縮放。
要訪問displaymetrics成員，請初始化如下物件：
displaymetrics outmetrics = new displaymetrics()
;getwindowmanager()
.getdefaultdisplay()
.getrealmetrics
(outmetrics)
; displaymetrics displaymetrics =
getresources()
.getdisplaymetrics()
;
public class displayutil
