Class WindowManagerImpl

java.lang.Object
  android.view.WindowManagerImpl

All Implemented Interfaces:

ViewManager, WindowManager

public class WindowManagerImpl
extends Object
implements WindowManager

Low-level communication with the global system window manager. It implements the ViewManager interface, allowing you to add any View subclass as a top-level window on the screen. Additional window manager specific layout parameters are defined for control over how windows are displayed. It also implemens the WindowManager interface, allowing you to control the displays attached to the device.

Applications will not normally use WindowManager directly, instead relying on the higher-level facilities in Activity and Dialog.

Even for low-level window manager access, it is almost never correct to use this class. For example, Activity.getWindowManager() provides a ViewManager for adding windows that are associated with that activity -- the window manager will not normally allow you to add arbitrary windows that are not associated with an activity.
