public
interface
WindowManager
implements
ViewManager
android.view.WindowManager |
The interface that apps use to talk to the window manager.
Use Context.getSystemService(Context.WINDOW_SERVICE)
to get one of these.
Each window manager instance is bound to a particular Display
.
To obtain a WindowManager
for a different display, use
createDisplayContext(Display)
to obtain a Context
for that
display, then use Context.getSystemService(Context.WINDOW_SERVICE)
to get the WindowManager.
The simplest way to show a window on another display is to create a
Presentation
. The presentation will automatically obtain a
WindowManager
and Context
for that display.

Display getDefaultDisplay ()
Returns the Display
upon which this WindowManager
instance
will create new windows.
Despite the name of this method, the display that is returned is not
necessarily the primary display of the system (see DEFAULT_DISPLAY
).
The returned display could instead be a secondary display that this
window manager instance is managing. Think of it as the display that
this WindowManager
instance uses by default.
To create windows on a different display, you need to obtain a
WindowManager
for that Display
. (See the WindowManager
class documentation for more information.)

void removeViewImmediate (View view)
Special variation of removeView(View)
that immediately invokes
the given view hierarchy's View.onDetachedFromWindow()
methods before returning. This is not
for normal applications; using it correctly requires great care.
Parameters | |

view |
View :
The view to be removed.
