PopupWindow
public
class
PopupWindow
extends Object
java.lang.Object | |
↳ | android.widget.PopupWindow |
This class represents a popup window that can be used to display an arbitrary view. The popup window is a floating container that appears on top of the current activity.
Animation
On all versions of Android, popup window enter and exit animations may be
specified by calling setAnimationStyle(int)
and passing the
resource ID for an animation style that defines windowEnterAnimation
and windowExitAnimation
. For example, passing
R.style.Animation_Dialog
will give a scale and alpha
animation.
A window animation style may also be specified in the popup window's style
XML via the popupAnimationStyle
attribute.
Starting with API 23, more complex popup window enter and exit transitions
may be specified by calling either setEnterTransition(android.transition.Transition)
or setExitTransition(android.transition.Transition)
and passing a Transition
.
Popup enter and exit transitions may also be specified in the popup window's
style XML via the popupEnterTransition
and popupExitTransition
attributes, respectively.

public void setIsLaidOutInScreen (boolean enabled)
Allows the popup window to force the flag
WindowManager.LayoutParams#FLAG_LAYOUT_IN_SCREEN
, overriding default behavior.
This will cause the popup to be positioned in absolute screen coordinates.
Parameters | |
---|---|
enabled |
boolean : true if the popup should always be positioned in screen coordinates |

setOnDismissListener
public void setOnDismissListener (PopupWindow.OnDismissListener onDismissListener)
Sets the listener to be called when the window is dismissed.
Parameters | |
---|---|
onDismissListener |
PopupWindow.OnDismissListener : The listener. |
setOutsideTouchable
public void setOutsideTouchable (boolean touchable)
Controls whether the pop-up will be informed of touch events outside of its window. This only makes sense for pop-ups that are touchable but not focusable, which means touches outside of the window will be delivered to the window behind. The default is false.
If the popup is showing, calling this method will take effect only
the next time the popup is shown or through a manual call to one of
the update()
methods.
Parameters | |
---|---|
touchable |
boolean : true if the popup should receive outside
touch events, false otherwise |
See also:
setOverlapAnchor
public void setOverlapAnchor (boolean overlapAnchor)
Sets whether the popup window should overlap its anchor view when displayed as a drop-down.
If the popup is showing, calling this method will take effect only the next time the popup is shown.
Parameters | |
---|---|
overlapAnchor |
boolean : Whether the popup should overlap its anchor. |
See also:
setSoftInputMode
public void setSoftInputMode (int mode)
Sets the operating mode for the soft input area.
setSplitTouchEnabled
public void setSplitTouchEnabled (boolean enabled)
Allows the popup window to split touches across other windows that also support split touch. When this flag is false, the first pointer that goes down determines the window to which all subsequent touches go until all pointers go up. When this flag is true, each pointer (not necessarily the first) that goes down determines the window to which all subsequent touches of that pointer will go until that pointer goes up thereby enabling touches with multiple pointers to be split across multiple windows.
Parameters | |
---|---|
enabled |
boolean : true if the split touches should be enabled, false otherwise |
See also:
setTouchInterceptor
public void setTouchInterceptor (View.OnTouchListener l)
Set a callback for all touch events being dispatched to the popup window.
Parameters | |
---|---|
l |
View.OnTouchListener |
setTouchModal
public void setTouchModal (boolean touchModal)
Set whether this window is touch modal or if outside touches will be sent to other windows behind it.
If the popup is showing, calling this method will take effect only
the next time the popup is shown or through a manual call to one of
the update()
methods.
Parameters | |
---|---|
touchModal |
boolean : true to sent all outside touches to this window,
false to other windows behind it |
See also:
setTouchable
public void setTouchable (boolean touchable)
Changes the touchability of the popup window. When touchable, the window will receive touch events, otherwise touch events will go to the window below it. By default the window is touchable.
If the popup is showing, calling this method will take effect only
the next time the popup is shown or through a manual call to one of
the update()
methods.
Parameters | |
---|---|
touchable |
boolean : true if the popup should receive touch events, false otherwise |
See also:
setWidth
public void setWidth (int width)
Sets the popup's requested width. May be a layout constant such as
LayoutParams#WRAP_CONTENT
or LayoutParams#MATCH_PARENT
.
The actual size of the popup may depend on other factors such as clipping and window layout.
If the popup is showing, calling this method will take effect the next time the popup is shown.
Parameters | |
---|---|
width |
int : the popup width in pixels or a layout constant |
See also:
setWindowLayoutMode
public void setWindowLayoutMode (int widthSpec, int heightSpec)
This method was deprecated
in API level 23.
Use setWidth(int)
and setHeight(int)
.
Change the width and height measure specs that are given to the
window manager by the popup. By default these are 0, meaning that
the current width or height is requested as an explicit size from
the window manager. You can supply
ViewGroup.LayoutParams#WRAP_CONTENT
or
ViewGroup.LayoutParams#MATCH_PARENT
to have that measure
spec supplied instead, replacing the absolute width and height that
has been set in the popup.
If the popup is showing, calling this method will take effect only the next time the popup is shown.
Parameters | |
---|---|
widthSpec |
int : an explicit width measure spec mode, either
ViewGroup.LayoutParams#WRAP_CONTENT ,
ViewGroup.LayoutParams#MATCH_PARENT , or 0 to use the absolute
width. |
heightSpec |
int : an explicit height measure spec mode, either
ViewGroup.LayoutParams#WRAP_CONTENT ,
ViewGroup.LayoutParams#MATCH_PARENT , or 0 to use the absolute
height. |
setWindowLayoutType
public void setWindowLayoutType (int layoutType)
Set the layout type for this window.
See WindowManager.LayoutParams#type
for possible values.
Parameters | |
---|---|
layoutType |
int : Layout type for this window. |

showAsDropDown
public void showAsDropDown (View anchor)
Display the content view in a popup window anchored to the bottom-left corner of the anchor view. If there is not enough room on screen to show the popup in its entirety, this method tries to find a parent scroll view to scroll. If no parent scroll view can be scrolled, the bottom-left corner of the popup is pinned at the top left corner of the anchor view.
Parameters | |
---|---|
anchor |
View : the view on which to pin the popup window |
See also:
showAsDropDown
public void showAsDropDown (View anchor, int xoff, int yoff, int gravity)
Displays the content view in a popup window anchored to the corner of another view. The window is positioned according to the specified gravity and offset by the specified x and y coordinates.
If there is not enough room on screen to show the popup in its entirety, this method tries to find a parent scroll view to scroll. If no parent view can be scrolled, the specified vertical gravity will be ignored and the popup will anchor itself such that it is visible.
If the view later scrolls to move anchor
to a different
location, the popup will be moved correspondingly.
Parameters | |
---|---|
anchor |
View : the view on which to pin the popup window |
xoff |
int : A horizontal offset from the anchor in pixels |
yoff |
int : A vertical offset from the anchor in pixels |
gravity |
int : Alignment of the popup relative to the anchor |

a gravity of Gravity.NO_GRAVITY
is similar to specifying
Gravity.LEFT | Gravity.TOP
.
