Added in API level 3

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.

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 WRAP_CONTENT, MATCH_PARENT, or 0 to use the absolute width.
heightSpec int: an explicit height measure spec mode, either WRAP_CONTENT, MATCH_PARENT, or 0 to use the absolute height.

public void showAsDropDown (View anchor, int xoff, int yoff, int gravity)

Added in API level 19

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

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.

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

See also:

public void showAsDropDown (View anchor)

Added in API level 1
