Get method documentation [Android Documentation]

Indicates whether the popup window will be informed of touch events outside of its window.

Set method documentation [Android Documentation]

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 PopupWindow.Update methods.
