public class MenuPopupHelper extends Object implements MenuHelper
  • Constructor Details

  • Method Details

    • setOnDismissListener

      public void setOnDismissListener(@Nullable PopupWindow.OnDismissListener listener)
    • setAnchorView

      public void setAnchorView(@NonNull View anchor)
      Sets the view to which the popup window is anchored.

      Changes take effect on the next call to show().

      Parameters:
      anchor - the view to which the popup window should be anchored
    • setForceShowIcon

      public void setForceShowIcon(boolean forceShowIcon)
      Sets whether the popup menu's adapter is forced to show icons in the menu item views.

      Changes take effect on the next call to show().

      This method should not be accessed directly outside the framework, please use PopupMenu.setForceShowIcon(boolean) instead.

      Parameters:
      forceShowIcon - true to force icons to be shown, or false for icons to be optionally shown
    • setGravity

      public void setGravity(int gravity)
      Sets the alignment of the popup window relative to the anchor view.

      Changes take effect on the next call to show().

      Parameters:
      gravity - alignment of the popup relative to the anchor
    • getGravity

      public int getGravity()
      Returns:
      alignment of the popup relative to the anchor
    • show

      public void show()
    • show

      public void show(int x, int y)
    • getPopup

      @NonNull public MenuPopup getPopup()
    • tryShow

      public boolean tryShow()
      Attempts to show the popup anchored to the view specified by setAnchorView(View).
      Returns:
      true if the popup was shown or was already showing prior to calling this method, false otherwise
    • tryShow

      public boolean tryShow(int x, int y)
      Shows the popup menu and makes a best-effort to anchor it to the specified (x,y) coordinate relative to the anchor view.

      Additionally, the popup's transition epicenter (see PopupWindow.setEpicenterBounds(Rect) will be centered on the specified coordinate, rather than using the bounds of the anchor view.

      If the popup's resolved gravity is Gravity.LEFT, this will display the popup with its top-left corner at (x,y) relative to the anchor view. If the resolved gravity is Gravity.RIGHT, the popup's top-right corner will be at (x,y).

      If the popup cannot be displayed fully on-screen, this method will attempt to scroll the anchor view's ancestors and/or offset the popup such that it may be displayed fully on-screen.

      Parameters:
      x - x coordinate relative to the anchor view
      y - y coordinate relative to the anchor view
      Returns:
      true if the popup was shown or was already showing prior to calling this method, false otherwise
    • dismiss

      public void dismiss()
      Dismisses the popup, if showing.
      Specified by:
      dismiss in interface MenuHelper
    • onDismiss

      protected void onDismiss()

      Note: Subclasses should call the super implementation last to ensure that any necessary tear down has occurred before the listener specified by setOnDismissListener(PopupWindow.OnDismissListener) is called.
