    • setForceShowIcon

      public void setForceShowIcon(boolean forceShow)
      Specified by:
      setForceShowIcon in class MenuPopup

    • show

      public void show()
      Specified by:
      show in interface ShowableListMenu

    • dismiss

      public void dismiss()
      Specified by:
      dismiss in interface ShowableListMenu

    • onKey

      public boolean onKey(View v, int keyCode, KeyEvent event)
      Description copied from interface: View.OnKeyListener
      Called when a hardware key is dispatched to a view. This allows listeners to get a chance to respond before the target view.

      Key presses in software keyboards will generally NOT trigger this method, although some may elect to do so in some situations. Do not assume a software input method has to be key-based; even if it is, it may use key presses in a different way than you expect, so there is no way to reliably catch soft input key presses.

      Specified by:
      onKey in interface View.OnKeyListener
      Parameters:
      v - The view the key has been dispatched to.
      keyCode - The code for the physical key that was pressed
      event - The KeyEvent object containing full information about the event.
      Returns:
      True if the listener has consumed the event, false otherwise.

    • addMenu

      public void addMenu(MenuBuilder menu)
      Description copied from class: MenuPopup
      Adds the given menu to the popup, if it is capable of displaying submenus within itself. If menu is the first menu shown, it won't be displayed until show() is called. If the popup was already showing, adding a submenu via this method will cause that new submenu to be shown immediately (that is, if this MenuPopup implementation is capable of showing its own submenus).

      Parameters:
      menu - menu
