It must be massive sufficient to be simply tappable, even on smaller screens, however not so massive that it dominates the visible hierarchy.

Android’s Materials Design pointers advocate a minimal contact goal measurement of 48dp (density-independent pixels) for interactive components, together with the 3-dot menu. This measurement ensures snug interplay, particularly for customers with motor impairments.Colour additionally performs a big function within the visibility and discoverability of the 3-dot menu icon. The icon’s coloration ought to distinction sufficiently with its background to make it simply discernible.

“`The `MenuInflater` makes use of this XML file to construct the menu. While you name `inflater.inflate(R.menu.my_menu, popup.getMenu());`, the `MenuInflater` reads the XML, creates the `MenuItem` objects, and provides them to your `PopupMenu`. This separation of structure and code is a cornerstone of fine Android design. The `android:id` attribute is essential; it is the way you establish the chosen menu merchandise in your click on listener.

The `android:title` attribute offers the textual content displayed within the menu.
