Android Material Design has its unique Material Theme, vector drawable, custom shadows, animations and widgets. It’s been over a year since the new development platform was launched by Google with the Lollipop version. t. A prominent feature of the Material Design based Android framework that every Android developer must know well is the navigation drawer.
It slides in from the left and has three primary aspects –
Vertical spacing- the spacing is 24dp for status bar it is 24dp, subtitle is 56dp, and content spacing is 8dp and subtitles and list items are 48dp.
Content- since the Nav drawer occupies the full length of the device screen at a resting elevation of 16dp, everything behind the drawer must be visible with a darkened scrim. A list item changes colour after being selected, and Google recommends that this is a primary colour. A touch ripple can be added to highlight the row of the selected item.
They have given the option to add a darker tint of the primary colour if the touch or ripple colour does not contrast perfectly. The dividers in the nav are full-bleed within the drawer and 8dp padding is to be added above and below each divider. Settings, Help, Feedback and another support content appears at the bottom of the list.
There are two types of Nav drawers – permanent and persistent, based on their application.
Permanent Nav Drawer: The permanent navigation drawers are pinned to the left edge and are always visible. The threshold for their pinning is calculated using three minimum values – Side nav width , Content padding
and Content width
Permanent Navigation Drawer types
There are three types of permanent navigation drawers and the structure and behaviour of the interface determine the type of drawer to use.
Persistent Nav Drawer
Persistent navigation drawer can be toggle opened and closed. It has the same surface elevation as content and opens and closes by default on selecting the menu icon. Since it is placed outside the page grid, when opened, it forces the page content to change a size and adapt a smaller viewpoint.
The Nav Drawers are an essential aspect of every application and Google has a comprehensive design that is easy to integrate and has an ergonomic presentation.
