This ensures that tab selection events update the ViewPager and page changes update the selected tab. However, if you are using a ViewPager for horizontal paging between tabs, you can create tabs directly from your PagerAdapter’s getPageTitle() and then connect the two together using setupWithViewPager(). TabLayout.addTab(tabLayout.newTab().setText("Tab 1")) Tabs can be added programmatically: TabLayout tabLayout =. The Design library’s TabLayout implements both fixed tabs, where the view’s width is divided equally between all of the tabs, as well as scrollable tabs, where the tabs are not a uniform size and can scroll horizontally. Switching between different views in your app via tabs is not a new concept to material design and they are equally at home as a top level navigation pattern or for organizing different groupings of content within your app (say, different genres of music). You’ll note the use of a View as the first parameter to make() - Snackbar will attempt to find an appropriate parent of the Snackbar’s view to ensure that it is anchored to the bottom. setAction(R.string.snackbar_action, myOnClickListener) make(parentLayout, R.string.snackbar_text, Snackbar.LENGTH_LONG) However, you’ll find the API very familiar: Snackbar In addition, users can swipe them away before the timeout.īy including the ability to interact with the Snackbar through swiping it away or actions, these are considerably more powerful than toasts, another lightweight feedback mechanism. They automatically time out after the given time length by animating off the screen. Snackbars are shown on the bottom of the screen and contain text with an optional single action. Providing lightweight, quick feedback about an operation is a perfect opportunity to use a snackbar. As FloatingActionButton extends ImageView, you’ll use android:src or any of the methods such as setImageDrawable() to control the icon shown within the FloatingActionButton. In addition to the normal size floating action button, it also supports the mini size ( fabSize="mini") when visual continuity with other elements is critical. While an EditText alone will hide the hint text after the first character is typed, you can now wrap it in a TextInputLayout, causing the hint text to become a floating label above the EditText, ensuring that users never lose context in what they are entering. Floating labels for editing textĮven the humble EditText has room to improve in material design. This provides you with the MenuItem that was clicked, allowing you to handle selection events, changed the checked status, load new content, programmatically close the drawer, or any other actions you may want. You’ll get callbacks on selected items by setting a OnNavigationItemSelectedListener using setNavigationItemSelectedListener().

You can also use subheaders in your menu to separate groups of items: The checked item will appear highlighted in the navigation drawer, ensuring the user knows which navigation item is currently selected.

The simplest drawer menus will be a collection of checkable menu items: NavigationView takes care of the scrim protection of the status bar for you, ensuring that your NavigationView interacts with the status bar appropriately on API21+ devices. app:menu is the menu resource inflated for the navigation items (which can also be updated at runtime). You’ll note two attributes for NavigationView: app:headerLayout controls the (optional) layout used for the header. You use NavigationView as DrawerLayout’s drawer content view with a layout such as: NavigationView makes this easier by providing the framework you need for the navigation drawer as well as the ability to inflate your navigation items through a menu resource.

The navigation drawer can be an important focal point for identity and navigation within your app and consistency in the design here can make a considerable difference in how easy your app is to navigate, particularly for first time users. You’ll find a navigation drawer view, floating labels for editing text, a floating action button, snackbar, tabs, and a motion and scroll framework to tie them together.

With a little help from the new Android Design Support Library, we’re bringing a number of important material design components to all developers and to all Android 2.1 or higher devices. Our detailed spec is a great place to start to adopt material design, but we understand that it can be a challenge for developers, particularly ones concerned with backward compatibility. Android 5.0 Lollipop was one of the most significant Android releases ever, in no small part due to the introduction of material design, a new design language that refreshed the entire Android experience.
