This lesson provides information about creating attractive, custom UIs, including custom notifications for your watch apps.
Note: We recommend using Android Studio for Wear OS development, as it provides project setup, library inclusion, and packaging conveniences. This training assumes you are using Android Studio.
The Jetpack Wear Library (androidx.wear), which is in the Google Repository in the Android SDK, provides classes that help you implement UI patterns and create layouts that work on round, rectangle, and square Wear OS devices.
Note that the following classes in the Wear support library are deprecated in Wear 2.0:
- ActionChooserView. Use the AlertDialog class instead.
- CrossfadeDrawable. Use the AnimationSet class instead.
- DismissOverlayView. Long pressing to dismiss an app is no longer suggested for immersive activities (such as Google Maps).
- GridViewPager. To implement a vertical paging pattern, consider using the PagerSnapHelper and a RecyclerView instead.
- ProgressSpinner. Use the ProgressBar class instead.
- WatchViewStub and WearableFrameLayout. Provide alternative resources for specific device configurations as described in the Providing Resources guide.
-
WearableListView. Use the following classes
instead:
- For centering and snapping your list items, use the
WearableRecyclerViewclass supported by aSnapHelperor aLinearSnapHelperclass. - For scaling and otherwise modifying the list items based on
their location on the screen, use the
WearableLinearLayoutManager.LayoutCallbackclass.
