WearableDrawerLayout

open class WearableDrawerLayout : FrameLayout, OnLayoutChangeListener, NestedScrollingParent, FlingListener

Top-level container that allows interactive drawers to be pulled from the top and bottom edge of the window. For WearableDrawerLayout to work properly, scrolling children must send nested scrolling events. Views that implement androidx.core.view.NestedScrollingChild do this by default. To enable nested scrolling on frameworks views like , set android:nestedScrollingEnabled="true" on the view in the layout file, or call View#setNestedScrollingEnabled in code. This includes the main content in a WearableDrawerLayout, as well as the content inside of the drawers.

To use WearableDrawerLayout with WearableActionDrawerView or , place either drawer in a WearableDrawerLayout.

 <androidx.wear.widget.drawer.WearableDrawerLayout [...]> <FrameLayout android:id=”@+id/content” /> <androidx.wear.widget.drawer.WearableNavigationDrawerView android:layout_width=”match_parent” android:layout_height=”match_parent” /> <androidx.wear.widget.drawer.WearableActionDrawerView android:layout_width=”match_parent” android:layout_height=”match_parent” /> </androidx.wear.widget.drawer.WearableDrawerLayout>

To use custom content in a drawer, place WearableDrawerView in a WearableDrawerLayout and specify the layout_gravity to pick the drawer location (the following example is for a top drawer). Note: You must either call WearableDrawerView#setDrawerContent and pass in your drawer content view, or specify it in the app:drawerContent XML attribute.

 <androidx.wear.widget.drawer.WearableDrawerLayout [...]> <FrameLayout android:id=”@+id/content” android:layout_width=”match_parent” android:layout_height=”match_parent” /> <androidx.wear.widget.drawer.WearableDrawerView android:layout_width=”match_parent” android:layout_height=”match_parent” android:layout_gravity=”top” app:drawerContent="@+id/top_drawer_content" > <FrameLayout android:id=”@id/top_drawer_content” android:layout_width=”match_parent” android:layout_height=”match_parent” /> </androidx.wear.widget.drawer.WearableDrawerView> </androidx.wear.widget.drawer.WearableDrawerLayout>
