WearableDrawerLayout

public class WearableDrawerLayout
extends FrameLayout implements View.OnLayoutChangeListener, NestedScrollingParent

java.lang.Object
   ↳ android.view.View
     ↳ android.view.ViewGroup
       ↳ android.widget.FrameLayout
         ↳ androidx.wear.widget.drawer.WearableDrawerLayout


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 NestedScrollingChild do this by default. To enable nested scrolling on frameworks views like ListView, set android:nestedScrollingEnabled="true" on the view in the layout file, or call View.setNestedScrollingEnabled(boolean) 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 WearableNavigationDrawerView, 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(View) 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>
