WearableActionDrawerView, WearableNavigationDrawerView

WearableActionDrawerView	Ease of use class for creating a Wearable action drawer.
WearableNavigationDrawerView	Ease of use class for creating a Wearable navigation drawer.

View that contains drawer content and a peeking view for use with WearableDrawerLayout.

This view provides the ability to set its main content as well as a view shown while peeking. Specifying the peek view is entirely optional; a default is used if none are set. However, the content must be provided.

There are two ways to specify the content and peek views: by invoking setter methods on the WearableDrawerView, or by specifying the app:drawerContent and app:peekView attributes. Examples:

 // From Java: drawerView.setDrawerContent(drawerContentView); drawerView.setPeekContent(peekContentView); <!-- From XML: --> <androidx.wear.widget.drawer.WearableDrawerView android:layout_width="match_parent" android:layout_height="match_parent" android:layout_gravity="bottom" android:background="@color/red" app:drawerContent="@+id/drawer_content" app:peekView="@+id/peek_view"> <FrameLayout android:id="@id/drawer_content" android:layout_width="match_parent" android:layout_height="match_parent" /> <LinearLayout android:id="@id/peek_view" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center_horizontal" android:orientation="horizontal"> <ImageView android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@android:drawable/ic_media_play" /> <ImageView android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@android:drawable/ic_media_pause" /> </LinearLayout> </androidx.wear.widget.drawer.WearableDrawerView>

Indicates that the drawer is currently being dragged by the user.

Value: ViewDragHelper.STATE_DRAGGING

STATE_SETTLING

static val STATE_SETTLING: Int

Public methods

addView

open fun addView(child: View!, index: Int, params: LayoutParams!): Unit

isLocked

open fun isLocked(): Boolean

Returns true if the position of the drawer cannot be modified by user interaction. Specifically, a drawer cannot be opened, closed, or automatically peeked by . However, it can be explicitly opened, closed, and peeked by the developer. A drawer may be considered locked if the drawer is locked open, locked closed, or is closed and isLockedWhenClosed returns true.

isAutoPeekEnabled

open fun isAutoPeekEnabled(): Boolean

Returns true if this drawer has auto-peeking enabled. This will always return false for a locked drawer.

setPeekContent

open fun setPeekContent(content: View!): Unit

Set the peek content view.

Parameters
`content`	View!: The view to show when the drawer peeks.

onPeekContainerClicked

open fun onPeekContainerClicked(v: View!): Unit

Called when anything within the peek container is clicked. However, if a custom peek view is supplied and it handles the click, then this may not be called. The default behavior is to open the drawer.

getController

open fun getController(): WearableDrawerController!

Returns the WearableDrawerController associated with this WearableDrawerView. This will only be valid after this View has been added to its parent.

onDrawerStateChanged

open fun onDrawerStateChanged(state: Int): Unit

Called when the drawer state changes. This is analogous to .

Parameters
`state`	Int: one of `STATE_DRAGGING`, `STATE_SETTLING`, or `STATE_IDLE`

isOpenOnlyAtTopEnabled

open fun isOpenOnlyAtTopEnabled(): Boolean

Returns whether this drawer may only be opened by the user when at the top of the scrolling content. If there is no scrolling content, then this has no effect. Defaults to false.

setIsAutoPeekEnabled

open fun setIsAutoPeekEnabled(canAutoPeek: Boolean): Unit

Sets whether or not the drawer can automatically adjust its peek state. Note that locked drawers will never auto-peek, but their isAutoPeekEnabled state will be maintained through a lock/unlock cycle.

isPeekOnScrollDownEnabled

open fun isPeekOnScrollDownEnabled(): Boolean

Gets whether or not this drawer should peek while scrolling down. This is currently only supported for bottom drawers. Defaults to false.

isLockedWhenClosed

open fun isLockedWhenClosed(): Boolean

Returns true if this drawer should be locked when the user cannot see it.

#isLocked

getDrawerContent

@Nullable open fun getDrawerContent(): View?

Returns the drawer content view.

setIsLocked

open fun setIsLocked(locked: Boolean): Unit

Sets whether or not the position of the drawer can be modified by user interaction.

#isLocked

isOpened

open fun isOpened(): Boolean

Returns true if the drawer is fully open.

onDrawerClosed

open fun onDrawerClosed(): Unit

Called when the drawer has settled in a completely closed state. This is analogous to .

setDrawerContent

open fun setDrawerContent(@Nullable content: View?): Unit

Set the drawer content view.

Parameters
`content`	View?: The view to show when the drawer is open, or `null` if it should not open.

Returns the current drawer state, which will be one of STATE_DRAGGING, , or STATE_IDLE

Sets whether or not this drawer should peek while scrolling down. This is currently only supported for bottom drawers. Defaults to false.

onDrawerOpened

open fun onDrawerOpened(): Unit

Called when the drawer has settled in a completely open state. The drawer is interactive at this point. This is analogous to .

isPeeking

open fun isPeeking(): Boolean

Returns whether the drawer is either peeking or the peek view is animating open.

setOpenOnlyAtTopEnabled

open fun setOpenOnlyAtTopEnabled(openOnlyAtTop: Boolean): Unit
