class
BadgeDrawable
extends Drawable
java.lang.Object | ||
↳ | android.graphics.drawable.Drawable | |
↳ | com.google.android.material.badge.BadgeDrawable |
BadgeDrawable
contains all the layout and draw logic for a badge.
You can use BadgeDrawable
to display dynamic information such as a number of pending
requests in a BottomNavigationView
. To
create an instance of BadgeDrawable
, use create(Context)
or createFromResource(Context, int)
. How to add and display a BadgeDrawable
on top of its
anchor view depends on the API level:
For API 18+ (APIs supported by ViewOverlay
)
- Add
BadgeDrawable
as aViewOverlay
to the desired anchor view using BadgeUtils#attachBadgeDrawable(BadgeDrawable, View, FrameLayout) (This helper class is currently experimental). - Update the
BadgeDrawable BadgeDrawable's
coordinates (center and bounds) based on its anchor view usingupdateBadgeCoordinates(View, FrameLayout)
.
BadgeDrawable badgeDrawable = BadgeDrawable.create(context); badgeDrawable.setVisible(true); BadgeUtils.attachBadgeDrawable(badgeDrawable, anchor);
For Pre API-18
- Set
BadgeDrawable
as the foreground of the anchor view'sFrameLayout
ancestor usingBadgeUtils.attachBadgeDrawable(BadgeDrawable, View, FrameLayout)
(This helper class is currently experimental). - Update the
BadgeDrawable BadgeDrawable's
coordinates (center and bounds) based on its anchor view (relative to itsFrameLayout
ancestor's coordinate space), usingupdateBadgeCoordinates(View, FrameLayout)
.
BadgeDrawable
will dynamically create and wrap the anchor view in a FrameLayout
, then insert the FrameLayout
into the anchor view original position in the
view hierarchy. Same syntax as API 18+
BadgeDrawable badgeDrawable = BadgeDrawable.create(context); badgeDrawable.setVisible(true); BadgeUtils.attachBadgeDrawable(badgeDrawable, anchor);
BadgeDrawable
to modify your view hierarchy, you can specify
a FrameLayout
to display the badge instead.
BadgeDrawable badgeDrawable = BadgeDrawable.create(context); BadgeUtils.attachBadgeDrawable(badgeDrawable, anchor, anchorFrameLayoutParent);
By default, BadgeDrawable
is aligned to the top and end edges of its anchor view (with
some offsets). Call setBadgeGravity(int)
to change it to TOP_START
, the other
supported mode. To adjust the badge's offsets w.r.t. the anchor's center, use setHorizontalOffset(int)
, setVerticalOffset(int)
Note: This is still under development and may not support the full range of customization Material Android components generally support (e.g. themed attributes).
For more information, see the component developer guidance and design guidelines.

updateBadgeCoordinates
public void updateBadgeCoordinates (View anchorView, ViewGroup customBadgeParent)
This method is deprecated.
use updateBadgeCoordinates(View, FrameLayout)
instead.
Calculates and updates this badge's center coordinates based on its anchor's bounds. Internally
also updates this BadgeDrawable BadgeDrawable's
bounds, because they are dependent on
the center coordinates. For pre API-18, coordinates will be calculated relative to customBadgeParent
because the BadgeDrawable
will be set as the parent's foreground.
Parameters | |
---|---|
anchorView |
View : This badge's anchor. |
customBadgeParent |
ViewGroup : An optional parent view that will set this BadgeDrawable as
its foreground. |
updateBadgeCoordinates
public void updateBadgeCoordinates (View anchorView, FrameLayout customBadgeParent)
Calculates and updates this badge's center coordinates based on its anchor's bounds. Internally
also updates this BadgeDrawable BadgeDrawable's
bounds, because they are dependent on
the center coordinates.
For pre API-18, if no customBadgeParent
is specified, optionally wrap the anchor in
a FrameLayout
(if it's not done already) that will be inserted into the anchor's view
hierarchy and calculate the badge's coordinates the parent FrameLayout
