ChildDrawable

Kotlin |Java

class ChildDrawable

kotlin.Any
↳	androidx.leanback.graphics.CompositeDrawable.ChildDrawable

Wrapper class holding a drawable object and BoundsRule to update drawable bounds when parent bound changes.

Summary

Public constructors
`<init>(drawable: Drawable!, parent: CompositeDrawable!)`

Public methods
BoundsRule!	`getBoundsRule()` Returns the instance of `BoundsRule`.
Drawable!	`getDrawable()` Returns the `Drawable`.
Unit	`recomputeBounds()` After changing the `BoundsRule`, user should call this function for the drawable to recalculate its bounds.

Properties
static Property<CompositeDrawable.ChildDrawable!, Int!>!	`BOTTOM_ABSOLUTE` Implementation of `Property` for overrideBottom attribute.
static Property<CompositeDrawable.ChildDrawable!, Float!>!	`BOTTOM_FRACTION` Implementation of `Property` for overwriting the bottom attribute of `BoundsRule` associated with this `ChildDrawable`.
static Property<CompositeDrawable.ChildDrawable!, Int!>!	`LEFT_ABSOLUTE` Implementation of `Property` for overrideLeft attribute.
static Property<CompositeDrawable.ChildDrawable!, Float!>!	`LEFT_FRACTION` Implementation of `Property` for overwriting the bottom attribute of `BoundsRule` associated with this `ChildDrawable`.
static Property<CompositeDrawable.ChildDrawable!, Int!>!	`RIGHT_ABSOLUTE` Implementation of `Property` for overrideRight attribute.
static Property<CompositeDrawable.ChildDrawable!, Float!>!	`RIGHT_FRACTION` Implementation of `Property` for overwriting the bottom attribute of `BoundsRule` associated with this `ChildDrawable`.
static Property<CompositeDrawable.ChildDrawable!, Int!>!	`TOP_ABSOLUTE` Implementation of `Property` for overrideTop attribute.
static Property<CompositeDrawable.ChildDrawable!, Float!>!	`TOP_FRACTION` Implementation of `Property` for overwriting the bottom attribute of `BoundsRule` associated with this `ChildDrawable`.

Public constructors

<init>

ChildDrawable(
    drawable: Drawable!, 
    parent: CompositeDrawable!)

Public methods

getBoundsRule

fun getBoundsRule(): BoundsRule!

Returns the instance of BoundsRule.

getDrawable

fun getDrawable(): Drawable!

Returns the Drawable.

recomputeBounds

fun recomputeBounds(): Unit

After changing the BoundsRule, user should call this function for the drawable to recalculate its bounds.

Properties

BOTTOM_ABSOLUTE

static val BOTTOM_ABSOLUTE: Property<CompositeDrawable.ChildDrawable!, Int!>!

Implementation of Property for overrideBottom attribute.

BOTTOM_FRACTION

static val BOTTOM_FRACTION: Property<CompositeDrawable.ChildDrawable!, Float!>!

Implementation of Property for overwriting the bottom attribute of BoundsRule associated with this ChildDrawable. This allows users to change the bounds rules as a percentage of parent size. This is preferable over BOTTOM_ABSOLUTE when the exact start/end position of scroll movement isn't available at compile time.

LEFT_ABSOLUTE

static val LEFT_ABSOLUTE: Property<CompositeDrawable.ChildDrawable!, Int!>!

Implementation of Property for overrideLeft attribute.

LEFT_FRACTION

static val LEFT_FRACTION: Property<CompositeDrawable.ChildDrawable!, Float!>!

Implementation of Property for overwriting the bottom attribute of BoundsRule associated with this ChildDrawable. This allows users to change the bounds rules as a percentage of parent size. This is preferable over LEFT_ABSOLUTE when the exact start/end position of scroll movement isn't available at compile time.

RIGHT_ABSOLUTE

static val RIGHT_ABSOLUTE: Property<CompositeDrawable.ChildDrawable!, Int!>!

Implementation of Property for overrideRight attribute.

RIGHT_FRACTION

static val RIGHT_FRACTION: Property<CompositeDrawable.ChildDrawable!, Float!>!

Implementation of Property for overwriting the bottom attribute of BoundsRule associated with this ChildDrawable. This allows users to change the bounds rules as a percentage of parent size. This is preferable over RIGHT_ABSOLUTE when the exact start/end position of scroll movement isn't available at compile time.

TOP_ABSOLUTE

static val TOP_ABSOLUTE: Property<CompositeDrawable.ChildDrawable!, Int!>!

Implementation of Property for overrideTop attribute.

TOP_FRACTION

static val TOP_FRACTION: Property<CompositeDrawable.ChildDrawable!, Float!>!

Implementation of Property for overwriting the bottom attribute of BoundsRule associated with this ChildDrawable. This allows users to change the bounds rules as a percentage of parent size. This is preferable over TOP_ABSOLUTE when the exact start/end position of scroll movement isn't available at compile time.
