DrawerArrowDrawable

Kotlin |Java

open class DrawerArrowDrawable : Drawable

kotlin.Any
↳	android.graphics.drawable.Drawable
	↳	androidx.appcompat.graphics.drawable.DrawerArrowDrawable

A drawable that can draw a "Drawer hamburger" menu or an arrow and animate between them.

The progress between the two states is controlled via setProgress(float).

Constants

ARROW_DIRECTION_END

static val ARROW_DIRECTION_END: Int

Direction to make the arrow point to the end.

When used in a view with a RTL layout direction, this is the same as ARROW_DIRECTION_LEFT, otherwise it is the same as ARROW_DIRECTION_RIGHT.

Value: 3

ARROW_DIRECTION_LEFT

static val ARROW_DIRECTION_LEFT: Int

Direction to make the arrow point towards the left.

Value: 0

• #setDirection(int)
• #getDirection()

ARROW_DIRECTION_RIGHT

static val ARROW_DIRECTION_RIGHT: Int

Direction to make the arrow point towards the right.

Value: 1

• #setDirection(int)
• #getDirection()

ARROW_DIRECTION_START

static val ARROW_DIRECTION_START: Int

Direction to make the arrow point towards the start.

When used in a view with a RTL layout direction, this is the same as ARROW_DIRECTION_RIGHT, otherwise it is the same as ARROW_DIRECTION_LEFT.

Value: 2
