Drawable that shows a ripple effect in response to state changes. The anchoring position of the ripple for a given state may be specified by calling #setHotspot(float,float) with the corresponding state attribute identifier.
A touch feedback drawable may contain multiple child layers, including a special mask layer that is not drawn to the screen. A single layer may be set as the mask from XML by specifying its `android:id` value as `https://developer.android.com/reference/kotlin/android/R.id.html#mask:kotlin.Int`. At run time, a single layer may be set as the mask using `setId(..., android.R.id.mask)` or an existing mask layer may be replaced using `setDrawableByLayerId(android.R.id.mask, ...)`.
```kotlin
<!-- A red ripple masked against an opaque rectangle. -->
<ripple android:color="#ffff0000">
<item android:id="@android:id/mask"
android:drawable="@android:color/white" />
</ripple>
```
If a mask layer is set, the ripple effect will be masked against that layer before it is drawn over the composite of the remaining child layers.
If no mask layer is set, the ripple effect is masked against the composite of the child layers.
```kotlin
<!-- A green ripple drawn atop a black rectangle. -->
<ripple android:color="#ff00ff00">
<item android:drawable="@android:color/black" />
</ripple>
<!-- A blue ripple drawn atop a drawable resource. -->
<ripple android:color="#ff0000ff">
<item android:drawable="@drawable/my_drawable" />
</ripple>
```
If no child layers or mask is specified and the ripple is set as a View background, the ripple will be drawn atop the first available parent background within the View's hierarchy. In this case, the drawing region may extend outside of the Drawable bounds.
```kotlin
<!-- An unbounded red ripple. -->
<ripple android:color="#ffff0000" />
```

A return value of `-1` means there is no explicit padding set for this dimension. As a result, the value for this dimension returned by `https://developer.android.com/reference/kotlin/android/graphics/drawable/LayerDrawable#getPadding(android.graphics.Rect)` will be computed from the child layers according to the padding mode (see `https://developer.android.com/reference/kotlin/android/graphics/drawable/LayerDrawable#getPaddingMode()`.
`https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html` `https://developer.android.com/reference/kotlin/android/graphics/drawable/LayerDrawable#getStartPadding()()`
Returns the start padding in pixels.
A return value of `-1` means there is no explicit padding set for this dimension. As a result, the value for this dimension returned by `https://developer.android.com/reference/kotlin/android/graphics/drawable/LayerDrawable#getPadding(android.graphics.Rect)` will be computed from the child layers according to the padding mode (see `https://developer.android.com/reference/kotlin/android/graphics/drawable/LayerDrawable#getPaddingMode()`.

A Drawable can call this to schedule the next frame of its animation. An implementation can generally simply call `https://developer.android.com/reference/kotlin/android/os/Handler.html#postAtTime(java.lang.Runnable,%20kotlin.Any,%20kotlin.Long)` with the parameters (what, who, when) to perform the scheduling.
`https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-unit/index.html` `https://developer.android.com/reference/kotlin/android/graphics/drawable/LayerDrawable#setAlpha(kotlin.Int)(alpha: https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html)`
Specify an alpha value for the drawable. 0 means fully transparent, and 255 means fully opaque.
`https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-unit/index.html` `https://developer.android.com/reference/kotlin/android/graphics/drawable/LayerDrawable#setAutoMirrored(kotlin.Boolean)(mirrored: https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-boolean/index.html)`

Specify an optional color filter for the drawable.
If a Drawable has a ColorFilter, each output pixel of the Drawable's drawing contents will be modified by the color filter before it is blended onto the render target of a Canvas.
Pass `null` to remove any existing color filter.
**Note:** Setting a non-`null` color filter disables `https://developer.android.com/reference/kotlin/android/graphics/drawable/Drawable#setTintList(android.content.res.ColorStateList)`.

Sets the gravity used to position or stretch the specified layer within its container. Gravity is applied after any layer insets (see `https://developer.android.com/reference/kotlin/android/graphics/drawable/LayerDrawable#setLayerInset(kotlin.Int,%20kotlin.Int,%20kotlin.Int,%20kotlin.Int,%20kotlin.Int)`) or padding (see `https://developer.android.com/reference/kotlin/android/graphics/drawable/LayerDrawable#setPaddingMode(kotlin.Int)`).
If gravity is specified as `https://developer.android.com/reference/kotlin/android/view/Gravity.html#NO_GRAVITY:kotlin.Int`, the default behavior depends on whether an explicit width or height has been set (see `https://developer.android.com/reference/kotlin/android/graphics/drawable/LayerDrawable#setLayerSize(kotlin.Int,%20kotlin.Int,%20kotlin.Int)`), If a dimension is not set, gravity in that direction defaults to `https://developer.android.com/reference/kotlin/android/view/Gravity.html#FILL_HORIZONTAL:kotlin.Int` or `https://developer.android.com/reference/kotlin/android/view/Gravity.html#FILL_VERTICAL:kotlin.Int`; otherwise, gravity in that direction defaults to `https://developer.android.com/reference/kotlin/android/view/Gravity.html#LEFT:kotlin.Int` or `https://developer.android.com/reference/kotlin/android/view/Gravity.html#TOP:kotlin.Int`.

`https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-unit/index.html` `https://developer.android.com/reference/kotlin/android/graphics/drawable/LayerDrawable#setPadding(kotlin.Int,%20kotlin.Int,%20kotlin.Int,%20kotlin.Int)(left: https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html, top: https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html, right: https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html, bottom: https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html)`
Sets the absolute padding.
If padding in a dimension is specified as `-1`, the resolved padding will use the value computed according to the padding mode (see `https://developer.android.com/reference/kotlin/android/graphics/drawable/LayerDrawable#setPaddingMode(kotlin.Int)`).
Calling this method clears any relative padding values previously set using `https://developer.android.com/reference/kotlin/android/graphics/drawable/LayerDrawable#setPaddingRelative(kotlin.Int,%20kotlin.Int,%20kotlin.Int,%20kotlin.Int)`.

`https://developer.android.com/reference/kotlin/android/graphics/Region.html#?` `https://developer.android.com/reference/kotlin/android/graphics/drawable/Drawable#getTransparentRegion()()`
Returns a Region representing the part of the Drawable that is completely transparent. This can be used to perform drawing operations, identifying which parts of the target will not change when rendering the Drawable. The default implementation returns null, indicating no transparent region; subclasses can optionally override this to return an actual Region if they want to supply this optimization information, but it is not required that they do so.

Specify the level for the drawable. This allows a drawable to vary its imagery based on a continuous controller, for example to show progress or volume level.
If the new level you are supplying causes the appearance of the Drawable to change, then it is responsible for calling `https://developer.android.com/reference/kotlin/android/graphics/drawable/Drawable#invalidateSelf()` in order to have itself redrawn, *and* true will be returned from this function.
`https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-boolean/index.html` `https://developer.android.com/reference/kotlin/android/graphics/drawable/Drawable#setState(kotlin.IntArray)(stateSet: https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int-array/index.html)`
Specify a set of states for the drawable. These are use-case specific, so see the relevant documentation. As an example, the background for widgets like Button understand the following states: \[`https://developer.android.com/reference/kotlin/android/R.attr.html#state_focused:kotlin.Int`, `https://developer.android.com/reference/kotlin/android/R.attr.html#state_pressed:kotlin.Int`\].
If the new state you are supplying causes the appearance of the Drawable to change, then it is responsible for calling `https://developer.android.com/reference/kotlin/android/graphics/drawable/Drawable#invalidateSelf()` in order to have itself redrawn, *and* true will be returned from this function.
Note: The Drawable holds a reference on to stateSet until a new state array is given to it, so you must not modify this array during that time.
`https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-unit/index.html` `https://developer.android.com/reference/kotlin/android/graphics/drawable/Drawable#setTint(kotlin.Int)(tintColor: https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html)`
Specifies tint color for this drawable.
A Drawable's drawing content will be blended together with its tint before it is drawn to the screen. This functions similarly to `https://developer.android.com/reference/kotlin/android/graphics/drawable/Drawable#setColorFilter(kotlin.Int,%20android.graphics.PorterDuff.Mode)`.
To clear the tint, pass `null` to `https://developer.android.com/reference/kotlin/android/graphics/drawable/Drawable#setTintList(android.content.res.ColorStateList)`.
**Note:** Setting a color filter via `https://developer.android.com/reference/kotlin/android/graphics/drawable/Drawable#setColorFilter(android.graphics.ColorFilter)` or `https://developer.android.com/reference/kotlin/android/graphics/drawable/Drawable#setColorFilter(kotlin.Int,%20android.graphics.PorterDuff.Mode)` overrides tint.

```
open fun getDirtyBounds(): Rect
```
Return the drawable's dirty bounds Rect. Note: for efficiency, the returned object may be the same object stored in the drawable (though this is not guaranteed).

```
open fun getEffectColor(): ColorStateList
```
| Return ||
|---|---|
| `https://developer.android.com/reference/kotlin/android/content/res/ColorStateList.html#` | The ripple effect color as a color state list. This value cannot be `null`. |
### getHotspotBounds
Added in [API level 23](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)
```
open fun getHotspotBounds(outRect: Rect): Unit
```
Populates `outRect` with the hotspot bounds.
| Parameters ||
|---|---|
| `outRect` | [Rect](https://developer.android.com/reference/kotlin/android/graphics/Rect.html#): the rect to populate with the hotspot bounds. This value cannot be `null`. |
### getOpacity
Added in [API level 21](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)
```
open fun getOpacity(): Int
```
Return the opacity/transparency of this Drawable. The returned value is one of the abstract format constants in `https://developer.android.com/reference/kotlin/android/graphics/PixelFormat.html#`: `https://developer.android.com/reference/kotlin/android/graphics/PixelFormat.html#UNKNOWN:kotlin.Int`, `https://developer.android.com/reference/kotlin/android/graphics/PixelFormat.html#TRANSLUCENT:kotlin.Int`, `https://developer.android.com/reference/kotlin/android/graphics/PixelFormat.html#TRANSPARENT:kotlin.Int`, or `https://developer.android.com/reference/kotlin/android/graphics/PixelFormat.html#OPAQUE:kotlin.Int`.
An OPAQUE drawable is one that draws all all content within its bounds, completely covering anything behind the drawable. A TRANSPARENT drawable is one that draws nothing within its bounds, allowing everything behind it to show through. A TRANSLUCENT drawable is a drawable in any other state, where the drawable will draw some, but not all, of the content within its bounds and at least some content behind the drawable will be visible. If the visibility of the drawable's contents cannot be determined, the safest/best return value is TRANSLUCENT.
Generally a Drawable should be as conservative as possible with the value it returns. For example, if it contains multiple child drawables and only shows one of them at a time, if only one of the children is TRANSLUCENT and the others are OPAQUE then TRANSLUCENT should be returned. You can use the method `https://developer.android.com/reference/kotlin/android/graphics/drawable/Drawable#resolveOpacity(kotlin.Int,%20kotlin.Int)` to perform a standard reduction of two opacities to the appropriate single output.
Note that the returned value does not necessarily take into account a custom alpha or color filter that has been applied by the client through the `https://developer.android.com/reference/kotlin/android/graphics/drawable/Drawable#setAlpha(kotlin.Int)` or #setColorFilter methods. Some subclasses, such as `https://developer.android.com/reference/kotlin/android/graphics/drawable/BitmapDrawable`, `https://developer.android.com/reference/kotlin/android/graphics/drawable/ColorDrawable`, and `https://developer.android.com/reference/kotlin/android/graphics/drawable/GradientDrawable`, do account for the value of `https://developer.android.com/reference/kotlin/android/graphics/drawable/Drawable#setAlpha(kotlin.Int)`, but the general behavior is dependent upon the implementation of the subclass.
| Return ||
|---|---|
| `https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html` | int The opacity class of the Drawable. Value is one of the following: - `https://developer.android.com/reference/kotlin/android/graphics/PixelFormat.html#UNKNOWN:kotlin.Int` - `https://developer.android.com/reference/kotlin/android/graphics/PixelFormat.html#TRANSLUCENT:kotlin.Int` - `https://developer.android.com/reference/kotlin/android/graphics/PixelFormat.html#TRANSPARENT:kotlin.Int` - `https://developer.android.com/reference/kotlin/android/graphics/PixelFormat.html#OPAQUE:kotlin.Int` |

### hasFocusStateSpecified
Added in [API level 31](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)
```
open fun hasFocusStateSpecified(): Boolean
```
Indicates whether this drawable has at least one state spec explicitly specifying `https://developer.android.com/reference/kotlin/android/R.attr.html#state_focused:kotlin.Int`.
Note: A View uses a `https://developer.android.com/reference/kotlin/android/graphics/drawable/Drawable` instance as its background and it changes its appearance based on a state. On keyboard devices, it should specify its `https://developer.android.com/reference/kotlin/android/R.attr.html#state_focused:kotlin.Int` to make sure the user knows which view is holding the focus.
| Return ||
|---|---|
| `https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-boolean/index.html` | `true` if `https://developer.android.com/reference/kotlin/android/R.attr.html#state_focused:kotlin.Int` is specified for this drawable. |

### mutate
Added in [API level 21](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels)
```
open fun mutate(): Drawable
```
Make this drawable mutable. This operation cannot be reversed. A mutable drawable is guaranteed to not share its state with any other drawable. This is especially useful when you need to modify properties of drawables loaded from resources. By default, all drawables instances loaded from the same resource share a common state; if you modify the state of one instance, all the other instances will receive the same modification. Calling this method on a mutable Drawable will have no effect.
