Drawable.ConstantState

public static abstract class Drawable.ConstantState
extends Object

java.lang.Object
↳	android.graphics.drawable.Drawable.ConstantState

Known Direct Subclasses

DrawableContainer.DrawableContainerState

This abstract class is used by Drawables to store shared constant state and data between Drawables. BitmapDrawables created from the same resource will for instance share a unique bitmap stored in their ConstantState.

newDrawable(Resources) can be used as a factory to create new Drawable instances from this ConstantState.

Use getConstantState() to retrieve the ConstantState of a Drawable. Calling mutate() on a Drawable should typically create a new ConstantState for that Drawable.

Summary

Public constructors
`Drawable.ConstantState()`

Public methods
`boolean`	`canApplyTheme()` Return whether this constant state can have a theme applied.
`abstract int`	`getChangingConfigurations()` Return a bit mask of configuration changes that will impact this drawable (and thus require completely reloading it).
`Drawable`	`newDrawable(Resources res)` Creates a new Drawable instance from its constant state using the specified resources.
`abstract Drawable`	`newDrawable()` Creates a new Drawable instance from its constant state.
`Drawable`	`newDrawable(Resources res, Resources.Theme theme)` Creates a new Drawable instance from its constant state using the specified resources and theme.

Inherited methods

From class java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long millis, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void`	`wait(long millis)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void`	`wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.

Public methods

canApplyTheme

Added in API level 21

boolean canApplyTheme ()

Return whether this constant state can have a theme applied.

Returns
`boolean`

getChangingConfigurations

Added in API level 1

int getChangingConfigurations ()

Return a bit mask of configuration changes that will impact this drawable (and thus require completely reloading it).

Returns
`int`

newDrawable

Added in API level 5

Drawable newDrawable (Resources res)

Creates a new Drawable instance from its constant state using the specified resources. This method should be implemented for drawables that have density-dependent properties.

The default implementation for this method calls through to newDrawable().

Parameters
`res`	`Resources`: the resources of the context in which the drawable will be displayed

Returns
`Drawable`	a new drawable object based on this constant state

newDrawable

Added in API level 1

Drawable newDrawable ()

Creates a new Drawable instance from its constant state.

Note: Using this method means density-dependent properties, such as pixel dimensions or bitmap images, will not be updated to match the density of the target display. To ensure correct scaling, use newDrawable(Resources) instead to provide an appropriate Resources object.

Returns
`Drawable`	a new drawable object based on this constant state

newDrawable

Added in API level 21

Drawable newDrawable (Resources res, 
                Resources.Theme theme)

Creates a new Drawable instance from its constant state using the specified resources and theme. This method should be implemented for drawables that have theme-dependent properties.

The default implementation for this method calls through to newDrawable(Resources).

Parameters
`res`	`Resources`: the resources of the context in which the drawable will be displayed
`theme`	`Resources.Theme`: the theme of the context in which the drawable will be displayed

Returns
`Drawable`	a new drawable object based on this constant state
