InsetDrawable

Applies the specified theme to this Drawable and its children.

Draw in its bounds (set via setBounds) respecting optional effects such as alpha (set via setAlpha) and color filter (set via setColorFilter).

Gets the current alpha value for the drawable. 0 means fully transparent, 255 means fully opaque. This method is implemented by Drawable subclasses and the value returned is specific to how that class treats alpha. The default return value is 255 if the class does not override this method to return a value specific to its use of alpha.

Return a mask of the configuration parameters for which this drawable may change, requiring that it be re-created. The default implementation returns whatever was provided through setChangingConfigurations(int) or 0 by default. Subclasses may extend this to or in the changing configurations of any other drawables they hold.

Return a Drawable.ConstantState instance that holds the shared state of this Drawable.

Returns the drawable wrapped by this InsetDrawable. May be null.

Return the intrinsic height of the underlying drawable object. Returns -1 if it has no intrinsic height, such as with a solid color.

Return the intrinsic width of the underlying drawable object. Returns -1 if it has no intrinsic width, such as with a solid color.

Return the opacity/transparency of this Drawable. The returned value is one of the abstract format constants in PixelFormat: UNKNOWN, TRANSLUCENT, TRANSPARENT, or OPAQUE.

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 resolveOpacity(int, int) to perform a standard reduction of two opacities to the appropriate single output.

Note that the returned value does not take into account a custom alpha or color filter that has been applied by the client through the setAlpha(int) or setColorFilter(ColorFilter) methods.

Called to get the drawable to populate the Outline that defines its drawing area.

This method is called by the default ViewOutlineProvider to define the outline of the View.

The default behavior defines the outline to be the bounding rectangle of 0 alpha. Subclasses that wish to convey a different shape or alpha value must override this method.

Return in padding the insets suggested by this Drawable for placing content inside the drawable's bounds. Positive values move toward the center of the Drawable (set Rect.inset).

Inflate this Drawable from an XML resource optionally styled by a theme.

Called when the drawable needs to be redrawn. A view at this point should invalidate itself (or at least the part of itself where the drawable appears).

Indicates whether this drawable will change its appearance based on state. Clients can use this to determine whether it is necessary to calculate their state and call setState.

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.

A Drawable can call this to schedule the next frame of its animation. An implementation can generally simply call postAtTime(Runnable, Object, long) with the parameters (what, who, when) to perform the scheduling.

Specify an alpha value for the drawable. 0 means fully transparent, and 255 means fully opaque.

Specify an optional color filter for the drawable. Pass null to remove any existing color filter.

Specifies the hotspot's location within the drawable.

Sets the bounds to which the hotspot is constrained, if they should be different from the drawable bounds.

Specifies a tint for this drawable as a color state list.

Setting a color filter via setColorFilter(ColorFilter) overrides tint.

Specifies a tint blending mode for this drawable.

Setting a color filter via setColorFilter(ColorFilter) overrides tint.

Set whether this Drawable is visible. This generally does not impact the Drawable's behavior, but is a hint that can be used by some Drawables, for example, to decide whether run animations.

A Drawable can call this to unschedule an action previously scheduled with scheduleDrawable(Drawable, Runnable, long). An implementation can generally simply call removeCallbacks(Runnable, Object) with the parameters (what, who) to unschedule the drawable.

Override this in your subclass to change appearance if you vary based on the bounds.

Override this in your subclass to change appearance if you vary based on level.

Override this in your subclass to change appearance if you recognize the specified state.
