BitmapDrawable

public class BitmapDrawable
extends Drawable

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

A Drawable that wraps a bitmap and can be tiled, stretched, or aligned. You can create a BitmapDrawable from a file path, an input stream, through XML inflation, or from a Bitmap object.

It can be defined in an XML file with the <bitmap> element. For more information, see the guide to Drawable Resources.

Also see the Bitmap class, which handles the management and transformation of raw bitmap graphics, and should be used when drawing to a Canvas.

getGravity

Added in API level 1

int getGravity ()

Get the gravity used to position/stretch the bitmap within its bounds. See android.view.Gravity

Returns
`int`	the gravity applied to the bitmap

getIntrinsicHeight

Added in API level 1

int getIntrinsicHeight ()

Returns the drawable's intrinsic height.

Intrinsic height is the height at which the drawable would like to be laid out, including any inherent padding. If the drawable has no intrinsic height, such as a solid color, this method returns -1.

Returns
`int`	the intrinsic height, or -1 if no intrinsic height

getIntrinsicWidth

Added in API level 1

int getIntrinsicWidth ()

Returns the drawable's intrinsic width.

Intrinsic width is the width at which the drawable would like to be laid out, including any inherent padding. If the drawable has no intrinsic width, such as a solid color, this method returns -1.

Returns
`int`	the intrinsic width, or -1 if no intrinsic width

getOpacity

Added in API level 1

int getOpacity ()

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

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 resolveOpacity(int, 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 setAlpha(int) or setColorFilter(ColorFilter) methods. Some subclasses, such as BitmapDrawable, ColorDrawable, and GradientDrawable, do account for the value of setAlpha(int), but the general behavior is dependent upon the implementation of the subclass.

Returns
`int`	int The opacity class of the Drawable.

getOutline

Added in API level 21

void getOutline (Outline outline)

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.

Parameters
`outline`	`Outline`

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.

Returns
`boolean`	True if this drawable changes its appearance based on state, false otherwise.

mutate

Added in API level 3

Drawable mutate ()

A mutable BitmapDrawable still shares its Bitmap with any other Drawable that comes from the same resource.

Returns
`Drawable`	This drawable.

setAlpha

Added in API level 1

void setAlpha (int alpha)

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

Parameters
`alpha`	`int`

setAntiAlias

Added in API level 1

void setAntiAlias (boolean aa)

Enables or disables anti-aliasing for this drawable. Anti-aliasing affects the edges of the bitmap only so it applies only when the drawable is rotated.

Parameters
`aa`	`boolean`: True if the bitmap should be anti-aliased, false otherwise.

See also:

hasAntiAlias()

setAutoMirrored

Added in API level 19

void setAutoMirrored (boolean mirrored)

Set whether this Drawable is automatically mirrored when its layout direction is RTL (right-to left). See LayoutDirection.

Parameters
`mirrored`	`boolean`: Set to true if the Drawable should be mirrored, false if not.

setColorFilter

Added in API level 1

void setColorFilter (ColorFilter colorFilter)

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 tint.

Parameters
`colorFilter`	`ColorFilter`: The color filter to apply, or `null` to remove the existing color filter

setDither

Added in API level 1

void setDither (boolean dither)

This method is deprecated.
This property is ignored.

Set to true to have the drawable dither its colors when drawn to a device with fewer than 8-bits per color component.

Parameters
`dither`	`boolean`

setFilterBitmap

Added in API level 1

void setFilterBitmap (boolean filter)

Set to true to have the drawable filter its bitmaps with bilinear sampling when they are scaled or rotated.

This can improve appearance when bitmaps are rotated. If the drawable does not use bitmaps, this call is ignored.

Parameters
`filter`	`boolean`

setGravity

Added in API level 1

void setGravity (int gravity)

Set the gravity used to position/stretch the bitmap within its bounds. See android.view.Gravity

Parameters
`gravity`	`int`: the gravity

setMipMap

Added in API level 18

void setMipMap (boolean mipMap)

Enables or disables the mipmap hint for this drawable's bitmap. See setHasMipMap(boolean) for more information. If the bitmap is null calling this method has no effect.

Parameters
`mipMap`	`boolean`: True if the bitmap should use mipmaps, false otherwise.

hasMipMap()

setTargetDensity

Added in API level 4

void setTargetDensity (DisplayMetrics metrics)

Set the density scale at which this drawable will be rendered.

Parameters
`metrics`	`DisplayMetrics`: The DisplayMetrics indicating the density scale for this drawable.

See also:

setDensity(int)
getDensity()

setTargetDensity

Added in API level 4

void setTargetDensity (Canvas canvas)

Set the density scale at which this drawable will be rendered. This method assumes the drawable will be rendered at the same density as the specified canvas.

Parameters
`canvas`	`Canvas`: The Canvas from which the density scale must be obtained.

See also:

setDensity(int)
getDensity()

setTargetDensity

Added in API level 4

void setTargetDensity (int density)

Set the density at which this drawable will be rendered.

Parameters
`density`	`int`: The density scale for this drawable.

See also:

setDensity(int)
getDensity()

setTileModeX

Added in API level 1

void setTileModeX (Shader.TileMode mode)

Sets the repeat behavior of this drawable on the X axis. By default, the drawable does not repeat its bitmap. Using REPEAT or MIRROR the bitmap can be repeated (or tiled) if the bitmap is smaller than this drawable.

Related XML Attributes:

android:tileModeX

Parameters
`mode`	`Shader.TileMode`: The repeat mode for this drawable.

See also:

setTileModeXY

Added in API level 1

void setTileModeXY (Shader.TileMode xmode, 
                Shader.TileMode ymode)

Sets the repeat behavior of this drawable on both axis. By default, the drawable does not repeat its bitmap. Using REPEAT or MIRROR the bitmap can be repeated (or tiled) if the bitmap is smaller than this drawable.

Parameters
`xmode`	`Shader.TileMode`: The X repeat mode for this drawable.
`ymode`	`Shader.TileMode`: The Y repeat mode for this drawable.

See also:

setTileModeY

Added in API level 1

void setTileModeY (Shader.TileMode mode)

Sets the repeat behavior of this drawable on the Y axis. By default, the drawable does not repeat its bitmap. Using REPEAT or MIRROR the bitmap can be repeated (or tiled) if the bitmap is smaller than this drawable.

Related XML Attributes:

android:tileModeY

Parameters
`mode`	`Shader.TileMode`: The repeat mode for this drawable.

See also:

setTintList

Added in API level 21

void setTintList (ColorStateList tint)

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

A Drawable's drawing content will be blended together with its tint before it is drawn to the screen. This functions similarly to setColorFilter(int, PorterDuff.Mode).

Note: Setting a color filter via setColorFilter(ColorFilter) or setColorFilter(int, PorterDuff.Mode) overrides tint.

Parameters
`tint`	`ColorStateList`: Color state list to use for tinting this drawable, or `null` to clear the tint

setTintMode

Added in API level 21

void setTintMode (PorterDuff.Mode tintMode)

Specifies a tint blending mode for this drawable.

Defines how this drawable's tint color should be blended into the drawable before it is drawn to screen. Default tint mode is SRC_IN.

Note: Setting a color filter via setColorFilter(ColorFilter) or setColorFilter(int, PorterDuff.Mode) overrides tint.

Parameters
`tintMode`	`PorterDuff.Mode`: A Porter-Duff blending mode

Protected methods

onBoundsChange

Added in API level 1

void onBoundsChange (Rect bounds)

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

Parameters
`bounds`	`Rect`

onStateChange

Added in API level 1

boolean onStateChange (int[] stateSet)

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

Parameters
`stateSet`	`int`

Returns
`boolean`	Returns true if the state change has caused the appearance of the Drawable to change (that is, it needs to be drawn), else false if it looks the same and there is no need to redraw it since its last state.
