Public methods

getColor

added in version 24.1.0
int getColor (Resources res, 
                int id, 
                Resources.Theme theme)

Returns a themed color integer associated with a particular resource ID. If the resource holds a complex ColorStateList, then the default color from the set is returned.

Prior to API level 23, the theme will not be applied and this method calls through to getColor(int).

Parameters
res Resources

id int: The desired resource identifier, as generated by the aapt tool. This integer encodes the package, type, and resource entry. The value 0 is an invalid identifier.
theme Resources.Theme: The theme used to style the color attributes, may be null.
Returns
int A single color value in the form 0xAARRGGBB.
Throws
Resources.NotFoundException Throws NotFoundException if the given ID does not exist.

getColorStateList

added in version 24.1.0
ColorStateList getColorStateList (Resources res, 
                int id, 
                Resources.Theme theme)

Returns a themed color state list associated with a particular resource ID. The resource may contain either a single raw color value or a complex ColorStateList holding multiple possible colors.

Prior to API level 23, the theme will not be applied and this method calls through to getColorStateList(int).

Parameters
res Resources

id int: The desired resource identifier of a ColorStateList, as generated by the aapt tool. This integer encodes the package, type, and resource entry. The value 0 is an invalid identifier.
theme Resources.Theme: The theme used to style the color attributes, may be null.
Returns
ColorStateList A themed ColorStateList object containing either a single solid color or multiple colors that can be selected based on a state.
Throws
Resources.NotFoundException Throws NotFoundException if the given ID does not exist.

getDrawable

added in version 24.1.0
Drawable getDrawable (Resources res, 
                int id, 
                Resources.Theme theme)

Return a drawable object associated with a particular resource ID and styled for the specified theme. Various types of objects will be returned depending on the underlying resource -- for example, a solid color, PNG image, scalable image, etc.

Prior to API level 21, the theme will not be applied and this method simply calls through to getDrawable(int).

Parameters
res Resources

id int: The desired resource identifier, as generated by the aapt tool. This integer encodes the package, type, and resource entry. The value 0 is an invalid identifier.
theme Resources.Theme: The theme used to style the drawable attributes, may be null.
Returns
Drawable Drawable An object that can be used to draw this resource.
Throws
Resources.NotFoundException Throws NotFoundException if the given ID does not exist.

getDrawableForDensity

added in version 24.1.0
Drawable getDrawableForDensity (Resources res, 
                int id, 
                int density, 
                Resources.Theme theme)

Return a drawable object associated with a particular resource ID for the given screen density in DPI and styled for the specified theme.

Prior to API level 15, the theme and density will not be applied and this method simply calls through to getDrawable(int).

Prior to API level 21, the theme will not be applied and this method calls through to Resources#getDrawableForDensity(int, int).

Parameters
res Resources

id int: The desired resource identifier, as generated by the aapt tool. This integer encodes the package, type, and resource entry. The value 0 is an invalid identifier.
density int: The desired screen density indicated by the resource as found in DisplayMetrics.
theme Resources.Theme: The theme used to style the drawable attributes, may be null.
Returns
Drawable Drawable An object that can be used to draw this resource.
Throws
Resources.NotFoundException Throws NotFoundException if the given ID does not exist.

getFont

added in version 26.1.0
Typeface getFont (Context context, 
                int id)

Returns a font Typeface associated with a particular resource ID.

This method will block the calling thread to retrieve the requested font, including if it is from a font provider. If you wish to not have this behavior, use getFont(Context, int, FontCallback, Handler) instead.

Prior to API level 23, font resources with more than one font in a family will only load the font closest to a regular weight typeface.

Parameters
context Context: A context to retrieve the Resources from.
id int: The desired resource identifier of a Typeface, as generated by the aapt tool. This integer encodes the package, type, and resource entry. The value 0 is an invalid identifier.
Returns
Typeface A font Typeface object.
Throws
Resources.NotFoundException Throws NotFoundException if the given ID does not exist.

getFont

added in version 27.1.0
void getFont (Context context, 
                int id, 
                ResourcesCompat.FontCallback fontCallback, 
                Handler handler)

Returns a font Typeface associated with a particular resource ID asynchronously.

Prior to API level 23, font resources with more than one font in a family will only load the font closest to a regular weight typeface.

Parameters
context Context: A context to retrieve the Resources from.
id int: The desired resource identifier of a Typeface, as generated by the aapt tool. This integer encodes the package, type, and resource entry. The value 0 is an invalid identifier.
fontCallback ResourcesCompat.FontCallback: A callback to receive async fetching of this font. The callback will be triggered on the UI thread.
handler Handler: A handler for the thread the callback should be called on. If null, the callback will be called on the UI thread.
Throws
Resources.NotFoundException Throws NotFoundException if the given ID does not exist.
