Public fields
alpha
public static int alpha
Definitions of attributes to be exposed as public Alpha multiplier applied to the base color.
May be a floating point value, such as "1.2".
font
public static int font
The reference to the font file to be used. This should be a file in the res/font folder and should therefore have an R reference value. e.g. @font/myfont
May be a reference to another resource, in the form "@[+][package:]type/name" or a theme attribute in the form "?[package:]type/name".
fontProviderAuthority
public static int fontProviderAuthority
The authority of the Font Provider to be used for the request.
May be a string value, using '\\;' to escape characters such as '\\n' or '\\uxxxx' for a unicode character;
fontProviderCerts
public static int fontProviderCerts
The sets of hashes for the certificates the provider should be signed with. This is used to verify the identity of the provider, and is only required if the provider is not part of the system image. This value may point to one list or a list of lists, where each individual list represents one collection of signature hashes. Refer to your font provider's documentation for these values.
May be a reference to another resource, in the form "@[+][package:]type/name" or a theme attribute in the form "?[package:]type/name".
fontProviderFetchStrategy
public static int fontProviderFetchStrategy
The strategy to be used when fetching font data from a font provider in XML layouts. This attribute is ignored when the resource is loaded from code, as it is equivalent to the choice of API between getFont (blocking) and getFont (async).
Must be one of the following constant values.
| Constant | Value | Description |
|---|---|---|
| async | 1 | The async font fetch works as follows. First, check the local cache, then if the requested font is not cached, trigger a request the font and continue with layout inflation. Once the font fetch succeeds, the target text view will be refreshed with the downloaded font data. The fontProviderFetchTimeout will be ignored if async loading is specified. |
| blocking | 0 | The blocking font fetch works as follows. First, check the local cache, then if the requested font is not cached, request the font from the provider and wait until it is finished. You can change the length of the timeout by modifying fontProviderFetchTimeout. If the timeout happens, the default typeface will be used instead. |
fontProviderFetchTimeout
public static int fontProviderFetchTimeout
The length of the timeout during fetching.
May be an integer value, such as "100".
Must be one of the following constant values.
| Constant | Value | Description |
|---|---|---|
| forever | ffffffff | A special value for the timeout. In this case, the blocking font fetching will not timeout and wait until a reply is received from the font provider. |
fontProviderPackage
public static int fontProviderPackage
The package for the Font Provider to be used for the request. This is used to verify the identity of the provider.
May be a string value, using '\\;' to escape characters such as '\\n' or '\\uxxxx' for a unicode character;
fontProviderQuery
public static int fontProviderQuery
The query to be sent over to the provider. Refer to your font provider's documentation on the format of this string.
May be a string value, using '\\;' to escape characters such as '\\n' or '\\uxxxx' for a unicode character;
fontProviderSystemFontFamily
public static int fontProviderSystemFontFamily
May be a string value, using '\\;' to escape characters such as '\\n' or '\\uxxxx' for a unicode character;
fontStyle
public static int fontStyle
The style of the given font file. This will be used when the font is being loaded into the font stack and will override any style information in the font's header tables. If unspecified, the value in the font's header tables will be used.
Must be one of the following constant values.
| Constant | Value | Description |
|---|---|---|
| italic | 1 | |
| normal | 0 |
fontVariationSettings
public static int fontVariationSettings
Common name attributes. See comments of each attribute declaration in declare-styleable
May be a string value, using '\\;' to escape characters such as '\\n' or '\\uxxxx' for a unicode character;
fontWeight
public static int fontWeight
The weight of the given font file. This will be used when the font is being loaded into the font stack and will override any weight information in the font's header tables. Must be a positive number, a multiple of 100, and between 100 and 900, inclusive. The most common values are 400 for regular weight and 700 for bold weight. If unspecified, the value in the font's header tables will be used.
May be an integer value, such as "100".
lStar
public static int lStar
Perceptual luminance applied to the base color. From 0 to 100.
May be a floating point value, such as "1.2".
queryPatterns
public static int queryPatterns
Resource reference to the string array of query patterns for a custom capability.
May be a reference to another resource, in the form "@[+][package:]type/name" or a theme attribute in the form "?[package:]type/name".
shortcutMatchRequired
public static int shortcutMatchRequired
Indicates whether a parameter in a capability template can only contain a matched shortcut id and not an arbitrary string.
May be a boolean value, such as "true" or "false".
ttcIndex
public static int ttcIndex
The index of the font in the tcc font file. If the font file referenced is not in the tcc format, this attribute needs not be specified.
May be an integer value, such as "100".
