Typeface.Builder

Kotlin |Java

public static final class Typeface.Builder
extends Object

java.lang.Object
↳	android.graphics.Typeface.Builder

A builder class for creating new Typeface instance.

Examples, 1) Create Typeface from ttf file.

 
 Typeface.Builder builder = new Typeface.Builder("your_font_file.ttf");
 Typeface typeface = builder.build();

2) Create Typeface from ttc file in assets directory.

 
 Typeface.Builder builder = new Typeface.Builder(getAssets(), "your_font_file.ttc");
 builder.setTtcIndex(2);  // Set index of font collection.
 Typeface typeface = builder.build();

3) Create Typeface with variation settings.

 
 Typeface.Builder builder = new Typeface.Builder("your_font_file.ttf");
 builder.setFontVariationSettings("'wght' 700, 'slnt' 20, 'ital' 1");
 builder.setWeight(700);  // Tell the system that this is a bold font.
 builder.setItalic(true);  // Tell the system that this is an italic style font.
 Typeface typeface = builder.build();

Public constructors

Builder

Added in API level 26

public Builder (File path)

Constructs a builder with a file path.

Parameters
`path`	`File`: The file object refers to the font file. This value cannot be `null`.

Builder

Added in API level 26

public Builder (FileDescriptor fd)

Constructs a builder with a file descriptor. Caller is responsible for closing the passed file descriptor after build() is called.

Parameters
`fd`	`FileDescriptor`: The file descriptor. The passed fd must be mmap-able. This value cannot be `null`.

Builder

Added in API level 26

public Builder (String path)

Constructs a builder with a file path.

Parameters
`path`	`String`: The full path to the font file. This value cannot be `null`.

Builder

Added in API level 26

public Builder (AssetManager assetManager, 
                String path)

Constructs a builder from an asset manager and a file path in an asset directory.

Parameters
`assetManager`	`AssetManager`: The application's asset manager This value cannot be `null`.
`path`	`String`: The file name of the font data in the asset directory This value cannot be `null`.

Public methods

build

Added in API level 26

public Typeface build ()

Generates new Typeface from specified configuration.

Returns
`Typeface`	Newly created Typeface. May return null if some parameters are invalid.

setFallback

Added in API level 26

public Typeface.Builder setFallback (String familyName)

Sets a fallback family name. By specifying a fallback family name, a fallback Typeface will be returned if the build() method fails to create a Typeface from the provided font. The fallback family will be resolved with the provided weight and italic information specified by setWeight(int) and setItalic(boolean). If setWeight(int) is not called, the fallback family keeps the default weight. Similarly, if setItalic(boolean) is not called, the fallback family keeps the default italic information. For example, calling builder.setFallback("sans-serif-light") is equivalent to calling builder.setFallback("sans-serif").setWeight(300) in terms of fallback. The default weight and italic information are overridden by calling setWeight(int) and setItalic(boolean). For example, if a Typeface is constructed using builder.setFallback("sans-serif-light").setWeight(700), the fallback text will render as sans serif bold.

Parameters
`familyName`	`String`: A family name to be used for fallback if the provided font can not be used. By passing `null`, build() returns `null`. If `setFallback(String)` is not called on the builder, `null` is assumed.

Returns
`Typeface.Builder`

setFontVariationSettings

Added in API level 26

public Typeface.Builder setFontVariationSettings (String variationSettings)

Sets a font variation settings.

Parameters
`variationSettings`	`String`: See `TextView.setFontVariationSettings(String)`. This value may be `null`.

Returns
`Typeface.Builder`

Throws
`IllegalArgumentException`	If given string is not a valid font variation settings format.

setFontVariationSettings

Added in API level 26

public Typeface.Builder setFontVariationSettings (FontVariationAxis[] axes)

Sets a font variation settings.

Parameters
`axes`	`FontVariationAxis`: An array of font variation axis tag-value pairs. This value may be `null`.

Returns
`Typeface.Builder`

setItalic

Added in API level 26

public Typeface.Builder setItalic (boolean italic)

Sets italic information of the font. Tells the system the style of the given font. If not provided, the system will resolve the style by reading font tables.

Returns
`Typeface.Builder`

setWeight

Added in API level 26

public Typeface.Builder setWeight (int weight)

Sets weight of the font. Tells the system the weight of the given font. If not provided, the system will resolve the weight value by reading font tables.
