Inherited methods

From class


  
    java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.

`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long millis, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void`	`wait(long millis)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.

Public methods

buildTypeface

added in API level 26

Typeface buildTypeface (Context context, 
                CancellationSignal cancellationSignal, 
                FontInfo[] fonts)

Build a Typeface from an array of FontsContract.FontInfo Results that are marked as not ready will be skipped.

Parameters
`context`	`Context`: A `Context` that will be used to fetch the font contents. This value must never be `null`.
`cancellationSignal`	`CancellationSignal`: A signal to cancel the operation in progress, or null if none. If the operation is canceled, then `OperationCanceledException` will be thrown.
`fonts`	`FontInfo`: An array of `FontsContract.FontInfo` to be used to create a Typeface. This value must never be `null`.

Returns
`Typeface`	A Typeface object. Returns null if typeface creation fails.

fetchFonts

added in API level 26

FontsContract.FontFamilyResult fetchFonts (Context context, 
                CancellationSignal cancellationSignal, 
                FontRequest request)

Fetch fonts given a font request.

Parameters
`context`	`Context`: A `Context` to be used for fetching fonts. This value must never be `null`.
`cancellationSignal`	`CancellationSignal`: A signal to cancel the operation in progress, or null if none. If the operation is canceled, then `OperationCanceledException` will be thrown when the query is executed.
`request`	`FontRequest`: A `FontRequest` object that identifies the provider and query for the request. This value must never be `null`.

Returns
`FontsContract.FontFamilyResult`	`FontsContract.FontFamilyResult` This value will never be `null`.

Throws
`PackageManager.NameNotFoundException`	If requested package or authority was not found in system.

requestFonts

added in API level 26

void requestFonts (Context context, 
                FontRequest request, 
                Handler handler, 
                CancellationSignal cancellationSignal, 
                FontsContract.FontRequestCallback callback)

Create a typeface object given a font request. The font will be asynchronously fetched, therefore the result is delivered to the given callback. See FontRequest. Only one of the methods in callback will be invoked, depending on whether the request succeeds or fails. These calls will happen on the caller thread. Note that the result Typeface may be cached internally and the same instance will be returned the next time you call this method with the same request. If you want to bypass this cache, use fetchFonts(Context, CancellationSignal, FontRequest) and buildTypeface(Context, CancellationSignal, FontsContract.FontInfo[]) instead.

Parameters
`context`	`Context`: A context to be used for fetching from font provider. This value must never be `null`.
`request`	`FontRequest`: A `FontRequest` object that identifies the provider and query for the request. May not be null.
`handler`	`Handler`: A handler to be processed the font fetching. This value must never be `null`.
`cancellationSignal`	`CancellationSignal`: A signal to cancel the operation in progress, or null if none. If the operation is canceled, then `OperationCanceledException` will be thrown.
`callback`	`FontsContract.FontRequestCallback`: A callback that will be triggered when results are obtained. May not be null.
