public class Typeface
extends Object
java.lang.Object | |
↳ | android.graphics.Typeface |
The Typeface class specifies the typeface and intrinsic style of a font. This is used in the paint, along with optionally Paint settings like textSize, textSkewX, textScaleX to specify how text appears when drawn (and measured).

Typeface DEFAULT_BOLD
The default BOLD typeface object. Note: this may be not actually be bold, depending on what fonts are installed. Call getStyle() to know for sure.
Typeface MONOSPACE
The NORMAL style of the default monospace typeface.
Typeface SANS_SERIF
The NORMAL style of the default sans serif typeface.
Typeface create (Typeface family, int style)
Create a typeface object that best matches the specified existing typeface and the specified Style. Use this call if you want to pick a new style from the same family of an existing typeface object. If family is null, this selects from the default font's family.
Parameters | |
---|---|
family |
Typeface : May be null. The name of the existing type face. |
style |
int : The style (normal, bold, italic) of the typeface. e.g. NORMAL, BOLD, ITALIC, BOLD_ITALIC |
Returns | |
---|---|
Typeface |
The best matching typeface. |
Typeface create (String familyName, int style)
Create a typeface object given a family name, and option style information. If null is passed for the name, then the "default" font will be chosen. The resulting typeface object can be queried (getStyle()) to discover what its "real" style characteristics are.
Parameters | |
---|---|
familyName |
String : May be null. The name of the font family. |
style |
int : The style (normal, bold, italic) of the typeface. e.g. NORMAL, BOLD, ITALIC, BOLD_ITALIC |
Returns | |
---|---|
Typeface |
The best matching typeface. |
Typeface createFromAsset (AssetManager mgr, String path)
Create a new typeface from the specified font data.
Parameters | |
---|---|
mgr |
AssetManager : The application's asset manager |
path |
String : The file name of the font data in the assets directory |
Returns | |
---|---|
Typeface |
The new typeface. |
Typeface createFromFile (File path)
Create a new typeface from the specified font file.
Parameters | |
---|---|
path |
File : The path to the font data. |
Returns | |
---|---|
Typeface |
The new typeface. |
Typeface createFromFile (String path)
Create a new typeface from the specified font file.
Parameters | |
---|---|
path |
String : The full path to the font data. |
Returns | |
---|---|
Typeface |
The new typeface. |
Typeface defaultFromStyle (int style)
Returns one of the default typeface objects, based on the specified style
Parameters | |
---|---|
style |
int
|
Returns | |
---|---|
Typeface |
the default typeface that corresponds to the style |
boolean equals (Object o)
Indicates whether some other object is "equal to" this one.
The equals
method implements an equivalence relation on non-null object references:
x
, x.equals(x)
should return true
. x
and y
, x.equals(y)
should return true
if and only if y.equals(x)
returns true
. x
, y
, and z
, if x.equals(y)
returns true
and y.equals(z)
returns true
, then x.equals(z)
should return true
. x
and y
, multiple invocations of x.equals(y)
consistently return true
or consistently return false
, provided no information used in equals
comparisons on the objects is modified. x
, x.equals(null)
should return false
. The equals
method for class Object
implements the most discriminating possible equivalence relation on objects; that is, for any non-null reference values x
and y
, this method returns true
if and only if x
and y
refer to the same object (x == y
has the value true
).
Note that it is generally necessary to override the hashCode
method whenever this method is overridden, so as to maintain the general contract for the hashCode
method, which states that equal objects must have equal hash codes.
Parameters | |
---|---|
o |
Object : the reference object with which to compare. |
Returns | |
---|---|
boolean |
true if this object is the same as the obj argument; false otherwise. |
int getStyle ()
Returns the typeface's intrinsic style attributes
Returns | |
---|---|
int |
int hashCode ()
Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by HashMap
.
The general contract of hashCode
is:
hashCode
method must consistently return the same integer, provided no information used in equals
comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application. equals(Object)
method, then calling the hashCode
method on each of the two objects must produce the same integer result. equals(java.lang.Object)
method, then calling the hashCode
method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables. As much as is reasonably practical, the hashCode method defined by class Object
does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the JavaTM programming language.)
Returns | |
---|---|
int |
a hash code value for this object. |
boolean isBold ()
Returns true if getStyle() has the BOLD bit set.
Returns | |
---|---|
boolean |
boolean isItalic ()
Returns true if getStyle() has the ITALIC bit set.
Returns | |
---|---|
boolean |
void finalize ()
Called by the garbage collector on an object when garbage collection determines that there are no more references to the object. A subclass overrides the finalize
method to dispose of system resources or to perform other cleanup.
The general contract of finalize
is that it is invoked if and when the JavaTM virtual machine has determined that there is no longer any means by which this object can be accessed by any thread that has not yet died, except as a result of an action taken by the finalization of some other object or class which is ready to be finalized. The finalize
method may take any action, including making this object available again to other threads; the usual purpose of finalize
, however, is to perform cleanup actions before the object is irrevocably discarded. For example, the finalize method for an object that represents an input/output connection might perform explicit I/O transactions to break the connection before the object is permanently discarded.
The finalize
method of class Object
performs no special action; it simply returns normally. Subclasses of Object
may override this definition.
The Java programming language does not guarantee which thread will invoke the finalize
method for any given object. It is guaranteed, however, that the thread that invokes finalize will not be holding any user-visible synchronization locks when finalize is invoked. If an uncaught exception is thrown by the finalize method, the exception is ignored and finalization of that object terminates.
After the finalize
method has been invoked for an object, no further action is taken until the Java virtual machine has again determined that there is no longer any means by which this object can be accessed by any thread that has not yet died, including possible actions by other objects or classes which are ready to be finalized, at which point the object may be discarded.
The finalize
method is never invoked more than once by a Java virtual machine for any given object.
Any exception thrown by the finalize
method causes the finalization of this object to be halted, but is otherwise ignored.
