↳ | 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).

From class
java.lang.Object
|
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.
The NORMAL style of the default monospace typeface.
The NORMAL style of the default sans serif typeface.
The NORMAL style of the default serif typeface.
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.
familyName | May be null. The name of the font family. |
---|---|
style | The style (normal, bold, italic) of the typeface. e.g. NORMAL, BOLD, ITALIC, BOLD_ITALIC |
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.
family | May be null. The name of the existing type face. |
---|---|
style | The style (normal, bold, italic) of the typeface. e.g. NORMAL, BOLD, ITALIC, BOLD_ITALIC |
Create a new typeface from the specified font data.
mgr | The application's asset manager |
---|---|
path | The file name of the font data in the assets directory |
Create a new typeface from the specified font file.
path | The full path to the font data. |

Create a new typeface from the specified font file.
path | The path to the font data. |

Returns one of the default typeface objects, based on the specified style
Compares this instance with the specified object and indicates if they
are equal. In order to be equal,
o
must represent the same object
as this instance using a class-specific comparison. The general contract
is that this comparison should be reflexive, symmetric, and transitive.
Also, no object reference other than null is equal to null.
The default implementation returns
true
only if
this ==
o
. See
Writing a correct
equals
method
if you intend implementing your own
equals
method.
The general contract for the
equals
and
hashCode()
methods is that if
equals
returns
true
for
any two objects, then
hashCode()
must return the same value for
these objects. This means that subclasses of
Object
usually
override either both methods or neither of them.
o | the object to compare this instance with. |
---|
true
if the specified object is equal to this
Object
;
false
otherwise.
Returns an integer hash code for this object. By contract, any two
objects for which
equals(Object)
returns
true
must return
the same hash code value. This means that subclasses of
Object
usually override both methods or neither method.
Note that hash values must not change over time unless information used in equals comparisons also changes.
See
Writing a correct
hashCode
method
if you intend implementing your own
hashCode
method.
Returns true if getStyle() has the BOLD bit set.
Returns true if getStyle() has the ITALIC bit set.
Invoked when the garbage collector has detected that this instance is no longer reachable. The default implementation does nothing, but this method can be overridden to free resources.
Note that objects that override
finalize
are significantly more expensive than
objects that don't. Finalizers may be run a long time after the object is no longer
reachable, depending on memory pressure, so it's a bad idea to rely on them for cleanup.
Note also that finalizers are run on a single VM-wide finalizer thread,
so doing blocking work in a finalizer is a bad idea. A finalizer is usually only necessary
for a class that has a native peer and needs to call a native method to destroy that peer.
Even then, it's better to provide an explicit
close
method (and implement
Closeable
), and insist that callers manually dispose of instances. This
works well for something like files, but less well for something like a
BigInteger
where typical calling code would have to deal with lots of temporaries. Unfortunately,
code that creates lots of temporaries is the worst kind of code from the point of view of
the single finalizer thread.
If you
must
use finalizers, consider at least providing your own
ReferenceQueue
and having your own thread process that queue.
Unlike constructors, finalizers are not automatically chained. You are responsible for
calling
super.finalize()
yourself.
Uncaught exceptions thrown by finalizers are ignored and do not terminate the finalizer thread. See Effective Java Item 7, "Avoid finalizers" for more.
