ScaleXSpan

public class ScaleXSpan
extends MetricAffectingSpan implements ParcelableSpan

java.lang.Object
↳	android.text.style.CharacterStyle
	↳	android.text.style.MetricAffectingSpan
		↳	android.text.style.ScaleXSpan

Scales horizontally the size of the text to which it's attached by a certain factor.

Values > 1.0 will stretch the text wider. Values < 1.0 will stretch the text narrower.

For example, a ScaleXSpan that stretches the text size by 100% can be constructed like this:

SpannableString string = new SpannableString("Text with ScaleX span");
string.setSpan(new ScaleXSpan(2f), 10, 16, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);

Text scaled by 100% with ScaleXSpan.

Summary

Inherited constants

From interface android.os.Parcelable

`int`	`CONTENTS_FILE_DESCRIPTOR` Descriptor bit used with `describeContents()`: indicates that the Parcelable object's flattened representation includes a file descriptor.
`int`	`PARCELABLE_WRITE_RETURN_VALUE` Flag for use with `writeToParcel(Parcel, int)`: the object being written is a return value, that is the result of a function such as "`Parcelable someFunction()`", "`void someFunction(out Parcelable)`", or "`void someFunction(inout Parcelable)`".

Public constructors
`ScaleXSpan(float proportion)` Creates a `ScaleXSpan` based on a proportion.
`ScaleXSpan(Parcel src)` Creates a `ScaleXSpan` from a parcel.

Public methods
`int`	`describeContents()` Describe the kinds of special objects contained in this Parcelable instance's marshaled representation.
`float`	`getScaleX()` Get the horizontal scale factor for the text.
`int`	`getSpanTypeId()` Return a special type identifier for this span class.
`void`	`updateDrawState(TextPaint ds)`
`void`	`updateMeasureState(TextPaint ds)` Classes that extend MetricAffectingSpan implement this method to update the text formatting in a way that can change the width or height of characters.
`void`	`writeToParcel(Parcel dest, int flags)` Flatten this object in to a Parcel.

Inherited methods

From class


        
          android.text.style.MetricAffectingSpan

`MetricAffectingSpan`	`getUnderlying()` Returns "this" for most MetricAffectingSpans, but for MetricAffectingSpans that were generated by `CharacterStyle.wrap(CharacterStyle)`, returns the underlying MetricAffectingSpan.
`abstract void`	`updateMeasureState(TextPaint textPaint)` Classes that extend MetricAffectingSpan implement this method to update the text formatting in a way that can change the width or height of characters.

From class


        
          android.text.style.CharacterStyle

`CharacterStyle`	`getUnderlying()` Returns "this" for most CharacterStyles, but for CharacterStyles that were generated by `wrap(CharacterStyle)`, returns the underlying CharacterStyle.
`abstract void`	`updateDrawState(TextPaint tp)`
`static CharacterStyle`	`wrap(CharacterStyle cs)` A given CharacterStyle can only applied to a single region of a given Spanned.

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.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long timeout, 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 timeout)` 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.
`final void`	`wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.

From interface


        
          android.text.ParcelableSpan


      getSpanTypeId()

Return a special type identifier for this span class.

From interface


        
          android.os.Parcelable

`abstract int`	`describeContents()` Describe the kinds of special objects contained in this Parcelable instance's marshaled representation.
`abstract void`	`writeToParcel(Parcel dest, int flags)` Flatten this object in to a Parcel.

Public constructors

ScaleXSpan

public ScaleXSpan (float proportion)

Creates a ScaleXSpan based on a proportion. Values > 1.0 will stretch the text wider. Values < 1.0 will stretch the text narrower.

Parameters
`proportion`	`float`: the horizontal scale factor. Value is 0 or greater

ScaleXSpan

public ScaleXSpan (Parcel src)

Creates a ScaleXSpan from a parcel.

Parameters
`src`	`Parcel`: This value cannot be `null`.

Public methods

describeContents

public int describeContents ()

Describe the kinds of special objects contained in this Parcelable instance's marshaled representation. For example, if the object will include a file descriptor in the output of writeToParcel(android.os.Parcel, int), the return value of this method must include the CONTENTS_FILE_DESCRIPTOR bit.

Returns
`int`	a bitmask indicating the set of special object types marshaled by this Parcelable object instance. Value is either `0` or `CONTENTS_FILE_DESCRIPTOR`

getScaleX

public float getScaleX ()

Get the horizontal scale factor for the text.

Returns
`float`	the horizontal scale factor.

getSpanTypeId

public int getSpanTypeId ()

Return a special type identifier for this span class.

Returns
`int`

updateDrawState

public void updateDrawState (TextPaint ds)

Parameters
`ds`	`TextPaint`

updateMeasureState

public void updateMeasureState (TextPaint ds)

Classes that extend MetricAffectingSpan implement this method to update the text formatting in a way that can change the width or height of characters.

Parameters
`ds`	`TextPaint`: the paint used for drawing the text This value cannot be `null`.

writeToParcel

public void writeToParcel (Parcel dest, 
                int flags)

Flatten this object in to a Parcel.

Parameters
`dest`	`Parcel`: This value cannot be `null`.
`flags`	`int`: Additional flags about how the object should be written. May be 0 or `Parcelable.PARCELABLE_WRITE_RETURN_VALUE`. Value is either `0` or a combination of `Parcelable.PARCELABLE_WRITE_RETURN_VALUE`, and android.os.Parcelable.PARCELABLE_ELIDE_DUPLICATES
