Class Overview

Summary

Constants
int	ALIGN_BASELINE	A constant indicating that the bottom of this span should be aligned with the baseline of the surrounding text.
int	ALIGN_BOTTOM	A constant indicating that the bottom of this span should be aligned with the bottom of the surrounding text, i.e., at the same level as the lowest descender in the text.

Fields
protected final int	mVerticalAlignment

Public Constructors
	DynamicDrawableSpan ()

Protected Constructors
	DynamicDrawableSpan (int verticalAlignment)

Public Methods
void	draw ( Canvas canvas, CharSequence text, int start, int end, float x, int top, int y, int bottom, Paint paint)
abstract Drawable	getDrawable () Your subclass must implement this method to provide the bitmap to be drawn.
int	getSize ( Paint paint, CharSequence text, int start, int end, Paint.FontMetricsInt fm)
int	getVerticalAlignment () Returns the vertical alignment of this span, one of `ALIGN_BOTTOM` or `ALIGN_BASELINE` .

Inherited Methods

From class android.text.style.ReplacementSpan

abstract void	draw ( Canvas canvas, CharSequence text, int start, int end, float x, int top, int y, int bottom, Paint paint)
abstract int	getSize ( Paint paint, CharSequence text, int start, int end, Paint.FontMetricsInt fm)
void	updateDrawState ( TextPaint ds) This method does nothing, since ReplacementSpans are drawn explicitly instead of affecting Paint properties.
void	updateMeasureState ( TextPaint p) This method does nothing, since ReplacementSpans are measured explicitly instead of affecting Paint properties.

From class android.text.style.CharacterStyle

From class java.lang.Object

Object	clone () Creates and returns a copy of this `Object` .
boolean	equals ( Object o) Compares this instance with the specified object and indicates if they are equal.
void	finalize () Invoked when the garbage collector has detected that this instance is no longer reachable.
final Class <?>	getClass () Returns the unique instance of `Class` that represents this object's class.
int	hashCode () Returns an integer hash code for this object.
final void	notify () Causes a thread which is waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
final void	notifyAll () Causes all threads which are waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
String	toString () Returns a string containing a concise, human-readable description of this object.
final void	wait () Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object.
final void	wait (long millis, int nanos) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.
final void	wait (long millis) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.
