final Class<? extends Object>	getClass() Returns the unique instance of Class which 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(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.

Constants

public static final int ALIGN_BASELINE

A constant indicating that the bottom of this span should be aligned with the baseline of the surrounding text.

Constant Value: 1 (0x00000001)

public static final 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

public DynamicDrawableSpan ()

Protected Constructors

protected DynamicDrawableSpan (int verticalAlignment)

Parameters

verticalAlignment	one of ALIGN_BOTTOM or ALIGN_BASELINE.

Public Methods

public void draw (Canvas canvas, CharSequence text, int start, int end, float x, int top, int y, int bottom, Paint paint)

public abstract Drawable getDrawable ()

Your subclass must implement this method to provide the bitmap to be drawn. The dimensions of the bitmap must be the same from each call to the next.

public int getSize (Paint paint, CharSequence text, int start, int end, Paint.FontMetricsInt fm)

public int getVerticalAlignment ()

Returns the vertical alignment of this span, one of ALIGN_BOTTOM or ALIGN_BASELINE.
