IconMarginSpan

public class IconMarginSpan
extends Object implements LeadingMarginSpan, LineHeightSpan

java.lang.Object
↳	android.text.style.IconMarginSpan

Paragraph affecting span, that draws a bitmap at the beginning of a text. The span also allows setting a padding between the bitmap and the text. The default value of the padding is 0px. The span should be attached from the first character of the text.

For example, an IconMarginSpan with a bitmap and a padding of 30px can be set like this:

 SpannableString string = new SpannableString("Text with icon and padding");
 string.setSpan(new IconMarginSpan(bitmap, 30), 0, string.length(),
 Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);

Summary

Public constructors
`IconMarginSpan(Bitmap bitmap)` Creates an `IconMarginSpan` from a `Bitmap`.
`IconMarginSpan(Bitmap bitmap, int pad)` Creates an `IconMarginSpan` from a `Bitmap`.

Public methods
`void`	`chooseHeight(CharSequence text, int start, int end, int istartv, int v, Paint.FontMetricsInt fm)` Classes that implement this should define how the height is being calculated.
`void`	`drawLeadingMargin(Canvas c, Paint p, int x, int dir, int top, int baseline, int bottom, CharSequence text, int start, int end, boolean first, Layout layout)` Renders the leading margin.
`int`	`getLeadingMargin(boolean first)` Returns the amount by which to adjust the leading margin.

Inherited methods

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.

          android.text.style.LineHeightSpan


      chooseHeight(CharSequence text, int start, int end, int spanstartv, int lineHeight, Paint.FontMetricsInt fm)

Classes that implement this should define how the height is being calculated.

Public constructors

IconMarginSpan

public IconMarginSpan (Bitmap bitmap)

Creates an IconMarginSpan from a Bitmap.

Parameters
`bitmap`	`Bitmap`: bitmap to be rendered at the beginning of the text This value cannot be `null`.

IconMarginSpan

public IconMarginSpan (Bitmap bitmap, 
                int pad)

Creates an IconMarginSpan from a Bitmap.

Parameters
`bitmap`	`Bitmap`: bitmap to be rendered at the beginning of the text This value cannot be `null`.
`pad`	`int`: padding width, in pixels, between the bitmap and the text Value is 0 or greater

Public methods

chooseHeight

public void chooseHeight (CharSequence text, 
                int start, 
                int end, 
                int istartv, 
                int v, 
                Paint.FontMetricsInt fm)

Classes that implement this should define how the height is being calculated.

Parameters
`text`	`CharSequence`: the text
`start`	`int`: the start of the line
`end`	`int`: the end of the line
`istartv`	`int`: the start of the span
`v`	`int`: the line height
`fm`	`Paint.FontMetricsInt`: font metrics of the paint, in integers

drawLeadingMargin

public void drawLeadingMargin (Canvas c, 
                Paint p, 
                int x, 
                int dir, 
                int top, 
                int baseline, 
                int bottom, 
                CharSequence text, 
                int start, 
                int end, 
                boolean first, 
                Layout layout)

Renders the leading margin. This is called before the margin has been adjusted by the value returned by getLeadingMargin(boolean).

Parameters
`c`	`Canvas`: the canvas
`p`	`Paint`: the paint. The this should be left unchanged on exit.
`x`	`int`: the current position of the margin
`dir`	`int`: the base direction of the paragraph; if negative, the margin is to the right of the text, otherwise it is to the left.
`top`	`int`: the top of the line
`baseline`	`int`: the baseline of the line
`bottom`	`int`: the bottom of the line
`text`	`CharSequence`: the text
`start`	`int`: the start of the line
`end`	`int`: the end of the line
`first`	`boolean`: true if this is the first line of its paragraph
`layout`	`Layout`: the layout containing this line

getLeadingMargin

public int getLeadingMargin (boolean first)

Returns the amount by which to adjust the leading margin. Positive values move away from the leading edge of the paragraph, negative values move towards it.

Parameters
`first`	`boolean`: true if the request is for the first line of a paragraph, false for subsequent lines

Returns
`int`	the offset for the margin.
