Remarks
A span which adds a drawable and a padding to the paragraph it's attached to.
If the height of the drawable is bigger than the height of the line it's attached to then the line height is increased to fit the drawable. DrawableMarginSpan allows setting a padding between the drawable and the text. The default value is 0. The span must be set from the beginning of the text, otherwise either the span won't be rendered or it will be rendered incorrectly.
For example, a drawable and a padding of 20px can be added like this:
{@code SpannableString string = new SpannableString("Text with a drawable.");
string.setSpan(new DrawableMarginSpan(drawable, 20), 0, string.length(),
Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);}

Methods
| Name | Description |
|---|---|
| ChooseHeight(ICharSequence, Int32, Int32, Int32, Int32, Paint+FontMetricsInt) |
Increases the last line's metrics when needed to fit the drawable's height. |
| ChooseHeight(String, Int32, Int32, Int32, Int32, Paint+FontMetricsInt) |
Classes that implement this should define how the height is being calculated. |

Releases the resources held by this Java peer. (Inherited from Object) |
| Dispose(Boolean) |
Releases the resources held by this Java peer. (Inherited from Object) |
| DisposeUnlessReferenced() |
Asks the value manager to dispose this peer unless its mapping retains this same managed instance. (Inherited from JavaObject) |
