Span that replaces the text it's attached to with a Drawable
that can be aligned with
the bottom or with the baseline of the surrounding text.

Remarks
Span that replaces the text it's attached to with a Drawable
that can be aligned with the bottom or with the baseline of the surrounding text. The drawable can be constructed from varied sources: <ul> <li>Bitmap
- see #ImageSpan(Context, Bitmap)
and #ImageSpan(Context, Bitmap, int)
</li> <li>Drawable
- see #ImageSpan(Drawable, int)
</li> <li>resource id - see #ImageSpan(Context, int, int)
</li> <li>Uri
- see #ImageSpan(Context, Uri, int)
</li> </ul> The default value for the vertical alignment is DynamicDrawableSpan#ALIGN_BOTTOM
For example, an ImagedSpan
can be used like this:
SpannableString string = new SpannableString("Bottom: span.\nBaseline: span.");
// using the default alignment: ALIGN_BOTTOM
string.setSpan(new ImageSpan(this, R.mipmap.ic_launcher), 7, 8, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
string.setSpan(new ImageSpan(this, R.mipmap.ic_launcher, DynamicDrawableSpan.ALIGN_BASELINE),
22, 23, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
