Added in API level 24

Spanned fromHtml (String source, 
                int flags)

`source`	`String`
`flags`	`int`

Returns
`Spanned`

fromHtml

Added in API level 1

Spanned fromHtml (String source, 
                Html.ImageGetter imageGetter, 
                Html.TagHandler tagHandler)

This method was deprecated in API level 24.
use fromHtml(String, int, ImageGetter, TagHandler) instead.

Returns displayable styled text from the provided HTML string with the legacy flags FROM_HTML_MODE_LEGACY.

Parameters
`source`	`String`
`imageGetter`	`Html.ImageGetter`
`tagHandler`	`Html.TagHandler`

`Spanned`

fromHtml

Added in API level 24

Spanned fromHtml (String source,

                Html.ImageGetter imageGetter, 
                Html.TagHandler tagHandler)

Returns displayable styled text from the provided HTML string. Any <img> tags in the HTML will use the specified ImageGetter to request a representation of the image (use null if you don't want this) and the specified TagHandler to handle unknown tags (specify null if you don't want this).

This uses TagSoup to handle real HTML, including all of the brokenness found in the wild.

Parameters
`source`	`String`
`flags`	`int`
`imageGetter`	`Html.ImageGetter`
`tagHandler`	`Html.TagHandler`
