/**
* Makes the SlideView working on MMSConformance Mode. The view will be re-layout to the linear
* view.
*
* <p>This is Chinese requirement about mms conformance. The most popular Mms service in China is
* newspaper which is MMS conformance, normally it mixes the image and text and has a number of
* slides. The AbsoluteLayout doesn't have good user experience for this kind of message, for
* example,
*
* <p>1. AbsoluteLayout exactly follows the smil's layout which is not optimized, and actually, no
* other MMS applications follow the smil's layout, they adjust the layout according their screen
* size. MMS conformance doc also allows the implementation to adjust the layout.
*
* <p>2. The TextView is fixed in the small area of screen, and other part of screen is empty once
* there is no image in the current slide.
*
* <p>3. The TextView is scrollable in a small area of screen and the font size is small which
* make the user experience bad.
*
* <p>The better UI for the MMS conformance message could be putting the image/video and text in a
* linear layout view and making them scrollable together.
*
* <p>Another reason for only applying the LinearLayout to the MMS conformance message is that the
* AbsoluteLayout has ability to play image and video in a same screen. which shouldn't be broken.
