Ad Auto-carousel (perfect solution for artificial sliding after automatic rotation in sequence)

In the mobile phone client, the cycle of advertising is very common, in the online have seen some demo, a lot of writing is not too complete, the case of human non-intervention is indeed in accordance with the sequence of the rotation, but after the man to slide, the next automatic rotation is not to press the CurrentPosition play after the slide, Instead, it is played by jumping the position of the position before sliding manually. Spare time, the problem of a simple solution, for the latter to provide some ideas.
