Fixed a bug that occurs after adapter.add(item);

    when I called adapter.add(Item), all the childViews going to wrong position in editmode.
    but I already fixed it. I have noticed that AbstractDynamicGridAdapter#nextStableId has not been changed in the AbstractDynamicGridAdapter#addAllStableId method.
    So I was added "nextStableId=mIdMap.size();" to the end of the addAllStatbleId method and it works fine.

    My English is not good, hope you can understand me, thank you!
