中文文档

HighLights:

1. three layers, each layer has its unique func

   • the first is LoopViewPager,which provides the infinite func
   • the second is AutoScrollViewPager, which provides auto-start func
   • the third is AutoLoopViewPager,which enhances current widget,now supporting wrap_content attribute while use scale to definate the width/height ratio.

2. ViewPager.adapter and IPageIndicator all can be notifyDataSetChanged you can use adapter.notifyDataSetChanged and IPageIndicator.notifyDataSetChanged() to change the data source. you should override the getItemPosition(),and if you use fragment,you must use FragmentStatePagerAdapter.

       public int getItemPosition(Object object) {
           return POSITION_NONE;
       }
   

3. support setCurrentItem() method you can use setCurrentItem() method to specified the start position, the indicator changing as well.

4. implement IPageIndicator,you can have your own indicator
