Viewpager set the number of caches, page spacing, data updates

When using Viewpager common settings

1) mviewpager.setoffscreenpagelimit (2);//Set the number of cached view (actual 3, cache 2 + 1 being displayed)
2) Mviewpager.setpagemargin ((int) getresources (). Getdimensionpixeloffset (R.dimen.ui_5_dip));//Set Viewpager spacing per page card , similar to the Spacing property of gallery

3) Viewpager Update data problem:

The direct use of notifydatasetchanged is not updatable, and it is necessary to override GetItemPosition return constant Position_none (this constant is Viewpager band).
