You can also rewrite other methods.

instantiateItem(ViewGroup container, int position)getItemPosition(Object object)destroyItem(ViewGroup container, int position,Object object)isViewFromObject(View arg0, Object arg1)

Note that the layout file must be written in this way.

A widget is used to display the sliding left and right interfaces. If an xml layout file is not loaded, the widget does not display the content of android: id = "@ + id/main_viewpager" android: layout_width = "wrap_content" android: layout_height = "wrap_content" android: layout_gravity = "center">
