android ViewPager 和 listview的共存问题
更新数据后，没有看到新页面的原因是：没有重写这个方法//如果要更新VeiwPager的页面，就必须重写这个方法，如果不重写，如果刷新数据，虽然成功但是显示不了。下面是官方文档说明 /** Called when the host view is attempting to determine if an item's position has changed. Returns POSITION_UNCHANGED if the position of the given item has not changed or POSITION_NONE if the item is no longer present in the adapter. The default implementation assumes that items will never change position and always returns POSITION_UNCHANGED. */ @Override public int getItemPosition(Object object) { return POSITION_NONE; } ??
