效果
单个item样式
多个item样式
横向item
自定义viewpager——可开关切换动画
public class NoAnimationViewPager extends ViewPager {public NoAnimationViewPager(Context context) {super(context);}public NoAnimationViewPager(Context context, AttributeSet attrs) {super(context, attrs);}@Overridepublic void setCurrentItem(int item, boolean smoothScroll) {super.setCurrentItem(item, smoothScroll);}@Overridepublic void setCurrentItem(int item) {//去除页面切换时的滑动翻页效果super.setCurrentItem(item, true);}}
viewpager的adapter
/*** 作者：created by meixi* 邮箱：108520@* 日期：/1/6 15:40*/public class ViewPagerAdapter extends PagerAdapter {private List<GridView> gridList;public ViewPagerAdapter() {gridList = new ArrayList<>();}public void add(List<GridView> datas) {if (gridList.size() > 0) {gridList.clear();}gridList.addAll(datas);notifyDataSetChanged();}@Overridepublic int getCount() {return gridList.size();}@Overridepublic int getItemPosition(Object object) {return POSITION_NONE;}@Overridepublic boolean isViewFromObject(View view, Object object) {return view == object;}@Overridepublic Object instantiateItem(ViewGroup container, int position) {container.addView(gridList.get(position));return gridList.get(position);}@Overridepublic void destroyItem(ViewGroup container, int position, Object object) {container.removeView((View) object);}}
activity调用即可
