?自定義viewpager——可開關切換動畫

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) {//去除頁面切換時的滑動翻頁效果super.setCurrentItem(item, true);} }

viewpager的adapter

/*** 作者：created by meixi* 郵箱：1085220040@qq.com* 日期：2020/1/6 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調用即可

private NoAnimationViewPager vp; private ViewPagerAdapter mAdapter; private List<GridView> gridList = new ArrayList<>(); private int WHAT_AUTO_PLAY = 1000; private int autoPlayDuration = 2000;//刷新間隔時間 private int num = 0; private boolean ifauto = true; private List<GongXuEntity> mGongXuEntities = new ArrayList<>(); protected Handler mHandler = new Handler(new Handler.Callback() {@Overridepublic boolean handleMessage(Message msg) {if (msg.what == WHAT_AUTO_PLAY) {Log.e("lgq", "==33==" + ifauto);if (ifauto){num++;if (num==0){vp.setCurrentItem(num,false);}else {vp.setCurrentItem(num,true);}}if (mGongXuEntities.size() - 1 == num) {num = -1;}mHandler.sendEmptyMessageDelayed(WHAT_AUTO_PLAY, autoPlayDuration);}return false;} });

mAdapter = new ViewPagerAdapter(); vp.setAdapter(mAdapter); getdata(); showHostsj(); vp.setOnTouchListener(new View.OnTouchListener() {@Overridepublic boolean onTouch(View v, MotionEvent event) {if (event.getAction() == MotionEvent.ACTION_DOWN || event.getAction() == MotionEvent.ACTION_MOVE) {ifauto = false;}if (event.getAction() == MotionEvent.ACTION_UP) {ifauto = true;}return false;}}); //圓點指示器mHandler.sendEmptyMessageDelayed(WHAT_AUTO_PLAY, autoPlayDuration);
