Android 使用viewpager实现无限循环(定时+手动)

private ViewPager mViewPager; //页面 public AdapterCycle(Context context, ViewPager viewPager,

List<Drawable> list) {

mContext = context; mInflater = LayoutInflater.from(context);

mViewPager = viewPager; if (list != null) {

//无论是否多于1个，都要初始化第一个（index:0） mViews = new LinkedList<View>();

ImageView view = (ImageView) mInflater.inflate( R.layout.activity_main_item_cycle, null);

Drawable drawable = list.get(list.size() - 1); view.setImageDrawable(drawable);

mViews.add(view); //注意，如果不只1个，mViews比mList多两个（头尾各多一个）

//假设：mList为mList[0~N-1], mViews为mViews[0~N+1] // mViews[0]放mList[N-1], mViews[i]放mList[i-1], mViews[N+1]放mList[0]

// mViews[1~N]用于循环；首位之前的mViews[0]和末尾之后的mViews[N+1]用于跳转 // 首位之前的mViews[0]，跳转到末尾（N）；末位之后的mViews[N+1]，跳转到首位（1）

if( list.size() > 1) { //多于1个要循环 for (Drawable d : list) { //中间的N个（index:1~N）

ImageView v = (ImageView) mInflater.inflate( R.layout.activity_main_item_cycle, null);

v.setImageDrawable(d); mViews.add(v);

} //最后一个（index:N+1）

view = (ImageView) mInflater.inflate( R.layout.activity_main_item_cycle, null);

drawable = dList.get(0); view.setImageDrawable(drawable);

mViews.add(view); }

} }

@Override public int getCount() {

return mViews.size(); }

@Override public boolean isViewFromObject(View view, Object object) {

return view == object; }

@Override public void destroyItem(ViewGroup container, int position, Object object) {
