我有ViewPager（幻燈片），並有3個圖像。有三個圖像通過互聯網下載。如果我改變圖片到服務器上的另一臺服務器，鏈接保持不變，但在應用程序中的圖片不會改變，仍然是同一個，這是在緩存ViewPager Glide
public class ViewPagerAdapter extends PagerAdapter {
private Context context;
private LayoutInflater layoutInflater;
private String [] image = {"http://rgho.st/7hDcbyT2F/image.png",
"http://guid-korenovsk.my1.ru/logos.png",

public ViewPagerAdapter(Context context) {
this.context = context;
}
@Override
public int getCount() {
return image.length;
}
@Override
public boolean isViewFromObject(View view, Object object) {
return view == object;
}
@Override
public Object instantiateItem(ViewGroup container, int position) {
layoutInflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View view = layoutInflater.inflate(R.layout.bulding_layout, null);
ImageView imageView = (ImageView)view.findViewById(R.id.imageViewPager);
Glide.with(context)
.load(image[position])
.diskCacheStrategy(DiskCacheStrategy.SOURCE)
.into(imageView);
ViewPager vp = (ViewPager)container;
vp.addView(view,0);
return view;
}
@Override
public void destroyItem(ViewGroup container, int position, Object object) {
ViewPager vp = (ViewPager)container;
View view = (View)object;
vp.removeView(view);
}
}
公衆類MyTimerTask擴展的TimerTask {
@Override
public void run() {
getActivity().runOnUiThread(new Runnable() {
@Override
public void run() {
if(viewPagerAds.getCurrentItem() == 0){
viewPagerAds.setCurrentItem(1);
}else if(viewPagerAds.getCurrentItem() == 1){
viewPagerAds.setCurrentItem(2);
}else viewPagerAds.setCurrentItem(0);
}
});
}
}
