ViewPager加载View过多导致的内存溢出解决方案

public class ViewPagerAdapter extends PagerAdapter {
private ArrayList<GroupAlbumPhotoBean> image_list;
private LayoutInflater inflater;

this.callback = callback;
}
@Override
public int getCount() {
if (image_list != null && image_list.size() > 0) {
return image_list.size();
} else {
return 0;
}
}
@Override
public boolean isViewFromObject(View arg0, Object arg1) {
return arg0 == arg1;
}
@Override
public void destroyItem(ViewGroup container, int position, Object object) {
container.removeView((View) object);
}
@Override
public Object instantiateItem(ViewGroup container, final int position) {
