android - fragment ViewPager内部需要很长时间才能加载子 fragment

我有一个问题，它需要很长的时间来加载数据，并显示只有当我滚动查看寻呼机。有几次我已经使用了asynctask，但是没有工作。换了标签后，我叫了同样的片段有人帮我吗？？
Here, is first time loaded data
After changing tab call same fragment
这是我的viewpager适配器

public class AdapterCategoryViewPager extends FragmentPagerAdapter {
Context context;
private List<Fragment> fragmentList;
private List<Type> typeList;

public AdapterCategoryViewPager(FragmentManager fm, Context context, List<Fragment> fragmentList, List<Type> typeList) {
    super(fm);
    this.context = context;
    this.fragmentList = fragmentList;
    this.typeList = typeList;
}


@Override
public Fragment getItem(int position) {
    return fragmentList.get(position);
}

@Override
public CharSequence getPageTitle(int position) {
    return typeList.get(position).getType().toString();
}

@Override
public int getCount() {
    return fragmentList.size();
}
}

这是我在异步任务中调用的这个函数的分类片段

private void setData(View v)
{
    addWomenCategory();
    ll_list.removeView(v);
    gridView.removeView(v);
    gridView.setMode(PullToRefreshBase.Mode.PULL_FROM_END);
    adapterCategory=new AdapterCategory(v.getContext(),categoryArrayList,height,width);
    gridView.setAdapter(adapterCategory);
    g=(GridView) gridView.getRefreshableView();
    g.setHorizontalSpacing(h7);
    g.setVerticalSpacing(h7);
   // g.setEnabled(false);

    gridView.setOnRefreshListener(new PullToRefreshBase.OnRefreshListener<GridView>() {
        @Override
        public void onRefresh(final PullToRefreshBase<GridView> refreshView) {
            gridView.postDelayed(new Runnable() {
                @Override
                public void run() {
                    refreshView.getLoadingLayoutProxy().setRefreshingLabel("Loding Data...");
                    refreshView.getLoadingLayoutProxy().setReleaseLabel("Refresh complete");
                    addWomenCategory();
                    adapterCategory.notifyDataSetChanged();
                    gridView.setRefreshing(false);
                    gridView.onRefreshComplete();

                }
            },2000);
        }
    });
}

这里是我的homeFragment，它实际上在数组列表中添加了fragments类别这个函数我在asynctask中也调用过

private void setData(View v)
{
    addType();
    pager.setOffscreenPageLimit(3);
    adapterType=new AdapterType(typeArrayList,v.getContext(),height,width);
    fragmentList.add(new FragmentListCategory());
    fragmentList.add(new FragmentMenListCategory());
    fragmentList.add(new FragmentKidListCategory());
    fragmentList.add(new FragmentListCategory());
    fragmentList.add(new FragmentMenListCategory());
    fragmentList.add(new FragmentKidListCategory());

    pager.setAdapter(new AdapterCategoryViewPager(getFragmentManager(),v.getContext(),fragmentList,typeArrayList));

   tabs.setViewPager(pager);
    setUpTabStrip(v);


}

最佳答案

我使用通用的imageloader库来显示图像，并且每次在适配器中初始化它的对象来解决这个问题我在主活动的oncreate（）方法的整个应用程序中只初始化该配置对象一次
