我有viewPager其中包含的片段的每个这些片段的具有viewpager以显示图像和横幅嵌套片段getchildfragmentmanager引起崩溃
现在到我传递getChildFragmentManager（）如下面的每个片段图片适配器
CarouselAdapter carouselAdapter = new CarouselAdapter(getChildFragmentManager());
但上面的代码导致崩溃，同时改变viewpager选项卡显示以下消息
java.lang.IllegalArgumentException: No view found for id 0x7f1000ef
但是，如果我通过getFragmentMana ger（）它没有崩溃，但适配器在一段时间内空白任何想法如何处理嵌套的片段。
我使用FragmentPagerAdapter两个viewpagers但还是它不工作
以下是系统崩溃日志
java.lang.IllegalArgumentException: No view found for id 0x7f1000ef (com.packagename:id/viewPagerBanners) for fragment MainBannerFragmentNew{308cb84 #0 id=0x7f1000ef android:switcher:2131755247:0}

以下是旋转木马适配器代码
public class CarouselAdapter extends FragmentPagerAdapter {
private List<CarouselItem> carouselItemsList;
public CarouselAdapter(FragmentManager fm, List<CarouselItem> carouselItemsList) {
super(fm);
this.carouselItemsList = carouselItemsList;
}
@Override
public Fragment getItem(int position) {
return MainBannerFragmentNew.newInstance(R.drawable.gray_logo, carouselItemsList.get(position));
}
@Override
public int getCount() {
return carouselItemsList.size();
}
@Override
public void destroyItem(ViewGroup container, int position, Object object) {
super.destroyItem(container, position, object);
}
}
以下是滑片适配器代码
public class HomeTabsPagerAdapter extends FragmentPagerAdapter {
ArrayList<HomeTabItem> homeTabItems;
public HomeTabsPagerAdapter(FragmentManager manager, ArrayList<HomeTabItem> homeTabItems) {
super(manager);
this.homeTabItems = homeTabItems;
}
@Override
public Fragment getItem(int position) {
HomeTabItem homeTabItem = homeTabItems.get(position);
return OfferZoneFragment.newInstance(homeTabItem.getId());
}
@Override
public int getCount() {
return homeTabItems.size();
}
@Override
public CharSequence getPageTitle(int position) {
return homeTabItems.get(position).getTitle();
}
}
每个滑动片片段具有recyclerview这recylerview包含旋转木马viewpager下面是bindview
代码((BannerHolder) holder).viewPager.setAdapter(new CarouselAdapter(fragmentManager, homePageItems.get(position).carouselItems));
((BannerHolder) holder).circlePageIndicator.setViewPager(((BannerHolder) holder).viewPager);
final float density = context.getResources().getDisplayMetrics().density;
((BannerHolder) holder).circlePageIndicator.setBackgroundColor(0x00000000);
((BannerHolder) holder).circlePageIndicator.setRadius(5 * density);
((BannerHolder) holder).circlePageIndicator.setFillColor(ContextCompat.getColor(context, R.color.appthemecolor));
((BannerHolder) holder).circlePageIndicator.setPageColor(0xFFFFFFFF);
((BannerHolder) holder).circlePageIndicator.setStrokeColor(0x00000000);
((BannerHolder) holder).circlePageIndicator.setStrokeWidth(2 * density);
if (((BannerHolder) holder).viewPager.getAdapter().getCount() <= 1) {
((BannerHolder) holder).circlePageIndicator.setVisibility(View.GONE);
} else {
((BannerHolder) holder).circlePageIndicator.setVisibility(View.VISIBLE);
}
使用getChildFragmentManager（）是正确的方法。不知道为什么它不适合你的情况。检查其他事情是否正确。 – Pruthviraj
是你制作的'CarouselAdapter'还是从任何图书馆借来的？ – Nilabja
请提供导致崩溃和完整崩溃日志的代码。 –
