我在Fragment中使用ViewPager。我正在关注Crashlytics中的崩溃报告。请帮助解决该问题的方法

请检查我在MovieFragmentBase内部使用的viewPagerAdapter代码。
class ViewPagerAdapter extends FragmentStatePagerAdapter {
private final List<Fragment> mFragmentList = new ArrayList<>();
private final List<String> mFragmentTitleList = new ArrayList<>();
public ViewPagerAdapter(FragmentManager manager) {
super(manager);
}
@Override
public Fragment getItem(int position) {
return mFragmentList.get(position);
}
@Override
public int getCount() {
return mFragmentList.size();
}
public void addFragment(Fragment fragment, String title) {
mFragmentList.add(fragment);
mFragmentTitleList.add(title);
}
@Override
public CharSequence getPageTitle(int position) {
return mFragmentTitleList.get(position);
}
}
答案 0 :(得分:0)
尝试在setRetainInstance(true);
的{{1}}中添加onCreate()
,可能会为您提供帮助
