Как нарисовать макет внутри макета
У меня есть приложение, где после нажатия на статистику я вызываю StatsFragment. StatsFragment использует макет фрагмента фрагмента xml, в котором есть TabLayout и CustomViewPager. Однако, когда я нажал на Статистика, так что мой StatsFragment называется данными, там не рисуется. После того, как я нажму на некоторые вкладки, данные будут там. Проблема с начальным рисунком. Из Как вы можете узнать, когда макет был нарисован? я знаю, что буду использовать каким-то образом ViewTreeObserver, но не могу найти способ, где и как.

Из того, что я могу сказать, вы не делаете правильные вещи в нужное время. Когда onCreateView из вашего фрагмента вызывается, вы раздуваете соответствующий макет, но не устанавливаете там никакого значения.
Просто поменяйте местами весь код onActivityCreated в onCreateView следует сделать трюк, как следует:
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
// Inflate the layout for this fragment
View layout = inflater.inflate(R.layout.fragment_stats, container, false);
TabLayout tabLayout = (TabLayout)layout.findViewById(R.id.tab_layout);
tabLayout.addTab(tabLayout.newTab().setText("7 days"));
tabLayout.addTab(tabLayout.newTab().setText("1 month"));
tabLayout.addTab(tabLayout.newTab().setText("1 year"));
tabLayout.setTabGravity(TabLayout.GRAVITY_FILL);
final CustomViewPager viewPager = (CustomViewPager) layout.findViewById(R.id.pager);
final PagerAdapter adapter = new PagerAdapter(getActivity().getSupportFragmentManager(), tabLayout.getTabCount());
viewPager.setAdapter(adapter);
viewPager.setPagingEnabled(false);
viewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));
tabLayout.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
@Override
public void onTabSelected(TabLayout.Tab tab) {
viewPager.setCurrentItem(tab.getPosition());
processChanges((adapter.getItem(tab.getPosition())).getView(),tab.getPosition());
}
@Override
public void onTabUnselected(TabLayout.Tab tab) {
}
@Override
public void onTabReselected(TabLayout.Tab tab) {
}
});
return (layout);
}
РЕДАКТИРОВАТЬ: после второго (и более пристального) просмотра вашего кода, лучшей идеей будет иметь фрагменты, управляющие вашими вкладками, чтобы вы могли поместить свою логику туда (и разместить их на каждой вкладке). Для этого:
Шаг 1: Создайте новый класс фрагмента для ваших страниц
public abstract class PageFragment extends Fragment {
private int pageNumber;
public static PageFragment newInstance(int page) {
Bundle args = new Bundle();
args.putInt("page_number", page);
PageFragment fragment = new PageFragment();
fragment.setArguments(args);
return (fragment);
}
public PageFragment(){}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (getArguments() != null) {
pageNumber = getArguments().getInt("page_number");
}
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View layout = inflater.inflate(R.layout.tab_fragment, container, false);
//Get all the views you need for your page, using
//layout.findViewById();
//Then you will need to call processChanges for that page
processChanges(layout, pageNumber);
return (layout);
}
//Also add here all the logic associated with processChanges
}
Шаг 2 будет состоять в том, чтобы получить ссылки на ваши фрагменты в вашем StatsFragment и добавить эти фрагменты в ваш пейджер:
private PageFragment pageOne;
private PageFragment pageTwo;
private PageFragment pageThree;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
// Inflate the layout for this fragment
View layout = inflater.inflate(R.layout.fragment_stats, container, false);
TabLayout tabLayout = (TabLayout)layout.findViewById(R.id.tab_layout);
pageOne = PageFragment.newInstance(0);
pageTwo = PageFragment.newInstance(1);
pageThree = PageFragment.newInstance(2);
tabLayout.addFragment(pageOne, "7 days");
tabLayout.addFragment(pageTwo, "1 month");
tabLayout.addFragment(pageThree, "1 year");
tabLayout.setTabGravity(TabLayout.GRAVITY_FILL);
}
Шаг 3: Наконец, вам понадобится специальный адаптер для пейджера, который будет содержать заголовки и фрагменты вашего пейджера:
public class MyViewPagerAdapter extends FragmentPagerAdapter {
private List<Fragment> mFragments = new ArrayList<>();
private List<String> mTitles = new ArrayList<>();
public MyViewPagerAdapter(FragmentManager fm) {
super(fm);
}
public void addFragment(Fragment fragment, String title) {
mFragments.add(fragment);
mTitles.add(title);
}
@Override
public Fragment getItem(int position) {
return (mFragments.get(position));
}
@Override
public int getCount() {
return (mFragments.size());
}
@Override
public String getPageTitle(int position) {
return (mTitles.get(position));
}
}
Чтобы использовать его, просто создайте его через (вместо вашего PagerAdapter)
final MyPagerAdapter adapter = new MyPagerAdapter(getActivity().getSupportFragmentManager());
По словам Нсимона я обновляю текущее состояние. Это решило проблему с начальным экраном для меня. Большое спасибо NSimon.

mFragments.add(fragment);
mTitles.add(title);
}
@Override
