我的应用有两个选项卡(Android Design Support Library),这是使用ViewPagerAdapter的片段:
public class ListaCanali extends Fragment {
public static TabLayout tabLayout;
public static ViewPager viewPager;
public static int int_items = 2 ;
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
View v =inflater.inflate(R.layout.lista_canali, container,false);
//Titolo Fragment
((MainActivity) getActivity()).setActionBarTitle("Lista Canali");
//FindViewById
tabLayout = (TabLayout) v.findViewById(R.id.tabs);
viewPager = (ViewPager) v.findViewById(R.id.viewpager);
//Funzioni Tab
viewPager.setAdapter(new MyAdapter(getChildFragmentManager()));
tabLayout.post(new Runnable() {
@Override
public void run() {
tabLayout.setupWithViewPager(viewPager);
}
});
return v;
}
//Adattatore Tab
class MyAdapter extends FragmentPagerAdapter {
public MyAdapter(FragmentManager fm) {
super(fm);
}
@Override
public Fragment getItem(int position)
{
switch (position){
case 0 : return new FragmentCanali();
case 1 : return new FragmentPreferiti();
}
return null;
}
public int getCount() {
return int_items;
}
public CharSequence getPageTitle(int position) {
switch (position){
case 0 :
return "Tutti";
case 1 :
return "Preferiti";
}
return null;
}
我希望我的应用在滑动和点击选项卡标题时可以刷新片段,因为这目前无法实现。希望你们能帮助我。
getChildFragmentManager()
。我在我的项目中将getFragmentManager()
替换为了它。 - CoolMind
