Issue
I have ControllerFragment
which has 3 child fragments. Children fragments change are provided in the tabLayout via ViewPager. Unsend Apple and Banana badge count are computable variable values. unSendAppleCountTxtView
and unSendBananaCountTxtView
are changed according to these variable values.
My function is running main Thread.
Tried methods:
- I have controlled null check and textView isn't null
setUnSendAppleCount
function is taken in these threads (runOnUIThread, new Handler(), new Handler(Looper.getMainLooper()))- I have tried
AsyncTask
and not working setView and setText inpostExecute
too. - And finally I scan all related questions and tried.
All methods didn't work. TextView is empty value.
public class ControllerFragment extends Fragment {
@Override
public View onCreateView(@NonNull LayoutInflater inflater, ViewGroup viewGroup, Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.controller_fragment, viewGroup, false);
tabs = ViewUtil.findById(rootView, R.id.tabs);
viewPager = ViewUtil.findById(rootView, R.id.controllerViewPager);
setFragments();
setupViewPager(viewPager);
tabs.setupWithViewPager(viewPager);
setupTabIcons(viewGroup);
return rootView;
}
private void setupTabIcons(ViewGroup viewGroup) {
LinearLayout appleListTab = (LinearLayout) LayoutInflater.from(MyApplication.getContext()).inflate(R.layout.tab_title_text_and_badge, viewGroup, false);
RelativeLayout pearListTab = (RelativeLayout) LayoutInflater.from(MyApplication.getContext()).inflate(R.layout.tab_title_text, viewGroup, false);
LinearLayout bananaListTab = (LinearLayout) LayoutInflater.from(MyApplication.getContext()).inflate(R.layout.tab_title_text_and_badge, viewGroup, false);
unSendAppleCountTxtView = appleListTab.findViewById(R.id.badgeView);
unSendBananaCountTxtView = bananaListTab.findViewById(R.id.badgeView);
TextView appleTextView = appleListTab.findViewById(R.id.textView);
TextView pearTextView = pearListTab.findViewById(R.id.textView);
TextView bananaTextView = bananaListTab.findViewById(R.id.textView);
setUnSendAppleCount(2); //....this function is not working
setUnSendBananaCount(2); //.....this function is not working
bananaTextView.setText(getString(R.string.bananas));
tabs.getTabAt(0).setCustomView(bananaListTab);
appleTextView.setText(getString(R.string.apples));
tabs.getTabAt(1).setCustomView(appleListTab);
pearTextView.setText(getString(R.string.pears));
tabs.getTabAt(2).setCustomView(pearListTab);
}
private void setupViewPager(ViewPager viewPager) {
TabsViewPagerAdapter adapter = new TabsViewPagerAdapter(getFragmentManager());
adapter.addFrag(bananaFragment, getString(R.string.bananas));
adapter.addFrag(appleFragment, getString(R.string.apples));
adapter.addFrag(pearFragment, getString(R.string.pears));
viewPager.setAdapter(adapter);
viewPager.setCurrentItem(1);
}
private void setUnSendAppleCount(int unSendCount) {
if (unSendAppleCountTxtView != null) {
if (unSendCount > 0) {
unSendAppleCountTxtView.setVisibility(View.VISIBLE);
unSendAppleCountTxtView.setText(String.format(getMyLocale(), "%d", unSendCount));
} else {
unSendAppleCountTxtView.setVisibility(View.GONE);
}
}
}
}

Please help me
Solution
I guess different thread problem. I have tried that eventBus for activity passing data to fragment and it solved.
ControllerFragment(){
@Override
public void onStart() {
super.onStart();
if (!EventBus.getDefault().isRegistered(this)) EventBus.getDefault().register(this);
}
@Override
public void onStop() {
super.onStop();
EventBus.getDefault().unregister(this);
}
@Subscribe(sticky = true, threadMode = ThreadMode.MAIN)
public void onEventMain(ControllerEvent event) {
if (event.getSelectedEventType() == ControllerEvent.tabControllerEventTypes.refreshCount.ordinal()) {
setUnSendAppleCount(event.getAppleCount());
}
}
}
