I have 6 fragments fragments for my navigation drawer, one of which contains 2 other fragments which i use for a viewPager. My problem is that when i switch from the fragment containing the viewPager(HomeFragment) to another and switch back, the contents of both Fragments in HomeFragment disappears.
Here's my code
MainActivity.class
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
...
getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container,
new HomeFragment()).commit();
navigationView.setCheckedItem(R.id.nav_home);
...
}
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
switch (item.getItemId()) {
case R.id.nav_home:
getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container,
new HomeFragment()).commit();
toolbar.setTitle("mSeries");
toolbar.setTitleTextColor(getResources().getColor(R.color.colorPrimaryDark));
break;
...
HomeFragment.class
public class HomeFragment extends Fragment {
#Nullable
#Override
public View onCreateView(#NonNull LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
return inflater.inflate(R.layout.fragment_home, container, false);
}
#Override
public void onViewCreated(#NonNull View view, #Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
ViewPager viewPager = view.findViewById(R.id.viewpager);
setupViewPager(viewPager);
TabLayout tabLayout = view.findViewById(R.id.tabs);
tabLayout.setupWithViewPager(viewPager);
}
private void setupViewPager(ViewPager viewPager) {
ViewPagerAdapter adapter = new ViewPagerAdapter(getFragmentManager());
adapter.addFragment(new UpcomingShowsActivity(), "Upcoming episodes");
adapter.addFragment(new UnwatchedEpisodesActivity(), "Unwatched episodes");
viewPager.setAdapter(adapter);
}
class ViewPagerAdapter extends FragmentPagerAdapter {
private final List<Fragment> mFragmentList = new ArrayList<>();
private final List<String> mFragmentTitleList = new ArrayList<>();
ViewPagerAdapter(FragmentManager manager) {
super(manager);
}
#NonNull
#Override
public Fragment getItem(int position) {
return mFragmentList.get(position);
}
#Override
public int getCount() {
return mFragmentList.size();
}
void addFragment(Fragment fragment, String title) {
mFragmentList.add(fragment);
mFragmentTitleList.add(title);
}
#Override
public CharSequence getPageTitle(int position) {
return mFragmentTitleList.get(position);
}
}
}
UpcomingShowsActivity.class
public class UpcomingShowsActivity extends Fragment {
#Nullable
#Override
public View onCreateView(#NonNull LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
return inflater.inflate(R.layout.fragment_upcoming_episodes, container, false);
}
#Override
public void onViewCreated(#NonNull View view, #Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
}
}
I am a newbie in android, if there's a better or more efficient way of achieving this please let me know.
Thanks for your time.
I fixed it myself and I'm posting this in case someone has a similar issue in the future
Because I'm making a fragment in another fragment, I am supposed to use getChildFragmentManager instead of get getFragmentManager in my HomeFragment.class
private void setupViewPager(ViewPager viewPager) {
ViewPagerAdapter adapter = new ViewPagerAdapter(getChildFragmentManager());
adapter.addFragment(new UpcomingShowsActivity(), "Upcoming episodes");
adapter.addFragment(new UnwatchedEpisodesActivity(), "Unwatched episodes");
viewPager.setAdapter(adapter);
}

I am trying to add tabs in a Fragment (for a bottom navigation bar). However, when I run the app, the tabs don't show up at all. Below is an image of the result:
IMAGE
Home.java -> the fragment that should display 2 tabs which includes BlankFragment.java
CategoryAdapater.java -> sets up the tab names and fragments to display in each tab
BlankFragment.java -> an empty fragment that is shown on each tab
How can I get it to work?
Home.java (the fragment that should show the tabs)
public class Home extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View rootView = inflater.inflate(R.layout.fragment_home, container, false);
ViewPager viewPager = rootView.findViewById(R.id.viewpager);
CategoryAdapter adapter = new CategoryAdapter(getChildFragmentManager());
viewPager.setAdapter(adapter);
TabLayout tabLayout = rootView.findViewById(R.id.tabs);
tabLayout.setupWithViewPager(viewPager);
return rootView;
}
public Home() {}

super(fm);
}
#Override
public Fragment getItem(int position) {
if (position == 0) {
return new BlankFragment();
} else {
return new BlankFragment();
}
}
#Override
public int getCount() {
return 2;
}
#Override
public CharSequence getPageTitle(int position) {
if (position == 0) {
return "Devices";
} else {
return "Numbers";
}
}
}
BlankFragment.java
public class BlankFragment extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View rootView = inflater.inflate(R.layout.fragment_blank, container, false);
return rootView;

Closed 4 years ago.
Today I'm having this issue with my application; I want to say that I read almost ALL the other questions here on StackOverflow but nothing, always the same problem.
homepage.java (main class)
public class homepage extends AppCompatActivity {
private SectionsPagerAdapter mSectionsPagerAdapter;
private ViewPager mViewPager;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_homepage);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager());
mViewPager = (ViewPager) findViewById(R.id.container);
mViewPager.setAdapter(mSectionsPagerAdapter);
TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);
mViewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));

}
return super.onOptionsItemSelected(item);
}
public static class PlaceholderFragment extends Fragment {
private static final String ARG_SECTION_NUMBER = "section_number";
public PlaceholderFragment() {
}
public static PlaceholderFragment newInstance(int sectionNumber) {

fragment.setArguments(args);
return fragment;
}
#Override

}
}
MyAdapter.java (default code from Android Studio Guide)
public class MyAdapter extends RecyclerView.Adapter<MyAdapter.MyViewHolder>
{
private String[] mDataset;
public static class MyViewHolder extends RecyclerView.ViewHolder {
public TextView mTextView;
public MyViewHolder(TextView v) {
super(v);
mTextView = v;
}
}
public MyAdapter(String[] myDataset) {
mDataset = myDataset;
}
#Override
public MyAdapter.MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
TextView v = (TextView) LayoutInflater.from(parent.getContext()).inflate(android.R.layout.simple_list_item_1, parent, false);
MyViewHolder vh = new MyViewHolder(v);
return vh;
}
#Override
public void onBindViewHolder(MyViewHolder holder, int position) {
holder.mTextView.setText(mDataset[position]);
}
#Override
public int getItemCount() {
return mDataset.length;
}
}
And finally, one of the fragment that I'm using:
fibra.java
public class fibra extends Fragment {
private static final String ARG_PARAM1 = "param1";
private static final String ARG_PARAM2 = "param2";
private String mParam1;
private String mParam2;
private OnFragmentInteractionListener mListener;
private RecyclerView recyclerView;
private MyAdapter adapter;
private LinearLayoutManager llm;
String [] prova={"prova1","prova2","prova2","prova2","prova2","prova2","prova2"};
public fibra() {
}
public static fibra newInstance(String param1, String param2) {
fibra fragment = new fibra();
Bundle args = new Bundle();
args.putString(ARG_PARAM1, param1);
args.putString(ARG_PARAM2, param2);
fragment.setArguments(args);
return fragment;
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//setContentView(R.layout.my_activity); (doesn't work "cannot resolve method")
recyclerView.setHasFixedSize(true); //per migliorare performance
llm = new LinearLayoutManager(getActivity());
llm.setOrientation(LinearLayoutManager.VERTICAL);
recyclerView.setLayoutManager(llm);
adapter = new MyAdapter(prova);
recyclerView.setAdapter(adapter);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_fibra, container, false);
return rootView;
}
// TODO: Rename method, update argument and hook method into UI event
public void onButtonPressed(Uri uri) {
if (mListener != null) {
mListener.onFragmentInteraction(uri);
}
}
#Override
public void onAttach(Context context) {
super.onAttach(context);
if (context instanceof OnFragmentInteractionListener) {
mListener = (OnFragmentInteractionListener) context;
} else {
throw new RuntimeException(context.toString()
+ " must implement OnFragmentInteractionListener");
}
}
#Override
public void onDetach() {
super.onDetach();
mListener = null;
}
public interface OnFragmentInteractionListener {
void onFragmentInteraction(Uri uri);
}
}
Here:
//setContentView(R.layout.my_activity); (doesn't work "cannot resolve method")
It's like inflating a layout inside an Activity which you already have onCreateView and in a Fragment.
Change the first codes to :
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
Then, initialize RecyclerView inside onCreateView().
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_fibra, container, false);
// Here you should initialize RecyclerView and other widgets by rootView.findViewById and etc
recyclerView = (RecyclerView) rootView.findViewById(R.id.recyclerView);
recyclerView.setHasFixedSize(true); //per migliorare performance
llm = new LinearLayoutManager(getActivity());
llm.setOrientation(LinearLayoutManager.VERTICAL);
recyclerView.setLayoutManager(llm);
adapter = new MyAdapter(prova);
recyclerView.setAdapter(adapter);
return rootView;
}
You forget to add tablaylout.setupWithViewPager(mViewPager); in your homepage.java
i have a Fragment(C) with a ViewPager(Adapter) with 2 Fragments(A/B).
When i call the Fragment once time, they load fine.
But when i call the Fragment(C) the secend time, the Fragment A and B dont call the View onCreateView methode and the isn´t loaded.
The Fragment C is called with Fragmetnmanger:
FragmentC fragment = new FragmentC();
getActivity().getSupportFragmentManager().beginTransaction().replace(R.id.adressenmdf_detail_container, fragment).addToBackStack(null).commit();
Fragment C
public BelegeDetails(){
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.activity_belege_details, container, false);
//TODO Actionbar noch anpassen
//getSupportActionBar().setDisplayHomeAsUpEnabled(true);
viewPager = (ViewPager) rootView.findViewById(R.id.viewpager);
setupViewPager(viewPager);
tabLayout = (TabLayout) rootView.findViewById(R.id.tabs);
tabLayout.setupWithViewPager(viewPager);
setupTabIcons();
The Setups from Fragment C
private void setupViewPager(ViewPager viewPager) {
ViewPagerAdapter adapter = new ViewPagerAdapter(this.getFragmentManager());
adapter.addFragment(new BelegeDetails1(),"Details" );
adapter.addFragment(new BelegeDetailsPos(), "Positionen");
viewPager.setAdapter(adapter);
}
private void setupTabIcons() {
tabLayout.getTabAt(1).setIcon(R.drawable.ic_belege);
}
class ViewPagerAdapter extends FragmentPagerAdapter {
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);
}
}
The Fragment A BelegDetails1 und the Fragment B BelegDetailsPos are normal Fragment Classes like:
public BelegeDetails1() {
// Required empty public constructor
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState.......
try changing this:
ViewPagerAdapter adapter = new ViewPagerAdapter(this.getFragmentManager());
with:
ViewPagerAdapter adapter = new ViewPagerAdapter(getChildFragmentManager());
As you are nesting fragments, you need to use getChildFragmentManager() instead of getFragmentManager()
I am having a rather annoying problem using tabs in android. I am not sure how they work, problem I am having is knowing where to put the logic of my code. say for example on the first tab I wanted to apply a calendar and the second tab upload a file, for example where would I put this logic, I have 3 xml fragments and so far I have been trying to code the logic by the onCreateView. If anyone could explain how tabbed activities work I would be eternally grateful I used the default android set up for a tabbed activity and added 3 fragments.
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
if(getArguments().getInt(ARG_SECTION_NUMBER)==1) {
View rootView = inflater.inflate(R.layout.fragment_message, container, false);
return rootView;
}
else if(getArguments().getInt(ARG_SECTION_NUMBER)==2){
View rootView = inflater.inflate(R.layout.fragment_read, container, false);
TextView textView= (TextView)rootView.findViewById(R.id.textView_two);
textView.setText("Working");
return rootView;
}
else{
View rootView = inflater.inflate(R.layout.fragment_calendar, container, false);
// would I put my logic here?
return rootView;
}
}
}
Update 2
So now I am trying to listen for button presses and show a toast on one of the fragments,the button does not respond and the Toasts do not appear.
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
final View rootView=inflater.inflate(R.layout.fragment_calendar, container, false);
//final ActionBar actionBar = getSupportActionBar();
//actionBar.setDisplayHomeAsUpEnabled(false);
//actionBar.setTitle(null);
//Toast.makeText(getActivity(),"AKHBKH",Toast.LENGTH_LONG).show();
Button button1=(Button)rootView.findViewById(R.id.button_test1);
button1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Log.i("","");
Toast.makeText(getActivity(),"ddfdf",Toast.LENGTH_LONG).show();
}
});
PS I have tried all these on the Toast
getActivity()
getActivity().getApplicationContext()
getBaseContext()
getContext()
You can take three fragments and All the logic you want to implement should be in each of the fragment respectively. Take MainActivity to View all the fragments. Here i'll share my piece of code.
MainActivity
public class MainActivity extends AppCompatActivity {
private Toolbar toolbar;
private TabLayout tabLayout;
private ViewPager viewPager;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
viewPager = (ViewPager) findViewById(R.id.viewpager);
setupViewPager(viewPager);
tabLayout = (TabLayout) findViewById(R.id.tabs);
tabLayout.setupWithViewPager(viewPager);
}
private void setupViewPager(ViewPager viewPager) {
ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
adapter.addFragment(new Admin(), "ADMIN");
adapter.addFragment(new Faculty(), "FACULTY");
adapter.addFragment(new Student(), "STUDENT");
viewPager.setAdapter(adapter);
}
//----------------------------------------------------------------------------------------------
class ViewPagerAdapter extends FragmentPagerAdapter {
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);
}
}
#Override
public void onBackPressed(){
//Do Here what ever you want do on back press;
}
}
I'll share the code of any one of the fragments: Admin
public class Admin extends Fragment {
EditText aid;
EditText apassword;
Button submit1,changepass;
String id = null, pass = null;
String table = null;
public Admin() {
// Required empty public constructor
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
final View rootView=inflater.inflate(R.layout.fragment_admin, container, false);
aid=(EditText)rootView.findViewById(R.id.admin_id);
apassword=(EditText)rootView.findViewById(R.id.admin_password);
changepass=(Button)rootView.findViewById(R.id.changePass);
submit1=(Button)rootView.findViewById(R.id.submit1);
submit1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
submit1();
}
});
changepass.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent in=new Intent(getActivity(),ChangePassword.class);
startActivity(in);
}
});
// Inflate the layout for this fragment
return rootView;
}
//For Admin login Authentication
public void submit1() {
id = aid.getText().toString();
pass = apassword.getText().toString();
Log.d("id", id);
Log.d("pass", pass);
table="admin";
// new ExecuteTask().execute(id, pass, table);
}}
Initially create an activity MainActivity.
You must create 3 fragments.Extend your activity from FragmentActivity and also implement ActionBar.TabListener
Refer this tutorial:
http://www.androidhive.info/2013/10/android-tab-layout-with-swipeable-views-1/
I have viewpager with 3 fragments (same layout - some EditText and Buttons) and I want to dynamically add small fragment above the viewpager fragment, write something in and then hide it.
This is what I tried:
MainActivity.java:
public class MainActivity extends FragmentActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ViewPager pager = (ViewPager) findViewById(R.id.viewPager);
pager.setAdapter(new MyPagerAdapter(getSupportFragmentManager()));
}
private class MyPagerAdapter extends FragmentPagerAdapter {
public MyPagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int pos) {
switch(pos) {
case 0: return MainFragment.newInstance("1");
case 1: return MainFragment.newInstance("2");
case 2: return MainFragment.newInstance("3");
default: return MainFragment.newInstance("");
}
}
#Override
public int getCount() {
return 3;
}
}
}
MainFragment.java:
public class MainFragment extends android.support.v4.app.Fragment {
EditText contentEdit;
String content, ID;
#Override
public void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
ID = getArguments().getString("msg");
}
#Override
public View onCreateView(LayoutInflater inflater, final ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_main, container, false);
contentEdit = (EditText) view.findViewById(R.id.editText);
contentEdit.setOnTouchListener(new OnSwipeTouchListener(getActivity()) {
public void onSwipeBottom() {
final ViewGroup newView = (ViewGroup) LayoutInflater.from(getActivity()).inflate(R.layout.fragment_title, container, false);
newView.findViewById(R.id.delete_button).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
container.removeView(newView);
}
});
container.addView(newView, 0);
}
public boolean onTouch(View v, MotionEvent event) {
return gestureDetector.onTouchEvent(event);
}
});
return view;
}
}
Try to put a frame layout above that viewPager layout BUT set it's visibility to GONE therefore it won't "exist". Now in your pager onItemClick listener for that small fragment you want to show call findViewByID(R.id.YourFrameLayout).setVisibility(View.VISIBLE); and when you want to hide it, well you get the idea. Don't forget to add your fragment to that container, e.g. YourFrameLayout
