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

I just created my first Android app through Android Studio using Java. I am working with two fragments in the process. The first fragment consists of a gridview with cards. When you click on a card you get to the Second Fragment. So far everything works. My problem is that when returning from the Second Fragment to the First Fragment (CategoryFragment) via the AppBar, the content remains empty. It seems that the method onCreateView is not executed again. What did I do wrong? Did I not understand something correctly?
public class CategoryFragment extends Fragment implements CardViewAdapter.ItemClickListener{
private RecyclerView recyclerView;
private CategoriesService categoriesData;
private SharedPreferences sharedPreferences;
private RequestQueue queue;
private FragmentCategoryBinding binding;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
sharedPreferences = this.getActivity().getSharedPreferences("SPOTIFY", 0);
queue = Volley.newRequestQueue(this.getActivity());
Toast.makeText(this.getContext(), "categoryFragment loaded" ,Toast.LENGTH_LONG).show();
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
super.onCreateView(inflater, container, savedInstanceState);
View view = inflater.inflate(R.layout.fragment_category, container, false);
categoriesData = new CategoriesService( view.getContext(), this.queue, this.sharedPreferences);
categoriesData.loadData();
CardViewAdapter mAdapter = new CardViewAdapter(view.getContext(), categoriesData.getCategories());
mAdapter.setClickListener(this);
recyclerView = view.findViewById(R.id.categoriesGrid);
recyclerView.setLayoutManager(new GridLayoutManager(view.getContext(), 6));
recyclerView.setAdapter(mAdapter);
return view;
/*
binding = FragmentCategoryBinding.inflate(inflater, container, false);
return binding.getRoot();
*/
}
public void onViewCreated(#NonNull View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
/*
binding.buttonFirst.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
NavHostFragment.findNavController(CategoryFragment.this)
.navigate(R.id.action_FirstFragment_to_SecondFragment);
}
});
*/
}
#Override
public void onItemClick(View view, int pos) {
SpotifyCategoryCard item = categoriesData.getCategory(pos);
Toast.makeText(getContext(), "Click on '"+ item.getTitle() +"' (Type: '"+item.type+"')" ,Toast.LENGTH_SHORT).show();
NavHostFragment.findNavController(CategoryFragment.this)
.navigate(R.id.action_FirstFragment_to_SecondFragment);
}
#Override
public void onDestroyView() {
super.onDestroyView();
binding = null;
}
}
I have one app that have 2 tabs:
PESQUISA (Filter)
SEUS FAVORITOS (Your Favorite).
The "PESQUISA" tab: this tab has some card views.
The "SEUS FAVORITOS" tab: this tab has a listview.
Whenever I click in one card into "PESQUISA" tab I would like that add the information about card into listview, but I don't know how to update the listview in "SEUS FAVORITOS" tab.
Actually, the listview is updated when I close and open app again.
I tried search some examples in stack-overflow, google, but I cannot find.
MY ACTIVITY
public class FiltersActivity extends AppCompatActivity {
private CellPhone cellPhone;
private FavoriteFragment favoriteFragment;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_filters);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
toolbar.setTitle(R.string.app_name);
setSupportActionBar(toolbar);
final ViewPager viewPager = (ViewPager) findViewById(R.id.view_pager);
List<String> titles = new ArrayList<>();
titles.add(getString(R.string.search));
titles.add(getString(R.string.your_favorite));
cellPhone = getIntent().getParcelableExtra("currentCellPhone");
final FiltersViewPagerAdapter mainViewPagerAdapter = new FiltersViewPagerAdapter(getSupportFragmentManager(), titles, cellPhone);
viewPager.setAdapter(mainViewPagerAdapter);
TabLayout tabLayout = (TabLayout) findViewById(R.id.tab_layout);
tabLayout.setupWithViewPager(viewPager);
}
}
MY FAVORITE Fragment
public class FavoriteFragment extends Fragment {
private RecyclerView mRecycleView;
private CellPhoneFavoriteListAdapter mAdapter;
private List<CellPhone> cellPhoneList;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_favorite, container, false);
mRecycleView = (RecyclerView) view.findViewById(R.id.recycler_view_result_phones);
mRecycleView.setHasFixedSize(true);
RecyclerView.LayoutManager layoutManager = new StaggeredGridLayoutManager(2, StaggeredGridLayoutManager.VERTICAL);
mRecycleView.setLayoutManager(layoutManager);
DatabaseSQLiteService dao = new DatabaseSQLiteService(view.getContext());
cellPhoneList = dao.getAllFavoriteCellphone();
mAdapter = new CellPhoneFavoriteListAdapter(view.getContext(), cellPhoneList);
mRecycleView.setAdapter(mAdapter);
return view;
}
}
MY FragmentPagerAdapter
public class FiltersViewPagerAdapter extends FragmentPagerAdapter {
private List<String> mFragmentTitleList = new ArrayList<>();
private FragmentManager mFragmentManager;
private CellPhone cellPhone;
public FiltersViewPagerAdapter(FragmentManager fm, List<String> titles, CellPhone cellPhone) {
super(fm);
mFragmentManager = fm;
this.mFragmentTitleList = titles;
this.cellPhone = cellPhone;
}
#Override
public Fragment getItem(int position) {
Fragment fragment;
if (position == 0) {
fragment = new FiltersFragment();
Bundle bundle = new Bundle();
bundle.putParcelable("currentCellPhone", cellPhone);
fragment.setArguments(bundle);
} else {
fragment = new FavoriteFragment();
Bundle bundle = new Bundle();
bundle.putInt("tipo", position);
fragment.setArguments(bundle);
}
return fragment;
}
#Override
public int getCount() {
return 2;
}
#Override
public CharSequence getPageTitle(int position) {
return mFragmentTitleList.get(position);
}
}
My sugestion is to replace the List<String> titles, which is local to onCreate(), by a member variable List<TitleItem> which could be accessed by any of the fragments using a callback on the Activity. (The callback can be done by casting getActivity() to FiltersActivity in the Fragment, or by defining an interface and having FiltersActivity implement it.
On another side, TitleItem, would have the title String, and the state which would indicate if it is a favourite or not.
When a title is selected from PESQUIZA, it would the change the item's state (in the list). When the user switches to SEUS FAVORITOS, the lisview would be repopulated with items with favourite state active.
To repopulate the listview, as a ViewPager is in use, it would have to be done when the fragment becomes visible vs. the loading ahead of time that ViewPager does. To do this override public void setUserVisibleHint(boolean isVisibleToUser) and put the update logic in here.
EDIT I
I had wrongly interpreted the titles list as the list of items that could become favourites. After re-reading the question I see the items are being queried from the internal database.
What you cando is the following:
In the recycler view adapter add these methods:
public void setData(List<CellPhone> data) {
this.data = data;
refreshData();
}
private void refreshData(){
this.notifyDataSetChanged();
}
Note: data is the dataset member variable you defined probably with a different name.
Then in the fragment:
#Override
public void setUserVisibleHint(boolean isVisibleToUser) {
super.setUserVisibleHint(isVisibleToUser);
if (isVisibleToUser) {
// Refresh your fragment here
cellPhoneList = dao.getAllFavoriteCellphone();
mAdapter.setData(cellPhoneList);
}
}
According to Juan help the correctly solution is:
In MY FAVORITE Fragment
public class FavoriteFragment extends Fragment {
private RecyclerView mRecycleView;
private CellPhoneFavoriteListAdapter mAdapter;
private List<CellPhone> cellPhoneList;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_favorite, container, false);
mRecycleView = (RecyclerView) view.findViewById(R.id.recycler_view_result_phones);
mRecycleView.setHasFixedSize(true);
RecyclerView.LayoutManager layoutManager = new StaggeredGridLayoutManager(2, StaggeredGridLayoutManager.VERTICAL);
mRecycleView.setLayoutManager(layoutManager);
DatabaseSQLiteService dao = new DatabaseSQLiteService(view.getContext());
cellPhoneList = dao.getAllFavoriteCellphone();
mAdapter = new CellPhoneFavoriteListAdapter(view.getContext(), cellPhoneList);
mRecycleView.setAdapter(mAdapter);
return view;
}
#Override
public void setUserVisibleHint(boolean isVisibleToUser) {
super.setUserVisibleHint(isVisibleToUser);
if (isVisibleToUser) {
// Update Listview here
DatabaseSQLiteService dao = new DatabaseSQLiteService(getContext());
cellPhoneList = dao.getAllFavoriteCellphone();
mAdapter.setData(cellPhoneList);
}
}
}
and in MY ADAPTER I just add two method
public void setData(List<CellPhone> data) {
this.itemsList = data;
refreshData();
}
private void refreshData(){
this.notifyDataSetChanged();
}
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 have three tabs using the implementation below and they perform very well. When tab is changed the proper fragment is load and so on. The problem is that, when i get to the last tab and comeback to the first fragment, its like its oncreateview method is always triggered again running the other codes it in causing duplicates. Any help will be greatly appreciated.

So when i swipe back here from the last tab. OncreateView runs again. How can i handle that and prevent duplicates. Thank you
By defaults ViewPager retains only 1 page in the view hierarchy in an idle state.So when you swipe to third tab the viepager destroys the first tab in order to retain the second one.
To solve this issue add this line
viewPager.setOffscreenPageLimit(3);
after you set your adapter.
Check here the documentation for more
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
