I've been trying to get an id from a listview-onclicklistener to three tabbed fragments. The user firstly clicks in myTicketsFragmentand then goes to the detail page which contains 3 swipeable tabs. These views are 'hosted' by one individual activity named TicketActivity. So currently I've succesfully passed data from the fragment to TicketActivity but I cannot go further than that. Been searching for 2 hours now and still no results..
Here's my code:
myTicketsFragment: passing the data in setOnItemClickListener to tab activity
public void onItemClick(AdapterView<?> parentView,
View childView, int position, long id) {
Bundle bundle = new Bundle();
bundle.putInt("ticketId", myTickets.get(position).getId());
Intent ticketDetail = new Intent(getActivity(), TicketActivity.class);
ticketDetail.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
ticketDetail.putExtras(bundle);
startActivity(ticketDetail);
}
TicketActivity: receiving data and passing it through to the 3 tabs
private ViewPager viewPager;
private TicketTabsPagerAdapter mAdapter;
private ActionBar actionBar;
// Tab titles
private String[] tabs = { "Info", "Intern", "Extern" };
public TicketInfoFragment ticketInfoFragment;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.tabs);
// Receive data
Bundle bundle = getIntent().getExtras();
int ticketId = bundle.getInt("ticketId");
// Pass data to fragments
// ...
// Initilization
viewPager = (ViewPager) findViewById(R.id.pager);
actionBar = getActionBar();
mAdapter = new TicketTabsPagerAdapter(getSupportFragmentManager());
viewPager.setAdapter(mAdapter);
actionBar.setHomeButtonEnabled(true);
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
// Adding Tabs
for (String tab_name : tabs) {
actionBar.addTab(actionBar.newTab().setText(tab_name)
.setTabListener(this));
}
/**
* on swiping the viewpager make respective tab selected
* */
viewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
#Override
public void onPageSelected(int position) {
// on changing the page
// make respected tab selected
actionBar.setSelectedNavigationItem(position);
}
#Override
public void onPageScrolled(int arg0, float arg1, int arg2) {
}
#Override
public void onPageScrollStateChanged(int arg0) {
}
});
}
Example of a tab fragment
public class TicketInfoFragment extends Fragment {
TicketFull ticket = new TicketFull();
private DatabaseHelper db;
int ticketId;
String androidId;
String authCode;
String platform_url;
int uId;
#Override
public void onAttach(Activity activity) {
super.onAttach(activity);
db = new DatabaseHelper(getActivity());
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_ticket_info, container, false);
return rootView;
}
}
I would be pleased if anyone could help me out
Thanks in advance
2 quick ways:
use an static method in your activity to retrieve current ticket id
Design and implement an interface and register the fragments as listeners from the activity
First option, In your activity:
private static int ticketId;
public static int getCurrentTicketId(){
return ticketId;
}
and in your fragment you can do:
TickerActivity.getCurrentTicketId();
Second option, Use an interface:
public interface TicketListener{
public void onTicketChanged(int newTicket);
}
and in your activity add:
public List<TicketListener> listeners = new ArrayList<TicketListener>();
public void addListener(TicketListener listener){
listeners.add(listener);
}
and register every fragment as a new listener
YourFragment frag = new YourFragment();
addListener(frag);
and finally when you want to notify the key to the listeners iterate over the list:
for(TicketListener listener : listeners){
listener.onTicketChanged(ticket);
}
You can do in two different ways. The more simple is in your Activity container has to provider a getter for the data that you want to access from the Fragments, so in your fragments has to access to this getter via getActivity to get a reference to the father and the invoke the get method, I mean:
In TicketActivity:
private int ticketId;
#Override
protected void onCreate(Bundle savedInstanceState) {
...
// Receive data
Bundle bundle = getIntent().getExtras();
ticketId = bundle.getInt("ticketId");
...
}
public int getTicketId() {
return ticketId;
}
And in your fragments:
((TicketActivity)getActivity()).getTicketId();
Or a more elegant way, is passing the Bundle via arguments when you initialize your fragments. You will have to do this inside your TicketTabsPagerAdapter class. I mean something like that:
TicketInfoFragment f = new TicketInfoFragment();
f.setArguments(bundle);
To do this last method is better use the Singleton pattern. You can follow the next link: http://developer.android.com/reference/android/app/Fragment.html
public static class DetailsFragment extends Fragment {
/**
* Create a new instance of DetailsFragment, initialized to
* show the text at 'index'.
*/
public static DetailsFragment newInstance(int index) {
DetailsFragment f = new DetailsFragment();
// Supply index input as an argument.
Bundle args = new Bundle();
args.putInt("index", index);
f.setArguments(args);
return f;
}
public int getShownIndex() {
return getArguments().getInt("index", 0);
}
it is very simple. When you will pass a bundle from ActivityA to other ActivityB(with bundle). it will be received by the ActivityB class instead of fragment.
It's simple to implement:
in onResume method of ActivityB ==> receive the bundle and passes attach it to your required fragment. check my code to pass from onresume to Framgent class
String tag = Constants.TAG_Search;
Fragment fragment;
fragment = fragmentManager.findFragmentByTag(tag);
fragmentTransaction.remove(fragment);
Search searchFragment = new Search();
searchFragment.setArguments(Globals.bd);
fragmentTransaction.add(R.id.tab2, searchFragment, tag);
Hope it will help

I have a View pager. The user can choose how many differents pages he can have.
The pages are all the same layout but it will just load different data.
Here is my fragment adapter :
public class FragmentAdapter extends FragmentPagerAdapter
{
private final List<Fragment> lstFragment = new ArrayList<>();
private final List<String> lstTitles = new ArrayList<>();
public FragmentAdapter(FragmentManager fm) {
super(fm);
}
#Override
public Fragment getItem(int i) {
return lstFragment.get(i);
}
#Nullable
#Override
public CharSequence getPageTitle(int position) {
return lstTitles.get(position);
}
#Override
public int getCount() {
return lstTitles.size();
}
public void AddFragment (Fragment fragment , String title)
{
lstFragment.add(fragment);
lstTitles.add(title);
}
}
And here is the code to call the fragment multiple time :
FragAdapter = new FragmentAdapter(getSupportFragmentManager());
viewPager = (ViewPager) findViewById(R.id.main_tabs_pager);
toolbar = (Toolbar) findViewById(R.id.main_page_toolbar);
tabLayout = (TabLayout) findViewById(R.id.main_tabs);
String[] Fragments = {"Frag1", "Frag2", "Frag3", "Frag4"};
for (int i=0; i<Fragments.length; i++)
{
((FragmentAdapter) FragAdapter).AddFragment(new MenuFragment(),Fragments[i]);
}
viewPager.setAdapter(FragAdapter);
tabLayout = (TabLayout) findViewById(R.id.main_tabs);
tabLayout.setupWithViewPager(viewPager);
So it works fine. But the only problem is that I don't know how to know the difference in code between the differents fragments.
Exemple :
The frag1 must load 5 pictures about the sea
The frag2 must load 8 pictures about the sun
How can I tell the fragment what to do? I tried to pass in the constructeur the arguments by exemple
public MenuFragment(int numberofpictures, String picturesthemes)
{
// Required empty public constructor
}
but the constructors must be empty because it is not called again when fragment is destroyed and recreated...
does anyone has an idea? thanks
UPDATE
I don't know if that is the good way but here is the way I did it :
In main activity I created :
for (int i=0; i<Fragments.length; i++)
{
Bundle parameters = new Bundle();
parameters.putInt("myInt", i);
Fragment menuFragment = new MenuFragment();
menuFragment.setArguments(parameters);
((FragmentAdapter) FragAdapter).AddFragment(menuFragment, Fragments[i]);
}
Which give a everyfragment the the int i which is a reference to the title.
Then I simply wrote this function :
public String getName (int i)
{
return Fragments[i];
}
which return the title based on the int that the fragment got thanks to the bundle
Then, In the MenuFragment() I used this :
private void fillinthelist()
{
myInt = getArguments().getInt("myInt");
String test = ((MainActivity) getActivity()).getName(myInt);
ListOfProgrammes.add(new Modele_carte(test));
}
so it gets the int from the bundle and make a like to it thanks to the function in MainActivity
Is it the good way to do it? It seems to work
You can attach a Bundle containing the parameters with setArguments(Bundle) :
Bundle parameters = new Bundle();
parameters.putInt("myInt", <int_value>);
Fragment menuFragment = new MenuFragment();
menuFragment.setArguments(arguments);
((FragmentAdapter) FragAdapter).AddFragment(menuFragment, Fragments[i]);
A common practice is to build and attach the Bundle in a fragment's class static factory method.
The fragment can use getArguments() to retrieve the parameters.
private int myInt;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
myInt = getArguments().getInt("myInt");
}
I'm trying to make an Android app with a tabbed form. One tab for Autonomous, and the other for TeleOp.
The TeleOp tab needs to be able to read data from the Autonomous tab, but I'm having trouble passing data from one to the other, while I'm switching from the first tab to the next.
They're both fragments, with one parent, called the Match Form. I'm not entirely sure what to do, so here is my code:
MatchForm.java
private SectionsPagerAdapter mSectionsPagerAdapter;
private ViewPager mViewPager;
public TabLayout tabLayout;
public static String startingPos;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_match_form);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
// Create the adapter that will return a fragment for each of the three
// primary sections of the activity.
mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager());
// Set up the ViewPager with the sections adapter.
mViewPager = (ViewPager) findViewById(R.id.container);
mViewPager.setAdapter(mSectionsPagerAdapter);
tabLayout = (TabLayout) findViewById(R.id.tabs);
mViewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));
tabLayout.addOnTabSelectedListener(new TabLayout.ViewPagerOnTabSelectedListener(mViewPager));
tabLayout.addOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
#Override
public void onTabSelected(TabLayout.Tab tab) {
}
#Override
public void onTabUnselected(TabLayout.Tab tab) {
}
#Override
public void onTabReselected(TabLayout.Tab tab) {
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_match_form, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}

There are many ways to pass the data.One easy and efficient way to implement.create a public class in your package.In that class declare your values as static.
public class MyDataClass {
public static String value1;
public static String value2;
}
Now you can access these values from anywhere either in the fragment or activity.
you can pass the values like this
MyDataClass myobj=new MyDataClass();
myobj.value1="Hello";
To fetch the value in another class use
String val=myobj.value1;
You can pass the data from Autonomous Fragment to the parent activity first and then pass it to the Teleop Fragment.
You can use Intents for this.
How to pass values between Fragments
Or use a custom listener to notify the other fragment once the data is sent.
1. Do you really need ViewPager here?
ViewPager is needed if you want to display multiple fragments at the same time. On my opinion, the fragments in ViewPager must be equal and independent. If you want to keep communication between Fragments in ViewPager you can:
Use EventBus or LocalBroadcastManager, etc.;
Cache Fragment inside ViewPager in this way
2. Maybe you need flow?
If you want implement some fragment flow, for example "PickGoods" -> "GoodsCheckout", it is better to use fragment transactions and pass arguments with Bundle. For example, pass selected goods ids from "PickGoods" to "GoodsCheckout".
Note. You can't pass really big amount of data. But it is enough for large set of ids.
3. One more solution.
If your flow belongs to separate activity, which is going to be killed, after final action in flow (it is important to avoid memory leaks) you can use ViewModel attached to activity and store data in it. You can get ViewModels attached to activity from its fragments:
ViewModelProviders.of(getActivity()).get(DataViewModel.class);
So I have CustomAdapter which operates on SQLite database and creates and stores server_name, time_stamp id, etc. and I want it when I click it, it passes server_id to activity which operates 2 fragments and both of them need id to refer to to get other items from database.
From other post I learnt i should in onBindViewHolder create intent and put extras but I don't really know how to pass it to fragments.
Here is fragment from ServerAdapter:
#Override
public void onBindViewHolder(MyViewHolder holder, int position) {
Server server = serversList.get(position);
holder.note.setText(server.getNote());
}
Here is the activity which operates fragments:
public class ParentItemListActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_parentitemlist);
ViewPager viewPager = (ViewPager) findViewById(R.id.viewpager);
SimpleFragmentPagerAdapter adapter = new SimpleFragmentPagerAdapter(this, getSupportFragmentManager());
viewPager.setAdapter(adapter);
TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);
tabLayout.setupWithViewPager(viewPager);
}
}
I've used your 1st code and attached it to onClick
start(MainActivity.this, position);
But I'm having problem understanding 2nd part
public class ItemListOwnedFragment extends Fragment {
public ItemListOwnedFragment() {
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.word_list, container, false);
Log.d("ItemListOwnedFragment", "XD " + "here i want server name" );
}
}
Don't really understand how to implement it.
First of all you need to pass data for your hosting Activity, you could insert data inside your intent, e.g.
public static void start(Context context, long id) {
Intent intent = new Intent(context, SomeActivity.class);
intent.putExtra(ID_KEY, id);
context.startActivity(intent);
}
Then when you get your data in Activity you could attach it to each of your fragments in the Bundle, e.g.
public static Fragment newInstance(long id) {
SomeFragment fragment = new SomeFragment();
Bundle args = new Bundle();
args.putLong(ID_KEY_FOR_FRAGMENT, id);
clientsFragment.setArguments(args);
return fragment;
}
Other way how to share business logic across Activity and Fragment is to use Android Architecture Components - you could share you ViewModel across different entities with one context. e.g. get ViewModel in Fragment by Activity's Context. But that should be done if your business logic really could be shared.
I have 2 fragments (tabs) that share some data. When one changes the data, I'd like to have that reflected on the other tab. I researched this on stackOverflow and I think the relevant answer has to do with a .notifyDataSetChanged() call, but I can't make it work. Here's the relevant code...
public class EnterCourseData extends FragmentActivity implements ActionBar.TabListener {
private ViewPager viewPager;
private TabsPagerAdapter mAdapter;
private ActionBar actionBar;
// Tab titles
private String[] tabs = { "Pars", "Handicaps" };
private int courseNumber, teeNumber;
private Tee tee;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_enter_tees);
// Initilization
Intent mIntent = getIntent();
courseNumber = mIntent.getIntExtra("courseNumber",0);
Course course = Global.getCourse(courseNumber);
teeNumber = mIntent.getIntExtra("teeNumber",0);
tee = course.getTee(teeNumber);
viewPager = (ViewPager) findViewById(R.id.pager);
actionBar = getActionBar();
mAdapter = new TabsPagerAdapter(getSupportFragmentManager(), courseNumber, teeNumber);
viewPager.setAdapter(mAdapter);
actionBar.setHomeButtonEnabled(false);
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
// Adding Tabs
for (String tab_name : tabs) {
actionBar.addTab(actionBar.newTab().setText(tab_name)
.setTabListener(this));
}
/**
* on swiping the viewpager make respective tab selected
* */
viewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
#Override
public void onPageSelected(int position) {
// on changing the page
// make respected tab selected
actionBar.setSelectedNavigationItem(position);
}
#Override
public void onPageScrolled(int arg0, float arg1, int arg2) {
}
#Override
public void onPageScrollStateChanged(int arg0) {
}
});
}
and further down, here is the onClick method that necessitates the refresh...
public void savePars(View view){
tee.setSlope(Integer.parseInt(((EditText) findViewById(R.id.enter_tee_slope)).getText().toString()));
tee.setRating(Double.parseDouble(((EditText) findViewById(R.id.enter_tee_rating)).getText().toString()));
mAdapter.notifyDataSetChanged();
}
Here is the TabsPagerAdapter...
public class TabsPagerAdapter extends FragmentPagerAdapter {
int courseNumber, teeNumber;
public TabsPagerAdapter(FragmentManager fm, int courseNumber, int teeNumber) {
super(fm);
this.courseNumber = courseNumber;
this.teeNumber = teeNumber;
}
#Override
public Fragment getItem(int index) {
switch (index) {
case 0:
// Par Entry activity
Fragment parFragment = new ParFragment();
Bundle args = new Bundle();
args.putInt(ParFragment.ARG_COURSE_NUMBER, courseNumber);
args.putInt(ParFragment.ARG_TEE_NUMBER, teeNumber);
parFragment.setArguments(args);
return parFragment;
case 1:
// Handicap Entry fragment activity
Fragment hcpFragment = new HandicapFragment();
args = new Bundle();
args.putInt(HandicapFragment.ARG_COURSE_NUMBER, courseNumber);
args.putInt(HandicapFragment.ARG_TEE_NUMBER, teeNumber);
hcpFragment.setArguments(args);
return hcpFragment;
}
return null;
}
#Override
public int getCount() {
// get item count - equal to number of tabs
return 2;
}
}
Here is one Fragment...
public class ParFragment extends Fragment {
public static final String ARG_COURSE_NUMBER = "courseNumber", ARG_TEE_NUMBER = "teeNumber";
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_par, container, false);
Bundle args = getArguments();
Course course = Global.getCourse(args.getInt(ARG_COURSE_NUMBER));
((TextView) rootView.findViewById(R.id.display_course_name)).setText(course.getName());
Tee tee = course.getTee(args.getInt(ARG_TEE_NUMBER));
((TextView) rootView.findViewById(R.id.display_tee_name)).setText(tee.getTeeName());
((TextView) rootView.findViewById(R.id.enter_tee_slope)).setText(Integer.toString(tee.getSlope()));
((TextView) rootView.findViewById(R.id.enter_tee_rating)).setText(Double.toString(tee.getRating()));
return rootView;
}
}
And here is the other...
public class HandicapFragment extends Fragment {
public static final String ARG_COURSE_NUMBER = "courseNumber", ARG_TEE_NUMBER = "teeNumber";
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_handicap, container, false);
Bundle args = getArguments();
Course course = Global.getCourse(args.getInt(ARG_COURSE_NUMBER));
((TextView) rootView.findViewById(R.id.display_course_name)).setText(course.getName());
Tee tee = course.getTee(args.getInt(ARG_TEE_NUMBER));
((TextView) rootView.findViewById(R.id.display_tee_name)).setText(tee.getTeeName());
((TextView) rootView.findViewById(R.id.enter_tee_slope)).setText(Integer.toString(tee.getSlope()));
((TextView) rootView.findViewById(R.id.enter_tee_rating)).setText(Double.toString(tee.getRating()));
return rootView;
}
}
When the button is clicked, I want to save the values and I want these values to show up on the other fragment.
Help a noob out.
Thanks
You need to communicate between fragments, but a fragment cannot directly communicate with other fragment, all the communication should be done through the activity which holds these fragments.
The steps to follow are :
Define an Interface in the fragment where you have implemented the onClickListener (let it be Fragment A)
Implement the Interface in the activity which holds these fragments
In the method overridden, retrieve the fragment instance from the viewpager adapter and deliver a message to Fragment B by calling it's public methods.
refer this answer to retrieve fragment instance from adapter
For more details about Communicating with Other Fragments, refer here
So there is a trick: just let the fragments have the object reference of one another and call the other's function to load data when you handle the onClickListener of the button.
E.g:
protected void onClickListener(View view) {
if (view == myButton) {
// Do other stuffs here
fragment1.reloadData();
}
}
P/S : I re-post this as answer to have the code formatter.
I have created a FragmentActivity of 2 tabs. This is a very basic Tab example from Android Developer tutorial using FragmentActivity and FragmentPagerAdapter Code Here
public class FragmentPagerSupport extends FragmentActivity implements
ActionBar.TabListener {
SectionsPagerAdapter mSectionsPagerAdapter;
static final int NUM_ITEMS = 10;
ViewPager mViewPager;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.fragment_pager);
final ActionBar actionBar = getActionBar();
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
...........
}
#Override
public Fragment getItem(int position) {
Fragment fragment = null;
Bundle args = new Bundle();
switch (position) {
case 0:
fragment = new Fragment01();
args.putInt(Fragment01.ARG_SECTION_NUMBER, position + 1);
fragment.setArguments(args);
break;
case 1:
fragment = new Fragment02();
args.putInt(Fragment02.ARG_SECTION_NUMBER, position + 1);
fragment.setArguments(args);
break;
return fragment;
}
}
Then I have created 2 different fragments for 2 tabs:
public static class Fragment01 extends Fragment {
private EditText mName;
private EditText mEmail1;
public static final String ARG_SECTION_NUMBER = "2";
public Fragment01() {
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.activity_customer_add, container, false);
mName = (EditText) v.findViewById(R.id.customer_add_name);
mEmail = (EditText) v.findViewById(R.id.customer_add_email);
View confirmButton = v.findViewById(R.id.customer_add_button);
confirmButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
......................
}
});
}
}
Now in the 2nd tab I need to show the input value of Name and Email from 1st tab and on confirm from 2nd tab need to save in database. But here I stuck. I am not getting an idea how I can keep data from first tab? Please help.
One approach could be to use Singleton DP. There will be only one object having Name, Email etc. as fields. Set Name and Email fields using setters when you are in first fragment and access them using getters in second fragment.
On confirm, you can insert entire object into database.
