I have a ViewPager activity which will contain different fragments
I want to pass data from Fragment 1 to Fragment 2, Fragment 2 to Fragment 3, and so forth
Now I understand there is a way to do it by sending data back to the Activity and then passing it onto the next fragment by making a custom interface in the fragment and implementing them on the activity, but is there a way to do it so that the data is passed directly?
Thanks a bunch!

I have a main fragment that contains a viewpager. This viewpager gets the same secondary fragment (different from the main one) but with different parameters every time. Inside the said secondary fragment that is inside the viewpager, i have a recyclerview. Inside these recyclerviews are some fields that the user fills up. When the main fragment (the one that holds the viewpager) is closed (via a button click) i need to get the data from each recyclerview. How do i to that?
The best way to solve this problem is that implement interface which will give call back to activity holding these fragment and then from Activity pass it to fragment(main) and then use viewpager to get Fragment(secondry) and pass data.
Steps one would be implent interface which will give callback to activity and the get fragment from viewpager(Link for same)
I am having the following problem, my application has two fragments, one with a Spinner where it contains the contents of the ArrayList and another fragment containing a ListView, I want to pass the contents of the Spinner ArrayList to the Activity to send it to the other fragment, I am doing so because I'm using a BottomNavigationView. Any idea how to do it?
your Fragments have context. This context could be casted to your Activity.
in Fragment
((YourActivity) getContext()).send(contents);
I am trying to implement 10 fragments in single activity each fragment have a single button and occupy whole screen, when button is pressed fragment is change to another fragment to do this i make interface in Fragment1 called OnFragmentChangeListener which have changefragment() method i implement OnFragmentChangeListener interface in main activity and define changeFragment().
My program sucessfully transaction from fragment 1 to fragment 2 but i can't able to implement this for 10 fragment.
Basically I am trying to create an app that passes data filled in an EditText on on one fragment, into a TextView on another fragment on a button click(The buttons is in the first fragment with the EditText). I use the SlidingTabLayout. I have 2 java classes that both extend Fragment and both inflate separate xml layouts(in the onCreateView). I have a java MainActivty with a public class"SectionsPagerAdapter that extends FragmentPagerAdapter, which depending on the swipe of the user displays 1 of the 2 Fragment classes. I am really confused on how I can send data between the 2 fragment sot that from the EditText in 1 fragment can get sent to the TextView in the other fragment on a button click. Could the suggested solutions be explained as simple as possible because I am relatively new to Android Studio. Many thanks in advance.
As per my understanding, basically you want to pass data between two fragments.
You can use activity for that from where fragments are initialized.
you can do this.
in MainActivity.java:
have a function setData(Object obj) and getData() which returns that object.
From fragment:
You can call those function of activity to save your data and get your data.
Here's way:
MainActivity activity = (MainActivity) getActivity();
Object obj = activity.getData();
activity.setData(obj);
I hope it helps.
I have the following situation: I open the Fragment A and goals, through a click event of the button, go to the Fragment B. When I am in Fragment B and hit the back button (in order to return to the Fragment A) I would like to pass some parameters to Fragment A. Does anyone know how I can do this?
Thank you in advance to all.
Your activity can implement a custom listener interface on the Activity and use a reference to it in your fragment to pass the communication back.
You can send a broadcast when you hit the back button in Fragment B to Fragment A with the parameters you need put in the bundle, and have broadcast receiver on the Fragment A.
Hope this helps!
