How to pass a string between fragments in a viewpager

Question

I\'m trying to pass a string between two fragments in a viewpager but I didn\'t found the right way to do it. Here is my code so far :

public class MyFragmentPag         


        

Answer 1

You're obviously using ViewPager and you can take advantage of it. You can add a tag to a ViewPager like this:

Activity:

pager.setTag("some text");  // pager is a ViewPager object

Then you can get this data via ViewGroup in a fragment like this:

Fragment:

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View view =  inflater.inflate(R.layout.fragment_main, container, false);

    String result = container.getTag().toString();
    // do something with the result

    return view;

You can also setTag() to the container in the fragment.

This is the cleanest solution I found for sending data among fragments and their mother activity. Another solution (not mentioned here so far) is sending data through SharedPreferences, but I would suggest using tags if possible.

Answer 2

So i found the solution, the implementation is correct, the only thing that I should do the treatement I want in the method on the second fragment and that's it !
