How can I send information from my searchview in my main actiity to one of the fragments from my viewpager

Question

My main activity has a viewpager with 3 fragments. In fragment1 I have a recyclerview that shows some information. Back into my main activity I have a searchview, my question is how can I pass the information from my mainactivity to the fragment1 so I can update my recyclerview based on what the user put in the searchview.

I already have the searchview and the listener with onQueryTextSubmit and onQueryTextChange methods to get the string from the searchview

Thank you.

You can use the FragmentPagerAdapter as a bridge. Add a method to your FragmentPagerAdapter:

public void onQueryTextChange(String text) {
    fragment1.onQueryTextChange(String text);
}

In fragment1 you should also add a method:

public void onQueryTextChange(String text) {
    //do something
}

Then in your Activity, when search text changed, call:

theAdapter.onQueryTextChange(text);
