How to refresh previous fragment after closing an activity who was started inside an Adapter?

Question

I have a fragment (FragmentA) with a RecyclerView displaying some CardViews. I wanted to make the cardviews clickable , so the solution I found for this was to implement View.OnClickListener in the ViewHolder inside de adapter class. Something like this:

fragmentAAdapter.java

public class fragmentAViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {       

    public fragmentAViewHolder (View itemView) {
        super(itemView);            

        itemView.setOnClickListener(this);
    }     

    @Override
    public void onClick(View v) {
        //do something..
    }
}

The onClick() method gets the data from the clicked cardview and start an activity (InfoActivity) who displays the data.

OnClick() method

@Override
    public void onClick(View v) {            
        Intent intent = new Intent(itemView.getContext(), InfoActivity.class);

        Bundle mBundle = new Bundle();
        mBundle.putParcelable("someData", someData);
        intent.putExtras(mBundle);            
        itemView.getContext().startActivity(intent);
    }

In the InfoActivity I can update and delete the data. After that I want to finish the InfoActivity and refresh the FragmentA to get the new data.

To close the activity and refresh the previous fragment I am trying to use the startActivityForResult(). Like this:

@Override
    public void onClick(View v) {            
        Intent intent = new Intent(itemView.getContext(), InfoActivity.class);       

        ((Activity)  itemView.getContext()).startActivityForResult(intent, 10001);

    }

InfoActivity.java

@Override
    public void onClick(DialogInterface dialog, int which) {        
    setResult(InfoActivity.RESULT_OK);
    finish();
}

FragmentA.java

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data)
{
    super.onActivityResult(requestCode, resultCode, data);
    if ((requestCode == 10001) && (resultCode == InfoActivity.RESULT_OK)) {

        FragmentAfragment  = new FragmentA();
        android.support.v4.app.FragmentTransaction fragmentTransaction =
                getFragmentManager().beginTransaction();
        fragmentTransaction.replace(R.id.fragment_container, fragment);
        fragmentTransaction.commit();
    }
}

But when I close the InfoActivity nothing happens.

The problem is that the setResult(InfoActivity.RESULT_OK) returns the result to the adapter class (fragmentAAdapter) not to FragmentA, so the method onActivityResult() in FragmentA is never called.

How do I refresh the FragmentA after close InfoActivity who was started inside the onClick() method in the fragmentAAdapter??

Update - Solution

I overwrote the method onActivityResult() in the activity of the FragmentA. Like this:

MainActivity.java

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {

    super.onActivityResult(requestCode, resultCode, data);
    if ((requestCode == 10001) && (resultCode == 10001)) {

        FragmentA fragment  = new FragmentA();
        android.support.v4.app.FragmentTransaction fragmentTransaction =
                getSupportFragmentManager().beginTransaction();
        fragmentTransaction.replace(R.id.fragment_container, fragment);
        fragmentTransaction.commit();
    }
}

and in InfoActivity.java:

@Override
public void onClick(DialogInterface dialog, int which) {        
    setResult(10001);
    finish();
}

Every time it closes an activity and go back to the FragmentA the onActivityResult() in the MainActivity is called, and when the condition if((requestCode == 10001) && (resultCode == 10001)) is true the FragmentA is refreshed.

In the activity of your fragment you can do something like this:

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    requestCode &= 0xffff;
    for (Fragment fragment : getSupportFragmentManager().getFragments()) {
        if (fragment != null) {
            fragment.onActivityResult(requestCode, resultCode, data);
        }
    }
    super.onActivityResult(requestCode, resultCode, data);
}

Or you can use a Event bus like: http://square.github.io/otto/
