How to pass data from a fragment to a dialogFragme

Question

I know that this was asked before, but I dont quite understand how to implement it. I have a fragment "myFragment" in which I create an object of a "myDialogueFragment". I want to pass some value to the myDialogueFragment when I invoke it from the myFragment. I have an integer num, that I want to pass to the myDialogueFragment and store that number in a local database along with some other info from the myDialogueFragment.

I might be mistaken, but all the code I have seen is about sending data from the myDialogueFragment back to the myFragment which is not what I really want.

static MyDialogFragment newInstance(int num) {

MyDialogFragment f = new MyDialogFragment();

// Supply num input as an argument.
Bundle args = new Bundle();
args.putInt("num", num);
f.setArguments(args);

return f;
}  

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    mNum = getArguments().getInt("num");
    ...
}

So, this code gets the arguments within the myFragment onCreate() method. I want to sent the arguments within the myFragment() and receive them in the myDialogueFragment.

How can I achieve that?

Answer 1

What you need is to setArguments on the fragment as follows:

Bundle args = new Bundle();
args.putString("key", "value");
DialogFragment newFragment = new YourDialogFragment();  
newFragment.setArguments(args);
newFragment.show(getSupportFragmentManager(), "TAG");

All you have to do now, is catch those arguments in your fragment and use them...

AND IN THE DIALOG FRAGMENT YOU READ IT LIKE THIS...

Bundle mArgs = getArguments();
String myValue = mArgs.getString("keyUsed to send it...");

I call a FragmentDialog inside a calsswhich exdented to ActivityFragment

//TODO 1
                Followers clickedObj = (Followers) 

                parent.getItemAtPosition(position);
                Bundle bundle = new Bundle();
                bundle.putString("name", clickedObj.getFollow_name());
                bundle.putString("nick", clickedObj.getFollow_nickname());
                bundle.putString("score", clickedObj.getFollow_score());
                bundle.putString("title", clickedObj.getFollow_title());
                FragmentManager fragmentManager = getSupportFragmentManager();
                UserPopUp userPopUp = new UserPopUp();
                //TODO 1
                userPopUp.setArguments(bundle);
                userPopUp.show(fragmentManager, "followers");

and I called it on onActivityCreated in my class which extended to DialogFragment

@Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);

        //Bundle Data Cekme başlangıç
        Bundle mArgs = getArguments();
        String userName = mArgs.getString("name");
        String userNickName = mArgs.getString("nick");
        String userTitle = mArgs.getString("title");
        String userScore = mArgs.getString("score");
        user_name.setText(userName);
        nick_name.setText(userNickName);
        challenge_title.setText(userTitle);
        user_score.setText(userScore);
        // bitiş

    }

works pretty good
