passing context as argument of DialogFragment

it's possible to pass a context variable to a DialogFragment?

i've use this code inside dialog for passing a string:

public static ConfirmDialog newInstance( String f) {
    ConfirmDialog d = new ConfirmDialog();

    Bundle args = new Bundle();
    args.putString("FILE_NAME", f);
    d.setArguments(args);

    return d;
}

but i don't find any function like putString for passing context. It's possible to do that?

onAttach(Activity activity) is now deprecated,

@Override
public void onAttach(Activity activity) {
    super.onAttach(activity);
}


use onAttach(Context context) instead

@Override
public void onAttach(Context context) {
    super.onAttach(context);
}

use like this:

public class Dialog extends DialogFragment implements OnClickListener {
    public void onClick(View v) {
    switch (v.getId()) {
        case R.id.message: {
            this.startActivity(new Intent(context, Login.class));
                                 //or use getActivity() instead of context
            }
            break;
         }
    }
    @Override
    public void onAttach(Activity activity) {
        // TODO Auto-generated method stub
        super.onAttach(activity);
        context=activity;
    }
}

Your DialogFragment has a very handy method for getting a Context instance:

getActivity()

Fragment#getActivity() will return the instance of the Activity (which is a Context) that the Fragment is attached to. Use it after the Fragment's onAttach() is called. The below chart illustrates the Fragment lifecycle, as you can see, using getActivity() from onCreate() to onDestroy() should be a valid call.

enter image description here

For more information, read the Fragment documentation
