android - How to communicate between fragments?

Question

I am developing an Android application. I have a requirement like there is a button in fragment 1, when a user clicks that button result should be displayed in fragment 2. While loading the activity both fragments is attached. Here is my try:

In main activity:

    public void dsp(String str) {
    secondfragment f2=new secondfragment();
    Bundle bundle = new Bundle();
    bundle.putString("edttext", "From Activity");

    f2.setArguments(bundle);
    }

In first fragment:

    public View onCreateView(LayoutInflater inflater, ViewGroup container,
    Bundle savedInstanceState) {
    View v=inflater.inflate(R.layout.fragone, container,false);
    Button btn = (Button) v.findViewById(R.id.button1); 
    btn.setOnClickListener(new OnClickListener() {           
          @Override
          public void onClick(View v) 
          {
              m.dsp("clicked");
          }    
        });
    return v;
}

In second fragment:

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    View v=inflater.inflate(R.layout.fragtwo, container,false);
    tv= (TextView) v.findViewById(R.id.textView1);

    tv.setText(this.getArguments().getString("name"));

    return v;
}

Here you have what the Android Documentation says about Communicating Between Fragments. Here you'll have all the necessary steps to make two or more fragments communicate securely :)
