XML : Unable to start fragment from onListItemClick

I'm trying to start a fragment from OnItemClickListener event of list view but its not showing anything. to check if the OnItemClickListener is functional or not, I've included a Toast to show some text and its working fine. Here is my code

Here is the code for ItemClickListener of main activity

          listView.setOnItemClickListener(new AdapterView.OnItemClickListener(){          public void onItemClick(AdapterView<?> parent, View view, int position, long id){                Fragment fragment = new Friendtilefragment();              FragmentTransaction transaction = getFragmentManager().beginTransaction();              transaction.replace(R.id.friendtilefragment, fragment);              transaction.addToBackStack(null);              transaction.commit();                Toast.makeText(getApplicationContext(), "An item of the ListView is clicked.", Toast.LENGTH_LONG).show();          }      });    

Code for the Friendtilefragment

  package com.example.xxxxxxxx.socialoid;    import android.app.Fragment;  import android.os.Bundle;  import android.view.LayoutInflater;  import android.view.View;  import android.view.ViewGroup;    public class Friendtilefragment extends Fragment {    @Override  public View onCreateView(LayoutInflater inflater,ViewGroup container, Bundle savedInstanceState) {      return inflater.inflate(R.layout.friendtilefragment_layout, container, false);  }  }
