You can do something like below,
String cid=id.getText().toString();
Fragment fr=new friendfragment();
FragmentManager fm=getFragmentManager();
android.app.FragmentTransaction ft=fm.beginTransaction();
Bundle args = new Bundle();
args.putString("CID", cid);
fr.setArguments(args);
ft.replace(R.id.content_frame, fr);
ft.commit();
To receive the data do the following,
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
String strtext = getArguments().getString("CID");
return inflater.inflate(R.layout.fragment, container, false);
}
