Passing data from listview in fragment to fragment

when i click on the listview the bundle can get the value, but cant pass the value to second fragment.
First Fragment

@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

final String category = ((TextView) view.findViewById(R.id.mainproductitem)).getText().toString();
details_fragment ldf = new details_fragment ();
Bundle args = new Bundle();
args.putString("category", category);
ldf.setArguments(args);
}
});
return view;

}


Second Fragment

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// TODO Auto-generated method stub

view=inflater.inflate(R.layout.my_fragment2, container, false);
test = (TextView)view.findViewById(R.id.textView);

Bundle args = getArguments();
if (args != null && args.containsKey("category")){
String userId = args.getString("category");
test.setText(userId);
}
return view;
}

Answer

HomeActivity.xml

<?xml version="1.0" encoding="utf-8"?>
  <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
   xmlns:app="http://schemas.android.com/apk/res-auto"
   xmlns:tools="http://schemas.android.com/tools"
   android:layout_width="match_parent"
   android:layout_height="match_parent"
   app:layout_behavior="@string/appbar_scrolling_view_behavior"
   tools:context="com.example.activity.HomeActivity"
   tools:showIn="@layout/app_bar_home">

//View that will hold all the fragments
<FrameLayout
    android:id="@+id/container_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
</FrameLayout>

FirstFragment

 @Override
 public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    // Inflate the layout for this fragment

    View view = inflater.inflate(R.layout.fragment1, container, false);
    view.setBackgroundColor(Color.WHITE);

     listViewAdapter.SetOnItemClickListener(new OnItemClickListener() {
                    @Override
                    public void onItemClick(View view, int position) {
                        SecondFragment secondFrag = new SecondFragment();
                        Bundle args = new Bundle();
                        args.putString("Key","some value");

                        secondFrag .setArguments(args);
                        getFragmentManager()
                       .beginTransaction()
                       .replace(R.id.container_view, fragment)
                       .addToBackStack(null)
                       .commit();
                    }
                });
    return view;
}

SecondFragment

public class SecondFragment extends Fragment {

     public SecondFragment() {
    // Required empty public constructor
}

  @Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    // Inflate the layout for this fragment
    View view = inflater.inflate(R.layout.second_fragment, container, false);
    TextView textView = (TextView)view.findViewById(R.id.textView);
    view.setBackgroundColor(Color.WHITE);
    String key = getArguments().getString("Key");
    //Set the value to your text view
     textView.setText(key);
    return view;
}

I tried this out and it works perfectly.
