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

categorylist.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @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;
}

Solution

  • 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.
