使用Listview上的OnClick用另一个片段替换片段

Question

public class Fragment_01 extends ListFragment {

String string[]={"Contact 1","Contact 2","Contact 3","Contact 4","Contact 5"};



    public View onCreateView(LayoutInflater inflater, ViewGroup container ,Bundle saveInstanceState) {

        View myview = inflater.inflate(R.layout.fragment_fragment_01, container, false);
        ListView listView= (ListView) myview.findViewById(android.R.id.list);
        ArrayAdapter<String> array = new ArrayAdapter<String>(getActivity(), android.R.layout.simple_list_item_1,string);
        listView.setAdapter(array);
        listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {


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

            FragmentManager fm = getFragmentManager();
            FragmentTransaction ft = fm.beginTransaction();
            Fragment_03 f3 = new Fragment_03();
            ft.replace(R.id.linearLayout2, f3);
            ft.commit();




           }

        });
        return myview;
    }


        }

Answer 1

不要在另一个内部更改片段。在活动中有框架布局。单击列表视图中的项目，通过界面将事件发送到活动，并在活动中替换片段。这是替换碎片的正确方法。

Answer 2

 Fragment_03 f3 = new Fragment_03();
 FragmentManager fragmentManager = ((FragmentActivity) getContext()).getSupportFragmentManager();
 fragmentManager.beginTransaction()
   .replace(R.id.content_frame, new Fragment_03())
   .commit();

Answer 3

//I am using this code without listView and this is working fine then why the other is not working ??

public class Fragment_01 extends Fragment {



   public View onCreateView(LayoutInflater inflater, ViewGroup container ,Bundle saveInstanceState){

    View myview=inflater.inflate(R.layout.activity_fragment_01,container,false);
       Button btn = (Button) myview.findViewById(R.id.button);
       btn.setOnClickListener(new View.OnClickListener() {
           @Override
           public void onClick(View view) {


               FragmentManager fm =getFragmentManager();
               FragmentTransaction ft =fm.beginTransaction();
               Fragment_03 f3 = new Fragment_03();
               ft.replace(R.id.linearLayout2,f3);
               ft.commit();
           }
       });
    return myview;

}

}
