无法在listview中的Itemclicklistener上打开新片段

Question

我无法使用此代码在listview中的Itemclicklistener上打开一个新片段。我该如何解决这个问题？

ListView listView = (ListView) findViewById(R.id.mobile_list);
  listView.setAdapter(adapter);
  listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
  public void onItemClick(AdapterView<?> parent, View view,
                                        int position, long id) {
   if (position == 0) {

    FragmentManager fm = getSupportFragmentManager();
    menu = new Menu();
    FragmentTransaction ft = fm.beginTransaction();
    ft.add(R.id.frag, menu);
    ft.commit();

下面的代码对我有用。试试吧。如果您需要任何澄清，请询问。

ListView listView = (ListView) findViewById(R.id.mobile_list);

listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {       
                Fragment fr = new Menu2(); // next fragment class name is Menu2. Change it to your next class name
                FragmentManager fm=getFragmentManager();
                android.app.FragmentTransaction ft=fm.beginTransaction();                   
                ft.replace(R.id.content_main, fr); // your main layout id. not next fragment layout.
                ft.addToBackStack(null);
                ft.commit();
            }
        });
