    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState){
        myFragmentView = inflater.inflate(R.layout.fragment_search, container, false);
        ed = (SearchView) getActivity().findViewById(R.id.textSearch);
        sc = (ImageButton) getActivity().findViewById(R.id.scanCamera);
        hom = (ImageButton) getActivity().findViewById(R.id.btnhome);
        lv = (ListView) myFragmentView.findViewById(R.id.resultList);
        if(getArguments() !=null) {
            word = this.getArguments().getString("word");
        }

        new GetResult().execute();

        lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {

试试这段代码。

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

        String selected1 = ((TextView) view.findViewById(R.id.name)).getText().toString();

                    Toast toast1 = Toast.makeText(getApplicationContext(), selected1, Toast.LENGTH_SHORT);
                    toast1.show();
                Intent intent = new Intent(getActivity(), MainActivity.class);
                intent.putExtra("word", noreg);
                startActivity(intent);
            }
        });
