我已经尝试了所有可能的情况但没有解决,需要建议

public class WolfActivity extends ActionBarActivity {

   EditText fname_ele,lname_ele,email_ele,phone_ele,pwd_ele,fax_ele,addr_ele,addr1_ele,city_ele,zipcode_ele,facility_ele,state_ele;

    String fname,lname,email,phone,pwd,fax,addr,addr1,city,zipcode,facility,state;
    Button button;
    AlertDialog alertDialog;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        fname_ele=(EditText) findViewById(R.id.first_name);
        lname_ele=(EditText) findViewById(R.id.last_name);
        email_ele=(EditText) findViewById(R.id.email);
        button=(Button) findViewById(R.id.submit_button);
        phone_ele=(EditText) findViewById(R.id.phone);
        addr_ele=(EditText) findViewById(R.id.address);
        addr1_ele=(EditText) findViewById(R.id.address1);
        fax_ele=(EditText) findViewById(R.id.fax);
        facility_ele=(EditText) findViewById(R.id.facility);
        zipcode_ele=(EditText) findViewById(R.id.zip);
        city_ele=(EditText) findViewById(R.id.city);
        state_ele=(EditText) findViewById(R.id.state);

    /* Spinner dropdown = (Spinner)findViewById(R.id.state);
        String[] items = new String[]{"1", "2", "3" };
        ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, items);
        dropdown.setAdapter(adapter);*/

        button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            fname=fname_ele.getText().toString();
            lname=lname_ele.getText().toString();
            email=email_ele.getText().toString(); …

我volley jar用来创建customListView下面是我用来实现的代码.我已经公开了.

public View onCreateView(LayoutInflater inflater, ViewGroup container,
                Bundle savedInstanceState) {
            View rootView = inflater.inflate(R.layout.fragment_inventory, container, false);

            button=(Button)rootView.findViewById(R.id.button);
            button.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {
                    displayView(7);
                    //launchQRScanner(view);
                }
            });

            listView = (ListView) rootView.findViewById(R.id.list);
            adapter = new CustomListAdapter(getActivity(), inventoryList);
            listView.setAdapter(adapter);
            pDialog = new ProgressDialog(getActivity());
            // Showing progress dialog before making http request
            pDialog.setMessage("Loading...");
            pDialog.show();

            Log.d("Url: ",url);

            // Creating volley request obj
            JsonArrayRequest inventoryReq = new JsonArrayRequest(url,new Response.Listener<JSONArray>() {
                        @Override
                        public void onResponse(JSONArray response) …
