Fragment中setColorSchemeResource报空指针异常

???????c 2016-12-13 11:35:33

在Fragment中调用srl.setColorSchemeResources(
android.R.color.holo_blue_light,
android.R.color.holo_red_light,
android.R.color.holo_orange_light,
android.R.color.holo_green_light);
代码报错，srl为空，但是前面的View不为空，想了一上午都没找出问题，求大神帮忙解决一下！代码如下，谢谢！

Fragment代码



public class AddressFragment extends Fragment {

    private ListView lv;

    private SwipeRefreshLayout srl;

    private ArrayList<String> datas;

    private ArrayAdapter<String> adapter;

    private void initView(){

        datas=new ArrayList<>();

        datas.add("老干妈鸡蛋炒饭");

        datas.add("红烧牛肉面");

        datas.add("番茄炒鸡蛋");

        datas.add("农家小炒肉1");

        datas.add("农家小炒肉2");

        datas.add("农家小炒肉3");

        datas.add("农家小炒肉4");

    }



    public AddressFragment() {

        // Required empty public constructor

    }





    @Override

    public View onCreateView(LayoutInflater inflater, ViewGroup container,

                             Bundle savedInstanceState) {

        View view=inflater.inflate(R.layout.fragment_address, container, false);

        initView();

        lv= (ListView) view.findViewById(R.id.listview);

        adapter=new ArrayAdapter<String>(view.getContext(),

                android.R.layout.simple_list_item_1,

                datas);

        lv.setAdapter(adapter);



        Log.e("-------------view", String.valueOf(view));//测试结果View不为空



        srl= (SwipeRefreshLayout) view.findViewById(R.id.swip_refresh);

        Log.e("-------------cs", String.valueOf(srl));//测试结果srl为空

        srl.setColorSchemeResources(

                android.R.color.holo_blue_light,

                android.R.color.holo_red_light,

                android.R.color.holo_orange_light,

                android.R.color.holo_green_light);

        srl.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {

            @Override

            public void onRefresh() {

                new Handler().postDelayed(new Runnable() {

                    @Override

                    public void run() {

                        datas.add(0,"你是不是傻啊？");

                        datas.add(0,"你是不是傻啊？？");

                        datas.add(0,"你是不是傻啊？？？");

                        datas.add(0,"你是不是傻啊？？？？");

                        datas.add(0,"你是不是傻啊!!");

                        adapter.notifyDataSetChanged();

                        srl.setRefreshing(false);



                    }

                },3000);

            }

        });





        return view;

    }
