Android 在actionbarsherlock中实现列表时出现空指针异常

我想用actionbar sherlock片段显示一个简单的列表。下面的代码是一个程序的一部分，当用户单击选项卡时将执行该程序。代码在活动中使用时运行良好，忽略json部分

对于（inti=0；i试试这个

在调用函数之前，将
ListView lv；
更改为Global初始化
ListView

 ListView lv;
 @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        // Get the view from fragmenttab2.xml
        View view = inflater.inflate(R.layout.listview, container, false);


         lv = (ListView) view.findViewById(R.id.listView1);
         initList();
            SimpleAdapter simpleAdapter = new SimpleAdapter(FragmentTab2.this.getActivity(), employeeList, android.R.layout.simple_list_item_1, new String[] {"employees"}, new int[] {android.R.id.text1});
            lv.setAdapter(simpleAdapter);




        //Intent intent = new Intent(FragmentTab2.this.getActivity(), Favourites.class);
        //startActivity(intent);
        return view;
    }

在
initList（）
function reomve
ListView lv=（ListView）getView（）.findViewById（R.id.ListView 1）；
对于片段，
getView（）
方法返回
null
，直到返回
onCreateView（）
方法。在
onCreateView（）
方法中，调用
initList（）
在其中调用
getView（）
方法，该方法返回
null

尝试将
ListView
作为参数传递给
initList（）
…我对您的代码做了一点修改
