android.view.InflateException：二进制XML文件行＃19：错误膨胀类片段

问题描述：

编辑：这不是重复的，我修复了NullPointerException并且它不再重复。请将其标记为重复。android.view.InflateException：二进制XML文件行＃19：错误膨胀类片段

感谢@Fondesa，我已经修复了NullPointerException。我已阅读另一个问题@Tunaki将其链接到，这是有帮助的。但它并没有完全解决我的问题。

我想在我的主要活动有一个listfragment，但有android.view.InflateException。任何帮助将非常感激。我一直坚持这一天。

这是错误日志。

发生故障的片段类。

FragmentListAdapter adapter; 

public ADlister() { 
    // Required empty public constructor 
} 

// TODO: Rename and change types and number of parameters 


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

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, 
         Bundle savedInstanceState) { 

    // Inflate the layout for this fragment 
    View view = inflater.inflate(R.layout.fragment_adlister, container, false); 
    listView =(ListView)view.findViewById(R.id.prodlistview_fragement); 
    Exxplore exxplore= (Exxplore) getActivity(); 
    results=exxplore.getlist(); 
    if(results!=null&&results.size()!=0) 
     lister(); 
    return view; 
} 
void lister(){ 
    int count=results.size(); 
    String produrls[]=new String[count]; 
    String prodname[]=new String[count]; 
    for(int i=0;i<count;i++){ 
     prodname[i]=results.get(i).getProduct_title(); 
     produrls[i]=results.get(i).getProduct_url();

@Override

    Exxplore exxplore= (Exxplore) getActivity(); 
    results=exxplore.getlist(); 

    lister(); 
} 

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

}

函数exxplore.getlist()返回Result类型的数组列表。

你有没有尝试将“android：name”的片段标签改为“class”？ –

@sunilsunny是的。仍然没有工作。 –

@Tunaki请解释，我想出了解决方案，我想自己回答。 –

答

首先，你需要在com.idiots.redundant.digiteyes_beacon.ADlister.lister（ADlister.java:64）来解决这个错误

Caused by: java.lang.ArrayIndexOutOfBoundsException: length=0; index=0 
at com.idiots.redundant.digiteyes_beacon.ADlister.lister(ADlister.java:64) 
at com.idiots.redundant.digiteyes_beacon.ADlister.onCreateView(ADlister.java:50)

修正了这个问题。还是一样的错误。我已经在这个问题上做了一些修改，请你再检查一次吗？ –

我找不到初始化适配器的位置。检查它是否为空或什么。并在这里检查。 ** com.idiots.redundant.digiteyes_beacon.ADlister.onCreateView（ADlister.java:50）** –

答

编辑

您的编辑后，你必须检查空列表onCreateView()：

if(results != null && results.size()!=0) 
    lister();

我修正了这个问题。请检查我的编辑。 –

@Fondesa如果count为0，那么for（int i = 0; i

谢谢。但其他错误仍然存在。请检查我的编辑。 –

答

你应该添加一个空检查对于结果 -

results = exxplore.getlist(); 
if (results != null && results.size() != 0) 
    lister(); 
return view;

答

Exxplore exxplore= (Exxplore) getActivity();

它不是理想的办法让你onCreateView()方法内Activity实例。请使用onAttach(Activity mActivity)方法来获取您的活动实例。

onAttach（android.app.Activity）不赞成它说 –

是的，你应该尝试onTtm（Context mContext）而不是.. –

是的。谢谢。虽然不是确切的问题。 –
