Android类扩展listview错误

我正在使用一个活动，在该活动中，我添加了意见。Android类扩展listview错误

例如创建一个类扩展列表视图， mycode的：

public class ListViewExample extends ListView{ 
     Context context; 
     ListView list; 

     public ListViewExample(Context context,String[] ListItems) { 
      super(context, null); 
      // TODO Auto-generated constructor stub 
      this.context=context; 
      this.ListItems=ListItems; 


      LayoutInflater layoutInflater = 
        (LayoutInflater)context.getSystemService 
        (Context.LAYOUT_INFLATER_SERVICE); 
      View view = layoutInflater.inflate(R.layout.list, this); 
     } 
    }

得到这条线上的错误， 视图视图= layoutInflater.inflate（R.layout.list，本）;

错误的logcat：

首先，你为什么这样做使用'延伸ListView'？想要定义自定义适配器，即自定义ListView？ – 2013-02-09 08:33:35

在我的应用程序中有一些动画，这只是我使用视图，这个视图添加到我的活动。 – Jeeva123 2013-02-09 09:11:30

View view = layoutInflater.inflate(R.layout.list, null);

试一下吧。该参数不带上下文，它需要一个可选的父亲ViewGroup。如果你不想使用它，通过null。

LayoutInflater inflater = activity.getLayoutInflater(); 
view = inflater.inflate(R.layout.your_layout, null);

通过延长

public class yourclass extends BaseAdapter

这可能帮助你..
