从customadapter调用其他Activity/CustomAdapter

在我的代码中，我只使用了两个listview和两个CustomAdapter用于这两个listView，其中第一个listview是通过CustomAdapter实现的，从此CustomAdapter我只想调用另一个（Activity/Other对于第二个列表视图定制适配器）。它提供了异常像从customadapter调用其他Activity/CustomAdapter

java.lang.IllegalStateException：系统服务不提供给活动的onCreate（）之前

private LayoutInflater mInflater; 
    ViewFlipper vfWall; 
    ImageView ivComments; 
    TextView tvComments; 
    ListView lvComments; 
    WallCustom2 adapterForComments; 
    ImageDownloader imageDownloader = new ImageDownloader(); 
    private static final String[] URLS = 
    {

    }; 
    String[] itms={"hey dude kya kar raha hai.........."}; 

    public WallCustom(Context context,ViewFlipper vfWall,ImageView ivComments,TextView tvComments,ListView lvComments) 
    { 
     this.ivComments=ivComments; 
     this.tvComments=tvComments; 
     this.lvComments=lvComments; 
     this.mInflater = LayoutInflater.from(context); 
     this.vfWall=vfWall; 
    } 

    public int getCount() 
    { 
     return URLS.length; 
    } 

    public Object getItem(int position) { 
     return position; 
    } 

    public long getItemId(int position) { 
     return position; 
    } 

    public View getView(final int position, View convertView, ViewGroup parent) { 
     // TODO Auto-generated method stub 
     final ViewHolder holder; 
     if (convertView == null) 
     { 
      convertView = mInflater.inflate(R.layout.wallcustom, null); 
      holder = new ViewHolder(); 
      holder.Image = (ImageView) convertView.findViewById(R.id.ivImageWallCustom); 
      holder.Message= (TextView) convertView.findViewById(R.id.tvMessageWallCustom); 
      holder.comments= (TextView) convertView.findViewById(R.id.tvExtraWallCustom); 
      convertView.setTag(holder); 
     } 
     else 
     { 
      holder = (ViewHolder) convertView.getTag(); 
     } 

     if(imageDownloader.download(URLS[position],holder.Image)!=null) 
     { 
      holder.Image.setImageBitmap(imageDownloader.download(URLS[position],holder.Image)); 
     } 
     holder.Message.setText("hey dude kya kar raha hai.........."); 
     holder.comments.setText("Comments "); 

     holder.comments.setOnClickListener(new View.OnClickListener() 
     { 
      public void onClick(View v) 
      { 
       if(imageDownloader.download(URLS[position],ivComments)!=null) 
       { 
        ivComments.setImageBitmap(imageDownloader.download(URLS[position],ivComments)); 
       } 
       tvComments.setText(itms[position]); 
       Wall wallobj=new Wall(); 
       adapterForComments=wallobj.ListViewForComments(); // gives object of second custom adapter 
       lvComments.setAdapter(adapterForComments); // lvComments my second list view in which i want to set second custom adapter 
       vfWall.showNext(); 
      } 
     }); 

     return convertView; 
    } 

    class ViewHolder

     ImageView Image;

发布自定义适配器的代码。 – 2011-02-11 13:12:30

java.lang.IllegalStateException: System services not available to Activities before onCreate()

该错误消息非常直截了当。您正试图从活动的构造函数或初始化程序中使用系统服务，例如LayoutInflater。最早不要尝试使用LayoutInflater，直到onCreate()。

您可能正在使用无法使用的systemServide（InflaterService），直到调用oncreate（）事件。所以控制台的错误信息是直截了当的。
