Android：如何在自定义SimpleAdapter中删除项目时刷新列表

Question

我可以知道如何在自定义SimpleAdapter中删除地图列表项目后刷新ListView项目吗？

我已经用list.remove（position）成功实现了删除列表项，但是当我尝试调用list.notifyAll（）函数时，它却给了我错误消息，比如“java.lang.IllegalMonitorStateException：object not locked通过notifyAll（）之前的线程“。

我希望你能帮助我。这是自定义SimpleAdapter的代码。

public class DeleteAdapter extends SimpleAdapter { 

    Context context; 
    List<? extends Map<String, ?>> list; 
    int resource; 
    String[] from; 
    int[] to; 

    public FDeleteAdapter(Context context, List<? extends Map<String, ?>> data, 
      int resource, String[] from, int[] to) { 
     super(context, data, resource, from, to); 

     this.context = context; 
     this.list = data; 
     this.resource = resource; 
     this.from = from; 
     this.to = to; 
     // TODO Auto-generated constructor stub 
    } 

    @Override 
    public View getView(final int position, View convertView, ViewGroup parent) { 

     final View row = super.getView(position, convertView, parent); 

     final Button delete = (Button) row.findViewById(R.id.deletebut); 
     final TextView title = (TextView) row.findViewById(R.id.label); 

     delete.setOnClickListener(new OnClickListener() { 

      public void onClick(View view) { 

       deleteDialog xdialog = new deleteDialog(context, "Delete? ", position) { 

        @Override 
        public boolean onOkClicked() { 

         list.remove(position); 
         list.notifyAll(); 

         return true; 
        } 
       }; 
       xdialog.show(); 
      } 
     }); 

     return row; 
    } 
}; 

非常感谢您的帮助。

Answer 1

您应该调用适配器的notifyDataSetChanged()功能，而不是notifyAll()的名单上。

Answer 2

使用

this.notifyDataSetChange();
