The specified child already has a parent.

求各位大神帮我看看，我这段程序哪里出现了父类？
final SimpleAdapter mSchedule = new SimpleAdapter(this, grouplist, R.layout.groupinfo, new String[]{"groupinfo", "groupinfotext"}, new int[]{R.id.groupinfos, R.id.groupinfotext})
{
//在这个重写的函数里设置 每个 item 中按钮的响应事件
@Override
public View getView(int position, View convertView, ViewGroup parent) {
final int p = position;
final View view = super.getView(position, convertView, parent);
Button button = (Button) view.findViewById(R.id.btnstate);
button.setOnClickListener(new View.OnClickListener() {

                @Override
                public void onClick(View v) {

                    //警告框的写法
                    new AlertDialog.Builder(GroupActivity.this)
                            .setTitle("More")
                            .setMessage("你选中了" + String.valueOf(p))
                            .setPositiveButton("确定", new DialogInterface.OnClickListener() {
                                public void onClick(DialogInterface dialog, int which) {
                                    setTitle("点击了对话框上的确定按钮");
                                }
                            })
                            .create()
                            .show();
                }
            });
            return view;
        }
    };

    GInfoView.setAdapter(mSchedule);
    GInfoView.setDescendantFocusability(ViewGroup.FOCUS_BLOCK_DESCENDANTS);
    GInfoView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            Toast.makeText(getApplicationContext(),"被点击了！",Toast.LENGTH_LONG).show();
        }
    });
    //触发点击事件的函数
  setContentView(GInfoView);
}

@caozhy 我看了这篇文章，还是没找到我的错误啊？

今天写代码的时候出现了这个错误，功能很简单：在一个Activity中有一个ListBox，长按其中一条数据会出现编辑框，点击确定之后就跳转到令一个Activity
第一次进行跳转没什么问题，按返回键在按编辑就挂掉了，出现了下面的错误

The specified child already has a parent. You must call removeView() on the......
答案就在这里：The specified child already has a parent.
