所有。   当我使用notifyDataSetChanged（），列表视图显示顺序将改变。

像这样

1

在当前activy已创建。但是当我改变数据。这将是

我不希望的顺序改变，我不明白为什么它的发生。

这是一张code从我的适配器类

 公共静态类ItemAdapter延伸BaseAdapter {        私有String [] MDATA;        私人LayoutInflater mInflater;//我叫这种方法来改变数据        公共无效setEditText（INT位置，最后弦乐项）{            MDATA [位置] =项目;            notifyDataSetChanged（）;        }} 

我在一些像这样的对话框更改数据

  =建设者新AlertDialog.Builder（CT）;                            builder.setTitle（R.string.pickStatus）                                    .setView（edBuffer）                                    .setPositiveButton（R.string.save，新DialogInterface.OnClickListener（）{                                                @覆盖                                                公共无效的onClick（                                                        DialogInterface对话框，INT ID）{                                                    // TODO自动生成方法存根                                                    canPop = TRUE;                                                    。最后弦乐TMP = edBuffer.getText（）的toString（）;                                                    KbonezLog.e（的String.format（套入钥匙％D键））;//使用MDATA键设定值setEditText（键，TMP）;dialog.dismiss（）;}}） 

解决方案

我已经遇到了类似的问题here

我通过始终创造getView（）implemantation新ViewHolder解决它。

所以我觉得罗曼盖伊提供正确的途径解决的问题，例如种。

希望工程。

all. when I use notifyDataSetChanged(), the listview display order will be change .

like this

1

when current activy was created. but when I change the data. it will be

I don't want the order changed and i dont understand why its happening.

This is a piece of code from my adapter class

    public static class ItemAdapter extends BaseAdapter {

        private String[] mData;
        private LayoutInflater mInflater;

// I called this method  to change data
        public void setEditText(int position, final String item) {
            mData[position] = item;
            notifyDataSetChanged();
        }



}

I change data at some dialog like this

       builder = new AlertDialog.Builder(ct);
                            builder.setTitle(R.string.pickStatus)
                                    .setView(edBuffer)
                                    .setPositiveButton(R.string.save, new DialogInterface.OnClickListener() {
                                                @Override
                                                public void onClick(
                                                        DialogInterface dialog, int id) {
                                                    // TODO Auto-generated method stub
                                                    canPop = true;
                                                    final String tmp = edBuffer.getText().toString();
                                                    KbonezLog.e(String.format( "set into key %d", key)); 
//use mData key to set value
setEditText(key, tmp);
dialog.dismiss();
}})

I've encountered a similiar problem here

I solved it by always creating a new ViewHolder in getView() implemantation.

So I think Romain Guy provide the correct way to solving such kinds of problems.

Hope it works.
